Thai Numbers 1–100 with Audio
Thai numbers become predictable once you know one to ten, the special word for twenty, and the rule for numbers ending in one. Hear the patterns and practise them in real price contexts.
yîi-sìp-èt · twenty-one
Thai numbers from 0 to 20
Learn these core words first. Eleven to nineteen combine สิบ (ten) with the final digit. When one follows a tens value, Thai normally uses เอ็ด rather than หนึ่ง.

The four rules that unlock 1–100
สิบ is ten. For 30–90, place the digit before it: สามสิบ is 3 × 10.
Twenty is ยี่สิบ, not สองสิบ. Numbers 21–29 begin with ยี่สิบ.
After a tens value, one is normally เอ็ด: 31 is สามสิบเอ็ด.
One hundred is หนึ่งร้อย. In conversational counting, ร้อย may be heard with context, but learn the full form first.

Using numbers with Thai prices
Add บาท (bàat) after the amount. For example, 50 baht is ห้าสิบบาท, and 99 baht is เก้าสิบเก้าบาท. In shops and markets, context may make the word บาท optional, but recognising the number itself is essential.
- Listen for the tens word สิบ; what comes before it tells you the tens value.
- Do not confuse สอง (two) with ยี่, which appears only in twenty and numbers beginning with twenty.
- Practise prices in mixed order rather than counting from one upward.
- Thai has its own digits—๐ ๑ ๒ ๓ ๔ ๕ ๖ ๗ ๘ ๙—but Arabic numerals are also widely used.
