The simple answer is three. For an average-sized room, you will get three drops of wallpaper per roll with some paper left over for finishing around windows and doors. For rooms with lower ceilings, you may get four drops per roll and for those with extra high ceilings, you may only just get three drops.
The average width and length of a wallpaper roll
Generally speaking, most rolls have a width of between 37-42 inches, with lengths ranging from 25-30 feet. Some wide-width extremely textured wallpaper can be as wide as 60 inches or more, while narrower rolls tend to be used for more delicate patterns.
A single roll of wallpaper is 27 inches wide by 5 yards long (68.58 cm x 4.57 meters) and covers 30 square feet (waste and pattern matching usually takes this down to about 27 usable square feet per roll).

Condition of existing wallpaper: Assess the condition of the current wallpaper. If it's in good shape—adhered well to the wall, no peeling edges or bubbles—it might be suitable for wallpapering over.

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.
How much does one roll of wallpaper do? This obviously depends on the size of the roll and the room. However, a standard sized wallpaper roll is usually 50cm or 52cm wide and 10m long, which equates to 5 or 5.2 square metres. This is roughly three to four vertical drops in an average height room.

Remember, wallpaper only comes in double rolls, even though they price out the cost in single roll quantities. You can count on double rolls to always be twice as long as single rolls.
Vinyl: This is the most common type of wallpaper because it is easy to hang and remove, is the best option for damp areas, and often comes pre-pasted. Non-Woven: This type of wallpaper is not vinyl-coated and is resistant to moisture and water, making it ideal for the bathroom.
The most accurate way to calculate wallpaper quantities is by figuring out how many floor-to-ceiling strips you'll need in the room, and then determining the number of usable strips on each roll of wallpaper you plan to purchase.
