Everything You Need to Know About Basketball Court Dimensions
Of the two major American-invented sports — baseball and basketball — only one has gained worldwide popularity. We play baseball across parts of the globe, but we play basketball worldwide. You can play with as few as two people and as many as ten. Shoot hoops indoors and outdoors and on any surface hard or flat enough to bounce a ball.
Indoor courts are usually made from hardwood, though other, more easily-maintained surfaces are gaining in popularity. Outdoor courts can be either asphalt or concrete. You can put a permanent basketball court just about anywhere you would like. Don’t have the room for a full-length court? Fitting just a half court into your driveway, backyard, or commercial gym would be just as useful.
So, have a space in mind and wondering “What are the dimensions of a basketball court?” Let’s take a look at the standard sizes for every level of basketball, from high school all the way up through international competition.
NBA Basketball Court Dimensions
The National Basketball Association, better known as the NBA, boasts the largest court dimensions of any level of basketball — domestic or international. The outer dimensions are 94 feet long by 50 feet wide. The half court line is, as the name would suggest, halfway between each end line. In the middle of the half court line is a tip-off circle with a six-foot radius, which often sports the home team’s logo.
The key is 16 feet wide and 19 feet from the baseline to the foul line. A semicircle with a six-foot radius extends from the foul line. Some courts have the other side of the half-circle drawn in a dotted line inside the key to complete the circle and create a clear boundary for any jump balls.
The backboard protrudes four feet out from the baseline, and the rim of the basket hangs 10 feet off the ground. Subtracting the four feet overhang from the 19-foot length of the key, we get the familiar 15-foot distance from the foul line to the front of the backboard. It’s a misconception that the foul line is 15 feet from the center of the basket. The backboard itself measures six feet wide and 42 inches high.
Inside the key, a four-foot arc is aligned with the center of the basket to designate the restricted arc. If a defender is inside this semicircle, he cannot draw a charging foul. Along both sides of the key, lines are drawn three feet apart to create the standing positions for other players during a free throw attempt, starting with a box that is seven feet from the baseline and one foot wide.
Outside the key, the three-point line forms an imperfect arc stretching one side of the baseline to the other. The arc isn’t a perfect circle because it would run out of bounds on the sides of the court.
Instead, the three-point line runs in a straight line from the baseline out 16 feet, nine inches, at which point the line begins to curve. The straight lines are an even 22 feet from the center of the basket, and on the arc, the distance is 23 feet and nine inches.
Starting at the baseline and running 28 feet toward the center of the court, a line bounds the team bench area. The line also acts as the starting place for inbounds passes after timeouts and fouls.
WNBA Basketball Court Dimensions
The Women’s National Basketball Association or WNBA’s court dimensions are identical to the NBA court in every way except the three-point line. Instead, the distance is equal to the International Basketball Federation (FIBA) at 22.15 feet from the center of the hoop. WNBA teams share arenas and playing surfaces with the NBA, which is why it’s no wonder the court dimensions are so similar.
NCAA Basketball Court Dimensions
National Collegiate Athletic Association or NCAA basketball courts have similar dimensions to the NBA and WNBA, which include the:
Court
Foul line
Backboard
Basket height
Tip-off circle
That said, there are a few significant differences in the dimensions of the NCAA court. For starters, the key is only 12 feet wide, rather than 16. The first box on the side of the key is only six feet from the baseline, not seven. The restricted area under the basket is also one foot smaller, at three feet in diameter rather than the NBA’s four.
However, the most recognizable difference between the NBA’s court dimensions and the NCAA’s is the distance of the three-point line. The NCAA three-point line is only 20 feet, nine inches from the center of the basket. Because of the smaller diameter, it is a continuous arc from one side of the baseline to the other, with no straight lines necessary to create space on the sidelines.
The difference in three-point line distances is the biggest adjustment for shooters to make as they begin their professional careers, and also why it’s so difficult to project how well a player will shoot in the pros.
High School Basketball Court Dimensions
High school basketball courts are a little different from their college and professional counterparts. The most noticeable difference is that the court is a full 10 feet shorter, measuring only 84 feet. However, there are some similarities. The court is still 50 feet wide. The basket is also 10 feet off the ground.
