I am a big fan of NBA basketball, especially its history, so I have pretty good knowledge of the past players, teams and stats.

Experience
You should have asked me 5 years ago. I was a real nut back then... :)

Basketball Trivia (general) - Dimensions


Expert: Borko Bariæ - 2/17/2005

Question
What is the inside dimension of a regulation basketball hoop? Also what is the outside dimension of a regulation basketball?

Answer
The official NBA rules state 'Each basket shall consist of a pressure-release NBA approved metal safety ring 18" in inside diameter with a white cord net 15" to 18" in length'. The FIBA hoops is the same size.

Official NBA basketball size is 'Around channels 29 1/2" to 29 3/4", across channels 29 5/8" to 29 7/8" ', FIBA says 'maximum Circumference 78 cm (30.7")', and the NCAA 'maximum Circumference 30", seams 1/4" Max.'.

I hope this answered your question.
