Guide written by Danielle Smyth
Last updated on September 28, 2022

Little boys are always outgrowing their clothes, and seasonal items like swim trunks are something parents can count on needing to buy new every summer.

As a general rule, boys’ swim trunks hit either just above or just below the knees. The preferred length is a personal decision, but longer suits are thought to be more on-trend by some. These are also referred to as “board shorts” and have a narrower fit and look.

Shorter swim trunks are called “swim shorts” and are designed with looser fits as opposed to tighter, even shorter styles worn by adults and for competitive swimming.

Boys’ swim trunks are offered in toddler sizes and can go up to older boys’ size 20. Most of this swim attire is made from thin, quick-drying polyester material, with nylon mesh liners for support and to prevent chafing. Some have elastic waistbands, while others are made with drawstrings. Elastic will keep the trunks more secure on the waist. Many also come with pockets, which active kids will appreciate.

DWYM Fun Fact

Boys’ swim trunks come in so many different colors and patterns and are so comfortable that many kids wear them as regular shorts and keep them on all day. There’s really no reason not to, as long as they are happy and the trunks fit well. Just remember to wash them after daily wear. It is also a good idea to bring an extra pair when you go to the beach or pool.

The Little Boy Swim Trunks Tips and Advice

  • Look at the manufacturer’s size chart, and measure the child to figure out what size he needs. The trunks should not sag or be loose, but they should also not be too tight. Kids like to play by the pool and on the beach, so make sure the trunks are secure so they stay put.
  • Chlorine-resistant fabrics are great for boys who spend a lot of time in swimming pools.
  • UPF protection is another good feature to look for. Many little boys’ swim trunks come in fabrics that offer UPF 50+ protection.
  • You can probably find a swim trunk pattern that your boy will like, such as airplanes, tropical scenes or robots. Get his approval before buying, and he will be more likely to wear the trunks often.
