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 24″ wide by 18″ tall, order 24×18 option. If the hole is 18″ wide by 24″ tall, order 18×24 option.

For this particular product you’re viewing at the moment, the hole on your wall/duct opening should be 24″Wx18″H.
