Have you felt overwhelmed at the idea of using wallpaper because you simply didn't know how much to use? It doesn't need to be like that! In just a few seconds you can figure out exactly how much wallpaper you need to create, remodel or just revamp that beautiful space of yours. Find in this article all you need to know about measuring your mural wallpaper or pattern wallpaper to fit your amazing walls.

One of the things that first come to mind when deciding to buy wallpaper is figuring out how much wallpaper to use, whether you're using Mural Wallpaper or Pattern Wallpaper. Read below for a simple and efficient method to calculate your wallpaper.

How to get the right amount of wallpaper?

The very first thing you need to do is measure the surface area of yours walls. The surface area of your wall is your wall height times your wall width. Then, you need have a look at the kind of wallpaper you will use. At Forest Homes we have two kinds: Mural Wallpaper or Pattern Wallpaper (Double Roll Wallpaper). Let's have a look at the differences between those two.

What is Mural wallpaper?

Mural Wallpapers, especially those inspired in nature, are a great way to expose yourself to stunning imagery and create unique interior spaces. Instead of being a repeated pattern, mural wallpaper is a large, scalable image. Mural wallpaper is generally sold by the square meter, and the package could come in one or several rolls.

How much Mural Wallpaper do you need?

With your wall measures, what you need to do is calculate the wall surface area. If you have several walls you can add up the surface areas of each of the walls together. The total area will be equal to the order units. Let's say for example,  your wall measures 3 m (9.8 ft) width and 2.4 m (7.9 ft) height. Include a few 5 cm (2 in) for errors in measuring. To get the area, multiply 3.05 m (10 ft) width times 2.45 m (8ft) height and that is equal to 7.47 sq. m. (80 sq. ft) Round up and you need 8 sq. m or 8 units of Mural Wallpaper (80 sq. ft).

What is Pattern Wallpaper?

A pattern wallpaper, as the name explains itself, is a wallpaper where the same pattern is repeated across the strips of wallpaper. At Forest Homes, we sell pattern wallpaper by the double rolls. Double rolls will cover approximately 5.2 sq.m (56 square feet). They come by length of 10 m (32.8 ft) and width: 53 cm (1.73 ft).

The process is similar to the previous mural wallpaper in that you should calculate your walls' surface area and combining them all together, you can use the following estimator:

Total Square Footage to Cover # of Double rolls Required
up to 4.5 sq.m (50 sq ft) 1 double rolls
4.5 to 9.3 sq.m (50 to 100 sq ft) 2 double rolls
9.4 to 13.9 sq.m (101 to 150 sq ft) 3 double rolls
14 to 18.6 sq.m (151 to 200 sq ft) 4 double rolls
18.7 to 23.2 sq.m (201 to 250 sq ft) 5 double rolls
23.3 to 27.9 sq.m (251 to 300 sq ft) 6 double rolls
28 to 32.5 sq.m (301 to 350 sq ft) 7 double rolls
32.6 to 37.2 sq.m (351 to 400 sq ft) 8 double rolls
37.3 to 41.8 sq.m (401 to 450 sq ft) 9 double rolls
41.9 to 46.5 sq.m (451 to 500 sq ft) 10 double rolls
46.6 to 51.1 sq.m (501 to 550 sq ft) 11 double rolls
51.1 to 55.7 sq.m (551 to 600 sq ft) 12 double rolls

Final Tip

You always want to order a little too much instead of not enough. The last thing you want is to run out of wallpaper and have to reorder since it is difficult at times to get the same lot and range of colours. To keep things simple and to ensure you have enough paper do not make any deductions for windows, doors, cabinets, etc. If you are confused about the installation, get the assistance of a local professional wallpaper hanger, however this is no impossible work for you to do it on your own by following a process.
