Wall Square Footage Calculator
Doors
Windows
Knowing the exact wall square footage is important for projects like painting, drywall installation, or wallpapering. A Wall Square Footage Calculator allows you to quickly calculate the total surface area of your walls by multiplying their height and width. It helps you buy the right amount of materials and thus minimize waste. It simplifies planning, saving both time and costs in your project execution.
The formula for Calculation:
The basic formula is:
Wall Square Footage = Height of the Wall (ft) × Width of the Wall (ft)
How to use it?
- With a measuring tape, measure both the height and width of your wall in feet.
- Now, applying the formula, multiply the height by the width to get the square footage of each wall.
- Check if there are any doors or windows. If yes, measure their dimensions and minus their area from the total square footage.
Real-Life Usage Examples
Painting: If you are painting a 10 ft by 15 ft wall, the total area is 150 sq. ft. Now, if there is a window that is 3 ft by 4 ft (12 sq. ft), subtract it, and you have 138 sq. ft to paint.
Wallpapering: For a wall measuring 12 ft by 8 ft, the square footage is 96 sq. ft. If there is a door that is 20 sq. ft, you will only need wallpaper for 76 sq. ft of the wall.
Important Tips to Consider
Always confirm your measurements to avoid miscalculations.
When doing detailed work, consider buying a little extra material or else you may have to run around during the final work.
Don’t forget to subtract openings like windows or doors to avoid overbuying.
The wall, which isn’t perfectly rectangular for calculation, divides it into smaller sections, calculates each area separately, and then adds them together.
