My boys haven't tried these on yet, but I wanted to share the measurements since I had a hard time figuring out what size to buy. For the Peewee Regular, it is just under 8 inches across at the elastic waist, with the elastic unstretched. The length is pretty long at 8.5 inches from waist to crotch. However, I imagine the elastic could be rolled over to bring the rise down as it's a wide elastic band. The packaging specify said it's for ages 4 to 6 with a waist of 22 to 23 inches. The cup seems size appropriate and not too bulky.
