Paint Coverage Calculator – m²/L by Paint Type

A reliable paint coverage takeoff follows one rule: measure twice, order once. The calculator converts your paint type and wall finish into dependable quantities using Liters = Wall Area ÷ (m² per Liter × Coats), then adds the waste margin that experienced builders apply by default. Example: 50 m² smooth wall, 2 coats of emulsion at 11 m²/L: 50 ÷ 5.5 ≈ 9 L - three 4 L cans with spare. Field tip: Darker topcoats over light walls need an extra half-liter per 10 m². The result is broken down into purchasable units - bags, sheets, rolls or truck loads - so you can order the nearest whole unit without overbuying, and every figure traces back to the formula shown above.

1. 1

   Measure the space

   Record the paint type and wall finish at the widest and longest points.

2. 2

   Enter the values

   Type the measurements into the calculator and select your units.

3. 3

   Apply the formula

   The tool computes Liters = Wall Area ÷ (m² per Liter × Coats) for your inputs instantly.

4. 4

   Add waste and order

   Review the total with a 5-10% margin and round up to whole units.

• Painting gross wall area

• Single-coat assumption

• Ignoring surface texture
