How Long Should My Swim Trunks Be?
Your men's swim trunks should stay above the knee. Any further and it inhibits much-needed mobility. This applies to board shorts too. Some of us prefer to show off a little bit more thigh and some of us like to keep the sun at bay. A good suggestion is to give your knees 3-4 inches of sunshine. Measure from your hip (where you'll tie off the trunks) to your knees to see how long your swimsuit needs to be to give you that extra movement when you're paddle-boarding, taking a breather, or diving in the pool. And don't forget to put on sunblock!
