A handful basketball diagrams and references are available here for your guide in making your own basketball court! Through these court diagrams, you’ll be able to see the common rules in making a basketball court, even though the dimensions in practice vary in overall length and width. In many areas of the country, older high school gymnasiums in particular have smaller overall size than regulation. Many of these same gyms have varying backboard designs and measurements. See the first diagram below.
The above basketball diagram shows you the 94×50 feet size court. Basketball courts come in different sizes. In the National Basketball Association (NBA), the court is 94 by 50 feet (28.7 by 15.2 m). Under International Basketball Federation (FIBA) rules, the court is minutely smaller, measuring exactly 28 by 15 metres (91.9 by 49.2 ft). A high school court is slightly smaller, at 84 by 50 feet (25.6 by 15.2 m). In amateur basketball, court sizes vary widely. The baskets are always 10 feet (3.0 m) above the floor (except possibly in youth competition). Basketball courts have a three-point arc at both baskets. More diagrams of basketball courts are posted below.
The NBA three-point line is 3 ft (0.91 m) from the sideline in a zone starting at the baseline and ending when it crosses the 23.75 ft (7.24 m) arc. The 22 ft (6.70 m) measurement applies only at a point where a line parallel to the baseline intersects the long axis of the court and the center of the basket. The FIBA three-point line is 2.95 ft (0.90 m) from the sideline in a zone starting at the baseline and ending when it crosses the 22.1 ft (6.75 m) arc. The 21.65 ft (6.60 m) measurement applies only at a point where a line parallel to the baseline intersects the long axis of the court and the center of the basket.
