Paint & walls calculators

3 free calculators · instant · nothing you enter is uploaded

Paint is the cheapest way to change a room and the easiest thing to run out of halfway along a wall, where a second tin from a different batch may not match. These calculators work out the paintable wall area first, deduct doors and windows, apply the coverage printed on the tin and the number of coats you actually intend to use, then convert the answer into litres or gallons. The same group covers wallpaper rolls, adhesive and drywall sheets, so a whole wall-and-ceiling job can be planned from one page.
