Learning the numbers in Thai is one of the fastest ways to feel at home in Thailand, whether you are haggling at Chatuchak Market, reading a bus number, or telling a tuk-tuk driver your address. The good news is that the Thai counting system is remarkably logical once you learn the first ten words. In this guide you will get clear pronunciation tables, real-life examples, the actual Thai numeral symbols, and practical tips that most tutorials skip.
By the end, you will be able to count from zero to a million, read prices, and understand the small quirks that trip up beginners. Let’s dive in.
Why the Numbers in Thai Are Easier Than You Think
Thai counting is built on a base-ten system, just like English. Once you memorise the words for 1 to 10, you simply combine them to build almost every larger number. There are no complicated gender rules and very few irregular forms.
Thai is a tonal language, however, so the pitch of each word matters. Say a number with the wrong tone and a local might not understand you. That is why our tables below include tone marks to guide you.
- Rising tone (ǎ): your voice goes up, like asking a question.
- Falling tone (â): your voice drops, like a firm “no”.
- Low tone (à): a flat, low note.
- High tone (á): a sharp, high note.
The Core Numbers in Thai: 0 to 10
Start here. These eleven words are the foundation of everything else. Practise them out loud until they feel automatic, because every larger number reuses them.
| Number | Thai Script | Pronunciation | Sounds Like |
|---|---|---|---|
| 0 | ศูนย์ | sǔun | “soon” (rising) |
| 1 | หนึ่ง | nùeng | “nung” (low) |
| 2 | สอง | sɔ̌ɔng | “sawng” (rising) |
| 3 | สาม | săam | “saam” (rising) |
| 4 | สี่ | sìi | “see” (low) |
| 5 | ห้า | hâa | “haa” (falling) |
| 6 | หก | hòk | “hok” (low) |
| 7 | เจ็ด | jèt | “jet” (low) |
| 8 | แปด | bpàet | “bpaet” (low) |
| 9 | เก้า | gâo | “gao” (falling) |
| 10 | สิบ | sìp | “sip” (low) |
A quick insider tip: number 5 (ห้า, hâa) is why Thai people write “555” online to mean “hahaha”. It is the local version of “lol”.
Two Small Irregularities to Remember
Thai has only two real exceptions in the whole system, and learning them now saves confusion later:
- “One” becomes èt (เอ็ด) in the units place of numbers above ten. So 11 is sìp-èt, not sìp-nùeng.
- “Twenty” uses yîi (ยี่) instead of sɔ̌ɔng. So 20 is yîi-sìp, not sɔ̌ɔng-sìp.
Building Bigger Numbers in Thai: 11 to 100
This is where the logic shines. For the tens, you say the tens digit plus sìp (ten). For the units, you simply add the unit word afterward. It works like Lego blocks.
| Number | Thai Script | Pronunciation | How It’s Built |
|---|---|---|---|
| 11 | สิบเอ็ด | sìp-èt | ten + one (èt) |
| 12 | สิบสอง | sìp-sɔ̌ɔng | ten + two |
| 20 | ยี่สิบ | yîi-sìp | two (yîi) + ten |
| 21 | ยี่สิบเอ็ด | yîi-sìp-èt | two-ten + one |
| 30 | สามสิบ | săam-sìp | three + ten |
| 45 | สี่สิบห้า | sìi-sìp-hâa | four-ten + five |
| 99 | เก้าสิบเก้า | gâo-sìp-gâo | nine-ten + nine |
| 100 | หนึ่งร้อย | nùeng-rɔ́ɔy | one + hundred |
Notice the pattern: săam-sìp-hâa (35) is literally “three-ten-five”. Once this clicks, you can generate any number instantly without memorising it.
Large Numbers in Thai: Hundreds to Millions
Thai has dedicated words for each power of ten, which makes big numbers surprisingly clean. The only twist is mùen (10,000) and sǎen (100,000), which have no direct English equivalent word.
| Value | Thai | Pronunciation |
|---|---|---|
| 100 | ร้อย | rɔ́ɔy |
| 1,000 | พัน | phan |
| 10,000 | หมื่น | mùen |
| 100,000 | แสน | sǎen |
| 1,000,000 | ล้าน | láan |
For example, 25,500 is sɔ̌ɔng-mùen-hâa-phan-hâa-rɔ́ɔy — “two ten-thousands, five thousands, five hundreds”. You just read the number left to right, naming each place value.
Thai Numerals: Reading the Actual Symbols
Thailand uses Arabic digits (1, 2, 3) everywhere, but you will still see traditional Thai numerals on temples, official documents, and dual-price signs. Learning them is a genuine advantage many tourists overlook.
| Arabic | 0 | 1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 |
|---|---|---|---|---|---|---|---|---|---|---|
| Thai | ๐ | ๑ | ๒ | ๓ | ๔ | ๕ | ๖ | ๗ | ๘ | ๙ |
You can explore the full history of these glyphs on Wikipedia’s Thai numerals page, and hear native audio in the Wiktionary Thai number entries.
Using Numbers in Thai for Money and Shopping
The most useful skill for travellers is understanding prices. Thai currency is the baht (บาท, bàat), and vendors rarely round to zero, so knowing your tens and hundreds pays off fast.
- ฿50 → hâa-sìp bàat (five-ten baht)
- ฿120 → nùeng-rɔ́ɔy-yîi-sìp bàat
- ฿350 → săam-rɔ́ɔy-hâa-sìp bàat
Bargaining tip from experience: when a seller quotes a price, repeat the number back in Thai. It instantly signals you know the value, and prices often drop before you even counter-offer. If you want structured practice, a live tutor can drill these market phrases with you in minutes.
Practical Tips to Memorise Numbers Faster
Rote memorisation is slow. These proven techniques help the numbers stick:
- Count everyday objects in Thai — stairs, coins, notifications.
- Read prices aloud whenever you shop, even at home.
- Use the “555” trick to anchor the number five in your memory.
- Practise phone numbers, which Thai people read digit by digit.
- Book a conversation session so a native speaker can correct your tones early.

Frequently Asked Questions
How do you say the numbers in Thai from 1 to 10?
They are: nùeng (1), sɔ̌ɔng (2), săam (3), sìi (4), hâa (5), hòk (6), jèt (7), bpàet (8), gâo (9), and sìp (10). Master these first, because every larger number reuses them.
Why is 20 different in Thai?
Twenty uses the special word yîi (ยี่) instead of the usual word for two. So 20 is yîi-sìp, and 25 is yîi-sìp-hâa. It is one of only two irregularities in the whole system.
Do I need to learn Thai numeral symbols?
For daily life, Arabic digits are enough since Thailand uses them widely. However, learning the Thai symbols (๐–๙) helps you read temple signs, lottery tickets, and dual-price notices, giving you a real edge over most visitors.
What does “555” mean in Thai texting?
Because five is pronounced hâa, three fives sound like “ha-ha-ha”. So Thai speakers type “555” to mean laughter online, similar to “lol” in English.
