How much paint does a room actually need? Put in the size of the room, take off the doors and windows, choose how many coats you want, and this works out the litres — then rounds up to whole tins with a little in hand. It all happens in your browser; nothing is sent or stored.
The figure is a planning estimate, not a promise. Coverage varies with the paint, the colour you’re covering and how the surface has been prepared, so always check the coverage printed on the tin before you buy. A fresh, porous or strongly coloured wall can drink far more on the first coat.
