How Much Paint to Buy

Color Store • March 1, 2022

Planning is Important.


Once you have chosen your product and color, the next thing you need to decide is how much paint to buy. Ideally you want to have a little extra paint for touch-ups, but you don’t want to end up with too much left over paint, and you surely don’t want to run out in the middle of the project, so here are some steps that will help you determine how much you need.


The size of the room, obviously, matters.


So, get a tape measure and measure the width of each wall and its height. Multiply those figures to determine the room’s square footage. Then measure each window and door and multiply their width times their height to determine the square footage that doesn’t need panting. Finally, subtract those figures from the room’s square footage. This will give you the total square footage you will be painting.


To help you determine how much paint you need, Benjamin Moore has created an online paint calculator. Just fill in the measurements of the room you want to paint, and the calculator will show you how much paint you need for your project.


The condition and type of surface you are painting also matters. If you are painting a textured substrate you will require additional paint.


If you aren’t sure about the amount of paint you need or you have any other questions, our staff at Color Store Inc. will be glad to help you. Bring the measurements of the room you want to paint, and we will help you calculate how much paint you need and answer all your questions.
