Basketball is a sport that is played on a rectangular court with two baskets on opposite ends. The dimensions of a basketball court vary depending on the level of play and the specific rules and regulations of the league or organization. For example, the National Basketball Association (NBA) has different court sizes than high school or college basketball. So, when asking how many yards long a basketball court is, it is important to specify the level of play and the specific rules being followed.

What You'll Learn
NBA court length and width
A basketball is roughly 9 inches in diameter, or 0.625 feet, or 0.21 yards.
The National Basketball Association (NBA) boasts the largest court dimensions of any level of basketball, be it domestic or international. The outer dimensions of an NBA court are 94 feet long by 50 feet wide. The half-court line is halfway between each end line. The tip-off circle in the middle of the half-court line has a 6-foot radius and often sports the home team's logo. The key, also known as "the paint", is 16 feet wide and 19 feet from the baseline to the foul line. A semicircle with a 6-foot radius extends from the foul line. The backboard protrudes 4 feet out from the baseline, and the rim of the basket hangs 10 feet off the ground.
The three-point line is one of the most recognisable aspects of a basketball court's dimensions. The first instance of the three-point line appeared in the American Basketball League in 1961, but the league folded soon after. In 1967, the American Basketball Association (ABA) adopted the three-point line, and when the NBA and ABA merged in 1976, the three-point line was not included. The three-point line is 22.15 feet from the centre of the hoop in the WNBA, and 20 feet, 9 inches in the NCAA.
The free throw circle is 3.6m in diameter, the same size as the centre circle. Shooters must stay inside this circle when taking a free throw, and the circle is also used for jump balls. Lane lines run from the free throw line to the baseline to form the "key". The shape and width vary depending on the level of the game. The backboard is 1.8m x 1.22m, with a minimum thickness of 19mm. Nets are typically white and are suspended from the hoop, with a minimum length of 45cm.
The optimum width of a basketball court is 50 feet, and the half-court length is 47 feet. Residential half-court setups are also possible, especially if space is limited.

College court size
The standard basketball court size for college play is 94 feet long and 50 feet wide. In yards, this equates to approximately 30.62 yards long and 16.4 yards wide. The total playing area is 502.31 yards squared, or 810 yards squared if run-offs and sidelines are included.
The free throw lane, or "the key", is 12 feet wide for college play. The three-point line is 20.75 feet away from the basket, and the rim of the basket hangs 10 feet off the ground.
The court size for junior high and middle school players is smaller, at 74 feet long and 42 feet wide. The high school court size is 84 feet long and 50 feet wide, with the same "key" width as the college court.
The largest basketball court dimensions are used in the NBA, with outer dimensions of 94 feet long and 50 feet wide, and a key width of 16 feet.

High school court dimensions
A basketball court is 30.62 yards long and 16.4 yards wide. The total playing area is 502.31 square yards, and 810 square yards if you include the run-offs and sidelines. The court is divided into two halves, with each team having a basket at their end.
Basketball court dimensions vary depending on the level of competition. High school basketball courts are smaller than professional and college courts. The standard size for a high school basketball court in the US is 84 feet long by 50 feet wide, or 4,200 square feet. The recommended safety zone around the court is between 3 and 10 feet, bringing the total area to between 5,100 and 6,800 square feet.
The inner court markings for the "Foul Line", backboard dimensions, and rim size remain the same across different levels of play. The free throw lane, also known as "the key" or "the paint", is 12 feet wide for high school play and extends 15 feet from the backboard to the free throw line. There are three 6-foot circles on the court, one in the centre and one on each end centred on the foul line. The three-point line is 5 feet 3 inches from the outer boundary line of the court.
The basketball goal, also known as the ring or hoop, is typically 18 inches in diameter and positioned 10 feet from the floor. The backboard protrudes 4 feet out from the baseline. Nets are usually white and suspended from the ring, with a minimum length of 45 cm.
In the UK, Sport England outlines four levels of play: International, Premier (national competition), Club (regional competition), and Community (schools/recreational). This allows for flexibility in court sizes. The minimum court size is 85.3 feet in length and 45.93 feet in width. The total area of a professional basketball court is 420 square metres, while the minimum area allowed under Basketball England's guidance is 364 square metres.

Olympic court measurements
The Olympics usually feature a smaller basketball court than the NBA, with the court measuring 49 feet in width and 92 feet in length, compared to the NBA's 50 feet by 94 feet. In the metric system, the Olympic basketball court is 28 metres by 15 metres, or 28.7 by 15.2 metres according to another source. This is the size of a FIBA-regulation court, which is used in the Olympics and is slightly smaller than the NBA court. The FIBA 3-point line is also shorter than the NBA's, allowing for improved accuracy from deep.
Olympic basketball games are played on a rectangular court by two teams of five players each. The objective is to score points by shooting the ball into the basket or hoop, which is always 10 feet or 3.05 metres above the ground. The baskets are located at each end of the court within a painted area called the key, free throw lane, or shaded lane. The key is used to prevent players from staying beneath the opponents' basket for long periods (more than three seconds). In the NBA, the key is 16.02 feet wide, while for FIBA tournaments, it is wider at 4.9 metres by 5.8 metres.
The three-point arc is a line located at a certain distance from the basket, and any shot made outside this line is worth three points instead of the usual two. The FIBA three-point arc is 6.75 metres from the basket, while the NBA's is 7.24 metres at the top of the arc. The free-throw line, where players stand when taking a foul shot, is located within the three-point arc and is 4.6 metres from the backboard.
The 3x3 basketball event, introduced at the Tokyo Olympics, is played on a half court with eight teams competing in one large group. The winner is determined by the team with the most points after a 10-minute period or the first team to reach 21 points.

Junior high court size
A basketball court is 30.62 yards long and 16.4 yards wide. The total playing area for a standard court is 502.31 yd². The court is divided into two halves, with each team having a basket at their end. The court markings indicate the playing area, as well as the locations of the key, the three-point line, and the free-throw line.
The size of a basketball court can vary depending on the level of competition and the space available. For instance, the NBA has the largest court dimensions, with a length of 94 feet and a width of 50 feet. High school courts are usually 84 feet long and 50 feet wide.
Junior high school players typically use a smaller court size of 74 feet long and 42 feet wide. This court size is also mentioned as the smallest recommended full-court size, used for elementary school play. This smaller court size is more suitable for younger players and can be adjusted to fit within available space constraints.
The free-throw line, also known as the foul line, is 15 feet from the front of the backboard, and this distance is consistent across all courts. The key, or free-throw lane, has a width of 12 feet for junior high school basketball, while the three-point line distance varies depending on the level of competition.
Basketball courts can be constructed indoors or outdoors, with variations in materials and dimensions. Indoor courts are typically made from hardwood, while outdoor courts can be asphalt or concrete. The ceiling height for all courts should be a minimum of 16 feet, with higher levels of play requiring more space.
