# DO I CALCULATE THE AMOUNT OF WALLPAPER I NEED FOR A WALL?

Wallpapering requires a lot of technique to achieve the best results. The first thing to do is to prepare the wall correctly so that the whole process runs smoothly. Then the glue is applied and finally the wallpaper is installed.

One of the main recommendations is to have enough wallpaper for the installation process. To do this you need to know how much you are going to use so that you have it on hand. You will also avoid wasting the material and you will be able to keep reserves that you can use for other purposes or for when you need to repair any damage.

To start with this type of preparation, you need to know what the measurements of the roll of wallpaper are. The standard sizes are usually around 10 metres long and 53 centimetres wide.

Other sizes can be found on the market, which is why it is important to pay attention to the labelling and ask the wallpaper supplier any questions you may have.

Another thing to bear in mind is what is known as rapport. This is the measure that indicates how often the pattern or drawing is repeated and is used to make a correct fit. This prevents the design from being cut off or not following the sequence it is intended to establish.

Now that you know all the concepts, it is time to calculate how many rolls of wallpaper you will need to cover the walls of your room. Actually, there are only a few basic operations you will need to do to get this information. Of course you will also need to know the measurements of the surface you are going to cover.

## You can find out how much wallpaper you need with a few simple calculations

The first thing to do is to divide the length of the wallpaper by the length of the wall. This way you will know how many strips you can get from each roll. If there is a rapport, we must add it up to respect the pattern or motif from the second strip onwards.

Let's make an example with a wall that is 2.50 metres high and a roll of wallpaper is 10 metres long with a rapport of 70 centimetres. The first strip would be 2.50 metres long and then we would have two more strips of 3.20 metres each.

On this occasion, you will obtain 1.10 metres of wallpaper, which is not suitable for a whole strip, but it is suitable for areas with doors or windows.

In this practical case, the wall is 3 metres wide. As wallpaper usually has a width of 0.53 centimetres, you only have to divide the size of the wall by this figure to find out the number of strips you will need. For this occasion there are 6 strips. It is always recommended to buy one more unit of the total in case of any incident.

The fact of adding the rapport to the height of the wall is so that you get a strip of wallpaper with enough room to fit the pattern. This will avoid unsightly cuts in the pattern. Once you have it in place, you can cut the excess to fit the strip to the size of the wall.

Now you know how to calculate the amount of wallpaper you need. Now all you have to do is choose the design you like best.
