How To Calculate Carpet Area?

Method 1:

Here is the carpet area formula you can actually use

Carpet area = Built up area – Wall area



Built-up area  = 1000 sq.ft

Wall area = 300 sq.ft

∴ Carpet area = 1000 – 300 = 700 sq.ft

Method 2:

Measure all the usable area of the building and add them together.

For this, you need to measure wall to wall distance of all rooms like bedroom, bathroom, kitchen, etc and add them to get the carpet area.