The tip-off circle has a six-foot radius, just like the big kid courts, and while the high school landscape isn’t as standardized as college and professional basketball, the backboard is supposed to have the same measurements as the NCAA and NBA.
Just as in college and professional basketball, the foul line is 15 feet from the backboard, and the key is 19 feet long. It’s also the same 12 feet wide as the NCAA — four feet narrower than the NBA and WNBA.
The other visible difference is the distance from the three-point line. Shorter than either the NCAA or NBA, the high school free throw line is just 19 feet, nine inches from the center of the basket. Additionally, high school basketball courts do not have any restricted area under the basket, since that rule doesn’t exist in high school basketball.
FIBA Basketball Court Dimensions
FIBA governs international basketball courts. The measurements for FIBA basketball courts differ from U.S. courts because of the difference between our Imperial measurements — feet and inches — and the more standard metric system.
FIBA courts are an even 28 meters long, which converts to almost 92 feet. The 15-meter width converts to just over 49 feet. The tip-off circle is a bit smaller as well, at 3.5 meters in diameter. This difference translates to a radius of about five feet, seven inches.
The key is almost the same size at 5.8 meters long and 4.8 meters wide. These numbers convert to within a few inches of 19 and 16 feet. The basket is 1.2 meters, or almost four feet, in from the baseline, which puts the foul line at 4.6 meters — 15 feet — away. The restricted area under the basket is 1.25 meters or just a shade more than four feet in radius.
The basket is still 10 feet off the ground, which means the biggest difference is the three-point line. At the top of the arc, the three-point line is 6.75 meters from the center of the basket or 22.15 feet. This measurement works out to about 22 feet, two inches. The FIBA three-point line, which has also been adopted by the WNBA, is over a foot and a half closer than the NBA line.
The History of Basketball Court Dimensions
Since its invention in 1891, basketball’s court dimensions have varied. Let’s look at some of its historical changes, as well as answering that nagging question — “Why are basketball hoops 10 feet high?” — below:
The Story Behind the 10-Foot High Hoop
It would appear the 10-foot basketball hoop is the result of a careful calculation that considers the human anatomy and mechanics of the game. After all, even the tallest players today have to jump to dunk a ball, and a ten-foot high rim gives a comfortable target to shoot for at a distance. But as we see so often in history, the truth is much more mundane.
When James Naismith dreamed up the game in Springfield, MA in 1891, the railing he chose to hang the baskets on was ten feet off the ground. So, while everything else about the sport has changed since that first game, the baskets are still right where Dr. Naismith hung them.
The History of the Three-Point Line
The three-point line is arguably the most recognizable aspect of a basketball court’s dimensions and part of the reason why is attributed to the history surrounding this semicircle.
The first instance of the three-point line appeared in the American Basketball League in 1961, a full 70 years after Dr. Naismith invented the game. The line was added to increase excitement, but the league folded in just one and a half seasons, so the idea never had a chance.
In 1967, the next competitor to the NBA arrived. The American Basketball Association, or ABA, instituted the three-point line from the very start, and it was a huge success. The ABA had many exciting innovations that produced a better product for the fans. But ultimately, there was not enough room for two professional basketball organizations, so the NBA and ABA merged in 1976.
The three-point line, however, was not included in the merger! The decision-makers in the NBA at the time were too stubborn to adopt such a radical change. They held out for three years before implementing the three-point line in the 1979-1980 season. The NCAA didn’t integrate it until 1986, and it didn’t arrive on high school basketball courts until 1987.
That isn’t the end of the story, however. The line was moved closer for three seasons in the ‘90s to try to boost scoring, but it was quickly moved back to its original place. Taking the idea to the extreme, the NBA has even admitted to having discussions about a four-point line. Ultimately, we’ll believe it when we see it.
The Original Cage Matches
In the early days of professional basketball, the game was played inside an actual cage. The reasons were more about practicality than about safety. The rule for who got to inbound a ball that left the court was “whoever got to it first,” so organizers took to putting up a cage so the ball could never go out of bounds in the first place.
Those first basketball courts were about a third smaller than they are today, and the cages provided a physical boundary and an extra immovable for savvy teams. Could you imagine how much different the game of basketball would be today if those cages had stuck around?
