In addition to material, wallpaper specifications are also very important when choosing home interior wallpaper. The calculation methods and steps of home interior wallpaper are often difficult for consumers. When we buy home interior wallpaper, we will encounter some problems, such as how many pieces to buy, what specifications to buy and so on. Now let's teach you how to calculate the amount of home interior wallpaper to be used.

Step 1: Understand home interior wallpaper's specifications

For our home interior wallpaper, there are six sizes: 77*70cm, 75*66cm, 71*66cm, 72*63cm, 60*60cm, 1*20m. For example, 75*66cm=0.495m2, so one square metre should be used two pieces.

Step 2: Measure room's size
1. Measure the wall height of the home interior wallpaper part of the room 2. Measure the wall width of the home interior wallpaper part of the room.
For example, room height is 2.8m, room width is 10m, room area is 28 square meters, wallpaper specification is 77*70cm, and then will need 56 pieces.
In order to prevent the problem that there may be no same batch number in replenishment, more calculation should be made in calculating the number of home interior wallpaper. If there is excess home interior wallpaper after construction, it can be replaced.
