Funky Trunks Boys' Size Chart

Find the right Funky Trunks size for boys' training jammers and swimwear. The size shown on our product pages is the UK and US number, which is different from the Australian number printed in some Funky Trunks size guides.

Age is a starting point only. Measure your swimmer's waist and hips and choose the size those measurements fall into.

How to Measure

Waist: Measure around the natural waistline, keeping the tape close to the body without pulling it tight.

Hips: Measure around the fullest part of the hips and seat while standing with feet together.

Choosing a Junior Size

Boys' training jammers should sit snugly at the waist without digging in, so they stay in place during pushes off the wall and dives.

If your measurements point to two different sizes, contact Aqua Style with your measurements and the product name before ordering, and our team will help you choose.

Please note: This guide covers Funky Trunks boys' swimwear. Teenage swimmers with a waist above 80 cm should use the Funky Trunks Men's Training Size Chart.