The Alternative Key Designs
Today, basketball courts at all levels share a common design for the key — a rectangle measuring either 19 feet by 16 feet or 19 feet by 12 feet. However, this was not always the case. From the creation of FIBA in 1956 until 2010, the key was a trapezoidal design that was significantly wider at the baseline.
Another design of this feature is responsible for the name “key.” Have you ever thought about how a rectangular area under a basket got such a random name?
The reason is that the original area was much narrower, while the circle surrounding the free throw line was the same size. These two factors combined to create a shape that resembled an old-fashioned key. In 1951, the key was widened to 12 feet and later to the 16 feet we see now in the NBA and FIBA.
While the term lives on, time has erased any record of its design and original reference. And for the record, the official name for this feature is “free throw lane,” which isn’t a phrase many of us hear often.
And that’s a wrap on the history of basketball’s court dimensions.
Build Your Basketball Court With PROformance
Perhaps you don’t have 94 feet of flat asphalt or indoor floor space. Don’t worry, because residential half court setups can be just as fun. And whether you are looking to paint your court or apply a pre-made solution, sticking to the official dimensions will take your pickup games to the next level.

Diagram and Measurements – Backyard Sidekick
The dimensions of a basketball court play an important role in how the game is played. For example, getting the right distance to the free throw line is a big deal when you’re going to spend hours and hours practicing.
The NBA (National Basketball Association) official court size is 94 feet long by 50 feet wide, where the international court is a bit smaller. The FIBA (International Basketball Federation) rules state the court size should be 91.9 feet long by 49.2 feet wide for international basketball games.
There are also different size courts for high school, parks, and some college basketball games, with different distances for line markings like the 3-point line. Keep reading for detailed dimensions and free diagrams of the different court set ups.
Even though basketball court dimensions will differ between organization or level of school, they aren’t too far off from each other either. Here’s a helpful chart to show the different basketball court dimensions quickly before we dive into more detail.
Court Type
Length
Width
Free Throw
3-Point Line
NBA
94′

NCAA

Notice how almost all of the free throw distances are 15 feet, or close to it. The 3-point line distance is pretty close across the board, but high school basketball courts are around 10 feet smaller and have a shorter 3-point line distance.
The good thing about the key and free throw line being the same across all court types, is that for home use, you can use something like this Easy Basketball Court Stencil Kit (link to Amazon) and still be practicing your free throws at the same distance the professionals do.
NBA Court Dimensions
An NBA court will be 94 feet in length by 50 wide, with the half court line at 47 feet, directly in the center of the court. The free throw line is 19 feet from the edge of the court and 15 feet from the front of the backboard. The 3 point shooting line is 23.75′ or 23’9′ from the center of the hoop.
Here’s a handy diagram of an NBA basketball court with dimensions.
Here are some more details about the court line markings and dimensions of an NBA basketball court.
Court Size – 94′ by 50′
The Key – 16′ wide with backboard extending 4′ onto the court into the key. A 6′ radius half circle extends away from the basket at the top of the key.
Foul Line – 19′ from the baseline (edge of the court) and 15′ away from the backboard.
3-Point Line – The 3-point line is 22′ feet from the basket on the sides of the court and 23’9″ from the basket around the arc of the 3-point line.
Restricted Arc – A half circle with a radius of 4′ under the basket where players can not draw charging fouls.
Backboard – 72″ wide by 42″ tall with an inner square 24″ wide by 18″ tall.
Rim/Hoop – Top of rim is 10′ from the ground and 18″ in diameter.
Line Markings – All line markings are 2″ wide.
FIBA Court Dimensions
A FIBA court will be 91.9 feet in length by 49. 2 wide, with the half court line at 45.95 feet, directly in the center of the court. The free throw line is 19 feet from the edge of the court and 15.09 feet from the front of the backboard. The 3 point shooting line is 22.15′ from the center of the hoop.
I was crazy to me that the international court dimensions were so weirdly close to college or NBA courts, but off enough to make things difficult. The reason being is that the international courts needed to be done in metric rather than feet and inches. So they came up with nice round numbers in the metric system that translates to odd and difficult numbers to work with.
