Muay Thai Shorts Sizing: A Western Fit Guide

If you’ve trained Muay Thai for any length of time, you’ve probably lived this: you order a pair of shorts from a respected Thai brand, size up to be safe, and the “2XL” still ends up fitting someone half your size. It’s not you. It’s the sizing.

Why Muay Thai shorts run small

The gold-standard Muay Thai brands — the names you already know — are made in Thailand and sized for Thai and broader Asian frames. That’s exactly right for their core market. But the sizing baseline is simply smaller, so the conversion is brutal for Western bodies.

• A Thai “XL” often lands closer to a European medium or large.
• Waistbands and rises are cut shorter, so taller athletes get a low, tight sit.
• Size runs frequently stop before they reach genuinely large Western frames.

How to measure for the right size

Skip the guesswork and measure before you buy:

• Waist: measure around where the shorts will actually sit — high, just above the hip bone, not at your jeans line.
• Hips: measure around the widest point so the shorts clear your thighs through a kick.
• Compare those numbers to the product’s size chart in centimetres, not to another brand’s label.

Muay Thai shorts are meant to sit high with a wide, flared leg — that’s what gives your knees and kicks room to travel. A good fit looks short and open, not baggy.

What a true Western fit looks like

Our shorts keep everything that makes Muay Thai shorts work — the high cut, the wide leg, the freedom to throw knees and teeps without restriction — and put it on a Western size run. A large fits a large. The size range keeps going for taller and bigger athletes. You buy the size you are.

No conversion charts. No ordering three sizes up and hoping. Just shorts that fit the body doing the training.
