Frequently Asked Questions (FAQs)

1. How should boys swim trunks fit?

Your swim trunks should first fit around your waist. Not too high. That is, not covering your belly button. They should fit at the middle of your hip bone.

2. What should boys wear for swimming?

Boys can wear swim trunks or even swim briefs or jammers if they like. Try not to let the swim trunks run too long so that it interferes with their kick. Their trunks should stop just above their knees.

3. Should you size up in swim trunks?

Order a size larger when you're between sizes. Swimming trunks naturally fit tighter than a pair of casual shorts or jeans. Look for a pair with drawstrings if possible, which will allow you to adjust the fit until it's right.

4. Should swim trunks be tight or loose?

Ideally, you want to be able to pinch between a 1/2″ to 1” on either side of your thigh. You can go up a little bit if you must but any more and you're right on the edge of looking a little bit baggy and sloppy. The waist should fit perfectly around without too much sagging or tightness.
