Measuring Walls for Wallpaper: A 4-Step Guide

Are you considering wallpaper for your walls but aren't sure how to measure? Wallpaper is a fun project that can add a lot of personality and character to a room, but before you get started you need to get the measurements right to ensure you have the correct number of rolls for the desired room.

 Measure twice, hang once!

With these 4 easy steps, you'll be able to confidently order wallpaper that will perfectly fit your walls!  Taking care when measuring walls will set you up for success when hanging wallpaper, so take your time and cover all your bases to give yourself a smooth hanging experience!

Step 1: Measure your wall

First, measure the height and width of your wall in centimetres, (we suggest including windows and doors in these numbers to ensure you have sufficient wallpaper). If measuring multiple walls and they are all of an equal height, add the height and width measurements together, however, if the heights vary between walls, then each wall should be measured individually. Ensure that you add 10cm to wall height to allow for a trimming a neat edge to fit snug to the ceiling and skirting.

For our example wall the height is 2.4 metres and with width is 10 metres.

Step 2: Work out the number of drops needed.

Using with width of your walls, you can work out how many vertical drops of wallpaper will need to be hung. To do this, divide the width of your wall measurement by the width of the wallpaper. (Either 70cm or 52cm for Minibeau wallpaper.)

For our example, our wallpaper is 52cm wide, so we would divide the room width, 1000 by 52, which equals 19.2, so we would have 20 drops.

 

Step 3: Work out your pattern repeat allowance

Our wallpapers have a repeat with a straight match to give a seamless look and working out the pattern repeat allowance is a critical part of the measuring process. To calculate this allowance, head over to the product page where you can find the pattern repeat size for your chosen wallpaper, and multiply it by the number of drops you need minus one, then to calculate the number of rolls this is equal to, divide the answer by the length of the roll.

For our example our pattern repeat is 52cm. Subtract 1 from the number of drops, which is 19 and then multiply it by the 52 giving us 988cm.

988 divided by the roll length 1000 equals 0.988 so we would need just under 1 roll.

Step 4: Calculate the number of rolls needed

Now that you have all of the measurements, you can work out the total number of wallpaper rolls needed for the full project. Remember to always round up so you never run short – this could be the difference between hanging the perfect wall covering in one go, and having to re-order more supplies!
 

(Height+10cm) x Drops     + Rolls for Pattern Repeat = Total Number of Rolls

Roll Length                                                                                      

For our example room this would be:

(240 + 10) x 20       + 1 = 6 rolls

1000                         

Use the guide below to help measure your walls correctly

Measurements needed:

Wall Height + 10cm

Wall Width

Roll Length

Roll Width

Pattern Repeat

Wall width     = Number of Drops

Roll Width                                    

 

Number of drops - 1     = Rolls for Pattern Repeat

Pattern Repeat                                                

 

(Height+10cm) x Drops     + Rolls for Pattern Repeat = Total Number of Rolls

Roll Length

What to do if you haven’t ordered enough paper?
If you don't order enough paper for the job, it can be tricky to know how to proceed. The best approach is to stop hanging wallpaper when you reach the end of the wall or corner and order new paper for finishing off any remaining walls. This way, any variation in colour will not be as noticeable. However, if you’re papering only one wall and run out of paper, there is a risk that the new batch won’t match in hue and tone with the old one. Therefore, we suggest taking extra care when measuring up wallpaper so that you avoid this potential issue.
