1. What is Wallpaper Area Calculation?

Wallpaper area calculation determines the total square footage needed to cover walls, accounting for openings like windows and doors. This ensures you purchase the correct amount of wallpaper for your project.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Height \) — Wall height in feet
• \( Width \) — Wall width in feet
• \( Openings \) — Total area of windows, doors, and other openings in square feet

Explanation: The calculation provides the net wall area that needs to be covered with wallpaper after subtracting areas that won't be covered.

3. Importance of Accurate Measurement

Details: Accurate area calculation prevents over-purchasing or under-purchasing wallpaper, saving money and ensuring you have enough material to complete your project without interruptions.
