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. Each grille has a front face frame, that will overlay at wall joint. Entire outer size of the grille is; listed size +2 5/8-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 a 24x18. If the hole is 18" wide by 24" tall, order an 18x24.
For this particular product you're viewing at the moment, the hole on your wall/duct opening should be 24"Wx18"H.