If you look at the FIBA court dimensions in meters, it makes a bit more sense. A FIBA court is 28 meters long by 15 meters wide. These courts are necessary to play on if we want to play basketball in the Olympics and other international competitions.
Here’s a quick video explaining the differences NBA players have to overcome to play internationally.
College Basketball Court Dimensions
An NCAA basketball court will be 94 feet in length by 50 wide, with the half court line at 47 feet, directly in the center of the court. The free throw line is 19 feet from the edge of the court and 15 feet from the front of the backboard. The 3 point shooting line is 22.15′ from the center of the hoop.
The NCAA basketball court dimensions are very similar to the NBA with the exception of the 3-point line being slight closer. About a foot and a half distance can make a big deal if you get used to shooting on a college court and move to the NBA, but it doesn’t seem to be a big hurdle for the professional players.
High School Basketball Court Dimensions
A high school basketball court will be 84 feet in length by 50 wide, with the half court line at 42 feet, directly in the center of the court. The free throw line is 19 feet from the edge of the court and 15 feet from the front of the backboard. The 3 point shooting line is 19’9″ from the center of the hoop.
The high school basketball court key and free throw line matches the NBA distances. The court is about 10 feet shorter in length, but is the same width as a college level or NBA court.
The three point line is significantly closer to the hoop on a high school basketball court, partly because the court it shorter, but also to allow the players at that skill level an opportunity to make those 3-point shots.
Basketball Hoop Height
The top of the basketball hoop is 10 feet from the ground on all regulation basketball courts including the NBA, NCAA, FIBA, and high school basketball courts. Basketball rims, sometimes referred to as the hoop or basket, are a regulation 18 inches in diameter.
It’s recommended that 8 to 10 year olds play on an 8 foot rim height, and 11 year olds play on a 9 foot rim height. This way younger players can gradually get used to the height of a basketball hoop without being discouraged from playing the game early on.
Basketball Backboard Dimensions
The regulation dimensions of a basketball backboard are 72 inches wide by 42 inches tall with an inner square to help players aim for the backboard measuring 24 inches wide by 18 inches tall. This translates to a backboard 6 feet wide by 3.5 feet tall for regulation basketball courts.
Basketball backboards sold for recreational or training basketball play are sold in a variety of sizes. The most common being 60, 54, 52, 48, and 44 inches wide. For a typical two car driveway, a 54 or 60 inch backboard is most commonly used and is fitting for a court that size.
Here are some common questions I get about this topic.
How Long Is A Basketball Court In Meters?
A regulation NBA or NCAA basketball court measures 94 feet long by 50 feet wide which is 28.7 meters long by 15.2 meters wide. The FIBA international basketball courts are a little smaller and were designed using meters as a measurement coming in at 28 meters long by 15 meters wide.
How Far Is The 3 Point Line From The Basket In High School?
On a regulation high school basketball court the 3 point line is 19 feet 9 inches from the basketball hoop. The top of the rim is 10 feet from the ground and the front of the backboard is 4 feet in from the side of the court, making the free throw line 15 feet from the hoop.
Is NBA Court Bigger Than NCAA?
The regulation NCAA basketball court is the same size as an NBA basketball court at 94 feet in length by 50 feet wide. The only noticeable difference between the two courts is the 3-point line distance. The NBA 3-point line is 23.75′ from the hoop, where the NCAA is 22.15′ from the hoop.

Basketball court markings: standards and norms
Author of the article
Khvatkov Dmitry
Consultant in the production of rubber coatings
Basketball field marking requirements are approved by the FIBA standard. The site must be flat with a hard surface, free of bends, cracks and other obstacles. The accepted dimensions of the field are 28 m long and 16 m wide. By NBA standards, the field is slightly larger: 28.7 m (94' ft) long and 15.3 m (50' ft) wide.
Areas not intended for international competitions may differ from accepted standards (for public use, in schools or universities, etc. ) and usually vary from 20 to 28 m in length and from 12 to 16 m in width.
Basketball Court Marking Standards
Basketball court markings are conventionally divided into 5 components:
Boundary lines. They are located along the perimeter of the site and set its size. The lines that run along the field are called side lines, and those that are behind the baskets are called front lines.
Central line. Divides the court in half parallel to the front lines.
