Muay Thai shorts size guide by brand (Fairtex, Yokkao, Primo, Venum, Twins)
Size Muay Thai shorts on the chart for that brand and model: Fairtex's chart puts an M at about a 28-inch waist, Primo's Stadium chart puts an M at 26–29 inches, and Yokkao measures M as 36–38 cm across the waistband laid flat (each brand's own chart, read 1 Nov 2026).
Sizes copied as printed from each brand's own chart, linked. No conversions of our own. Muay Thai Atlas never takes deposits or payments.
How to measure
- Waist: most brands list the waistband laid flat, edge to edge (Fairtex "A", Yokkao "A") or a waist range (Primo). Fairtex also prints an "approximate waist".
- Length: top of the waistband to the hem, down the side (Primo "Length", Fairtex "B", Yokkao "B").
- Leg opening: across one leg (Primo "Bottom", Fairtex "C", Yokkao "C").
- Measure a pair of shorts you like, flat on a table, and match the brand's own numbers. Charts differ by brand, so never carry a size across brands.
Fairtex

Primo

| Small | 12.0 | 24–28 | 10.0 |
| Medium | 12.5 | 26–29 | 10.5 |

Venum
Not shown. On 1 Nov 2026 Venum's old size guide link for men's Muay Thai shorts opened a product list instead, and a Venum Muay Thai shorts product page we opened in a browser showed no size table we could read. Retailer copies exist but are not the brand's chart, so we don't use them. Look for the chart on the product you buy: Venum Muay Thai shorts.
Twins Special
Not shown. We found no shorts size chart on twinsspecial.com on 1 Nov 2026 (the site points buyers to its contact page). Ask the seller for the brand's chart.
Other tips
- Between two sizes on a brand's chart: measure a pair you own and match length and leg as well as waist.
- Women's cuts: women's Muay Thai shorts.
- For a first class you don't need branded shorts; gym shorts you can kick in are fine (shorts guide).
Who holds your money?

Questions
What size Muay Thai shorts should I get?
Use the chart for that brand and model. On Fairtex's chart an M has an approximate 28-inch waist; on Primo's Stadium chart an M is 26–29 inches; on Yokkao's an M is 36–38 cm across the flat waistband.
Do Thai shorts run small?
We haven't measured samples, so we don't say. Compare the brand's numbers with a pair you own.
Are Fairtex and Yokkao sizes the same?
No. Fairtex prints inches and an approximate waist; Yokkao prints the flat waistband width in cm. Use each chart on its own.
Where is Venum's size chart?
Venum's old size guide link now opens a product list, and the product page we opened on 1 Nov 2026 showed no chart we could read. We'll copy it here once we can read it on Venum's own site.
Can I buy shorts on Muay Thai Atlas?
No. Atlas doesn't stock or ship gear. Muay Thai Atlas never takes deposits or payments. Any retailer link added later will say "Affiliate link".
