you have a room with 5 × 4 m walls, you can calculate the paint amount you need by subtracting the wall area from the wall height. The paint calculator calculates the paint amount you need from the wall area as the perimeter times the wall height — 2 × (length + width) × height — optionally adds the ceiling, subtracts an allowance for each door and window, multiplies by the number of coats, adds a waste margin and divides by the paint’s coverage rate to give the litres or gallons to buy. Coverage defaults to about 10 m² per litre (350 sq ft per US gallon) but can be overridden for the specific paint. The paint calculator calculates the paint amount you need from the wall area as the perimeter times the wall height. The paint calculator calculates the paint amount you need from the wall area as the perimeter times the wall height. The paint calculator works out the paint amount you need from room dimensions and the number of coats. The paint calculator calculates the paint amount you need from room dimensions and the number of coats you need.Worked example: A room with 5 × 4 m walls has a wall area of 2 × (5 + 4) × 2.5 = 90 m². Subtract one door (about 1.8 m²) and one window (1.5 m²) for 86.7 m² net; two coats over 10 m²/L with 10% waste is 86.7 × 2 ÷ 10 × 1.10 ≈ 19.1 litres.
