Wallpapers have always been popular as wall coverings. Hardly anything else offers so many different options for individually designing living spaces. If you also want to beautify your walls with wallpaper, you should know exactly how much of it you need. Wallpaper is supplied in rolls which are approximately 0.53 meters wide and 10.05 meters long as standard.
In this article we will show you how to precisely calculate the number of wallpaper rolls you need before purchasing.
This formula is used to calculate the wallpaper requirement
The number of rolls of wallpaper required depends on several factors. Be aware of the total area of the room as the most important guideline. Only when you have calculated this correctly can you find out which roll length and width of wallpaper is required.
To calculate the total area for a wall, you can use a simple formula : height times width . This is important if you only want to wallpaper a single wall in the room. However, if you want it to be the entire room, you have to multiply the room height by the room circumference (added lengths of all walls).
By the way, the room height is measured from floor to ceiling and not just from the top edge of the skirting board. A cut that is too narrow should be avoided, which is why it makes sense to add around 5 centimeters to the actual height of the room.
With a standard wallpaper roll you can wallpaper around five square meters of wall space. The wallpaper strip should be long enough to cover the entire height of the room and long enough to compensate for the waste.
To do this, take the length of the wallpaper roll (for example 10.05 m) and divide it by the room height (for example 2.50 m). This results in 4.02 lanes per roll . However, keep in mind that only 5 cm of waste is allowed. In general, wallpapering creates a lot of waste, which should be taken into account when calculating the lengths of wallpaper.
How do I calculate the repeat pattern for wallpaper?
A repeat is a pattern that repeats itself over a certain length on the wallpaper strip. This is created during production using a print template or stencil, through which the pattern is repeatedly reproduced over the entire length of the wallpaper. Even though every wallpaper basically has a repeat pattern, this is not noticeable on plain wallpapers without a pattern.
It's not that difficult to calculate the number of rolls you need for one wall of wallpaper with a repeat pattern. Simply use the following instructions:
-
Divide the wall width by the roll width of the wallpaper to get the number of wallpaper strips required .
-
Length of wallpaper roll Divide by ceiling height and the repeat
Here's an example:
Room height: 2.70 m
Wall width: 3.00 m
Roll width of wallpaper: 0.53 m
Roll length: 10.05 m
Wallpaper repeat: 0.72 m
Number of wallpaper strips:
3.00 m (wall width) : 0.53 m (roll width) = 1.59 lanes (rounded up to 2 lanes )
required track length:
-
Determine the number of recurring patterns: 2.70 m (room height) : 0.72 m (repeat) = 3.75 patterns, rounded up to 4 patterns
-
Calculate track length: 4 patterns x 0.72 m (repeat) = 2.88 m
Lanes from a roll:
10.05 m: 2.88 m = 3.49, rounded down to 3 lanes
Number of roles:
10:3 = 3.33, rounded up to 4 rolls
The result is: From a roll 10 meters long with a repeat of 0.72 m, you get 2 strips with a ceiling height of 2.70 meters and a wall width of 3 meters. Accordingly , 4 rolls of wallpaper are required to wallpaper the wall.
How do you calculate the wall area?
To calculate the area of a wall, you can also use a simple formula that you probably remember from school: Area = Length x Width . To do this, first measure the length of the wall. However, there is no width in this sense, which is why it has to be replaced by the height of the room .
Wallpapering in practice: What should you pay attention to?
With the appropriate knowledge and helpful tools, you can also put strips of wallpaper on the wall as a DIY enthusiast. This process is called wallpapering and includes several steps:
If you want to save time and work when wallpapering, you should purchase non-woven wallpaper . Unlike paper wallpaper, this does not require any soaking time . The appropriate quality fleece paste can be applied directly to the wall easily, safely and without splashing. The wallpaper can then be applied from the roll to the wall without waiting and pressed on without any bubbles.
Finally, remember to trim off the excess with a ruler or spatula .
But even with wallpaper that requires “soaking time,” wallpapering can be quite easy. Please note the following rules to avoid gaps, air bubbles, bulges and wrinkles in the wallpaper:
-
Remove old wallpaper completely beforehand
-
Keep windows and doors closed while soaking and wallpapering
-
Turn off heating
-
Allow wallpaper to soften sufficiently
-
Stick wallpaper together
