This tool helps you calculate how much wallpaper you need for your room.
Wallpaper Estimator
This calculator will help you estimate the number of rolls of wallpaper needed for your room.
How to use:
- Enter the length, width, and height of the room in feet.
- Enter the number of doors and windows in the room.
- The average door and window areas are preset but can be adjusted if needed.
- Enter the coverage area per roll of wallpaper.
- Click “Calculate” to get the result.
Calculation Explanation:
The calculator first determines the total wall area by summing up the areas of each wall in the room. Then it subtracts the total area occupied by doors and windows to get the usable wall area. Finally, it calculates the number of wallpaper rolls needed by dividing the usable wall area by the coverage area of each roll and rounding up to the next whole number.
Limitations:
This tool provides an estimate based on standard room shapes and sizes. Irregular wall shapes, alcoves, and other architectural features may require additional calculations. It also assumes that all rolls of wallpaper are the same size and coverage.
Use Cases for This Calculator
Calculating Wallpaper Rolls Needed
You can accurately determine the number of wallpaper rolls needed for your room by entering the dimensions of the walls and the pattern repeat of the wallpaper. The calculator will provide you with the exact quantity required, ensuring you buy just the right amount for your project.
Estimating Total Square Footage
You can quickly get an estimate of the total square footage of the walls you plan to wallpaper by measuring the width and height of each wall and inputting these values into the calculator. This feature helps you purchase the correct amount of wallpaper without excess wastage.
Handling Multiple Wall Measurements
If you have multiple walls to wallpaper with varying dimensions, you can input each wall’s measurements separately into the calculator. This capability ensures accurate calculations for each wall, making your wallpapering project hassle-free and efficient.
Adjusting for Doors and Windows
The calculator allows you to account for doors and windows in your room by entering their dimensions. By subtracting these areas from the total wall area, you get a more precise wallpaper requirement, saving you from purchasing excess materials.
Considering Different Wallpaper Roll Sizes
You can select from various wallpaper roll sizes in the calculator to match the specific product you intend to use. This customization ensures the calculations align with the rolls available for purchase, making your shopping experience seamless.
Factor in Pattern Matching
If your wallpaper has a pattern that requires matching across adjacent strips, the calculator can factor in this pattern repeat. By specifying the pattern match, you ensure the correct alignment of the design, resulting in a professional and polished finish.
Calculating Waste Percentage
