Buy for the walls,
not the floor.

Measure one rectangular room, take out its openings, then use the coverage printed on your paint tin to plan the cans and an optional budget.

Turn your room into one clear purchase estimate.

Gross wall area is 2 × (room length + room width) × wall height. This page subtracts the door and window rectangles, multiplies the remaining area by your chosen number of coats, then divides by the coverage rate you enter from the product label. It rounds up to whole cans.

Coverage depends on the exact paint, surface, colour change, application method and preparation. This page does not select paint, verify a product's coverage, account for primer, calculate contractor labour, assess a surface, or guarantee the final quantity or finish. Check the technical information for the exact product before buying.
