Wallpaper comes in double roll bolts. A bolt of wallpaper (55-60 sq ft) will contain about 40 to 50 usable sq. ft, depending on the size of the pattern repeat. Most wallpaper comes either 20½" x 33' or 27" x 27' per double roll bolt. There are two popular methods of estimating:
Method #1: Calculate the area of the walls to be covered and divide by the usable sq. ft. per bolt (the usable sq. ft. per bolt estimates can be as low as 40 sq. ft for large repeats of 20-24" to as high as 50 sq. ft for small repeats of 1-2" or random matches); deduct ¼ bolt for each door or window that fully breaks a strip of wallpaper.
Example: To paper an 8' high x 12' long wall with a 20" pattern repeat wallpaper, first calculate the square feet of wall to be covered; 8' x 12' = 96 sq. ft. Allowing 40 sq. ft. per bolt, you would need 96 sq. ft. /40 usable sq. ft per bolt = 2.4 bolts, or, rounding up, three bolts of wallpaper.
Method #2: Calculate the number and length of strips needed (allowing for pattern repeats); then figure how many bolts would be required to yield the strips needed.
Example: To paper an 8' high x 12' long wall with a 20" pattern repeat wallpaper, first calculate the number of strips needed to cover the wall. If the wallpaper comes in 20½" x 33' bolts, it would take eight strips of wallpaper 20½" wide to cover a 144" wall (12'). Next figure how many bolts would be required to yield eight strips. Each strip would have to be five pattern repeats (100") to cover the 8' high (96") wall. Since each bolt is 33' (396") long, each bolt would yield three 100" long strips. To get eight strips, then, would require three bolts of wallpaper.
These units arent compatible. square yard can be equivalent to square feet but not to feet.
18 square meters is the same as 193.75 square feet.
14' x 13' = 182 square feet.
28.4 square yards.
5 square yards.
8,435 sq. feet
Each wall is (8 x 12) = 96 square feet.Two walls = (2 x 96) = 192 square feet of wallpaper.

you will need 84 sq. yards of wallpaper
84 square yards
There's 30 yard bolts and other sizes it's 54" width and in feet it would be 30x 3 = 90 feet I can make it easy for someone you get 10 sheets out of a 30 yard Tif it's eight foot ceilings.
it depends on how big the closet is.
124 sq ft
i don't think anybody knows that anwer exept for albert Einstein
To calculate the total square yards of wallpaper needed to cover the four walls, first find the total surface area of the walls. The walls will have a total area of (2(24 \times 9) + 2(18 \times 9) = 648) square feet. Since 1 square yard is equivalent to 9 square feet, divide 648 square feet by 9 to get 72 square yards of wallpaper needed.
In order to calculate that, we also need to know the length of the room.
14.) A room is 24 feet long, 18 feet wide, and 9 feet high. How many square yards of wallpaper are needed to paper the four walls of the room?
