Do not measure the overall size of the register itself, only measure the “hole” in the wall/duct. Every grille has a front end frame that will overlap at the wall joint. The total outer size of this grille is the listed size plus 1.75″ Width vs Height: The first number in a grille size represents the width, and the second number represents the height. For example, if your hole is 20″ wide by 14″ tall, order a 20×14 grille. If your hole is 14″ wide by 20″ tall, order a 14×20 grille.
