Critical Dimensions to Consider When Building Your Court

Key/Lane

The key also called the lane, varies in size in professional NBA courts and college/high school courts. The key for a professional court is 16 feet wide, whereas a college/NCAA court and a high school court has a key that is 12 feet wide.

Regulation basketball courts have a backboard that extends out 4feet of the baseline and into the key. The 6ft arc or half-circle extends away from the basket from the foul line, completing the key.

Foul Line

All courts should have a foul line distance that is 15 feet from the foul line to the front of the backboard. In many cases, people confuse this measurement and think it is from the center of the basket and the front of the rim.

3 Point Line/Arc

The measurements for the 3 point line/arc vary in the following ways:

Professional basketball courts have a 3 point line that is 22 feet to the center of the rim on the sides and a straight line that extends out 16 feet 9 inches from the baseline. From those points, the line extends out from the center of the rim 23 feet 9 inches.

College basketball courts have a 3 point arc that is 20 feet 9 inches, whereas high school basketball courts have a 3 point line that is 19 feet and 9 inches in size.

Restricted Arc

This is a semi-circular arc that is drawn around the area that is underneath the basket. For NBA courts, this arc has a radius of 4 feet from the center of the basket. In college courts, the arc has a radius of 3 feet from the center of the basket.

Backboard and Rim

All levels of basketball, from NBA to high school, have a regulation distance of 10 feet from the ground to the top of the rim. A regulation backboard measures 6 feet wide by 42 inches tall with all rims being 18 inches in diameter. The inner square of the backboard measures in at 24 inches wide and 18 inches tall.
