Understanding Property Measurements in Thailand

When buying or selling real estate in Thailand, it’s essential to familiarize yourself with the unique land measurement system. Unlike many countries that use the metric system exclusively, Thailand measures land using rai, ngan, and square wah (talang wah). Condominiums, on the other hand, typically follow square meter measurements. Below is a concise guide to help you navigate these measurements and better understand how property is sized and priced in Thailand.

1. Key Units of Measurement

1. Square Wah (Sq. Wah or Talang Wah)
   • 1 sq. wah = 4 sq. meters
   • Often used for smaller plots or subdivided land.
2. Ngan
   • 1 Ngan = 100 sq. wah = 400 sq. meters
   • A more intermediate unit commonly seen in suburban and semi-urban land transactions.
3. Rai
   • 1 Rai = 4 Ngan = 1,600 sq. meters
   • One of the most common units for larger plots of land, especially in rural or agricultural areas.
4. Hectare
   • 1 Hectare = 6.25 Rai = 10,000 sq. meters
   • This metric measurement is not as frequently used in local real estate transactions but can be helpful when comparing international property sizes.

2. How Prices Are Calculated

• Land and Houses
  Prices for houses or land are typically quoted per rai or per square wah. This gives a clear indication of the overall land value based on traditional Thai measurements.
• Condominiums
  Condominium prices are nearly always quoted per square meter. This helps standardize costs, especially in high-rise buildings or modern developments where units vary in size but share similar amenities.

3. Why Understanding These Measurements Matters

• Accurate Budgeting: Knowing the exact size of the property helps you calculate the total cost, including taxes and transfer fees.
• Appropriate Valuation: When comparing multiple listings, uniform understanding of units ensures you’re making an apples-to-apples comparison.
• Legal Compliance: Official paperwork—especially at the Land Office—will use rai, ngan, and square wah for land transactions. Being comfortable with these units makes the process more straightforward.
