How to Tape Fingers for BJJ: 4 Methods That Stay On (2026)

Short answer: to tape fingers for BJJ, use narrow, non-stretch athletic tape on clean, dry skin. Wrap one snug ring just above the sore joint and one just below it, leaving the knuckle itself free so you can still grip. For a jammed knuckle, add an X across the side of the joint. For a sideways sprain, buddy tape it to the longer neighbor finger. If the fingertip droops, will not bend, or looks crooked, skip the tape and see a doctor.

That is the whole trick, and yet “how to tape fingers for BJJ” is one of the most repeated questions on r/bjj. The complaints are always the same: the tape slides off by the second roll, the finger turns purple, or the knuckle is wrapped so stiff that gripping a sleeve feels like holding a pencil with oven mitts. Gi grips are hard on hands, and most grapplers end up with at least one finger that sounds like bubble wrap in the morning.

This guide gives you four taping methods that actually stay on, the Finger Tape Picker table that matches each method to what your finger is doing, a fix list for tape that keeps falling off, and the red flags that mean tape is the wrong tool. One note before we start: this is common mat practice, not medical treatment.

How do you tape fingers for BJJ in under a minute?

Tear a strip of narrow rigid tape, bend the finger slightly as if gripping a sleeve, and wrap one snug ring around the segment above the sore joint and one below it. Leave the joint itself uncovered so it can still bend. Check the fingertip stays pink and warm. That two-ring method is the default for gi training.

Here is the one-minute version, step by step:

1. Wash and dry your hands. Sweat and hand lotion are the number one reason tape lets go. A quick wipe with a towel right before taping helps.
2. Get narrow tape. Many grapplers tear a standard roll of rigid athletic tape lengthwise into two thinner strips. Thin tape follows the finger instead of bunching.
3. Bend the finger slightly. Tape in the shape you grip in. Taping a perfectly straight finger is how you end up with tape that pops loose the first time you close your hand.
4. Ring above, ring below. Two or so loops around the bone segment on each side of the sore joint, snug but not tight.
5. Leave the crease free. The fold of the joint should be open so it can still bend.
6. Do the color check. Press the fingertip. If it stays white, tingles or turns bluish, the tape is too tight. Take it off and redo it.

Why do BJJ players tape their fingers at all?

BJJ players tape their fingers because gi grips load the finger joints for minutes at a time, and partners constantly rip those grips away. Tape adds a little support to joints that are already sore, limits sideways wobble after a small sprain, and protects skin from mat burn and cracked knuckles. It does not heal anything; it only supports.

In the gi, almost everything goes through your hands. You hold sleeves, collars and pant cuffs from guard, often while your partner spins, posts and yanks to break free. The joints that take the most abuse are the middle knuckles of the fingers (the ones halfway down) and the base of the thumb. Over years, many grapplers end up with thicker, stiffer finger joints, which is why you see so many black belts with tape on before warm-ups even start.

No-gi is easier on fingers because there is no fabric to hang on to, but jammed fingers still happen from posting on the mat or catching a finger on a partner. Tape is useful in both, just more common in the gi.

Which finger taping method should you use?

Pick the method based on what the finger is doing. Use two rings for a stiff or achy joint, an X wrap for a jammed middle knuckle that feels unstable sideways, buddy taping for a sprain that wobbles side to side, and a thumb anchor for a sore thumb base. Deformed or numb fingers need a doctor.

The Finger Tape Picker is our own summary of common mat practice, checked against the medical red flags from Mayo Clinic, Cleveland Clinic, HealthyChildren.org (American Academy of Pediatrics) and AAOS OrthoInfo linked below.

What your finger is doing	Method	Strips of tape	Joint left free?	Stop and see a doctor if
Achy, stiff knuckle, no swelling	Two rings	2 short strips	Yes	Pain at rest or swelling that will not go down
Jammed middle knuckle, feels loose sideways	X wrap	3 to 4 strips	Mostly	The joint looks crooked or will not fully bend or straighten
Sideways sprain, finger wants to drift	Buddy tape to a longer neighbor	2 strips	Yes	Symptoms get worse 24 to 48 hours after the injury
Sore thumb base from collar and sleeve grips	Thumb anchor	3 to 4 strips	Tip yes, base partly	Thumb is weak when pinching or swelling persists
Fingertip droops and will not straighten on its own	Do not tape for training	None	Not applicable	Right away: possible mallet finger, needs a splint
Fingertip will not bend after a grip was ripped away	Do not tape for training	None	Not applicable	Right away: possible jersey finger (torn flexor tendon)
Numb, white, cold or very swollen finger	Take tape off	None	Not applicable	Right away

The last three rows matter most. Tape is for annoying, not for broken.

