How to Measure

Height: Have the swimmer stand barefoot and measure vertically from the top of the head to the floor.

Chest: Measure around the fullest part of the chest, keeping the measuring tape horizontal.

Waist: Measure around the natural waistline without pulling the measuring tape too tight.

Hips: Measure around the fullest part of the hips and seat while standing naturally.

Choosing Your Arena Size

Arena girls' training swimwear is designed for a close, comfortable and secure fit in the water. Age provides a useful starting point, but actual body measurements should be used when selecting a size.

If the swimmer falls between sizes, compare height, chest, waist and hip measurements rather than choosing a size based only on age.

If you are unsure which size is right, contact Aqua Style with the swimmer's measurements and our team can assist with sizing.

Please note: This guide applies to Arena girls' regular and training swimwear. Arena girls' Powerskin racing suits use a separate racing size chart.
