How many rolls of wallpaper?

When purchasing your wallpaper, it's important to know from the outset how many rolls you'll need. It's recommended to choose wallpaper rolls from the same production batch to avoid color variations between batches. That's why knowing how many rolls you'll need for your project is essential from the outset. This will also help you manage your project budget.

To wallpaper a wall:

Step 1: Determine the Total Number of Strips Needed
Divide the total length of your wall by the width of one strip of wallpaper. For standard wallpaper, this is 53 cm. Example: For a 7 m wall: 7 m / 0.53 m = 13.20, rounded up to 14 strips.

Step 2: Determine the Total Length of Wallpaper Needed
Multiply the number of strips by the height of your wall, adding 10 cm for trimming (and the pattern repeat if applicable). Example: If the wall is 2.50 m high: 14 x 2.60 m = 36.4 m.

Step 3: Determine the Number of Strips per Roll
Divide the length of the roll by the height of the wall + trimming allowance. 10.05 m / 2.60 m = 3.86, rounded down to 3 strips per roll.

Step 4: Determine the Number of Rolls Needed
Divide the total number of strips by the number of strips per roll. 14 / 3 = 4.66, rounded up to 5 rolls.


Tip: Always buy at least one extra roll, especially if you're a beginner.

To wallpaper a room:

Step 1: Determine the Total Number of Strips Needed
First, calculate the perimeter of the room. Example: For a room 8 m by 5 m:
(8 + 5) x 2 = 26 m perimeter.

Then divide the perimeter by the width of a wallpaper strip (e.g., 0.53 m): 26 / 0.53 = 49.05, rounded up to 50 strips.

Step 2: Calculate the Total Length of Wallpaper Needed
Measure the wall height (e.g., 2.50 m) and add 10 cm: 50 x 2.60 m = 130 m.

Step 3: Determine the Number of Strips per Roll
10.05 m / 2.60 m = 3.86, rounded down to 3 strips per roll.

Step 4: Determine the Number of Rolls Needed
50 / 3 = 16.66, rounded up to 17 rolls.


Tip: We recommend purchasing 1–2 extra rolls if you’re a beginner.
