Do not over-buy before your first class. For no-gi you need a rashguard and grappling shorts or spats (no pockets, zippers, or buttons). For gi training you need a jiu-jitsu gi and a belt — but most academies lend one for a trial, so wait until you have decided to commit before buying your own. That is genuinely the whole starter list.
BJJ gis use an "A" sizing system based mostly on height and weight: as a rough guide, A1 fits roughly 5’2″–5’6″ and 110–155 lbs, A2 around 5’6″–5’9″ and 155–190 lbs, and A3 around 5’9″–6’0″ and 190–225 lbs. These vary by brand and the gi shrinks slightly with hot washes, so always check the specific manufacturer’s chart before ordering. Women’s ("F") and kids’ ("M") sizing run on their own scales.
You do not need knee braces, fancy grip trainers, supplements, or a closet full of gis on day one. Ear guards are only worth it if you start developing cauliflower ear. Spend on a quality gi and good hygiene first; everything else can wait until you actually know what you need.
BJJ Gyms is an independent directory, not a gym. We feature 10th Planet Jiu-Jitsu as our recommended no-gi system. Always take a free trial and vet any academy yourself before committing.
For no-gi: a rashguard and grappling shorts. For gi: a jiu-jitsu gi and belt, though most gyms lend one for your trial. Add a mouthguard and sandals for off the mat. That is essentially all a beginner needs.
BJJ gis use the A1/A2/A3 system based on height and weight — for example A2 fits roughly 5’6″–5’9″ and 155–190 lbs. Sizing varies by brand and gis shrink a little when washed hot, so always check the manufacturer’s specific chart.
It is strongly recommended. A mouthguard is inexpensive and protects your teeth during scrambles and accidental contact, making it one of the few pieces of protective gear worth buying right away.
