Next calculate the square footage of every wall that will be covered, subtract areas that will bot be covered and divide by 45. That will give an estimation rolls required.

Example:
1) 20 Feet + 20 Feet + 15 Feet + 15 Feet = 70 Feet
2) 70 Feet X 9 Feet Height = 630 Sqft
3) Less:
a. Windows 3 X {( 4 X 5 ) One Window} = 60 Sqft
b. Door {1 X ( 3 X 7 ) One Door} = 21 Sqft
c. Total = 81 Sqft
4) 630 Sqft – 81 Sqft = 549 Sqft
5) 549 Sqft / 45 Sqft Per Roll = 12.2
6) 12.2 = 13 Rolls of Wallcoverings
7) Border ( 70 Feet – 12 Feet – 3 Feet )
(Refer to Border Calculation) = 55 Feet / 15 = 3.6 = 4 Rolls
Additional Information
a. To calculate Top and Bottom (Top X 0.7) (Bottom X 0.3)
i. 13 rolls = 13 X 0.7 = 9.1 = 9 Rolls Top
ii. 13 rolls = 13 X 0.3 = 3.9 = 4 Rolls Bottom
