Muay Thai shorts size guide logic comes down to one number, your natural waist, measured right above the hip bones. Match that number to the brand’s chart, then size up slightly for the wide leg openings and side slits the sport demands.
Forget your jeans size completely. Athletic cuts run shorter and looser through the hip, and sizing is inconsistent from brand to brand.
Key Takeaways
- Waist measurement decides Muay Thai shorts size before any brand label does.
- A fit test of ten knees, ten kicks, and a thirty second clinch reveals a wrong size faster than any mirror check.
- Snug at the waist and loose everywhere else defines correct fit, not tight all over.
- Brand size charts disagree with each other constantly, which is why custom manufacturers cut from real measurements instead.
- Gyms ordering team kit should build a full roster sizing sheet before the bulk production order goes in.
How Should Muay Thai Shorts Fit
Muay Thai shorts fit correctly when the waistband locks in through knees and clinches while the leg opening stays loose enough for a full kick. That is the whole answer.
Most fighters only discover it the hard way, usually around round three when the waistband starts sliding. How should muay thai shorts fit comes down to three checkpoints anyone can run in under a minute.
- Throw ten knee strikes. The waistband should not roll.
- Throw ten round kicks. The hem should not pull upward.
- Clinch for thirty seconds. The fabric should not bunch at the hip.
Fail any of these and the size or the cut is wrong, not the body.
What Is The Right Way To Measure For A Muay Thai Shorts Size Chart
A muay thai shorts size chart means nothing without three numbers first. Grab a soft tape and work through these in order.
- Waist. Wrap the tape just above the hip bones, level with the navel, without pulling tight.
- Hip. Measure around the fullest part of the glutes.
- Thigh. Measure the fullest point, especially if heavy squats or years of kicking pads have built up muscle there.
Match the waist number to the chart first, since that is the measurement every brand prioritizes.
SiamKick’s own chart even carries a quiet warning that their cut runs about one size smaller than a typical MMA short, the kind of detail that gets lost the moment a buyer skips straight to a number on a tag.
Are Muay Thai Shorts Supposed To Be Tight
No. Only the waistband should feel secure, while the hips and thighs stay completely free.
Are muay thai shorts supposed to be tight is the question that trips up almost every beginner who grew up wearing compression gear for other sports.
A tight fit chokes off the hip rotation that powers round kicks and teeps, two of the sport’s signature strikes.
Switch to a traditional cut with a wider leg opening the moment fabric digs into skin while the body stands still.
How Long Should Muay Thai Shorts Be
Muay Thai shorts sit several inches above the knee, shorter than almost any other training short on the market.
How long should muay thai shorts be really depends on what a fighter throws most. Three cuts dominate the racks.
- Classic Thai cut, the shortest, with the widest leg opening for high kicks.
- Slim cut, a longer inseam with less flare, built for boxing-heavy rounds.
- Retro cut, somewhere between the two, popular with fighters who split time between styles.
A shorter hem keeps fabric out of the way during clinch work. A longer hem feels more familiar to anyone coming from boxing or MMA.
Why Do Muay Thai Shorts Sizes Vary By Brand And Manufacturer
Sizes vary because no international standard governs Muay Thai shorts production.
One supplier alone stocks separate charts for six different brands, and every single one uses different waist numbers for the same letter size.
A size large from one factory can fit like a medium from the next, sometimes by two full inches at the waist.
Custom manufacturers sidestep the mess, since they cut shorts to a specification the client supplies rather than a fixed retail chart.
Torrab Sports builds every custom order from the Muay Thai shorts collection around the exact waist and hip data a gym provides, which means brand to brand guesswork never enters the conversation.
How Should A Gym Or Team Order The Right Size Run For Custom Shorts
A gym gets the size run right by collecting individual waist and hip measurements from every athlete before submitting the bulk order.
Skip this step and a single wrong assumption on a fifty-unit production run turns into fifty pairs of shorts that nobody can wear comfortably.
A handful of retail brands now run separate pages for gym owners and team orders, which proves the demand exists. None of them fold sizing guidance and the bulk order process into one page the way a coach actually needs.
Building a size run sheet takes three steps.
- List every athlete by name down one column.
- Record each athlete’s waist measurement next to their name.
- Group the roster into size bands once every measurement is in.
Muay Thai keeps growing well beyond Thailand, with one estimate placing amateur participation at around one million athletes across more than sixty countries.
Coaches can use Torrab’s request a custom quote page to submit a size run alongside artwork, so sizing data and branding decisions move through production together.
The craftsmanship process page covers how production handles size splits across one bulk order without slowing delivery down.
Frequently Asked Questions
Should you size up if you are between two waist measurements?
Usually, yes. A slightly looser waistband still locks in with the drawstring, while a tight one restricts knees and pivots the moment the pace picks up in sparring.
Do custom Muay Thai shorts run the same size as retail shorts?
Not really. Custom manufacturers cut shorts from individual measurements instead of a fixed retail chart, so a bulk order ends up sized to real waist and hip data rather than a guess off a label.
How many sizes should a gym stock when ordering team shorts?
Somewhere between four and six. Most gyms stock small through extra large for a bulk run, then add one or two custom sizes for athletes whose measurements fall outside that standard range.
