Paint Calculator

Enter wall size, paint coverage, and coats to estimate how many liters of paint you need.

Most walls need 2 coats for solid coverage.

Check the paint can for exact coverage rate.

Optional. Subtract windows/doors from total wall area.

Use 5?10% to account for touch-ups and losses.

How paint quantities are calculated

Wall area is calculated using wall length and height. Inputs are converted to meters for consistent area calculations.

Paint needed is the effective area (minus openings) multiplied by the number of coats, then divided by coverage rate.

A waste allowance is added to account for absorption, roller losses, and touch-ups.
