Phuket Land Conversion for Property Buyers: What You Need to Know

This guide to Phuket land conversion for property buyers explains exactly how these units work, how to convert them, and why understanding land size is essential when comparing villas, plots, or investment property.

If you’re considering buying land or wish to buy a villa in Phuket, you’ll quickly run into unfamiliar terms like rai, ngan, and square wah. These traditional Thai land measurements can be confusing, especially if you’re used to square metres or acres.

Unit Square Metres Square Wah Notes
1 Rai 1,600 m² 400 wah Common for large villa plots or developments
1 Ngan 400 m² 100 wah A quarter of a rai
1 Square Wah 4 m² – Base unit; used for smaller plots

Converting Thai Land Units into Square Metres

To make things easier, here’s the basic conversion table every property buyer in Phuket should know:

  • 1 Square Wah = 4 m²

  • 100 Square Wah = 1 Ngan = 400 m²

  • 400 Square Wah = 1 Rai = 1,600 m²

Typical Plot Sizes in Phuket

Understanding Phuket land conversion for property buyers is especially important when you see listings with local units. Common plot sizes include:

  • Townhouse or compact villa plot: 50–80 sq. wah (200–320 m²)

  • Standard villa plot: 100–200 sq. wah (400–800 m²) – common in Nai Harn, Rawai, Kamala

  • Luxury hillside or sea-view villa plot: 1 rai+ (1,600 m²+) – found in Layan, Surin, Cape Yamu

  • Development land or investment sites: Several rai – especially in Bang Tao, Cherng Talay, Thalang

Why Phuket Land Conversion Matters for Property Buyers

Getting land size right can make or break a purchase:

  • Comparing properties – what looks like a bargain may actually be much smaller.

  • Planning a villa build – pools, gardens, and multi-storey homes require space.

  • Assessing investment potential – vital for subdivisions or developments.

  • Calculating cost per unit – land is often quoted in baht per square wah.

Even if listings show square metres, title deeds (Chanote) always list rai, ngan, and wah.

Practical Example of Land Conversion

A listing shows 1 rai 2 ngan 50 wah. Using the conversion:

  • 1 rai = 1,600 m²

  • 2 ngan = 800 m²

  • 50 sq. wah = 200 m²

Total = 2,600 m²

This would be a generous plot, perfect for a luxury villa or boutique development.

Common Pitfalls with Phuket Land Conversion

Marketing materials sometimes “round up” land size. Property buyers should always:

  • Verify the Chanote title deed

  • Confirm boundaries, especially on hillside or irregular land

  • Check zoning and building allowances before purchase
