A paint calculator is a digital tool designed to help homeowners and contractors determine the volume of paint required for a specific job. It takes into account the dimensions of the room, the number of coats, and the spreading rate of the paint product used.
Using a calculator ensures you don’t over-purchase (wasting money and creating storage issues) or under-purchase (which causes color inconsistencies if batches don’t match exactly).
How to Calculate (Example):
- Measure the height and width of your walls. A room with 10ft high walls and a 40ft perimeter has 400 sq ft.
- Subtract areas for windows (~15 sq ft each) and doors (~20 sq ft each).
- Decide on coats (e.g., 2 coats). Total painting area = 400 x 2 = 800 sq ft.
- Divide by coverage (e.g., 350 sq ft/gal). 800 / 350 = 2.28 Gallons.
