Use the free Accent Wall Calculator on ToolVexa to estimate the wall area and how much paint you need for one coat on an accent wall.
How to Use
Enter the wall length and height in feet, then press Calculate.
Formula in Plain Words
Wall area is length times height in square feet. Paint for one coat is the area divided by 350 square feet per gallon.
Worked Example
For a 12 ft by 9 ft wall, the area is 108 sq ft, so one coat needs about 0.31 gallons, and you should buy 1 gallon.
FAQs
Does this allow for two coats?
No. This is one coat only. For two coats, double the paint figure.
Does it subtract doors or windows?
No. Subtract their area from the wall area first if you need a tighter estimate.
Is 350 square feet per gallon exact?
No. Coverage varies by paint and wall surface, so treat it as a guide.
