The difference between a wall decal and a wall sticker

So what is the deal with a "wall decal" or a "wall sticker"? They both sound the same and you may find both terminology on 999decals. You might even ask yourself why we are calling everything decals on our site? The reason for this is quite simple: geography. Like color instead of colour, decals is a term that is used a lot more in the United States and Australia than in Europe. So since we are based in north america, we decided to make things simple and call them WALL DECALS
Decals often consist of several separate part like letters or patterns, because thanks to the transfer surface they can be attached on the wall exactly with the same spacing as they were designed to have. Decals are almost always made out of PVC-vinyl, because very often they are applied on places where you need the elasticity that the plasticisers give. If you see that a decal is called a vinyl decal that usually means it’s made of soft PVC-vinyl. We however prefer polyester before PVC.
Stickers can be made of a whole range of different materials, but most often they are printed on PVC-vinyl or polyester.