How do you X-tape a jammed finger for BJJ?

Start with a ring below the jammed knuckle, run a strip diagonally across the side of the joint to the segment above, wrap a ring there, then cross back down diagonally to form an X over the joint. Finish with a ring below to lock it. The X limits sideways movement while the finger can still curl around a grip.

1. Bend the finger slightly, the way it sits when you grip a sleeve.
2. Wrap an anchor ring around the segment below the jammed joint.
3. Run the tape diagonally across the side of the joint up to the segment above it.
4. Wrap an anchor ring around that upper segment.
5. Cross back down diagonally on the opposite side to make an X over the side of the joint.
6. Finish with one more ring below and press the end flat on the back of the finger, not the palm side, so it does not peel when you grip.
7. Close your hand into a fist. If you cannot, it is too stiff. If the tip changes color, it is too tight.

Grapplers on Reddit describe this crisscross as the version that holds up best through a full class, because the diagonals keep the rings from sliding down the finger.

How do you buddy tape fingers for BJJ?

Buddy taping means taping the injured finger to the neighbor finger, ideally a longer uninjured one, with one strip above and one strip below the sore joint. Leave the joints themselves free so both fingers still bend together. Mayo Clinic and HealthyChildren.org both describe buddy taping for mild jammed fingers with full motion.

1. Pick the partner finger. HealthyChildren.org suggests a longer, uninjured neighbor, for example taping the ring finger to the middle finger.
2. Optional: put a small folded piece of gauze between the two fingers so the skin does not get soggy and raw.
3. Wrap one strip around both fingers on the segment above the sore joint.
4. Wrap a second strip around both on the segment below it.
5. Keep every joint crease free and check both fingertips stay pink.

How long? HealthyChildren.org says a minor jammed finger with very little swelling and full range of motion can be buddy taped “until it no longer hurts (1 to 2 weeks).” Cleveland Clinic says most jammed fingers heal within one to two weeks, while more severe sprains take three to six weeks or longer. Buddy taping costs you some grip strength, so expect your collar grip to feel weaker for a while. That is the point.

How do you tape a sore thumb for gi grips?

Use an anchor strip around the wrist, then loop tape from the wrist around the base of the thumb in a figure eight two or three times, and finish with a strip back over the wrist anchor. Keep the thumb tip free. This limits how far the thumb gets bent back on collar grips without stopping you from pinching.

1. Hold the thumb in a relaxed, slightly open position, like holding a cup.
2. Wrap one anchor strip loosely around the wrist.
3. From the anchor, take the tape across the back of the hand, around the base of the thumb, and back to the wrist. That is one figure eight.
4. Repeat two or three times, overlapping each pass by about half.
5. Close it off with a second strip over the wrist anchor. Check you can still touch your thumb to your pinky.

If your thumb is weak when you pinch, or the base stays swollen, get it looked at instead of taping over it. A sore thumb base after gi training is common; a thumb that cannot pinch is not.

Why does finger tape keep falling off during rolls?

Finger tape usually falls off because it went on sweaty or lotioned skin, it is too wide to follow the finger, the loose end sits on the palm side where grips peel it, or it was applied to a straight finger that then bends. Fix those four and most tape lasts the whole class without a rewrap.

This is the most common complaint in finger tape threads on r/bjj, so here is the fix list:

• Dry skin first. Wipe hands right before taping, not before warm-ups. Some grapplers tape before they start sweating for this reason.
• Thinner strips. Wide tape wrinkles at the joint and catches on the gi. Tear it in half.
• End on the back. Press the last bit of tape flat on the back of the finger, where nothing grabs it.
• Tape bent, not straight. A slight bend means the tape is already the right length when you grip.
• Rigid beats stretchy. Stretchy self-adhesive wraps are handy for buddy taping at home, but many grapplers report they loosen and slide during hard grip fighting. Rigid tape holds its shape better.
• Carry spare strips. Pre-tear a few strips and stick them to your water bottle so you can redo a finger between rounds in ten seconds.

