Wallpaper calculation

To perform calculations on the wallpaper calculator, you need to know the following parameters:
Perimeter of the walls to be covered in meters;
Wall height;

Width, height of the door, windows in the room;
Width and length of the rolls – specified on the packaging of the selected wallpaper (wallpaper width ranges from 0.4 to 1.6 meters, and the length from 7 to 18 meters).

To calculate the necessary number of panels for wallpapering in a room, you need to:
Room perimeter/roll width. For example, our room has a perimeter of 35 meters, and wallpaper with a width of 0.75 meters. We calculate: 35/0,75=46.67, rounding up gives us – 47 panels.

Now you need to calculate how many panels are in one roll. To do this, divide the roll length by the room height. For example, the height – 2.5 meters, and the roll length – 12 meters. We get – 4.8 panels, rounding – 4.
For counting the required number of rolls for the room. Divide the number of panels needed for the room by the number of panels in one roll. In our case: 47/4=11.75, which means 12 rolls.

Remember not to throw away leftover wallpaper after renovation, as it will be extremely difficult to find them for sale in a few years, and they may be needed for unforeseen repairs!, for example: replacing torn wallpaper that your new cat had fun with, walls drawn on by a small child, floods, and a number of other natural causes.
