A roll of wallpaper contains 10.05 meters with a width of approx. 53 cm (Euro roll). A roll of wallpaper is therefore sufficient for approx. 5 square meters of wall space.

So two strips of standard-width wallpaper are required for each running meter of wall. So you can easily determine the required amount. In the case of a wallpaper without repeat/rapport due to the pattern, with an assumed standard room height of approx. 2.30 meters to a maximum of 2.50 meters, 4 strips come out, i.e. a good 2 meters wall width.
