Find Your Fit

Fairtex Size Guide

Gear that's too loose won't protect you the way it should — gear that's too tight will hold you back mid-training. Use the charts below to find your size across gloves, shorts, headgear, and apparel.

All measurements are estimates based on average fit. If you're between sizes, factor in whether you prefer a snug or relaxed feel.

Prefer a looser fit? Size up. Want a snugger, competition-style fit? Size down. All figures below are in inches unless noted otherwise.

Gloves

Boxing gloves and grappling gloves aren't just different sizes of the same product — they're built differently. Boxing gloves fully enclose the hand for striking protection and are sized by weight (oz) and knuckle circumference. Grappling gloves leave the fingers exposed for grip and are sized by knuckle width alone.

Boxing Gloves

Sized primarily by body weight, with knuckle circumference as a secondary check.

How to measure: Wrap a tape measure around your knuckles (excluding thumb), without hand wraps on. Glove weight (oz) refers to padding, not how heavy it feels — heavier oz is for bag work/sparring, lighter oz for competition.

Glove Size	Weight (kg)	Knuckle Circumference
8 oz	36kg–51kg	14cm–16.5cm
10 oz	51kg–60kg	16.5cm–19cm
12 oz	60kg–75kg	19cm–21.6cm
14 oz	75kg–86kg	21.6cm–24cm
16 oz	86kg–120kg	21.6cm–24cm

Glove Size	Weight (lbs)	Knuckle Circumference
8 oz	79.4lb–112lb	5.51"–6.5"
10 oz	112lb–132lb	6.5"–7.48"
12 oz	132lb–165lb	7.48"–8.5"
14 oz	165lb–190lb	8.5"–9.45"
16 oz	190lb–265lb	8.5"–9.45"

Grappling Gloves (MMA)

Fingers stay open for gripping, clinching, and ground control — fit is judged purely by knuckle snugness, not padding weight.

How to measure: Measure straight across your knuckles (the widest part of your hand, excluding the thumb).

Glove Size	Knuckle Width
S	3"–3.25"
M	3.5"–3.75"
L	3.75"–4"
XL	over 4"

Fight Shorts

Shorts are sized by waist measurement. Compare your actual waist circumference to the "Approximate Waist" column — the A/B/C columns describe the garment's own dimensions for reference.

Kickboxing Shorts

Cut wide through the leg with a flared opening, sitting slightly looser and lower on the hips than athletic shorts for full range of motion through high kicks. Elastic waistband with inner drawstring.

How to measure: Measure at the point you'd actually wear them — often closer to hip level than your narrowest waist point.

Size	Waist (A)	Hip	Length (B)	Leg Opening (C)
XS	61cm–66cm	91.4cm	33cm	26.7cm
S	66cm–68.6cm	96.5cm	34.3cm	29.2cm

MMA Shorts

Cut closer to a standard athletic short — shorter in length, fitted through the waist with a drawstring/closure designed to stay put during grappling and takedowns.

How to measure: Measure your waist at your natural waistline, where you'd wear standard athletic shorts.

Size	Waist	Hip	Length
S	81.3cm	107cm	52.1cm
M	86.4cm	112cm	53.3cm
L	91.4cm	117cm	54.6cm

M	34"	44"	21"
L	36"	46"	21.5"

Headgear & More

Headgear differs from gloves and shorts in one key way: fit tolerance is built directly into the chart. A slightly loose or tight measurement still generally works, since straps typically allow a couple centimeters of adjustment.

Muay Thai Competition Headguard

Sized by head circumference, with a built-in variance range accounting for the adjustable strap most headguards include.

How to measure: Wrap a tape measure around your head, starting at the front reference point and going all the way around, keeping the tape level and snug but not tight.

Size	Head Circumference
S	50cm
M	52.1cm
L	54.1cm
XL	55.9cm

Size	Head Circumference
S	19.7"
M	20.5"
L	21.3"
XL	22"

Boxing Trunks

Cut longer than Muay Thai or MMA shorts, typically covering more of the thigh, with a traditional elastic waistband built for stand-up boxing movement.

How to measure: Measure your waist at your natural waistline, similar to MMA shorts.

Board Shorts

The loosest, most casual cut in the lineup — built for everyday or swim wear rather than fitted training, with a relaxed fit and a longer, drawstring-adjustable waist.

How to measure: Measure your natural waist, but expect these to run noticeably larger and looser than any fitted fight short at the same size.

S	81.3cm	52.1cm	107cm
