Wall project planner: paint, wallpaper and battens

Measure multiple walls and openings once, then get paint quantities, wallpaper drop estimates and decorative batten positions in one printable plan.

A 120 × 96-inch wall and a 144 × 96-inch wall total 176 square feet. A 36 × 80-inch door removes 20 square feet, leaving 156. Two coats at an entered coverage of 350 square feet per US gallon use 0.89 gallon before allowance. With 10% extra, the estimate is 0.98 gallon, rounded to one 1-gallon can.

Try the worked example, or explore our use actual board width in trim calculations.

Made for a real task

Openings are deducted for paint. Wallpaper uses full-height drops; battens use clear sections. Decorative quantities only.
