How To Measure A Grille
Always measure the size of the duct opening (the “hole” in the duct/wall). Do not measure the entire size of the register itself. Size of the grille is; listed size +1.75-inch.

Understanding Width & Height
In a grille size, the first number always represents the width and the second one is the height. As an Example: If the hole on your wall/duct is 16″ wide by 20″ tall, order a 16×20. If the hole is 20″ wide by 16″ tall, order an 20×16.

For this particular product you’re viewing at the moment, the hole on your wall/duct opening should be 16″Wx20″H.
