FAQ

What is typical paint coverage?

Latex paint typically covers 10-12 m²/L per coat. Textured paints cover about 6-8 m²/L. Always check the paint can label for the manufacturer's specified coverage.

How many coats do I need?

Two coats are generally recommended. Light colors over dark may need three coats. With a primer system: one primer coat plus two topcoats. This tool supports 1-3 coats.

How are doors and windows handled?

Enter the total area of doors and windows. The calculator automatically subtracts this from the wall paintable area, since those surfaces typically don't need painting.

Is my data safe?

Absolutely. This tool runs entirely in your browser. All calculations are performed locally — no data is uploaded to any server.
