HOW TO MEASURE FOR A REPLACEMENT DOOR
1. Determine if you need an outswing door or combination outswing and storm door.
2. If measuring for an outswing door measure the width and height while standing outside the home.
For width, measure from the left edge of the door to the right, taking three horizontal
measurements. Record the smallest size, which is what you will order. For height, take three
vertical measurements from the top of the core of the door to the bottom and record the smallest.
3. To determine the hand of the door needed, stand outside the home and determine which side the
hinges are installed. This is the hand of the door and is true for both outswing and combo doors.

4. To measure the width of a combo door, measure the storm door core and add 2” rounding to the
nearest even number. For example, if your measurement is
32 1/8” you would order a 34” door. To measure height on a combo door, measure the height of the
storm door core and add 1” rounding to the nearest even number. For example, if the height
measurement is 80 ¾” add 1” and order an 82” door.
5. Finally, measure the depth of the door jamb from the interior edge of the jamb to the weather
stripping on the door stop.
