The Phillip Jeffries Wallpaper Calculator helps you determine how many rolls of wallpaper you need for your project based on wall dimensions and roll coverage. This ensures you purchase the right amount of wallpaper for your space.
The calculator uses the following formula:
Where:
Explanation: The calculation determines total wall area and divides by roll coverage, then rounds up to the nearest whole number to ensure you have enough wallpaper.
Details: Accurate calculation prevents purchasing too much or too little wallpaper, saving money and ensuring you have enough material to complete your project without interruptions.
Tips: Measure each wall accurately in feet, count the number of walls to be covered, and check the coverage area specified on the wallpaper roll packaging. All values must be positive numbers.
Q1: Why round up to the nearest whole number?
A: We round up to ensure you have enough wallpaper to complete your project, accounting for pattern matching, waste, and potential mistakes during installation.
Q2: Should I add extra for pattern matching?
A: For patterns with large repeats, you may need to add 10-20% extra to account for pattern matching and waste during installation.
Q3: What if my walls have windows or doors?
A: For more accurate calculations, you may want to subtract the area of major openings like windows and doors from your total wall area.
Q4: Are all wallpaper rolls the same coverage?
A: No, coverage varies by product. Always check the specific coverage information provided by the manufacturer for your selected wallpaper.
Q5: Can I use this calculator for different measurement units?
A: This calculator uses feet for consistency. If your measurements are in other units, convert them to feet before using the calculator.
