Your estimate
Planning estimate only. Check the product label, pattern and installer guidance before purchasing.
Coverage varies by paint, surface and application. Use the coverage printed on the product label, and keep a little extra for touch-ups.
The estimate is yours to check.
The calculator subtracts openings, accounts for every coat and uses your paint's stated coverage before rounding up to whole cans.
Does this include ceilings?
No. Add ceiling area to the measured surface separately or make a second estimate for the ceiling.
What coverage should I enter?
Use the coverage per liter or US gallon stated by the manufacturer for the paint and surface you selected.
