How to use the Paint Calculator

Painting a room is one of the most cost-effective ways to transform a space, but buying too much or too little paint can be frustrating.

  • Step 1: Measure the perimeter (total width) of all the walls you want to paint.
  • Step 2: Measure the height of the walls from floor to ceiling.
  • Step 3: Count your windows and doors. We automatically deduct them from the total area (approx 15 sq ft for windows, 21 sq ft for doors).
  • Step 4: Select the number of coats. We recommend 2 coats for the best finish and durability.

Paint Coverage Guide

Generally, one gallon of quality paint covers:

350 - 400
Square Feet

Note: Rough surfaces (like textured drywall or stucco) soak up more paint and may require 10-20% more material.
