Calculate how many liters of paint you need for any room.
Estimate tiles for your floor with our tile calculator, calculate wallpaper rolls with the wallpaper calculator, or figure out concrete volume using the concrete calculator.
A 20x20 Room measures 20ft × 20ft with a 8ft ceiling. That gives a floor area of 400 sq ft and a wall area of roughly 640 sq ft.
For 2 coats of paint you need to cover around 1280 sq ft, which works out to approximately 3.66 gallons of paint (before accounting for doors and windows).
Fine-tune the estimate with our Paint Calculator.
