Measure what fits
Lay a swimsuit your child wears now on a flat surface and measure it unstretched. It's more reliable than measuring a wriggling child.
Allow for stretch
Our swim fabric has four-way stretch and gives around 2–4 cm when worn, so a snug flat measurement is fine.
Between sizes?
Styles can vary by 1–2 cm. If you're unsure, size up for extra length and a longer season of wear.
Boys Boardshorts
Elastic waist with drawcord. Sizes 1 to 14.