Central zone. It is a circle and is placed in the middle of the center line, and, accordingly, in the center of the entire field.
Three-point line. It is a semi-ellipse and is located around the shields on both sides of the field. It limits the close range.
Free throw line. It is located in front of the boards parallel to the front line and is limited on the sides by paint lines.
The standard line width is 5 cm. All outlines and lines must be of the same color (usually white) and be clearly visible from anywhere on the court.
Common lines
Common lines are used to limit the playing area of the court. The side lines (along the field) according to FIBA standards should be 28 m long, and the front lines - 16 m. For public areas, deviations from the accepted standards are allowed. Typically, basketball courts in schools or gyms are made from 20 m long and 12 m wide.
Central lines
The center line is parallel to the front and divides the field exactly in half. According to the standards - it should extend beyond the side lines by 15 cm on both sides.
In the middle of the center line there is a circle with a diameter of 3.6 m, which limits the central zone of the field. In this zone, the ball is played at the beginning of the game.
Three-Point Line
Three-Point Lines are located around the backboards on both sides of the field and consist of two straight lines 2.9 long9 m and a semicircle. Straight lines run perpendicular to the front at a distance of 0. 9 m from the side lines. Despite the fact that visually the distance from the ring to the side of the three-point line seems to be less than to its central part, the distance from the backboard to any point is 6.75 m.
Penalty lines
Penalty lines limit the nearest area at the backboard. They consist of a trapezoid and a free throw zone.
Despite the name, the "trapezium" is a rectangle (until 2009year it really was a trapezoid), which is located under the shield. Its dimensions are 5.8 meters long and 4.9 meters wide. The shield is located at a distance of 1.575 m from the end line in the middle of the court. In front of the backboard, at a distance of 1.25 m, there is a semicircle that limits the area for picking up the ball.
At a distance of 4.225 meters from the backboard, the trapeze zone ends and the free throw zone begins. It is a semicircle with a diameter of 3.6 m (like the central circle).
Paint zone lines
These lines are serifs on both sides of the trapezoid (parallel to the side lines). They limit the areas for players who are fighting for the ball during a free throw.
Zones on the basketball field
The basketball court is divided into zones using markings. Each zone has its own specific rules.
Center circle
The center circle is used as a separate kick-off area at the start of the game. One representative from each team stand in a circle from their side and fight for the ball in a jump, after it is dropped by the referee. All players are exclusively on their side of the field, except for one who rebounds on the opponent's side.
Neutral zone
The peculiarity of this zone is that as soon as the player of the attacking team with the ball crosses the center line and is on the side of the opponent, he cannot pass the ball to the player of his team who is on the other side of the field (i.e. behind center line on your side).
Three-point zone
The three-point line limits the near zone of the shot. Hitting the basket from outside the basket brings the team three points. If the throw was made inside the zone, then it brings two points.
Three-second zone
This is the zone in close proximity to the ring. It is called three-second, since the player of the attacking team cannot be in it for more than three seconds. Most balls are thrown in this zone, so when attacking, it provides maximum protection.
Free throw area
In controversial situations, a free throw is provided from this area. The player of the attacking team must score the ball without stepping over the line of the trapezoid. At the same time, the players of both teams are not in the three-second zone. They take up positions along the paint lines on the sides of the trapezoid and may not step outside the lines until the free throw shooter has shot the ball.
How to mark a basketball field?
Basketball field markings, whether it is an international competition court or an open-air amateur field, are best applied using special equipment. This will ensure the long life of the coating, the lines will not clog and will promote fair play.
You can order the marking of a basketball court in Moscow and the Moscow region from Rezkom. We will measure the premises and develop a design project for the field so that it complies with generally accepted rules and is convenient for operation.

Basketball court: markings, photo
Today basketball is one of the most popular and spectacular team sports. Its purpose is for the players of the opposing sides to move around the court, guided by special rules, and throw as many balls as possible into the baskets mounted on the backboards.
Basketball court
The field in this sport is a flat rectangular surface with a hard surface. It should not have any obstacles or projectiles around the entire perimeter.
