Calculate how much paint you need for your room walls based on dimensions and coats.

Enter Room Dimensions

How It Works

This calculator estimates paint requirements by:

  1. Wall Area: Calculates total wall square footage: 2 x (length + width) x height
  2. Coverage: Assumes standard paint coverage of 350 sq ft per gallon
  3. Coats: Multiplies coverage by number of coats selected

Tip: Buy 10-15% extra paint for touch-ups and to account for windows/doors using less area than calculated.
