Basketball Court Measurements

The correct dimensions of an NBA sized-basketball court are summarized below from the NBA Rules Book.

The National Basketball Association used to have to be concerned with local and far-away teams trying to manipulate the basketball court measurements and this has thankfully been alleviated thank goodness. Winners never cheat and cheaters never win!

National Basketball Association Official Size and DimensionsThe NBA lays out the official size and dimensions as well as markings of a basketball court that is going to have an official NBA game played upon.

Here is a little portion of how exacting a science the measurements of a basketball court have to be and how the NBA takes this very seriously.

Getting to Know the Court

First, the NBA basketball court should measure a long 94 feet from baseline to baseline. The sideline to sideline measurement is to be 50 feet. The line that exactly divides the entire full court is referred to as the half-court line.

The half-court line is to be marked 47 feet from either baseline. The ‘jump circle’ at half-court must have a 2 foot radius and be surrounded by a second circle that has a 6 foot radius.



3-Point Range is Really Out There in the NBA

Whenever an NBA launches a three-pointer during a game the range that the league mandates is a lengthy 22 feet! The 3 point arc in the NBA is 22ft to the center of the rim on the sides (The arc starts 5 feet 3 in from the baseline, being a straight line until that point) then the curved part of the arc is 23ft. 9 in. from the center of the rim.

The backboard of an NBA goal is 72 inches wide by 42 inches high. The official NBA backboard and one that is usually utilized in the NCAA College games unless it is a woman’s game has an 18 inch diameter rim.

The inner square which is the bulls-eye and target for beginning shooters, is marked above the rim in a rectangle of 24 inches wide and 18 inches high. This little red square can be utilized for bank-shots as well as a target for launching a game-winning half-court shot to beat the Knicks!

The Key – Where Angels and Shorty’s Fear to Tread

This very popular area for all basketball games and not just the NBA high-flying games is a 12 foot -section of the court. The key is where all the action transpires and some of the most entertaining moves on the court happen right here!

From gigantic eye-popping posturized slam dunks to sweet behind the back-passes to a cutting guard the key is where it is at! The players that are normally located within the key are the center and forwards.

A guard with either enough height or the jumping ability to equalize the tremendous height advantage displayed by most NBA players can sometimes be found trolling in the key.