Any gaming platform of official sports has its own standards, which are registered in the code of the respective federation. The International Basketball Association is called FIBA. It has the right to change the dimensions of the field, markings, the height of the boards, etc. According to FIBA standards, the basketball court must be 28 meters long and 15 meters wide. One of the main requirements of the association for the field is a flat and hard surface. The surface of the site must comply with generally accepted standards and have no bends, cracks or other obstacles. It is important that the field is a rectangle with an approximate aspect ratio of 2 to 1. Previously, the size of the basketball court (standard until 2011) was about 30 meters long and 15 wide.
It is worth noting that since the end of the 60s, according to the regulations, all official competitions must be held indoors. Until that time, tournaments could be organized outdoors.
Basketball court dimensions
There are two baskets with baskets and corresponding markings on the playing field. Along the edges there may be a fence in the form of a high fence (net) or a wall.
A basketball court for public use must be at least 26 meters long and at least 14 meters wide. Such playing fields may have an additional 2 meters of running margin. Thus, areas with dimensions of 30 by 18 m are allowed.
According to the regulations, a deviation in dimensions of 1-2 meters is allowed, but official competitions cannot be held at such sports grounds. The size of a basketball court in a school or university can vary from 12 to 16 meters wide and from 20 to 28 meters long. The fact is that municipal and amateur halls do not fall under the jurisdiction of FIBA. For mini-basketball, the dimensions of the court are 18 meters long and 12 meters wide. The main difference between this type and the main one lies in sports equipment, which is suitable only for small children.
For official tournaments, the dimensions of the basketball court must be 15 m wide and 28 m long. The measurement is taken from the inner edge of the lines that limit the playing area of the field. The height of the hall should not be less than 7 meters, but at professional venues it is customary to raise the level of the ceiling and the hanging scoreboard to 12 meters and above.
Another important requirement is luminescence. It is necessary that its sources do not interfere with the movement of the players and the ball, and the light covers the entire surface of the field along with the shields.
Basketball court markings
The playing field can be conditionally divided into five components, which are outlined by a special contour:
1. Boundary lines. Conducted around the perimeter of the entire site. The lines that run along the width are called front lines, and those that go along the length of the field are called side lines.
2. Central zone, which is a circle. The measurement is taken along the outer edge. Placed in the middle of the field relative to all 4 of its sides.3. Central line. It runs parallel to the facial lines. It is carried out from one side line to another.
4. The three-point line is a semi-ellipse. In fact, the entire basketball field is a zone of long-range shots, except for the area near the opponent's backboard.
5. Free throw line. It is applied to the surface parallel to the front line. Its length is limited by the penalty area.
All outlines and lines must be the same color. In most cases, white paint is chosen. The standard line width is 5 centimeters. The contour must be clearly visible from any point on the site.
Marking: common lines
The basketball court must be 2 meters or more away from spectators, benches, billboards and other obstacles. The playing field is limited by the side and front lines. The first represents the width of the rectangle, and the second represents its length. At the intersection point of the lines, there should not be any recognition contours, as in football. The front side of the site can be from 12 to 16 meters, and the side - from 18 to 30 m. The central line divides the field along the length into two equal zones. It is carried out through the middle of the side lines and should protrude beyond their edges by 15 centimeters on each side.
The center circle is located in the middle of the court relative to each of the boundary lines. Its radius to the outer boundary of the circle is 1.8 meters.
Marking the throw line
Before official competitions, the FIBA commission pays special attention to checking the penalty area. The marking of the basketball court with the dimensions specified in the regulations must strictly comply with international norms and rules adopted in 2011.
According to these standards, the three-point zone must be limited to two parallel lines that start and end at the same front line. The end point must be at a distance of 6.25 meters from the center of the opponent's basket. The distance between the points of intersection of the three-point line and the end line is 1.575 m.
The free throw area consists of limited areas that are semi-circles with a diameter of 3. 6 meters. It is indicated on the site by a dotted line from the inside and a solid line from the outside (side to the enemy). The center of the zone is located in the middle of the foul line, which is 3.6 m long. Throws are made from this area after violations by the opponent. It should be noted that the penalty line should be at a distance of 5.8 meters from the edge of the front line. There is one designation in the marking - the area of throws. From this zone, the players take the penalties earned on the opponent. The first line of the area should be at a distance of 1.75 meters from the front. It limits the area to a width of 85 cm. Next comes a neutral zone with a diameter of 0.4 meters. Following are two more penalty areas of 85 cm wide. Each of the lines should be 10 centimeters long.
