5 . Prepare your lengths (designs with straight or free match)
1 The number of lengths
You have to start by thinking about the number of lengths of wallpaper you will need to do your wall!
PS : a length in wallpaper jargon is just a strip of wallpaper!
2 Our friends ♥, the calculation x=2y+3²/(√45+2)
A. To find out the number of lengths needed :
Wall width / Roll width
💡 At Maison Janette all our wallpaper rolls = 53cm
Example : wall width = 5 meters
Calculation = 5 / 0,53 = 9,43.
You will therefore need 10 strips of wallpaper (always rounded upwards)
B. To find out the number of lengths in a roll :
Length of the roll / Height of the room from the plinths + 10 cm margin.
💡 At Maison Janette all our wallpaper rolls length = 10,05 m
Example : the height of our room is 2.40 meters
Calculation = 10,05 / (2,40 + 0,10) = 4,02.
So, in this case, 4 strips can be used in a roll (we always round down)
C. To find out the number of rolls needed for your entire wall :
Number of strips required for the wall / number of strips per roll
You can also use our roll calculator on our website 😉
Calculation = In our case 10 / 4 = 2,5
So we will need 3 rolls to make our entire wall (we always round up)
Conclusion, with our example to make our entire wall we need 3 rolls, and make 10 strips of 2.50m (2.40 + 0.10 H from the wall + margin of 5cm top and bottom)
PS : For non-woven wallpapers like ours, you can also cut directly on the wall, it's up to you to choose what you prefer 😊 To do this, just unroll your roll of wallpaper little by little and cut each strip at the end of your wall.
3 Start to cut !
To cut our strips, we place the roll of wallpaper on the table, unroll it and put a small mark 🗴 in pencil 🖉 to the size of the strip calculated above to be cut in our example: 2.50m!
Thanks to a ruler (spirit level type) 📏 you can cut your roll perpendicularly with your cutter.
When they're ready, roll your lengths inward!
We have therefore cut out all our lengths, we do not forget to number them, this will facilitate installation !
And here we are, our strips are ready, cut, rolled up, numbered, we can now hang them 🖔 !
Let's go to the last step : The installation of the length !
