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

For this particular product you're viewing at the moment, the hole on your wall/duct opening should be 18?ìWx12"H.
