How to calculate the quantity of wallpaper rolls:
Let us assume that the wall size is 14 feet https://paperyourwalls.com/wp-admin/edit.php?post_type=product(width) by 10 feet (height). The total area becomes 14 X 10 = 140 square feet. One wallpaper roll covers 50 square feet. So, the number of rolls required to cover the wall is 140 sq. feet / 50 sq. feet which is 2.8 means 3 rolls.
So basically, we take the area of the wall and divide it by 50 (the area that one wallpaper roll covers)
