How to get the right size Decal
Using a tape measure or yard stick define the area where the decal is to be installed (windshield, side window, rear window, wing, gas tank-motorcycle, etc.) Measure with height (up and down) and width (left to right). These numbers should be in inches.
Be sure to make the decal smaller than the application surface. This will make the installation easier, and the decal will fit the area properly. For example: Most windshield decals are 4in tall by 40in wide. The actual windshield area is normally about 46in to 52 in wide, but the decal should be smaller than the application area. The standard size for window decals is 6" by 36", however you should measure to make sure that size would fit.
A NOTE ABOUT COLOR: At the same time, look at the application area and visualize the decal, and choose a color or colors for the decal. Generally a light colored decal will look best on a window or dark painted surface, while darker colors will look best on lighter surfaces. Dark colors will not show up on tinted surfaces.
Be sure also to take into consideration rear window wipers as they can cause the decal to peel lose allowing dirt underneath. This will cause your decal to become weak and damaged.
