Gymnastics Size Chart

At GK, we’ve been outfitting the world’s top athletes for over 40 years. Through our experience, we’ve learned that the most accurate way to ensure a proper fit is to rely on body measurements. Although an individual’s perception of fit may vary greatly, the GK Fit is scientifically engineered to move with the athlete for optimal performance.

Measuring athletes takes the guess work out of selecting their size. It is quick, easy, reliable, and helps to achieve a similar fit for all team members.

How to Measure

1. Chest: Measure around the fullest part of the athlete’s chest, arms down while taking a deep breath, keeping the measuring tape horizontal.

2. Waist: Measure around the narrowest part of the waist (typically where your body bends side to side), keeping the tape horizontal.

3. Hip: Measure around the fullest part of the buttocks, feet together, keeping the tape horizontal.

4. Torso: Measure from the center of the shoulder, down the torso, through legs, and back to the shoulder. This is the most important measurement.

5. Inseam: Measure from the crotch to one inch above the floor, without wearing shoes.

Please use the following Measuring Forms when measuring your athletes for their apparel. The forms will help you organize each athlete's measurements, so that selecting their size is easy and straight forward.

The following size charts have been designed to ensure that taking accurate athlete measurements will result in the correct size being ordered. When an athlete's measurement contains a partial inch, always round up to the next full inch. If an athlete's measurements fall across two sizes, order the larger size. Remember to always make sure that the size chart matches the style you are ordering.

Please use the following style reference guide to ensure that you request the proper sizing set. Sizing sets should be ordered based on which style number you intend to order.
