Typical plots: a townhouse sits on 16 to 25 square wah, a detached house in a housing estate on 50 to 100, a pool villa on 100 to 200 (a quarter to half a rai).

Worked example

A pool villa in Phuket stands on 120 square wah with 220 m² of living space.

Land: 120 × 4 = 480 m² (5,167 sq ft)
In rai: 1 ngan 20 square wah, or 0.3 rai
The house covers less than half the plot: 220 ÷ 480 = 46% if it is on one floor.
