How it's calculated
Each step, in the order Jobmath runs it.
| Step | Formula |
|---|---|
| Room area | Length × width |
| With waste | Area × (1 + waste %) |
| Boxes | Area with waste ÷ square feet per box, rounded up |
Rooms that are not rectangles
Split the room into rectangles and run the calculator for each.
| Shape | How to measure |
|---|---|
| L-shaped room | Split into two rectangles, run each, add the boxes |
| Closet or hallway | Measure separately and add |
| Bay window or angled wall | Measure to the widest point |
