The Brazilian Jiu Jitsu belt system, explained

The adult belts run white, blue, purple, brown, black. Each carries up to four stripes, there is a separate colour system for children, and beyond black there are three red belts awarded for decades of contribution rather than for grappling. Getting from white to black takes most people around a decade.

That is the whole map. The rest of this page is what each rank actually signals and how a promotion gets decided, which is the part that surprises people arriving from martial arts with formal gradings.

The adult belts

• White — beginner. Survival, escapes, and learning the shape of the sport.
• Blue — competent. Escapes work, a guard exists, safe and useful to train with.
• Purple — dangerous. A recognisable game, real offence, and able to teach a beginner well.
• Brown — refined. Fewer holes, sharper detail, close to the finished picture.
• Black — expert practitioner, and the start of a much longer road rather than the end of one.

Under the IBJJF’s rules, which most academies follow whether or not their students compete, an adult belt starts at 16 years old for blue and 19 for black. Those are the two ages worth knowing; the rest is the coach’s judgement.

The system is unusually slow compared with other martial arts, and that is deliberate. A belt is meant to describe what happens when you roll, and what happens when you roll changes slowly.

Stripes

Each belt carries up to four stripes, taped onto the black bar at the end. They mark progress inside a rank, and they are the only signal most people get between promotions that can be years apart.

Two things are worth knowing. First, they are informal — the pace varies enormously between academies, and four stripes at one gym is not four stripes at another. Second, they are not required: plenty of coaches skip them entirely and promote straight between colours.

At black belt they become degrees rather than stripes, awarded on long timescales measured in years of teaching and involvement rather than in mat performance.

Children’s belts

Students under 16 use a different, longer ladder — white, grey, yellow, orange and green, each usually appearing in three variations (with white, plain, and with black) as a child moves through it. It exists for a simple reason: a decade-long gap between white and blue would be meaningless to a seven-year-old, and a child’s ranks should not imply adult capability.

At 16 a young student converts into the adult system. That conversion is a judgement, not an automatic swap of colour.

Beyond black

Three ranks sit above black belt, and they are honorary in character:

• Red and black (coral) — 7th degree.
• Red and white — 8th degree.
• Red — 9th and 10th degree, the highest rank in the art.

These are awarded for decades in the sport. A 9th-degree red belt is not somebody who out-grapples black belts; it is somebody who has spent a lifetime producing them. The 10th degree is historically reserved for the pioneers of the art.

You will almost never meet one, and that is the point.

How promotions actually happen

Most academies do not run a formal exam. A coach watches you over months, forms a view, and one evening lines the room up and calls your name. Common patterns:

• Batch promotions, once or twice a year, often around a seminar or the end of a term.
• On the day, whenever the coach decides — sometimes immediately after a competition.
• A grading, at academies that run one: a set of positions to demonstrate and a round or two to survive. Less common, and usually a formality confirming a decision already made.

What is being judged is rarely a list. It is whether your Brazilian Jiu Jitsu holds up: whether your escapes work, whether you can be trusted with a beginner, and whether the room would be represented fairly by you wearing that colour.

Because none of this is standardised, comparing your timeline with somebody at another gym is close to meaningless. If you want a sense of the range, how long a blue belt takes covers what actually drives it.

What a belt does not tell you

It does not tell you who wins. A strong blue belt beating a light purple belt is an ordinary Tuesday, and nobody in the room finds it remarkable.

It does not tell you how long somebody has trained. Two years of five sessions a week and six years of one are different amounts of Brazilian Jiu Jitsu.

And it is a poor progress instrument for your own use, simply because it updates so rarely. Better signals exist, and they update weekly rather than annually.

What the belt does tell you, reliably, is roughly what to expect when you shake hands — how hard somebody is likely to be to submit, and how much care they will take with you. For a sport where you hand a stranger your neck, that is worth a lot.

Common questions

Can you be demoted? Effectively never in practice. Ranks are not withdrawn for taking a few years off; you come back the belt you left as, and usually rusty.

What if I move gyms? Your rank travels with you. A new coach may take a while before promoting you further, because they have not watched you train yet.

Do I have to buy a new belt each time? Yes, and it is one of the cheaper parts of the sport. Many academies hand you one at the ceremony.

Is the stripe count on my white belt worth tracking? As encouragement, sometimes. As a measure, no — it is the lowest-resolution feedback you will ever get about your training.
