How big is a basketball court in metres

The International basketball Federation (FIBA) rules, dictate that

A full size FIBA regulation size basketball court measures exactly 28 by 15 meters.

In the National basketball Association (NBA), the court is 28. 7 by 15.2 metres.

In Australia, backyard half-courts generally start in size from about 7metres in height to fit the "free-throw line" (or 9m to fit the "three-point line") and 4 or 5 metres in width and upwards. Other popular sizes include; 9m x 5m, 10m x 7m and the FIBA 3x3 regulation sized 15m x 11m half court.

Basketball Court Lines

All lines should be 5cm in width and should be painted in a single colour throughout (usually white).

Hoop

In amateur basketball, court sizes can vary widely. One thing that remains identical on all basketball courts are the baskets (also known as hoops) are always 3.05 m (10ft) above the floor (except in some youth competitions).

Three Point Arc

The FIBA regulation three point arc is 6.75 m away from the basket. Any shot made outside of the three point arc is worth three points instead of the normal two. The distance from the hoop to the three point arc varies for under different regulations:

	Arc Radius from Hoop	Minimum Distance from Sidelines
FIBA	6. 75 m	0.90 m
NBA	7.24 m	0.91 m

Basketball courts have a three-point arc at both baskets. The three point line is not part of the three-point field goal area.

Free Throw Line

The free-throw line is 4.6m from the backboard. This is an important measurement for backyard basketball court construction, although the key width (3.6m) is often shrunken to fit the space without effecting gameplay , the key height (specifically the distance of free throw line to the backboard) should be maintained at 4.6 metres in order to effectively practice regulation free throw shooting at home.

No-Charge Semi-Circle (Restricted Area)

The no-charge semi-circle lines consist of a semi-cicle with a radius of 1.25m measured from the point on the floor directly under the exact centre of the basket to the inner edge of the semi-circle. The semi-circle is joined to two parallel lines perpendicular to the endlines, 0. 375m in length and ending 1.20m from the inner edge of the endline.

* The NBA three-point line is 0.91 m from the sideline in a zone starting at the baseline and ending when it crosses the 7.24 m arc. The 6.70 m distance exists only at the points on the three-point line that are directly to the left and right of the basket centre.

† The FIBA three-point line is 0.90 m from the sideline in a zone starting at the baseline and ending when it crosses the 6.75 m arc. The 6.60 m distance exists only at the points on the three-point line that are directly to the left and right of the basket centre.

The NBA, the NCAA and the National Federation of State High School Associations dictate that the free-throw line is 4.57 m horizontally from the plane of the front of the backboard.

Regulation FIBA vs NBA

In Australia, the most popular choice of backyard court line marking sizing is to adhere to the International Basketball Federation (FIBA) rules and regulations. FIBA regulation size courts are reasonably close to the NBA regulation size, in both total court size and specific court lines. Although the most significant difference between the two is the three point line, which is 49cm further away from the hoop at the arc, than FIBA regulation.

Basketball court markings: standards and norms

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 site. 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.

The size of the basketball court depends on the level of the competition, the governing organization, and the age of the students. Often, for training sessions or fights in amateur tournaments, different sizes of the playing court are used, but also in basketball there are officially established standard sizes of the field.

FIBA ​​and NBA Basketball Court Sizes

According to International Basketball Federation (FIBA) rules, the court must be rectangular and measure 28 by 15 meters (91.9 by 49.2 feet). However, in the overseas version of basketball, where the ruling organization of this sport is the National Basketball Association (NBA), the dimensions of the field for professional competitions are slightly different - 28. 7 and 15.24 meters (94 by 50 feet).

As for amateur basketball, the size of the fields can be completely different:

• For schools and universities: 21-28 m long, 12-15 m wide
• Mini basketball (for children under 12) - 17×12 meters

Basketball court markings

All field lines must be 5cm wide in white. The playing area is limited by the side and front lines. The middle line divides the court in half into equal parts. In the center of the middle line there is a circle with a diameter of 3.6 m (r - 1.8 m), where a dropped ball is played before the start of each period.

How many periods in basketball: the difference between FIBA ​​and NBA

There is an arc near each hoop at a distance of 6.75 m from the end line. Balls thrown into the basket outside it bring 3 points, everything inside the arc - 2 points.

Basketball's free throw zone is marked by a 3.6m line 5.8m from the endline and 4. 6m from the hoop.

The First Basketball Court Dimensions: A Brief History

The first basketball court was limited to the size of the college gym it was located in. That hall measured 54 by 35 feet (16.45 × 10.66 meters).

In 1891, James Naismith, a physical education teacher at Springsfield College in Massachusetts, invented a new game he later called basketball. At the first stages of the formation of a newly-fledged sport, peach baskets were used instead of rings, and in its first 13 rules, the creator did not indicate the size of the site. As basketball grew in popularity, it became necessary to standardize the size of the field. In 1924, the rules established the maximum size of the site - 28.65 by 15.24 m and the minimum - 18 by 9meters. The NBA still has such rules for the size of the court (28.65 by 15.24 meters), and FIBA ​​eventually set its own standard - 28 × 15 meters.
