How do I figure out how much paint I need for a room?

Answer 1

Measure length/width times height on all walls, do not subtract doorways or windows, and look on the paint can label.

I'm looking at a gallon can NOW that states 275 to 350 sq. ft. coverage, depending on the subsurface to be painted, I'll let you decide that.

In a 10 x 12 room for example, with 8 ft ceilings you'll have
352 sq. ft. of wall space. The reason I said don't subtract openings is to allow extra paint.

After applying thousands of gallons, I find that in a room that size, I can get one coat on with a gallon, sometimes a bit more than a single coat.

It's simple math, and knowing the suggested coverage, depending on the current finish on the walls.

Celings will be a gallon or less, and do the math again, if the ceilings are 10 ft.

Answer 2

First you need to measure the "paintable" areas. If you're using a regular latex type of paint, a gallon will cover approximately 400 square feet. Also take into consideration if you will need to do a second coat. Square footage is calculated by measuring the height and width of the paintable, multiply those 2 numbers and that is the square footage. Example: Wall is 10 feet wide and 8 feet in height,,,,,,,,,,this equals 80 sq. ft.

Good luck.
