How To Measure A Grille:

Overall Size:
Measure the size of the air duct/drywall opening. 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 2 5/8".

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 20x14 grille. If your hole is 14" wide by 20" tall, order a 14x20 grille.
