With 8 ft ceilings the walls total about 448 square feet before doors and windows. Two coats at about 350 sq ft per gallon is roughly 3 gallons. The ceiling adds another 192 square feet.
How to calculate square footage
For a rectangle, multiply length by width in feet. A 12 × 10 ft room is 120 square feet. For a room that is not a plain rectangle, break it into rectangles, triangles or circles, find each area, then add them up. Subtract anything you are leaving out, such as a closet or fireplace.
Formulas for each shape
- Rectangle: length × width
- Triangle: base × height ÷ 2
- Circle: π × (diameter ÷ 2)²
- Trapezoid: (base 1 + base 2) ÷ 2 × height
What to do with the number
Square footage is the starting point for flooring, paint, sod and cost estimates. Once you have it, size the job with the tile calculator, the concrete calculator or the gravel calculator.
