If you buy too few wallpaper, they will not be enough to finish all the walls, and if there are too many, there will be excesses that have nowhere to put. To avoid these problems, it is important to correctly calculate their right amount.
The wallpaper calculator simplifies the calculation process and minimizes errors. But in order for the calculations to be accurate, it is important to correctly measure the area of the walls and take into account the features of the wallpaper that you are going to glue. In this article you will not only find a wallpaper calculator, but also find out how to take into account all the nuances for the accuracy of calculations.

First step: measurement
To accurately calculate the number of wallpaper, it is necessary to carry out a number of measurements. Start by measuring the length and width of the walls. Measure each wall separately. Then measure the height of each wall from the floor to the ceiling. This value should also be recorded.
Also, for the exact calculation of wallpaper, it is necessary to subtract the area of windows and doors from the total area of the walls. Measure the height and width of each window and door. For example, if the window has dimensions 1.5 m per 1.2 m, its area will be 1.8 m² (1.5 m * 1.2 m).
Suppose you measured your room and received the following data:
- Wall length: 5 m and 3 m (two each 5 m and two 3 m).
- Ceiling height: 2.7 m.
- Window: 1.5 m per 1.2 m.
- Door: 2 m by 0.9 m.
They can be inserted into a calculator if you have simple wallpapers without a pattern with a selection.
Second step: taking into account wallpaper features
When choosing wallpaper, it is important to consider several key parameters. One of them is the width and length of the roll. Once upon a time, all the wallpaper had a width of 53 cm and a length of 10 m. However, now more often there are wallpaper with a width of 70 cm or 1 m, and the length of the roll can vary from 5 to 25 meters.
For example, for a wall with a length of 5 meters and a ceiling height of 2.7 meters, a small roll of 53 cm wide and 10 m long is enough for 3 vertical stripes (each strip will cover an area of 1.43 m²). But if the roll is wider, for example, 1 meter, then from one such roll you can get 5 lanes, each of which will cover an area of 2.7 m². Thus, you will need fewer rolls.
Another important parameter is a repetition of a pattern or rapport. Rapport is the distance through which the drawing on the wallpaper is repeated. For example, if the wallpaper has a rapport of 30 cm, then every 30 cm the drawing will begin again. This value must be taken into account when calculating the number of wallpaper, since additional material will be required to fit the pattern. The more rapport, the more waste. Suppose you have a room with a ceiling height of 2.7 meters and a rapport of 30 cm. In this case, in order to match the picture, you will need to cut off each strip at least 3 meters long (2.7 m height + 0.3 m rapport). Accordingly, from a roll 10 m long you can get only 3 stripes, and the remaining piece will be a waste.
Third step: enter the data into the wallpaper calculator
First you need to enter the parameters of the room. For example, if the room is rectangular, the length of one wall is 5 meters, and the other is 3 meters. The height of the ceiling is 2.7 meters. These data are entered into the corresponding fields of the calculator.
Then it is necessary to take into account door and window openings. If the room has one window in size 1.5 by 1.2 meters and a 2 for 0.9 meters door, their area is also inserted into the calculator to exclude these areas from the general calculation.
Next, you should specify the wallpaper parameters that you plan to use. Indicate the length and width of the roll, as well as a rapport (the step of the picture indicated on the roll).

Additional tips and recommendations for calculating the number of wallpaper
To avoid mistakes, you need to carefully measure all the parameters of the room. Use a long roulette and make sure that it is stretched in a straight line. This will help to avoid distortions and inaccuracies. Take measurements several times, especially if the room has complex geometry with niches and protrusions. Do not forget to take into account all windows and doors - their area will need to be subtracted from the total area of the walls.
Pay special attention to measuring the height of the walls. Even small deviations can lead to the fact that there are not enough wallpaper or there will be too many.
If after all the calculations you have doubts about the number of wallpaper, it is better to play it safe and take with a small margin. For example, if you need 8 rolls according to calculations, take 9. This is especially important if you buy wallpaper from a limited collection, which will then be difficult to find.
In addition, even with the most thorough calculations, unforeseen situations may occur. For example, you can damage the wallpaper when sticker or make a mistake in fitting the pattern. Therefore, it is recommended to buy wallpaper with a margin. The usual stock is 10-15 % of the total number of wallpaper.
In conclusion
The main parameters that must be taken into account when choosing wallpaper are the area of the walls, width and length of the roll, as well as the step of the drawing (rapport). Each of these characteristics has a direct effect on the amount of material necessary.
When working with an online wallpaper calculator, it is important to consider the area of door and window openings and indicate all the wallpaper parameters. This will help to accurately calculate the amount of material and avoid overrun. A supply of 10-15 % of the total number of wallpaper will help reduce the risk of problems.
