A wall decal, also known as a wall sticker, wall tattoo, or wall vinyl, is a vinyl sticker that is affixed to a wall or other smooth surface for decoration and informational purposes. Wall decals are cut with vinyl cutting machines. Most decals use only one color, but some may have various images printed upon them.
Types and sizes
Decals can range from simple small wall borders and cut outs to more complex murals covering entire walls. They may feature words, pictures and designs. Vinyl wall decals come in various shapes and sizes. They can be as small or as large as necessary. Regular wall decals are usually between 30 cm x 50 cm and 60 cm x 100 cm. Larger decals may be 100 cm x 100 cm or larger. 
Most vinyl decals are not reusable, although some reusable vinyl types are available. These decals are usually printed images with a sort of laminate overlay; this allows the decal to be removed without being stretched.
Vinyl decals have various uses. Vinyl decals were originally only used for sign making, but they have recently been added to interior decorators portfolios and have also become well known as a Do-It-Yourself home decorating option.
Decals can be used on windows, walls or tiles as branding, advertising, or decoration. They may also serve as a tool to inform people that there is a glass door or window.
