Kingz Kids BJJ Gi Size Guide
Find your child's size below. These are suggested body measurements for Kingz kids and youth Brazilian Jiu Jitsu gis. M-sizes are scaled for younger practitioners without excess bulk — there's room to allow for growth, but not so much that the gi swims on the mat.
| Size | Suggested Weight | Suggested Height |
|---|---|---|
| M0000 | 30 – 40 lbs / 13 – 18 kg | 3'6" – 3'9" / 1.07 – 1.14 m |
| M000 | 40 – 50 lbs / 18 – 22 kg | 3'9" – 3'11" / 1.14 – 1.19 m |
| M00 | 50 – 60 lbs / 22 – 27 kg | 3'11" – 4'2" / 1.19 – 1.27 m |
| M0 | 60 – 70 lbs / 27 – 31 kg | 4'2" – 4'5" / 1.27 – 1.35 m |
| M1 | 70 – 80 lbs / 31 – 36 kg | 4'5" – 4'8" / 1.35 – 1.42 m |
| M2 | 80 – 90 lbs / 36 – 40 kg | 4'8" – 4'11" / 1.42 – 1.50 m |
| M3 | 90 – 100 lbs / 40 – 45 kg | 4'11" – 5'1" / 1.50 – 1.55 m |
| M4 | 100 – 110 lbs / 45 – 49 kg | 5'1" – 5'3" / 1.55 – 1.60 m |
Detailed jacket and pants measurements (A–F dimensions) are on the chart image below.
How to find your child's size
- Weight first — weight is the most reliable anchor for how the jacket fits across the chest and shoulders.
- Then height — height tells you whether the sleeve and pant length will be right. Sleeves should reach near the wrist bone; pant legs just above the ankle.
- Room to grow — Kingz kids gis include a 6-loop cord drawstring on the M3 and M4 sizes for adjustability, and an elastic waistband on smaller sizes. Some growing room is built in, but don't size up by more than one slot or the jacket will hang too loose on the mat.
- Care — cold wash, air dry. Heat will shrink the gi out of the size you chose. M-size gis are partially pre-shrunk and may move 3–5% with hot washing.
