Modern wallcoverings are diverse. Two of the most common factory trimmed sizes of wallpaper are referred to as "American" and "European" rolled goods. American rolled good are 27 inches by 27 feet in length. European rolled goods are 21.5 inches wide by 33 feet in length. Approx. 60 square feet. Most wallpaper borders are sold by linear foot and with a wide range of widths therefore square footage is not applicable. Although some may require trimming. The most common wall covering for residential use and generally the most economical is prepasted vinyl coated paper, commonly called "strippable" which can be misleading. Clothed backed vinyl is fairly common and durable. Lighter
vinyls are easier to handle and hang. Paper backed vinyls are generally more expensive, significantly more difficult to hang, and can be found wider untrimmed widths. Foil wallpaper generally has paper backing and can (exceptionally) be up to 36 inches wide, and be very difficult to handle and hang. Textile wallpapers include silks, linens, grass cloths, strings, rattan, and actual impressed leaves. There are acoustical wall carpets to reduce sound. Customized wallcoverings are available at high prices and most often have minimum roll orders. Solid vinyl with a cloth backing is most common commercial wallcovering and comes from the factory as untrimmed at 54 inches approximately, to be overlapped and double cut by the installer. This same type can be pre-trimmed at the factory to 27 inches approx.
