I use accurate aspect ratio on measurements. The size described is for the longest section of the decal. An estimate of a square decal aspect ratio would be 6" X 6" whereas a rectangle decals aspect ratio would be estimated at 6" x 3" Made with durable, weather resistant vinyl. Easy to apply. Application instructions included with every decal. Motorcycles - Cars - Helmets - Skateboards - Snow boards - Mirrors - Laptops - Lockers - Tool Boxes - Books - Guitars - Home Walls - Windows - Water Craft - School Folders - Boats - Trailers - ATV's - Computer Cases - Video Game Consoles - and Much Much More! What is a Die Cut Decal Computer cut letter and image outlines cut from a solid sheet of thin vinyl are called "Die Cut". This means there is no background color that is part of the decal. The background color becomes whatever surface the decal is applied to. So if a black decal is applied to a silver laptop then the background color will be silver and the decal color will be black.
