Estimate Wallpaper for Any Room
Wallpaper is a popular interior design material used to enhance the beauty of walls in homes, offices, hotels, and commercial spaces. Accurately estimating wallpaper requirements helps avoid shortages and reduces unnecessary material waste. This tool calculates total wall area, subtracts openings like doors and windows, and estimates the number of wallpaper rolls required.
How Wallpaper is Calculated
The total wall area is calculated using room dimensions. Then, areas for doors and windows are subtracted. Finally, the remaining area is divided by the coverage of one wallpaper roll to estimate total rolls required.
Formula Used
Wall Area = 2 × (Length × Height) + 2 × (Width × Height)
Net Area = Wall Area − Openings Area
Rolls Needed = Net Area ÷ Coverage per Roll
