How Much Wallpaper Do I Need?
Step 1: Determine the square footage of each wall to be covered by multiplying the ceiling height by the wall width.
Step 2: Add the square feet of all walls together to get the total square footage.
Sq. ft. in wall 1 +
Sq. ft. in wall 2 +
Sq. ft. in wall 3 +
Sq. ft. in wall 4 =
Total number of sq.ft. to be covered.
Step 3: Divide the total sq. ft. by 25 to determine how many single rolls you will need. The number 25 allows for a large repeat pattern to ensure you will have plenty of wallpaper for your projects.
Step 4: All wallpaper is sold in double rolls. So after you get your number in step 3 divide it by two to figure how many double rolls you will need.
Need a Border?
Most rolls of borders have 5 yards or 15 feet per roll. To calculate how much border you will need follow this calculation:
Width in wall 1 +
Width in wall 2 +
Width in wall 3 +
Width in wall 4 =
Total width for all 4 walls.
Take the total width and divide by 15 feet = number of rolls of border you need.
