There are NO INDUSTRY STANDARDS OR SIZES in mail slots, therefore you need to MEASURE ACCURATELY.
Successful purchases and installations depend entirely on accurate measurements.
One manufacturer’s “magazine” size may be another manufacturer’s “letter” size. Even our “Elite” magazine size is a different size from our “Classic Surface Mount” magazine size.
The likelihood of dissatisfaction is substantial with inaccurate measurements.
To begin, you must remove your existing mail slot to be able to measure the width and height of the actual hole cut through your door or wall.
Only the size of the actual hole cut through your door or wall determines if one of our mail slots will fit.
Although it is always easier to increase the size of an existing hole than decrease it …
How To Measure
Step 1. Remove interior AND exterior face plates of existing mail slot from your door or wall
Step 2. Measure the width and height of the “actual hole cut through your door or wall” from both the interior AND the exterior sides of your door or wall and write measurements down
Step 3. Repeat measuring process to make sure your measurements are accurate as in the adage “Measure twice, cut once”
Step 4. You now have your “Cut Out Size” measurements

Step 6. Compare your “Cut Out Size” measurements to the “Cut Out Size” measurements of one of our products
