I have anecdata for that: I wear a size 2 in pants, have tiny child hands, and my gynos usually use the smaller of the speculums (though I doubt they use a child's size). And my uterus is a full 7 cm! I even used a Diva Cup comfortably for years (pre-PIV, too), even though that's one of the biggest menstrual cup styles. Granted, it was the smaller of the two because I wasn't over 30 yet, but it's still long and wide.
Parity has a bigger impact on the size of menstrual cup and diaphragm than body size. I assume the same would be said for contraceptive sponges.
