before purchasing wallpapers, you should estimate the dosage, so as to buy enough Wallpapers of the same batch number at one time, reduce unnecessary trouble and avoid waste. The amount of wallpaper is calculated with the following formula:

wallpaper amount (roll) = room perimeter × Room height × (100 + k)/number of square meters per roll, K is the wastage rate of wallpaper, generally 3-10. Generally, each roll of standard wallpaper can cover 5.2 square meters

and the size of K value is related to the following factors:

1. Wallpaper pattern size: large pattern stitching is complex for flowers, so the utilization rate is lower than that of small pattern wallpaper, so the K value is slightly larger; The pattern that needs to pair flowers has a lower utilization rate than the pattern that does not need to pair flowers, and the K value is slightly larger; The pattern arranged in the same direction has lower utilization than the pattern arranged horizontally, and the K value is slightly larger

2. Nature of mounting surface: those with complex mounting surface need more wallpaper than ordinary planes, and the K value is high

3. Mounting method: the use rate of butt joint wallpaper is high and the K value is small by mounting with splicing method, while the use rate of wallpaper mounted with overlapping cutting and splicing method is low and the K value is large

it can be seen from the wallpaper calculation formula above that even in the same room, the amount of wallpaper with different textures and colors is different. When purchasing wallpaper, you should consult the wallpaper salesperson in detail and calculate the amount of wallpaper after determining the variety
