Wallpaper comes in different lengths and widths and, although usually priced by the single roll, it is packaged either as double or triple rolls. People may find this packaging versus pricing situation hard to understand. However, wallpaper is packaged this way because double and triple rolls provide more usable wallpaper than single rolls. In addition, extra wallpaper allows for a margin of error during hanging, will help avoid the problem of finding the same dye lot or printing run when reordering to complete a project, or if the wallpaper on the wall has been damaged and needs repair.
Important things to note:
- Wallpapers can be manufactured in different widths -- primarily due to different equipment in different factories.
- Metric, also called Euro, single rolls have between 27 1/2 and 29 square feet. Double rolls have 56 to 58 square feet.
- American single rolls, which are being phased out, are packaged with almost 25 percent more wallpaper than a metric roll. American single rolls, regardless of their lengths and widths, usually have about 36 square feet of surface; double roll bolts about 72 square feet and triple roll bolts between 101 and 108 square feet.
