Figure gallons for house walls using coverage from your paint can.
How it works
Perimeter × height less openings, × coats, ÷ coverage per gallon.
Before you order
- Rough or bare siding soaks up more, so lower the coverage figure.
- Mix cans together in a bucket so color stays even.
- Paint in shade when you can, since hot walls dry too fast.
Common questions

Often around 350 square feet, but check your can.
