ANSWER 18 inches in diameter ANSWER 18 inches in diameter, but really it just depends if it is NBA Basketball, collage or a different type of basketball, some basketball rings are different.
They size of an ice rink can vary but the standard size in North American is 200' long x 85' wide. I believe that all of the NHL rinks conform to this size and if any rinks in NA are smaller, it is generally in the length of the rink.
In Europe, the size can vary, but they are generally 200' long x 100' wide.
So, what about the size of the rink for the Winter 2010 Olympics to be held in Vancouver? My guess is that it most likely will be 200' x 85'.
