But how big is a basketball court?
Some of you know all the measures or maybe you’re missing a few. This article will clear up any doubts about the official dimensions of the NBA basketball court.

The height of the rim is identical in every league or federation, such as NBA, FIBA, WNBA, NCAA and Olympic Games.
