About Rai

A rai (ไร่) is the standard Thai unit of land area, defined as exactly 1,600 m² (40 m × 40 m). It is used throughout Thailand for all land measurement - from rice paddies to urban plots and national parks. Thai real estate listings always quote land area in rai, ngan (400 m² = ¼ rai), and talang wah (4 m² = 1 square wah). Thailand's total rice-paddy area is reported in millions of rai. One rai equals approximately 0.395 acres or 0.16 hectares.

About Square Meters

A square meter (m²) is the SI derived unit of area, equal to the area of a square with sides of one meter. It is the standard worldwide for measuring room sizes, apartments, houses, and land plots. A king-size bed occupies about 4 m², a parking space is roughly 12-15 m², and a small apartment might be 50-60 m². This unit is fundamental in real estate, construction, architecture, and interior design globally.
