# How to Determine How Much Paint You’ll Need

Are you about to embark on painting project? Check out this handy guideline to calculate how much paint you’ll need from the helpful staff at Dulux in Bedford.

1. Have on hand a measuring tape, a pen, paper, and a calculator.

2. Measure the height and width of all surfaces you need to paint. Multiply the height by the width to determine the square footage (or width by length on a ceiling).

3. Measure the height and width of all surfaces you do not want to paint. An easy estimate is 20 sq ft for each door and 15 sq ft for each average sized window. You will also need to include cabinets, built-ins, skylights, radiators and trim if not being painted. Multiply the height and width of surfaces not being painted, and add them up for total square footage.

4. Subtract the square footage you will not be painting from the square footage you will paint to get the total square footage of coverage needed.

5. Multiply the square footage needed by the number of coats you wish to apply. Then divide that number by 400 to find out the gallons of paint needed. If there is a remainder of less than half a gallon, add on a couple of quarts. If there is a remainder larger than half a gallon, then buy an extra gallon. Note: there are 4 quarts in a gallon.

Happy painting!
