Basketball
Basketball rims, or hoops, are orange painted goals attached to the backboard and used for scoring points in a game of basketball. Basketball rims today are designed as breakaway rims comprised of a hinge and spring that allow the rim to bend when a player dunks without shattering the backboard. The rim itself is made of a 5/8” | 1.6 cm steel diameter steel rod that is formed into a ring with an inner diameter of 18” | 45. 72 cm. Basketball nets are hung from the bottom of the rim with lengths between 15”-18” | 38.1-45.7 cm. Basketball rims are mounted 10’ | 3.05 m from the court floor.

Basketball is a team sport in which two teams of five players score points by shooting (throwing) a ball through an elevated hoop located on either side of the rectangular court. To advance the ball down the court, players must bounce the ball (dribble) or pass it to a teammate.

High standards for high sport
Basketball is equally exciting at professional and amateur levels. However, if at home or in the yard you can hang a ring made with your own hands from improvised materials, then official games and training use equipment made in accordance with strict standards.
Fig. 1. Emblems of the NBA and FIBA
Regulations are drawn up by the two main sports organizations: FIBA and NBA. The standards of the first are used in international competitions, including world championships. FIBA recommendations are taken into account in the production of backboards, baskets, nets, marking on the sites.
FIBA recommends
The main attribute of the game is a basketball hoop with a backboard. This is a construction of a support with upholstery, a rectangular canvas - a shield, a metal rim and a mesh. Durable materials are used for production:
- hard wood;
- shatterproof tempered glass.
Standard size - 1.8 x 1.05 m. Fluctuations in length no more than 3 cm, in height - a maximum of 2. The lower part of the shield should be at a height of 2. 9m above the floor.
Fig. 2. Backboard Standards
The basketball hoop is made from steel. Rim thickness - 16–20 mm. Design color is orange. The inner diameter is 45–45.9 cm. The mesh is attached to the ring in 12 places. Sharp edges, cracks, chips, dents, other irregularities that can injure the player are not allowed.
The fastening of the ring to the shield must be such that the pressure on the hoop is not transmitted to the protective shield. There should be no contact between the ring and the shield. The upper edge of the ring is placed parallel to the floor at a height of 3.05 m. The discrepancy is only 6 mm.
Basketball net is made from durable white cord. In length, it should be 40-45 cm. The upper part is usually more rigid than the lower one. This is necessary so that the net does not overlap on the ring, does not get confused, allowing the ball to fall freely down.
NBA recommendations differ
The National Basketball Association is slightly conflicting regarding standards and centimeters. The differences are as follows:
- from the floor to the lower edge of the shield - 2.75 m;
- from the lower edge of the shield to the ring - 0.31 m.
Board markings
The markings are available in black and white. However, the color is not chosen at the whim of the organizers of the competition. White is used when the shield is glass. Black - if the surface is painted in a light tone. Line width - 50 mm. The size of the inner rectangle is 59 x 45 cm. Deviations in length are allowed no more than 20 mm, in height - 8. There is a ring at the base of the rectangle. The height from the lower edge of the shield to the ring is 148–150 mm.
Examples of standard boards
Fig. 3. Basketball backboard
SportStandard presents basketball backboards with and without hoops, made of Plexiglas and painted wood. Designs comply with FIBA and NBA standards, can be used for games and training. For sports competitions, the shield art is optimal. 091800 size 1800 x 1050 mm. For training, a smaller design, for example, art. 091700.

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.
Non-international competition courts 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 conditionally 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 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 with a length of 2.99 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 once 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.
