Starting BJJ raises a lot of practical questions before you ever step on the mat. This guide rounds up the answers, from gi sizing to what your first class actually looks like.

BJJ guides exist because starting the sport raises a lot of practical questions that have nothing to do with technique — what to wear, how classes are structured, whether the gear is worth buying, and how hard the learning curve really is. This page rounds up the essential guides every beginner needs, organized by the order these questions actually come up.
The most common hesitation before starting BJJ is simply not knowing what to expect. Is BJJ hard to learn? covers the honest learning curve, and Brazilian Jiu-Jitsu classes: what to expect as a beginner walks through exactly what a typical class looks like, so the first session isn't a total unknown.
BJJ has its own vocabulary and rules that take time to absorb. What is guard in BJJ? explains the position that defines much of the sport. Brazilian Jiu-Jitsu weight classes covers how competition divisions work, and is BJJ an Olympic sport? answers a question that comes up constantly given the sport's growing global profile.
Buying your first gi is genuinely confusing without guidance. How should a BJJ gi fit? and the BJJ gi size chart together cover sizing from both a fit-feel and measurement-chart angle. Once you're training regularly, how to tie a BJJ belt is a genuinely useful skill most new students fumble through their first few classes.
BJJ is a full-contact sport, and a few precautions go a long way. Is cauliflower ear dangerous? and taping fingers for BJJ cover two of the most common physical concerns new grapplers run into. On the equipment side, are BJJ dummies worth it? and are BJJ instructionals worth it? help you decide where extra training spending actually pays off versus where it doesn't.
Most new students move through roughly the same sequence: deciding whether to start (learning curve, class structure), understanding basic vocabulary and rules, buying a properly fitting gi, then picking up injury-prevention habits and evaluating extra gear as they settle into regular training. The guides above are organized in that rough order, but each stands alone if you're looking for a specific answer.
