Each panel is 24” wide by 48” long (or 2’x 4’) and covers 8 square feet of wall space. To determine how much paper you’ll need, first measure the height of your wall(s) in inches that the paper will be going on and divide that by 48.” You’ll need one panel for every 48” or amount in between. For example, a 10 foot wall height will require three panels. You’ll simply need to trim the extra two feet off the bottom of the wallpaper. Repeat this with the width of your wall by measuring it and then dividing that amount by 24” to find out how many panels you’ll need. You’ll need one panel for every 24” (2’) or amount in between. A 60” (5’) wall will require three panels across to cover it and you’ll need to trim any excess. We highly recommend ordering an extra panel or two in case of any mishaps.
