There truly is a difference between a sticker and a decal; however, on our site we refer to them essentially as the same thing. Everyone has a different opinion when it comes to this question. According to StickyLife.com a sticker is a single, flat, solid, uniformed paper or vinyl with an adhesive backing and a graphic that communicates a particular message to a given audience. A decal is basically the same thing as a sticker, but may not be a single piece and requires some form of transfer paper to help maintain a specific layout during application. You can find a more detailed explanation of these differences in our How To section on the Decals vs Stickers vs Static Clings page.
