Size Chart


At GK, years of pattern development have taught us that the most accurate way to ensure proper fit is to rely on body measurements. An individual’s perception of fit may vary greatly; however, 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.

Measuring Forms

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.

  • Men’s Gymnastics Measuring Form
  • Cheer Uniforms Measuring Form
  • Warm-Ups Measuring Form

  • Measuring Basics

    The goal of measuring is to determine the correct size to order for each athlete. In order to conduct a successful measuring session, you'll need three tools: size charts, measuring forms, and a measuring tape.

    Accurate measurements are vital to the proper fit of your athletes' apparel. Please make sure that all athletes are wearing fitted workout apparel during the measuring session.

    Chest Measurement
    First, measure the chest of the athlete while their arms are down at their sides. Have the athlete take a deep breath in while measuring at the fullest part of the chest. Your measuring tape should always be parallel to the floor while taking the measurement.


    Waist Measurement
    When measuring the waist, wrap the tape at the natural waistline which is the narrowest part of the waist. If you are having trouble locating the natural waist, have the athlete bend to the side. The natural waist is where the body bends. Again, the measuring tape should always be parallel to the floor while taking the measurement.


    Hip Measurement
    Take the hip measurement at the fullest part of the buttocks with the athlete's feet together. Ensure that the tape measure is parallel to the floor.


    Torso Measurement
    Take the torso measurement from the center of the shoulder, down the torso, through legs, and back to the shoulder. This is the most important measurement you will take measuring athletes for leotards, men's gymnastics competition shirts, and one piece cheer uniforms.


    Inseam Measurements
    Take the leg inseam measurement by running the tape from the crotch to one inch above the floor. Measure the athlete without shoes.


    Select the Correct Size

    The following size charts have been thoroughly evaluated to ensure that taking accurate athlete measurements will result in the correct size being ordered. To select the correct size, reference the appropriate GK size chart for the style being ordered to determine which size best corresponds to the athlete's measurements. 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.
