Size Help
Use your height, weight, body shape, and training fit preference to choose with confidence. If you are between sizes, send your measurements before ordering.
Measure first
Stand straight and barefoot. Height is the first filter for jacket length, sleeve length, and pant length.
Use your current weight. Weight helps confirm the shoulder, chest, waist, and overall comfort range.
Wrap the tape around the fullest chest point and natural waist. Keep the tape level, not tight.
Tell us if you want a closer competition fit, a relaxed training fit, or room for a growing athlete.
How to choose
The size chart is a starting point. If your height and weight point to different sizes, prioritize the fit issue that matters most: sleeve and pant length for taller athletes, chest and waist comfort for broader builds, and growth room for kids.
Hi Ground Kingz, I need size help. Height: __ cm. Weight: __ kg. Chest/waist if available: __. I want the Gi for training/competition/kids growth room.

Shrinkage and care
Ground Kingz Gi fabric is treated during production to reduce shrinkage. In textile manufacturing, this is generally called pre-shrinking: the cotton fabric is deliberately relaxed and mechanically stabilized before cutting and sewing, so most of the movement happens before the Gi reaches you.
Shrinkage should be minimal when you wash cold and hang dry. Cotton can still react to heat, so avoid hot washing and high-heat tumble drying if you want to preserve the chosen fit.
