Paint Calculator

Estimate how many liters or kilograms of paint you need for common jobs based on paint type, brush or roller application, and your dimensions. We add a default 20% buffer so you stay covered without wasting paint.

What do you want to paint?

Walls use standard interior paint. Door and baseboard use wood paint (high gloss). Wet room uses moisture-resistant paint.

Application

How will you apply the paint? This sets the application in Advanced options.
