The Zone gymnastics leotards are designed for a close, flexible fit. Use actual body measurements rather than age alone wherever possible. For leotards, girth is especially important because it reflects the full length of the torso. If measurements fall between two sizes, the larger size is usually the better starting point.

For gymnastics leotards, girth is the key measurement when the numbers point to different sizes. If height or chest suggests one size but girth sits closer to the next, choosing the larger size will usually give a more comfortable torso fit.
How to Measure for The Zone Gymnastics Leotards
Measure over underwear or close-fitting clothing using a flexible tape measure. Stand naturally and keep the tape comfortably against the body without pulling it tight.

Girth
Key MeasurementUsing a flexible tape measure, start at the centre of one shoulder. Bring the tape down the front of the torso, through the crotch and back up to the same shoulder, creating one complete loop.
Keep the tape comfortably close to the body without pulling it tight. Girth is especially useful when choosing between two leotard sizes.
Chest
Measure around the fullest part of the chest, keeping the tape straight and level around the body. The tape should sit comfortably without compressing the chest.
Waist
Measure around the natural waist, usually the narrowest part of the torso. Keep the tape level and comfortably close to the body.
Hips
Measure around the fullest part of the hips and seat while standing naturally. Keep the tape level all the way around.
Hips are not included in this particular The Zone size table, but they can still be useful when checking overall body proportions and leotard coverage.
Height
Stand straight without shoes, with feet flat on the floor, and measure from the floor to the top of the head.
The Zone uses numbered gymnastics sizes rather than standard clothing sizes. Current girls' styles commonly progress from size 24 for younger children through sizes 26, 28, 30 and 32, with size 34 moving into Women's Small on many models. Use age only as a guide and prioritise actual body measurements, particularly girth, when choosing a leotard.
