I happen to have a LEGO basketball set on my desk... Eyeing it up
against a ruler, it is 14mm in diameter.
Depending on design choice, one might consider using only LEGO
basketballs or soccer balls because other materials would have different
physical properties. Wood will have a different rolling friction
characteristic than LEGO plastic. It would also be a different density.
Also (possibly worth noting), the LEGO basketballs are NOT perfectly
round: the stripes on the ball are recessed grooves. I do not have a
soccer ball handy to compare, so I'm not sure if that is a sphere with a
painted on soccer ball pattern or if it has ridges for the polygon
shapes.

Soccer balls, like Ruffles, have ridges...
