The belts in order
For adults, Brazilian Jiu Jitsu has exactly five belts: white, blue, purple, brown, black. That's the whole ladder. After black belt the system continues in degrees earned over decades, ending in the coral and red belts covered below. Kids aged 4 to 15 progress through their own belt track before joining the adult ranks.
Two things make BJJ's system unusual among martial arts. First, it is slow: around a decade to black belt, which is longer than judo, karate, or taekwondo typically take. Second, it is stingy: there are no belt tests you can buy your way through at most academies, and promotion is a judgment call by your instructor, loosely bounded by federation minimums. A BJJ belt is closer to a professional reputation than a certificate.
The hard rules (what the IBJJF actually requires)
Most of the belt system is convention, but the International Brazilian Jiu-Jitsu Federation publishes real requirements for rank it recognizes. The load-bearing ones:
| Belt | Minimum age | IBJJF minimum time at previous belt | Typical real-world time |
|---|---|---|---|
| White | Any | Starting rank | 1 to 2.5 years |
| Blue | 16 | None published for white | 2 to 3 years at blue |
| Purple | 16 | 2 years at blue | 1.5 to 3 years at purple |
| Brown | 18 | 1.5 years at purple | 1 to 2.5 years at brown |
| Black | 19 | 1 year at brown | 8 to 14 years total from day one |
Note what's missing: there is no minimum time at white belt. Your first promotion is entirely your instructor's call, which is why it varies more than any other. And these are minimums, not schedules; almost nobody is promoted at the floor.
What each belt actually means
White belt
The job at white belt is not winning; it is surviving, showing up, and building a base: escapes, posture, a functional guard, and the humility the first year beats into everyone. If you are here now, the white belt guide covers what to focus on and what to ignore.
Blue belt
The first promotion with weight behind it. A blue belt can defend themselves against an untrained person with room to spare and has a complete, if shallow, map of the sport. It is also the most common quitting point in BJJ, famous enough to have a name: blue belt blues. The blue belt guide goes deep on both.
Purple belt
The rank where a personal game appears. Purple belts stop collecting techniques and start connecting them; many academies let purples run warmups or teach fundamentals. Most people who reach purple go on to black: the great filter is behind them.
Brown belt
Refinement. The brown belt's game is already black-belt shaped; what remains is sharpening details, filling the last gaps, and, at most academies, helping teach. The IBJJF requires only one year here, the shortest mandated stay of any colored belt.
Black belt
Not the end, the beginning of the long half of the system. Black belts accrue degrees over time: the early degrees come at multi-year intervals, and from 7th degree onward the belt itself changes color.
After black: degrees, coral, and red
Degrees on the black belt accumulate over decades of continued practice and teaching. At 7th degree the belt becomes the red-and-black coral belt; at 8th degree, red-and-white coral; at 9th degree, the solid red belt. The 10th degree red belt belongs to the art's founding pioneers and is not awarded today. Coral belts are rare enough that the community knows them by name; the coral belt guide covers those ranks properly.
Stripes
Between belts, most academies award up to four stripes per belt: tape on the black bar of your belt, at your instructor's discretion. There is no universal standard for what a stripe means, and some academies skip them entirely. Treat them as what they are: a signal that the path is moving under your feet during promotions that can be years apart, not a currency that transfers between gyms.
The kids system
Athletes aged 4 to 15 have a separate track: grey, yellow, orange, and green belt groups, each with solid, white-striped and black-striped variants. At 16 a kids-system athlete converts into the adult ranks, typically entering at blue belt if their instructor judges them ready. The kids track exists so children are not measured against adult standards, and so a 16-year-old green belt with a decade of mat time is not called a white belt.
How long it all takes, honestly
Add the typical stays together and you get the honest answer: 8 to 14 years to black belt for someone training two to four times a week, with 10 as the folk median. Training frequency moves the number more than anything else, which is why averages mislead: three sessions a week for four years is more mat time than one session a week for a decade.
That is exactly what the belt timeline calculator models: put in your training pace and current rank and it projects a realistic range for every belt ahead of you, floor-checked against the IBJJF minimums above.
The one rule that overrides this page: your instructor promotes you, not a website and not a federation. Everything here describes the system honestly, but the system has one door, and your coach holds it.
