Thai Numbers: 9 Tips on How to Learn Them + Daily Life Usage

Source

Learn the written Thai digits ๐–๙ and how to say the numbers you see on price tags, dates and timetables. Start with 0–9, then use สิบ for tens and ร้อย for hundreds.

What Are Thai Numbers?

Thai numerals are written digits. For example, ๒๑ is the same number as 21. The spoken form in both cases is ยี่สิบเอ็ด (yîi sìp èt).

Commonly used in daily life in Thailand.

Read across the table to connect the number, the Thai digit and the spoken word. The pronunciation is an approximate guide. The accents mark tones.

A Brief History of Thai Numbers

Thai has its own set of ten digits. The same place values apply in both scripts, so ๑๐๐ and 100 have the same value. The Thammasat University handbook includes a beginner number list and common phrases.

Why Should You Learn Thai Numbers?

Reading the digit helps you recognise a number on a label. Saying it aloud lets you check a total, say a phone number or ask someone to repeat the price.

Reading Thai digits in context

You may encounter either script in Thailand. For example, ๒๕๐ and 250 both mean 250. The spoken number is สองร้อยห้าสิบ.

How to Learn Thai Numbers

Try these nine small exercises, then check the examples in the quick reference below.

1. Memorise the Basic Numbers (0-9)

Say 0–9 aloud, then pair each word with the written Thai digit.

2. Practice Using Flashcards

Put ๒๑ on one side of a card. Write “21” and ยี่สิบเอ็ด on the other.

3. Listen to Audio Clips

Listen for ยี่สิบ (20) and ยี่สิบเอ็ด (21). Replay them to hear the final เอ็ด.

4. Write Numbers in Thai Script

Write 30, 50 and 100 as Thai digits, then check your answers: ๓๐, ๕๐, ๑๐๐.

5. Avoid Common Mistakes

หนึ่ง is 1 on its own. For 11, 21 and 31, the last syllable is เอ็ด. Thai distance-learning number lesson gives more examples of the same pattern.

6. Engage in Interactive Practice

Write a mock price tag for 250 baht. Ask a practice partner to read it aloud as สองร้อยห้าสิบบาท.

7. Incorporate Numbers into Daily Life

Try reading 21 พฤศจิกายน as วันที่ยี่สิบเอ็ดพฤศจิกายน, meaning 21 November.

8. Join a Thai Language Group or Class

Ask a teacher to check the tone and final sound of the numbers you find hardest. If you want to practise with a teacher, see Thai Explorer’s S$45 two-hour Beginner 1 trial and confirm availability.

9. Set Goals and Track Progress

Practise one new set of numbers at a time. Start with prices under 100, then add examples in the hundreds.

When Can You Use Thai Numbers in Daily Life?

These examples show how the same spoken numbers apply to a price, a date or a string of digits.

Using Thai Numbers in Transactions

After asking a price, listen for บาท (bàat). Use the Thai price questions guide to practise asking and confirming the amount.

Thai Numbers in Dates and Time

A date can use either script. 21 พฤศจิกายน and ๒๑ พฤศจิกายน both mean 21 November.

Thai Numbers in Addresses and Phone Numbers

For a phone number, say the digits one at a time. For example, ๒๐๑ as part of a phone number can be read สอง ศูนย์ หนึ่ง. As a quantity, 201 is สองร้อยเอ็ด.

Key Differences Between Thai and Arabic Numerals

The digit shapes differ but their values are the same. Match each Thai digit to 0–9, then read the full number by place value.

Recognising both sets of digits

Learn to recognise both scripts. When the same value appears on different labels, compare the digits and check whether the figure is a date, quantity or price.

Quick Reference: Thai Numbers 1-100

Notes on Usage:

• 10 is สิบ. 20 is ยี่สิบ. For 30, say สามสิบ.
