Kids BJJ Gi Size Chart
Kids’ gi sizes follow height first, then weight. Measure your child barefoot against a wall, find that height in the chart, and use weight to double check. If they’re at the top of a range, go up one size, but don’t buy a gi that’s far too big. A loose jacket gives training partners more to grab and gets in the way when your child is drilling.
The same chart works for boys and girls. The full set of charts is in our BJJ gi sizing guide.
How to choose a kids BJJ gi
- Ask the coach first. Some academies want white, or a specific color, for class. Black, white and blue are the colors used in competition. The rest (green, navy, gray, pink, orange, red, yellow) are for everyday training.
- Check the fit by moving. Your child should be able to reach overhead, squat and sit in closed guard without the jacket pulling at the shoulders or the pants pinching.
- Think about a second gi. Two gis mean a clean one is always ready while the other dries, and each one wears more slowly.
- Wash it gently. Cool water, then hang to dry. Heat is what shrinks and fades a gi. Our product care guide has the details.
One gi or a 3-pack?
If your child trains once a week, a single gi is usually enough. If they train several times a week, a 3-pack means a clean gi is always ready while the others dry, and the cost per gi is lower. Whichever you choose, check the size first, since a pack is harder to exchange than one gi.
Gis for girls and boys
Our kids’ gis are unisex. Girls can pick any color, including pink, and use the same size chart as boys. Plenty of kids start in white or blue and add a color later.
Returns, in plain words
You have 30 days from receiving your order to return or exchange a gi. It needs to be unwashed, unused and undamaged, with the tags still attached and the belt included. So try it on at home with the tags on before class. If we sent the wrong item or a defective one, tell us within 10 days and we’ll send a prepaid return label. Exchanges are limited to one per order, and the customer pays return shipping on an exchange. Full details are in our returns and exchange policy.
What to wear with the gi
Most kids are more comfortable with a fitted layer under the gi. Look at kids rash guards, kids spats and kids no-gi shorts for no-gi days, and a kids BJJ belt for the next rank.
