HOW IT WORKS

The calculator first adds only the walls you selected. Wall 1 and Wall 3 use the room length; Wall 2 and Wall 4 use the room width. The ceiling uses room length × width.

Door and window area is then deducted from the selected wall surfaces. The remaining area is multiplied by the number of coats, adjusted for waste, and divided by the coverage printed on your paint product.

Coverage varies by product and surface. Use the coverage stated on the paint can or technical data sheet for a more reliable estimate.
