Thailand uses its own set of measurements of area and here is a table of those areas, with the equivalent metric measurements for comparison:
| 1 Talang Wah | 1 square Wah | 4m2 |
| 1 Ngan | 100 Talang Wah | 400m2 |
| 1 Rai | 4 Ngan | 1600m2 |
In the picture above, the red outlined plot near the road is approximately 1 Rai, and the larger outlined plot below is over 2.5 Rai. The 1 Rai plot is where the Thai House will be built.
