BJJ belt system explained: white, blue, purple, brown and black belts and stripes

TUREFF• •0

BJJ belts carry a reputation: they are said to be slow, hard-earned and largely free of the grading exams some other martial arts use. That reputation is broadly accurate. This guide explains the adult belt order, how stripes work, roughly how promotion happens and why nobody can give you a fixed timeline.

The adult belts

For adults the order is:

White: the starting belt.
Blue
Purple
Brown
Black

Beyond black there are degrees awarded over many years, and the very senior coral and red belts, but most people will never need to think about them. Children have their own system of colours, such as grey, yellow, orange and green, and move into the adult belts as they grow older. The IBJJF (International Brazilian Jiu-Jitsu Federation), the largest competition body, sets a minimum age of 16 for the blue belt.

Stripes

Many gyms add stripes, small strips of tape or cloth on the black bar at the end of the belt, to mark progress within a belt. Up to four stripes per belt is common, after which the next promotion may come. Stripes are a coaching tool, not a universal requirement: some gyms use them strictly, some loosely and some not at all.

How promotion works

In most gyms your coach decides when you are ready, based on what they see in class and in rolling. Some gyms run formal gradings or syllabus tests, particularly for the early belts. Things coaches typically weigh up:

technical knowledge for your level
how you perform in sparring against people at and around your belt
consistency, meaning how often and how long you have trained
attitude, safety and how you treat training partners
for some, competition results

The IBJJF publishes minimum ages and minimum time at certain belts for people registered with it, but those are floors, not targets, and gyms not affiliated with it set their own rules. Check the federation's current graduation rules if you plan to compete.

How long does each belt take?

There is no honest single answer, which is why the question gets argued about so much. Promotion depends on how often you train, previous experience in wrestling or judo, your age and fitness, injuries, life getting in the way, and your coach's standards. Someone training five times a week moves very differently from someone training once. What is broadly true:

White belt is where most people quit. Getting to blue is a real achievement.
The jumps get longer as you go up.
Black belt generally takes many years of consistent training.

Be cautious of any gym that promises a belt by a date, and of anyone who sells promotions as part of a package.

What each belt roughly means

These are loose descriptions, and every coach has their own view.

White: learning to survive, escape and recognise positions.
Blue: solid basics, can defend well and has a few attacks that work.
Purple: a developing personal game, linking techniques together, often starting to help teach.
Brown: refining and tightening everything, closing gaps.
Black: deep understanding and the ability to apply it, though most black belts will tell you it feels like a new start.

Wearing and tying the belt

Ask your coach to show you the knot; most gyms use a simple, secure one that stays tied while rolling.
Do not wear a belt you were not given by a coach.
In no-gi classes there is no belt, though some people wear a rank-coloured rash guard.

Keeping it in perspective

Belts are useful as a rough map, but they are not the reason most people keep training. The rounds, the problem solving and the people are. If you focus on improving a little each week, the belts take care of themselves. How long have you been at your current belt, and what helped you most?
