The outside dimensions of all universal panels are 44" wide x 32" high. The design may bleed off one or more sides and can be trimmed without harming the design. Or, as shown in the illustration above, designs may be 23, 30 or 36 inches wide. You choose the design width that allows you to trim the overall panel to size without cutting into the design. The difference between the design width and 44 inches is the space that your trim must fall within to preserve the design.

Door panels come in sets of two, a right and a left, with the design centered in each panel There are several panel styles that can be used as double sets for a 4-door car. The second set can be reversed so that the design flows through from the front door to the rear door. The Healy Flow-Thru Design, show below, is a good example.
