The BJJ blue belt: requirements, how long it takes, and how blue belts train
By Scott Flear, founder of JitsAI. Rules from the IBJJF; numbers from 818 blue belts who told us how they train.
The blue belt is the second adult rank in BJJ. Under IBJJF rules you must be at least 16, and you spend at least two years at blue before purple. In JitsAI’s September 2026 data, 61% of 818 blue belts had trained for two to five years, and 63% compete.
What does a blue belt mean in BJJ?
Blue belt means the basics hold up under pressure. You can escape the common pins, defend the common submissions and play a guard against people at your own level. It is the first promotion every grappler works towards.
It is also where plenty of people stall. Wins get harder because your training partners improved too. Our articles on the blue belt blues and the plateau hiding in one position cover that stretch.
What are the IBJJF rules for a blue belt?
- Minimum age: 16.
- Minimum time at blue before purple: 2 years for adults. It is 1 year if you were registered as a grey, yellow or orange belt, and there is no minimum if you were a green belt, a juvenile blue belt or the adult blue belt world champion.
- Juveniles: 16 and 17-year-olds have no minimum time at blue.
- The belt: blue, with a black bar about 10 cm long near one end.
- Competition: adult blue belt matches at IBJJF events last 6 minutes. Find BJJ tournaments in the US or competitions in the UK.
How do stripes work on a blue belt?
Up to four stripes on the black bar, at the professor’s discretion. Because the two-year minimum only counts from the day the blue belt is registered with the IBJJF, stripes let an academy mark progress along the way.
How do people earn a blue belt?
There is no IBJJF minimum time at white belt, so the move to blue is the professor’s call. What changes is consistency: a blue belt can do the basics against resisting people, not only in drills.
Blue belts in our data have trained for between one and five years in 82% of cases, and only 3% for under a year. After blue, the IBJJF clock starts: at least two years before purple.
How do you prove progress between belts?
Belts move slowly, and stripes depend on your gym. JitsAI’s ladder proves progress between belts: every technique you test is scored against the kind of partner it worked on.
- One Focus a week, with pinned lessons from Henrique Rezende’s 74-lesson fundamentals course.
- A nine-level ladder for every technique, from partners less experienced than you to more experienced ones, each split lighter, same weight and heavier.
- Land it once and it’s a hit; 3 wins across 2 sessions and it’s proven.

Why do blue belts train?
Members could pick several reasons. For blue belts, the top two were discipline (66%) and competition (59%).
These are patterns in who answered, not causes: training more often is not shown to make anyone progress faster.
What should a blue belt work on?
Blue belt is a good time to stop collecting moves and build a game: one guard you trust, one pass, and the escapes you already have made sharper against better partners.
One position at a time works well here. How to get better at BJJ sets out a weekly plan that tests one position on every kind of partner.

About the data
Training frequency and experience: self-reported answers from 3,316 adults (18 and over) who joined JitsAI between 16 October 2025 and 24 September 2026 and told us their belt at sign-up. Snapshot 25 Sep 2026. Full breakdown and a CSV on the BJJ belts page.
What we publish: totals only, groups of at least 50 people, and no share that rests on fewer than 10. Founder accounts are excluded and percentages are rounded. Most members found JitsAI through our ads, so this is a big sample but not a random one, and it leans towards people who want to improve and compete. The numbers describe patterns, not causes.
