Kids swim shorts – Size guide

⚠️ Important sizing note:
Our kids swim shorts are designed with a secure, athletic fit and feature an integrated compression liner. The fit is supportive and not loose.
The shorts have a mid-thigh length (not above the knee), designed for comfort, freedom of movement, and a modern swim fit.
For growing children or if your child is between two sizes, we recommend choosing the next size up for extra comfort.

How to Measure Your Child

• Waist: Measure around the natural waist where the waistband sits
• Hips: Measure around the widest part of the hips
• Height: Measure from the floor to the top of the head

Measurements should be taken without tightening the tape.

Fit, Length & Comfort

• Mid-thigh length (not above the knee)
• Elastic waistband for comfort and flexibility
• Integrated compression liner for support and security
• Designed for swimming, beach activities, and active play

The compression liner is intentionally snug to ensure proper support and to prevent movement in the water.

Drawstring Information

• Sizes 4, 6 and 8: elastic waistband without drawstring
• Sizes 10, 12 and 14: elastic waistband with drawstring for added security during swimming and active use

Size Recommendation

• Choose the size based on your child’s waist measurement
• If your child is between two sizes, we recommend sizing up
• For taller or fast-growing kids, sizing up is recommended

Teen Size Notice

Size 14 is designed for teenagers and is not equivalent to an adult size S.
For teens with an adult body shape, please refer to our adult swim shorts size guide.
