Master Thai Numbers: How to count in Thai

Introduction: The Rhythm of Numbers in Thai Life

In Thailand, numbers are more than digits - they're woven into markets, temples, and daily conversations. From haggling at a street stall to sharing your age, mastering Thai numbers unlocks authentic interactions. This guide simplifies counting, highlights cultural quirks, and equips you for real-life scenarios. Let’s count like a local!

1. Thai Numbers 0-10: The Foundation

While Arabic numerals (0-9) dominate daily life, Thai script numbers (๐-๙) appear in formal contexts. Here’s how to pronounce them:

NumberThai ScriptThai WordPronunciation
0ศูนย์sǔun
1หนึ่งnùeng
2สองsǒng
3สามsǎam
4สี่sìi
5ห้าhâa
6หกhòk
7เจ็ดjèt
8แปดbpàet
9เก้าgâo
10๑๐สิบsìp

Pro Tip: Thais often drop “หนึ่ง” (nùeng) for “1” in multi-digit numbers. E.g., 100 = róoi (ร้อย), from  "nùeng-róoi (หนึ่งร้อย)".

2. Counting 11-1,000,000: Patterns & Pitfalls


11-20: The Teens

  • 11: สิบเอ็ด (sìp-èt) – Literally “10 + 1” (not "nùeng หนึ่ง").
  • 12-19: สิบ + digit. E.g., 15 = sìp-hâa สิบห้า.
  • 20: ยี่สิบ (yîi-sìp) – Unique! Not "sǒng-sìp สองสิบ".

Tens, Hundreds, & Beyond

NumberThai WordPronunciation
100ร้อยrói
1,000พันphan
10,000หมื่นmùen
100,000แสนsǎen
1,000,000ล้านláan

Pattern: Combine digits left to right.

  • 256: sǒng-rói-hâa-sìp-hòk (สองร้อยห้าสิบหก).
  • 3,500: sǎam-phan-hâa-rói (สามพันห้าร้อย).

Watch Out:

  • 21: yîi-sìp-èt (ยี่สิบเอ็ด) – Not sǒng-sìp-nùeng.


3. Cultural Nuances: Lucky Numbers & Daily Life

  • Lucky 9: เก้า (gâo) symbolizes progress. Popular in weddings and business deals.
  • Unlucky 6: หก (hòk) means “to spill”
  • Bargaining: Use numbers confidently! E.g., tâo-rài khá/kháp? (เท่าไหร่คะ/ครับ) = “How much?”


4. Real-Life Scenarios


🛍️ Shopping

  • Seller: hâa-róoi bàat (ห้าร้อยบาท) = “500 baht.”
  • You (bargaining): lót dâi mǎi khá/kháp? (ลดได้ไหมคะ/ครับ) = “Can you lower the price?”

📅 Dates & Time

  • Date: wan-níi wan-tîi sìp-èt (วันนี้วันที่สิบเอ็ด) = “Today is the 11th.”
  • Time: sǒng-thûm (สองทุ่ม) = “8 PM” 

📱 Phone Numbers

  • Example: 089-123-4567 = sǔun-bpàet-gâo, nùeng-sǒng-sǎam, sìi-hâa-hòk-jèt.

5. Common Mistakes & Fixes

  • Mixing Tones: ห้า (hâa = 5) vs. หก (hòk = 6). Practice tones with apps like ThaiTone.



6. FAQs

Q: Why is 20 yîi-sìp instead of sǒng-sìp?

A: Historical roots! Old Thai used yîi ยี่ for “two” in specific contexts.

Q: How do Thais write numbers formally?

A: Thai script (๐-๙) in official documents; Arabic elsewhere.

Q: Is zero (sǔun) ever omitted?

A: No! In phone numbers: 085 → sǔun-bpàet-hâa

Thai numbers are your gateway to smoother travels, smarter shopping, and deeper connections. Start small (0-10), embrace patterns, and practice daily.
