Paint Coverage Calculator | Accurate Paint Estimates

This tool will help you calculate how much paint you need for your project.

Paint Coverage Calculator

Use this calculator to estimate the amount of paint you will need to cover the walls and ceiling of a room.

How to Use:

  1. Enter the room dimensions: length, width, and height in feet.
  2. Enter the number of doors and windows in the room. These areas will be subtracted from the total paintable area.
  3. Enter the paint coverage per gallon. This value is typically found on the paint can and usually ranges between 300-400 sq ft per gallon.
  4. Click “Calculate” to see the result.

How It Calculates:

The calculator adds the area of the walls and ceiling, and then subtracts the area occupied by doors and windows to find the total paintable area. It then divides this area by the paint coverage to estimate how many gallons of paint you will need.

Limitations:

This calculator provides an estimate and may not be precise for all situations. Factors like wall texture, paint type, and number of coats can affect the actual amount of paint required.
