How To
How to Measure a Room
- 1Measure the longest wall for length, then the adjoining wall for width, in feet. Round up to the nearest inch.
- 2Multiply length × width to get the room's square footage. A 12 × 15 room is 180 sq ft.
- 3Add each closet or nook as its own row, then add them together for the total room area.
- 4Apply the waste factor for your layout so you have extras for cuts and future repairs.
