There's a special frustration reserved for white belts: you tie your belt, bow onto the mats, and by the second round it's hanging open like a bathrobe. A properly tied BJJ belt should survive an entire class. Here's the classic method, step by step, plus the tricks that keep it locked down during hard rolls.
The Standard BJJ Belt Tie: Step by Step
Step 1: Find the center
Hold the belt out in front of you and find its midpoint. Place the middle of the belt against your stomach, just below your navel, with equal length hanging on each side.
Step 2: Wrap it around twice
Bring both ends behind your back, cross them over, and bring them back to the front. The belt should wrap snugly around your waist two full times. Keep it flat — twisted belt digs in and loosens faster.
Step 3: Tuck the top layer
Take the end that's on top and tuck it up and under both layers of the belt at your waist, pulling it through toward your chest. This anchors everything. Pull both ends to snug the wrap tight around your waist.
Step 4: Tie the knot
Cross the left end over the right to form an X, then thread the top end through the loop and pull tight — a simple square knot. The knot should sit centered and flat, with both tails hanging roughly equal, ending around mid-thigh.
How to Keep Your Belt Tied During Rolls
- Wrap it snug, not loose. Most belts come undone because the waist wraps were loose to begin with. It should feel firm before you even tie the knot.
- Keep the belt flat. Twists and folds create slack that works loose as you move. Smooth it out on every wrap.
- Tie it low on the waist. A belt tied up near the ribs migrates; one sitting on the hips stays put.
- Retie between rounds. Even a perfect knot loosens over time. A quick retie during water breaks beats rolling with a flapping belt.
- Use a stiff belt. A quality pearl weave belt holds a knot far better than a soft, worn-out one. If your belt is limp and faded, it's working against you.
What If Your Belt Is Too Long or Too Short?
Belt length matters as much as technique. When tied, the tails should end around mid-thigh with both ends roughly even. If the tails hang past your knees, the belt is too long — it'll come undone constantly and get in the way. If they barely reach your hips, it's too short to wrap twice and knot securely. As a rough guide, your belt size generally tracks your gi size (an A2 gi pairs with an A2 belt), but when between sizes, most grapplers prefer going slightly longer rather than shorter.
BJJ Belt Care
Wash your belt regularly — yes, really. The old tradition of never washing a belt is a myth that just breeds bacteria; modern gyms expect clean gear. Wash cold with your gi and hang dry to prevent shrinkage and keep the color from fading. A stiff, clean belt ties tighter and lasts years longer than a neglected one.

How to Tie a BJJ Belt FAQ
Which side should the BJJ belt knot be on?
Centered is standard. Some grapplers tie slightly to one side out of habit — either is fine as long as it's secure.
How long should the belt tails be?
Roughly mid-thigh, with both ends even. Much longer and the belt is too big; much shorter and it's too small.
Why does my BJJ belt keep coming undone?
Usually loose waist wraps, a twisted belt, or a soft worn-out belt that can't hold a knot. Wrap snug, keep it flat, and replace dead belts.
Should you wash your BJJ belt?
Yes. Wash it cold with your gi and hang dry. The "never wash your belt" idea is an old myth — hygiene matters more than superstition.
