The above chart shows the 2013 IBJJF Pan Kids BJJ Weight Classes, and includes kids jiu jitsu weight classes for Might-Mite, Pee-Wee, Junior, and Teen divisions. There are different weight requirements depending upon the type of gi the child or teen wears to compete and weigh-in. A light weight gi, or summer kimono, and a single weave gi (which is slightly heavier than a summer gi).
