Swimming Gear Size Guide for Kids
Swimming gear should stay comfortable and secure in the water. Goggles, caps, suits, and fins all fit differently, so start with comfort and seal before buying performance-focused gear.

FAQ
Should kids' swim goggles be tight?
They should seal without painful pressure. The eye cups should stay briefly without the strap when pressed gently into place.
Do beginner swimmers need fins?
Not always. Use fins only if the coach or swim program recommends them, and check shoe-size fit carefully.
