Shin Guard Size Guide
Brand-by-brand measurements for Muay Thai, MMA and kickboxing shin guards. A guard that fits properly covers your shin and instep without shifting when you check a kick, which is the whole point of wearing them.
Coverage matters more than comfort. A shin guard should run from just below the knee to the top of your foot with no gap. Too short and you take kicks on bare bone. If you are between sizes, go up.
Shin length
Measure from just below the kneecap to the top of the ankle. This is the measurement that matters most, and the one people skip.
Height
Most brands size primarily by height, so use it as your starting point and then confirm against your shin length.
Weight
Affects calf circumference and how the straps sit. Heavier or more muscular legs often need the next size up even at the same height.

Shin guards are the one piece of kit where sizing wrong actually costs you. Shorts that are slightly tight are annoying. A shin guard that is too short leaves bare bone exposed at exactly the point where kicks land, and one that is too long rides up over your knee every time you check.
Length before anything else
Measure from just below the kneecap to the top of your foot, and make sure the guard covers that whole span. The instep pad should sit flat over the top of the foot without bunching up against your ankle.
Calf width matters too
Two people the same height can need different sizes if one has heavier legs. If your calves are on the larger side, or you plan to wear guards over ankle supports, factor that in and go up.
Sparring versus bag work
For hard sparring and competition prep, most fighters go a size up for the extra padding and coverage. For light technical work, a closer fit is fine and moves better. If you only own one pair, size for sparring.

Common questions
How should Muay Thai shin guards fit?
Snug enough that they do not rotate around your leg when you check a kick, loose enough that you can move freely. The guard should cover from just below the knee to the top of the foot with no gap at either end.
Should I size up in shin guards?
If you are between sizes, yes. Extra length gives you more coverage, and the straps take up any slack. Sizing down leaves shin exposed and there is no fixing that once the guard is on.
What's the difference between Fairtex SP5 and SP8?
They are different models with their own sizing, which is why each has its own chart above. Check the chart matching the exact model you are buying rather than assuming your size carries across.
Do shin guards break in?
Leather guards soften and mould to your leg over a few weeks, so a new pair often feels stiffer than it will long term. What will not change is the length, so do not order short expecting them to stretch.
