A glove that slides at the wrist, headgear that blocks your view, or shin guards that rotate after the first kick can pull focus from the work that matters. This protective gear sizing guide helps you build a kit that stays put, absorbs impact, and lets you train with confidence from warmup to the final round.
The right fit is not about chasing the tightest possible gear. It is about secure coverage, free movement, and reliable protection when training gets fast, sweaty, and demanding. Use product-specific size charts whenever they are available, then use the fit checks below before you commit to a session.
Start Your Protective Gear Sizing Guide With Measurements
Do not guess based only on your everyday shirt or shoe size. Combat-sports gear is designed around body measurements, hand circumference, weight class, and intended use. A medium in a rashguard may be right for you while medium shin guards sit too short on your leg.
Take measurements before ordering, ideally with a flexible tape measure. Measure your hand around the widest part of the knuckles, excluding the thumb. For headgear, measure around the forehead, just above the eyebrows and ears. For shin guards, measure from below the kneecap to above the ankle bone. For chest protectors or body armor, use your chest circumference and compare it with the product chart.
If you are between sizes, the right choice depends on the gear. For compression apparel, the smaller size may work if you want a close athletic fit and can move without restriction. For headgear, shin guards, and body protection, the larger size is often safer if the smaller option leaves exposed areas or strains the straps. Gear should feel secure, never painfully compressed.
Wear What You Train In
Try gear over the layers you actually use. Boxing gloves should be checked with hand wraps on. Headgear should be tested with your mouthguard in place. Shin guards should be worn over the pants, spats, or bare legs you use in class. A fit that seems perfect in a bedroom can change once you add wraps, sweat, and movement.
Boxing Gloves: Weight and Fit Both Matter
Glove sizing can confuse new fighters because ounces and hand fit solve two different problems. The ounce rating refers primarily to glove weight and padding volume. Hand compartments, wrist closures, and internal shape determine whether the glove fits your hand correctly.
For bag work and general fitness training, many adults use gloves in a middle training range that balances hand protection with speed. Sparring gloves are commonly heavier because additional padding helps protect both partners. Your coach, gym rules, body weight, and training purpose should guide the final ounce selection.
Once your hand is wrapped and inside the glove, your fingers should reach close to the end of the finger compartment without being jammed. Your knuckles should line up with the padded striking surface. A glove that is too large allows the hand to shift on impact, which can reduce wrist stability. One that is too small can curl the fingers, crowd the thumb, and become miserable during longer rounds.
Secure the wrist strap firmly enough to stabilize the joint, but not so tight that your hand tingles or turns pale. Laced gloves can offer a close, locked-in wrist feel for serious training, but they require help to put on and remove. Hook-and-loop closures are practical for independent workouts. Neither closure replaces proper wrapping and sound punching mechanics.
Headgear and Face Protection Must Stay Centered
Good headgear should sit low enough to protect the forehead without dropping into your line of sight. The cheek protection should stay centered when you turn your head, and the chin strap should secure the unit without digging into your throat.
Start by loosening all adjustable points, then set the crown or top adjustment first. This establishes where the headgear sits on your head. Adjust the back and chin closures next. Shake your head side to side, look down, throw a few light shadowboxing combinations, and check the mirror. If the face opening shifts across your eyes or the headgear rides backward, it needs a tighter adjustment or a different size.
Headgear reduces cuts and softens certain impacts, but it does not make hard contact risk-free. Avoid choosing oversized headgear simply because it feels heavily padded. Extra bulk can move during exchanges, limit vision, and make distance harder to judge. The best option balances coverage with clear sightlines and a stable fit.
Shin Guards Need Full Coverage Without Rotation
Shin guards take repeated contact in kickboxing, MMA, karate sparring, and taekwondo training. Their job is simple: cover the shin reliably and stay in place when you check kicks, pivot, or throw combinations.
The top of the shin guard should begin below the kneecap, not press into it. The lower edge should protect the bottom of the shin without piling into the ankle. If the style includes foot coverage, it should lie flat across the top of the foot and allow you to flex your toes naturally.
Fasten the straps, walk a few steps, perform a light knee raise, and throw controlled kicks in the air. If the guard twists outward or slips down immediately, it is either too loose, too large, or mismatched to your leg shape. Tightening straps can help, but overtightening may restrict circulation and still will not fix a guard that is too long.
Fit Checks for Groin, Chest, and Mouth Protection
Groin guards and chest protectors must cover the intended area without shifting into the hips, ribs, or thighs. A groin guard should sit snugly in a supported position and stay there through squats, knees, and sprawls. If it floats away from the body or pinches during a knee lift, reassess the size and support system.
Chest protection should cover the chest without riding high toward the collarbone or rolling upward during movement. Test it with pushups, straight punches, and torso rotation. In striking arts, coverage matters. In grappling-focused sessions, low-profile protection and mobility may matter more. Follow your academy and competition rules, since permitted equipment varies.
A mouthguard should seat firmly around the teeth and remain in place when your mouth is open. If you have to bite down constantly to keep it from falling, it is not fitted correctly. A properly fitted mouthguard supports breathing and communication between rounds while adding a critical layer of protection.
Apparel Sizing for Grappling and Striking
Training apparel can either support your movement or become something you fight all class. A rashguard should fit close to the body without cutting into the shoulders, neck, or underarms. Excess fabric can bunch during grappling, while an overly tight garment can restrict posture and breathing.
Fight shorts need enough room through the hips for kicks, sprawls, and guard work. Check the waistband first, then test a deep squat and a high knee raise. If the waistband folds or slides during movement, a better size or a more secure closure may be needed.
For BJJ gis, sleeve length, pant length, shoulder room, and shrinkage all matter. A gi that feels roomy before washing may settle into a more competition-ready fit afterward. Follow care instructions closely, especially if you are near the edge of your preferred size. Karate and taekwondo uniforms should allow crisp technique without sleeves or pant legs becoming distracting or unsafe.
Teen Athletes: Leave Room for Progress, Not Loose Gear
Young athletes grow quickly, so it is tempting to buy several sizes up. That approach can backfire with protective equipment. Loose gloves, headgear, and shin guards shift during contact and reduce the protection you bought them for.
Choose gear that fits safely now, with only modest adjustment room where the design allows it. Check fit every few months during growth periods. Coaches and parents should inspect closures, coverage, and overall condition before regular sparring begins.
Test Your Gear Before Hard Training
A dressing-room check is only the first step. Before sparring or intense drilling, run through a short movement test. Shadowbox, pivot, squat, sprawl, kick, and move your head through the ranges your sport demands. Your equipment should stay aligned without constant readjustment.
Watch for warning signs: numb fingers, pressure headaches, pinched skin, shifting pads, exposed shins, blocked vision, or straps that loosen after a few minutes. These are performance problems, not minor annoyances. Stop and correct the fit before intensity rises.
If you are choosing between two sizes, use the product chart, your measurements, and the type of training you do most often. A dedicated sparring setup may fit differently from a bag-work setup, and a grappler's needs may differ from a striker's. Antares Athletics sizing support can help athletes make a confident choice when measurements fall between ranges.
Your equipment should disappear into your training, leaving you free to focus on timing, technique, conditioning, and every powerful strike. Measure carefully, test your movement, and choose the fit that lets you train hard with protection you can trust.
