Tying a BJJ Belt: Learn One Method and Check the Fit

A BJJ belt should hold your jacket closed while letting you move and breathe comfortably. Start with one method your coach can check, then practice that same sequence slowly. You do not need a different knot every time it comes loose.

Ask the instructor to demonstrate the whole tie, including the final crossing, then watch you repeat it. Different finishing knots can look similar in a written description. Use this guide alongside that demonstration to check the finished fit.

Set up the jacket and belt

Close the jacket as your instructor demonstrates. Left lapel over right is a common convention; it is not presented here as a universal competition requirement. Smooth the jacket before wrapping so you are not tightening the belt over bunched fabric.

Find the belt's middle by bringing its ends together. Put that midpoint against the front of your waist. Keep the fabric flat as you work.

Learn the sequence without guessing the last crossing

During the demonstration, ask the instructor to pause at three places:

1. The wrap: Where does the belt's middle go, how do the wraps lie around the waist, and when should you even up the tails?
2. The tuck: Which end moves, which waist layers does it pass under, and where does it come out?
3. The finish: Which end crosses next, which opening does it pass through, and how should the finished knot sit?

Describe the ends using your own left and right while you practice. Someone facing you has the opposite view. If you lose track, undo that part and ask to see it again rather than pulling an uncertain crossing tighter.

Repeat the demonstrated tie once with the instructor watching. Then check that the jacket stays closed, the wraps are comfortable, and you can bend, sit, and breathe normally. If something pinches or slides, show that specific problem before joining partner practice.

For another first-party instructional example, Hayabusa's belt-tying guide describes several methods. It is a manufacturer's resource, not an academy policy or product recommendation. Use it as a reminder only when you can identify the same method you were shown.

Find the part that is coming loose

The wraps slide while the knot stays tied. Check the fabric around your waist before changing the finishing knot. Pulling only the tails can leave slack behind you.

The knot opens repeatedly. Ask the coach to watch the last crossing. A square knot and a granny knot differ in how the crossings relate; the word “double” alone does not tell you that relationship.

The tails are very uneven. Reset the wrap length before the tuck. If a balanced tie still leaves unsuitable tails, check that belt model's sizing information. A belt size is not guaranteed to match a gi size.

The jacket still will not close comfortably. Resolve the garment fit as well as the knot. The gi try-on checklist covers that separate question.

Check class requirements and event requirements separately

For its events, the IBJJF uniform page specifies two waist wraps, a double knot that holds the gi top closed, and tails of 20 to 30 cm after tying. These are IBJJF requirements, not evidence that every class or tournament uses the same specifications.

Keep the belt clean and dry according to its care instructions; the gear-care routine covers preparation between classes. For rank questions, use the separate belts and stripes guide.

Before your next gi class, ask the coach to watch one complete tie. That gives you a specific sequence to practice at home.
