**Step-1**

Calculate the length of the wall or room perimeter you want to cover, then round that number up to the closest inch. Since 27 inches is the width of a wallpaper strip, multiply this value by 27. This tells you how many wallpaper strips or “drops” you’ll need.

Take an inch-by-inch measurement of the wall’s height, eliminating baseboards and moldings. This measurement should be adjusted by 4 inches. Then, multiply it by 36, which is the average wallpaper’s vertical repetition, and round the result up to the closest whole number. It would help if you had these many repetitions for each wallpaper strip. You can calculate the length in inches of each wallpaper strip by multiplying that number by 36. Divide the number by 12 to convert it to feet.

**Step-3**

To get your total, multiply this final sum by the number of strips you determined in STEP 1. You should now know how many square feet of wallpaper you need to cover your area completely. Round it to the following whole number and divide it by 30, the number of feet in our wallpaper rolls. Voila! It would help if you got this many rolls of wallpaper.