And take the tape off after training. Leaving the same sweaty strips on all day is how you trade a sore knuckle for irritated skin.

When should you not tape a finger and see a doctor instead?

Do not tape and keep rolling if the finger looks deformed, cannot fully straighten or bend, the fingertip droops, it is numb, white or cold, or swelling and pain are severe or getting worse. Those signs can mean a fracture, dislocation or torn tendon. Mayo Clinic lists most of them as reasons to seek care.

According to Mayo Clinic, seek medical care if the finger appears deformed, you cannot straighten it, it becomes hot and inflamed with a fever, swelling and pain become significant or persistent, or the finger goes numb and turns white. Two grappling-specific injuries are worth knowing by name:

• Mallet finger. The tip droops and only straightens if you push it up with the other hand. AAOS OrthoInfo says it needs a splint worn full time for 6 to 8 weeks, and advises seeing a hand surgeon, ideally within a week of the injury. Tape is not a substitute.
• Jersey finger. The tendon that bends the fingertip tears when a gripping finger is yanked straight as the other person pulls away, which is basically a gi grip being stripped. The Merck Manual says you cannot actively bend the fingertip, the ring finger is the most commonly injured, and the treatment of choice is prompt surgical repair by a hand specialist. That is a see-someone-soon problem, not a tape problem.

For kids, Mayo Clinic adds that finger injuries need medical care because damage to the growth plate can cause long-term deformity. HealthyChildren.org also warns that compression wraps can be dangerous if they cut off circulation to the fingertip.

How do you stop wrecking your fingers in the first place?

Let go of grips that are being ripped away, grip mainly with the ring and pinky fingers, avoid sticking fingers inside sleeves and pant cuffs, and give sore fingers a few lighter days. A gi with thinner, tougher sleeves and smart training volume help too. Tape works best as a backup, not as a substitute for better grip habits.

• Open your hand. When a partner strips a grip hard, let it go and regrip. A lost grip comes back in two seconds; a torn tendon takes months.
• Squeeze with the last two fingers. Ring and pinky do the holding, thumb and index stay relaxed. It spreads the load and is a stronger grip anyway.
• Stay out of the sleeve. Fingers inside a sleeve or pant cuff get trapped when a partner spins, so keep them on the outside of the fabric in training.
• Mind the gi. Thick, stiff sleeves are harder on finger joints than lighter weaves. If you are shopping, our guide to the best BJJ gis and gi brands covers how different cuts and fabrics feel.
• Manage volume. Sore fingers are a good excuse for a no-gi day or a lighter week. Our guide on how often you should train BJJ has weekly plans by level that build in recovery.

Boxers wrap hands for a different job, protecting knuckles and wrists from impact, so do not copy a boxing wrap for grappling. If you cross-train, our how to wrap hands for boxing guide covers that side.

FAQ: Taping Fingers for BJJ

What kind of tape is best for BJJ fingers?

Narrow, rigid, non-stretch athletic tape is the usual choice because it holds its shape under grip fighting. Many grapplers tear a standard roll lengthwise into thinner strips. Stretchy self-adhesive wraps work for buddy taping at home but tend to loosen during hard rolls.

Should you tape over the knuckle or around it?

Mostly around it. Wrap rings on the bone segments above and below the sore joint and leave the joint crease free so the finger can still bend. The X wrap crosses the side of the joint, but you should still be able to make a fist.

How long should you buddy tape a jammed finger?

HealthyChildren.org says a minor jammed finger with little swelling and full range of motion can be buddy taped until it no longer hurts, usually 1 to 2 weeks. Cleveland Clinic says more severe sprains take three to six weeks or longer.

Is finger tape allowed in BJJ competitions?

Finger tape is common in BJJ competition, but each event sets its own equipment rules and a referee can inspect taping. Check the rulebook or ask the organizer before competition day instead of hoping your tape passes.

Can you train BJJ with a jammed finger?

Often yes, if it is a mild sprain with full motion and little swelling, buddy taped or ringed, and you go lighter on gi grips. If the finger looks crooked, will not fully bend or straighten, or the tip droops, stop and see a doctor first.
