How Muay Thai is scored

Key facts:

• Ten-point must. Round winner gets 10. No half points.
• Elite round length in the 22 Dec 2017 IFMA PDF: 3 x 3 minutes, one minute rest. Youth bouts are shorter in that PDF. The 2026 PDF's round table did not extract cleanly. Check the 2026 PDF before you cite a current round time.
• We will not invent a five-round IFMA fight.
• We will not invent a percentage such as "kicks are 40% of the score".
• Referee words from the 2026 PDF include YOOT for stop, YAEK for break the clinch, and CHOCK for box. A gumshield is required and must not be red or pink.

Scoring, not a specific show

What a judge is looking at, without fake weights

IFMA's criteria live in the PDF. Read them there if you are cornering an IFMA bout. In a Thai stadium, people talk about damage, kicks, and who is dictating the ring. That talk is real and it is not a published percentage. A round can be won on kicks and on ring control. We will not write "a stadium round is always 10-9 even when it is one-sided". That claim is omitted on purpose.

If you are watching RWS, the stadium site says the bouts are three rounds with a five-round championship main, and that scoring is open. Open scoring means the round scores are shown as they happen, which is a different experience from waiting for a decision. It is still not the IFMA form.

Rounds

Ruleset	Rounds we will state	Where it comes from
IFMA elite, 2017 PDF	3 x 3 minutes, 1 minute rest	22 Dec 2017 PDF
IFMA, 2026 PDF	Check the PDF	Table not cleanly extracted on 10 Oct 2026
Rajadamnern New Power and Petchyindee	5 rounds	rajadamnern.com, read 10 Oct 2026
RWS	3-round bouts, 5-round main	same site
Bangla Saturday	8 fights on the card, not a round length	stadium domain, 10 Oct 2026

Do not train for a five-round IFMA final that the PDF does not describe.

Commands and kit in the IFMA ring

YOOT stops the action. YAEK breaks the clinch. CHOCK sends you back to boxing range. Learn them if you will compete under IFMA. A gym coach may use English. The bout will not.

The gumshield rule is specific: not red, not pink. We are not giving a brand. We have no mouthguard price in the catalogue.

Clinch work is legal inside the rules and illegal as a neck crank. We will not teach a crank. The clinch guide stays with posture, inside position and knees.

If you are cornering a friend at an interclub, ask which ruleset is on the poster before you tell them they "won the kicks". An IFMA sheet and a stadium sheet can pick different winners from the same three minutes. That is not corruption. It is two sets of criteria. The poster is the one you needed to read.

FAQs

How does ten-point must scoring work in Muay Thai?

The athlete who wins the round gets 10 points. The other gets fewer. IFMA's rules PDF v3.057, fetched 10 Oct 2026, does not use fractions. That is the IFMA sheet. A Thai stadium card is a different product. We will not assign a percentage to kicks, knees or balance. A round can be won on kicks and on ring control. We are not claiming every close round is scored 10-9.

How long is a Muay Thai round?

In the IFMA PDF of 22 December 2017, elite and competitive bouts are three rounds of three minutes with one minute rest. Youth bouts in that PDF are shorter. The May 2026 PDF's round table did not extract cleanly, so check that PDF for a current time. Rajadamnern's New Power and Petchyindee fights are five rounds because the stadium says so. That is not an IFMA rule.

What do YOOT, YAEK and CHOCK mean?

In the 2026 IFMA PDF they are referee commands. YOOT stops the action. YAEK breaks the clinch. CHOCK sends the athletes back to boxing at range. A gym may use English. An IFMA bout will use the commands in the PDF. Learn them before you compete. Do not treat them as a clinch tutorial.

Why do stadium fights look different from IFMA?

Different promoter, different round count, sometimes open scoring. RWS, on Rajadamnern's site, uses three-round bouts and a five-round championship main, with open scoring. IFMA requires a Wai Kru and a gumshield that is not red or pink. Watching a Saturday show is not studying the IFMA form. Both are Muay Thai. The paperwork differs.
