How to Figure out How Much Wallpaper I Need for One Wall?

Let me answer how do you work out how many rolls of wallpaper you need with an example:

• Measure the Wall's Length: Use a tape measure to find the length of the wall from one corner to the other. Note down the measurement, rounded up to the nearest whole number for a bit of extra material. For example, if the length is 119¼ inches (302.9 cm), round it up to 120 inches (304.8 cm).

• Measure the Wall's Height: Measure from the floor to the ceiling at the highest point and round up to the nearest whole number. For instance, if the height is 95½ inches (242.6 cm), round it up to 96 inches (243.8 cm).

• Convert the Measurements: Convert your measurements to feet or meters. For example, if the wall is 120 inches (304.8 cm) long, divide by 12 to get 10 feet (3.0 m).

• Calculate Surface Area: Multiply the wall's length by its height. If the length is 10 feet (3.0 m) and the height is 8 feet (2.4 m), the surface area is 80 square feet (7.2 m²).

• Adjust for Sloped Walls: If you have sloped walls, measure the base and height of the triangle, multiply them, and divide by 2. For example, a base of 10 feet (3.0 m) and a height of 5 feet (1.5 m) give a surface area of 25 square feet (2.3 m²).

So by using this formula, you can easily figure out how much wallpaper will be needed. If you cannot, seek a professional’s help.

How many wallpaper rolls for one wall?

In general, a double roll covers 57 to 61 sq ft whereas a single roll covers about 29 to 31 sq ft. but to know the exact number, you can follow a formula,

The square footage of the wall / 27 = number of wallpaper rolls

Now take for example a wall is 10 feet wide and 8 feet long

The square footage of the wall = 8*10 = 80 square feet

So the number of wallpaper rolls you will need = 80/ 27 = 2.9, almost three

This formula worked perfectly for me so I will suggest you calculate the number of wallpaper rolls required using this formula only. 

I hope this clearly answers how many rolls of wallpaper for one wall.
