I just double-checked, to be sure. Almost every spin control uses a commonly defined maximum of 5000mm.
It seemed big enough, much larger than needed to make any avatar or space monster. They are unsigned short integers, so the max could be 65,535. A creature with a 65m femur would be pretty big.

When you add an odd number of breasts, the odd one is centered between the first pair, to make a row of three. Others form pairs down the abdomen. There was a female character in Total Recall that had a row of three, also in Futurama.
