Paint coverage rates by product
Coverage is how many square metres one litre covers in one coat on a smooth, sealed wall. Manufacturers publish it per product; the figures below are the ones this calculator uses. Rough, bare or dark surfaces take more, so the tool rounds up and assumes two coats unless you change it.

A 4 m by 3 m room with 2.4 m ceilings has about 34 m² of wall. At 16 m² per litre and two coats that is 4.3 litres, so a 5 litre tin. Dulux Trade and Crown Trade tint to any NCS shade, which is how a designer colour ends up in a trade tin for up to 40% less: find the colour on DupeCoat Store.
