Our gymnastics leotards are made in Marseille, France, so they use European sizing. If you are shopping from the United States or the UK, this conversion chart will help you pick the right size in seconds, with measurements in inches.

Quick answer: EU to US leotard sizes

For women's leotards, take the EU size and subtract 32 to get the US size: EU 36 = US 4, EU 38 = US 6, EU 40 = US 8, and so on. For the UK, subtract 28: EU 36 = UK 8. Girls' leotards are sized by age (8, 10, 12 and 14 years), so the best guide is your gymnast's measurements rather than her age.

Measurements are body measurements, not garment measurements. A gymnastics leotard is meant to fit close to the body, so these figures already allow for the stretch of the fabric.

How to measure your gymnast

Chest: measure around the fullest part of the chest, under the arms, keeping the tape horizontal.
Waist: measure around the natural waist, just above the belly button.
Hips: measure around the widest part of the hips.

Use a soft tape measure directly on the body, flat but not tight, ideally over light underwear. Write down the three numbers, then find the size where all three fit. If the measurements fall into different sizes, choose the larger one: a leotard that is slightly roomy is far more comfortable than one that pulls on the shoulders.

Between two sizes?

Gymnasts grow fast, and a leotard should allow free movement for handstands, splits and dismounts. When in doubt, go up one size, especially for long-sleeve and 3/4 sleeve leotards, where the length of the body matters as much as the width. On every Startner product page, our interactive size guide lets you enter your measurements in inches and recommends the right size automatically.

Girls' sizes vs women's sizes

Our girls' leotards run from 8 to 14 years. Teenagers who are tall or have a more developed figure often move to women's sizes from 12 or 13 years old: compare the chest and hip measurements rather than the age. Women's sizes run from EU 36 (US 4) to EU 48 (US 16).
