How Much Wallpaper Do I Need?

Run the Numbers

To estimate wallpaper, measure the total width of the walls you are papering and the wall height, then divide by the usable width and length of a roll, allowing extra for the pattern repeat so the design matches seam to seam. Mayflower's calculator below does that math for you: choose your wallpaper type, enter your wall width, wall height, and the pattern repeat listed on the product page, and it returns the number of double rolls to order.

Mayflower rolls are 20.5 or 27 inches wide, or 36 inches for grasscloth, and we always round up so you have enough to match the pattern. Not sure of a measurement, or working around windows, doors, or a sloped ceiling? Send your dimensions to us and we will size it with you.
