Ignore the fact the hand is as thick as a servo motor, for now, and just consider the palm width.

This 4-finger hand is just below 4 inches wide, across the knuckles. By the standards of gloves for humans, this is already "X-Large"

The SCS0009 servos are 1/2in wide and there are two for each finger. Adding two more servos would make it 5 inches wide, taking it into "XXX-Large" territory.