Team bench area
The basketball court, in addition to the playing field, also includes areas for coaches and substitutes. Bench areas should be located on the same side as the scorer's table.
Limited to lines over 2 meters long. Bench zones can be either a rectangle or a square.
It is important that the substitute area is located at a distance of 2 meters or more from the site, and at least 1 m from spectators and billboards.
Optimum coverage
A specialized basketball court is a flat, hard surface on which players can move without any obstacles. Therefore, for the field, coverage is so important. It must be durable and resilient, as the site is constantly subjected to shock loads. The coating can be made from different materials, but the most common are rubber and parquet. It is important that the site is durable and resistant to many factors. Therefore, rubber coating is most often used, as it is versatile and waterproof. On the other hand, parquet is considered more environmentally friendly and reliable.
The flooring is laid in two stages: first, a diagram of the basketball court is made, then installation work is carried out on its basis.
It’s a misconception that the foul line is 15 feet from the center of the basket. The backboard itself measures six feet wide and 42 inches high.
For starters, the key is only 12 feet wide, rather than 16. The first box on the side of the key is only six feet from the baseline, not seven. The restricted area under the basket is also one foot smaller, at three feet in diameter rather than the NBA’s four.
The most noticeable difference is that the court is a full 10 feet shorter, measuring only 84 feet. However, there are some similarities. The court is still 50 feet wide. The basket is also 10 feet off the ground.
At the top of the arc, the three-point line is 6.75 meters from the center of the basket or 22.15 feet. This measurement works out to about 22 feet, two inches. The FIBA three-point line, which has also been adopted by the WNBA, is over a foot and a half closer than the NBA line.
So, while everything else about the sport has changed since that first game, the baskets are still right where Dr. Naismith hung them.
In 1951, the key was widened to 12 feet and later to the 16 feet we see now in the NBA and FIBA.
Here’s a helpful chart to show the different basketball court dimensions quickly before we dive into more detail.
75′
2 wide, with the half court line at 45.95 feet, directly in the center of the court. The free throw line is 19 feet from the edge of the court and 15.09 feet from the front of the backboard. The 3 point shooting line is 22.15′ from the center of the hoop.
Basketball rims, sometimes referred to as the hoop or basket, are a regulation 18 inches in diameter.
The NBA 3-point line is 23.75′ from the hoop, where the NCAA is 22.15′ from the hoop.
) and usually vary from 20 to 28 m in length and from 12 to 16 m in width. 
9 m from the side lines. Despite the fact that visually the distance from the ring to the side of the three-point line seems to be less than to its central part, the distance from the backboard to any point is 6.75 m. 
They limit the areas for players who are fighting for the ball during a free throw. 
If the throw was made inside the zone, then it brings two points. 
It has the right to change the dimensions of the field, markings, the height of the boards, etc. According to FIBA standards, the basketball court must be 28 meters long and 15 meters wide. One of the main requirements of the association for the field is a flat and hard surface. The surface of the site must comply with generally accepted standards and have no bends, cracks or other obstacles. It is important that the field is a rectangle with an approximate aspect ratio of 2 to 1. Previously, the size of the basketball court (standard until 2011) was about 30 meters long and 15 wide. 
The height of the hall should not be less than 7 meters, but at professional venues it is customary to raise the level of the ceiling and the hanging scoreboard to 12 meters and above. 
It is carried out through the middle of the side lines and should protrude beyond their edges by 15 centimeters on each side. 
6 meters. It is indicated on the site by a dotted line from the inside and a solid line from the outside (side to the enemy). The center of the zone is located in the middle of the foul line, which is 3.6 m long. Throws are made from this area after violations by the opponent. It should be noted that the penalty line should be at a distance of 5.8 meters from the edge of the front line. There is one designation in the marking - the area of throws. From this zone, the players take the penalties earned on the opponent. The first line of the area should be at a distance of 1.75 meters from the front. It limits the area to a width of 85 cm. Next comes a neutral zone with a diameter of 0.4 meters. Following are two more penalty areas of 85 cm wide. Each of the lines should be 10 centimeters long.
