Might consider that wrist size is usually going to indicate joint size, one of the main factors in handling heavy weights. Big boned/big joints are designed for this, because by nature the ligaments/tendons give more support to the actual force of motion that the muscles give. It's a body bio-mechanics thing.
Larger elbow and shoulder joint structures will bench and overhead press more. As larger hip/knee/ankle joints will squat more. There is a strength correlation, or even muscle size, linked the wrist size. Though you may not want to be carried away by that theory too much.
Plenty of lifters, who may have average or small wrist measurements, who are hosting huge weights. Like double bwt benches or triple bwt squats. Can watch them at most any PL'ing meet. And BB'ers, with average or smaller joints, displaying outstanding muscle size. Whatever the wrist size, it should not put a limit on what you want out of lifting. So I guess it really doesn't matter what the wrist may measure, just go for your personal potential. Good Luck.
