Wondering how much wallpaper you need? It is usually best to enable for a small extra, partly in situation a strip tears by accident but also in situation you are unable to get any more wallpaper in the same batch which would mean one strip or one roll would appear various.

All it normally takes is a little time and persistence, a metallic measuring tape, a pad and pencil and a calculator.

This is how to work it out:

one. Let’s consider a solitary blank wall very first with a wallpaper that has a basic style.

Measure the width of the wall and the top from top of the skirting to the ceiling.

e.g. 178 inches extensive and 104 inches higher.

Most wallpapers are twenty.5 inches in width (so double verify the width). Divide 178 by 20.5 (the width of the wall by the width of the wallpaper to function out how a lot of strips you need) = 8.six = nine strips of wallpaper.

The rolls are likely to be eleven yards extended, so divide 396 by 104 (the height of the wall) = 3.8. Now, if you don’t want to havehorizontal joins together your wall, so this signifies you will only get 3 complete strips for each roll.

As you require 9 strips @ 3 full strips per roll, you require 3 rolls of wallpaper.

two. Let us compute wallpaper for a solitary blank wall with a wallpaper that has a repeat layout.

Imagine the wall is a hundred and fifty five inches broad, 102 inches in height.

The wallpaper is twenty.5 inches extensive, 396 inches in a roll (which is standard) and the repeat is 19 inches.

Divide a hundred and fifty five by twenty.5 to work out the quantity of strips essential = seven.56 = 8 strips of wallpaper.

Divide the top by the repeat, 102 divided by 19 = 5.36 which means that six repeats is essential in every single strip of wallpaper so you now need to have to multiply 19 x 6 = 114 inches.

(Each and every strip of wallpaper need to be 114 inches cm and there will be twelve inches of waste on every strip.)

Divide the length of the roll by the ‘new’ top, 396 divided by 114 = 3.47 which means that there are three full strips in each and every roll. (half strips can be utilized earlier mentioned doorways and previously mentioned and beneath home windows but not in an unbroken wall).

That’s why as you want 7 strips of wallpaper and there are three total strips in every roll, you need to have 3 rolls of wallpaper.

three. To compute Papel de Parede for a complete space with doors and home windows:

Measure the top and width of the full area (incorporating jointly the widths of all 4 partitions). Even though you may possibly consider that you can subtract the width of the doorways and the home windows, you are unable to! The reason is the element of a full strip (lengthways) might be utilised beside the doorway and the waste from that can not be utilised. That’s why, I would suggest only subtracting 50 percent the width of the doors and home windows (and don’t forget you will require wallpaper above and underneath the window).

Full width of area = 483 inches

Peak = 104 inches

Repeat of wallpaper = 22 inches.

Divide the top by the repeat, 104 divided by 22 = 4.72 so five repeats are essential. 22 x five = a hundred and ten inches per strip.

Divide the total width of the place by the width of the wallpaper, 483 divided by twenty.five = 24 strips.

If there are two doors in the area, I would subtract one strip.

I would only subtract one particular strip of wallpaper for every 2 or 3 home windows in the space – far better to err on the side of caution. It is possible to work out just how considerably wallpaper is call for but you would require to know your starting up stage in the space and the specific measurements over and beneath the window

Divide 396 by 110 to operate out how numerous strips you will get out of every single roll = 3.6 which is three entire strips. Part of the remainder could be used previously mentioned doors and previously mentioned home windows. Therefore, for a space with two doorways and 3 average sized windows, I would order get 22 strips for this room (24 minus two) which is eight rolls.

If in question, double check employing a wallpaper calculator which is often accessible on websites that offer wallpaper or check with your decorator.

I hope that aids you to calculate how a lot of rolls of wallpaper you will need to have for your decorating.
