    How this calculator works

    • Wall area = perimeter × height, minus doors and windows.
    • Litres = paintable area × coats ÷ coverage per litre.

    Frequently asked questions

    Two coats over a primer or putty finish is usual. Dark colours over light walls may need three.

    No. Use the same calculator with the primer's coverage and one coat to estimate primer.
