Upgrading the existing composite, steel, or wood doors on your home to new wrought iron doors gives your home a modern and updated look. Your investment into the new doors also will pay for itself should you ever decide to sell your home.

Determining what size iron doors you need is not that difficult. All you need are the following items:

  • Tape Measure: You need a retractable model that can be extended long distances.
  • Notepad: You will want to grab a notepad where you will make a rough sketch of the door you are measuring.
  • Pen or Pencil: You will need to write down your measurements in your notepad.

It can be beneficial to ask someone to help you with the measuring process if you want an extra set of hands. We also recommend you take each measurement twice to ensure accuracy.

Step 1: Measure the Width of the Door

From the inside of the home, with the door closed, you will measure from the left door jamb to the right door jamb. The door jamb is also called the door frame and is the area the door shuts and seals around. For instance, a commonly used door width is 36 inches.

You will want to take door width measurements at three key locations:

  • Bottom of the Door
  • Middle of the Door
  • Top of the Door

Taking measurements at each of these areas helps let you know if the door frame is warped. The measurements should be the same. If not, it might be necessary to replace the door frame when you get your new iron entry door.

Step 2: Measure the Height of the Door

How to Measure an Iron DoorFrom the inside of the home, with the door closed, you will next measure from the bottom of the door to the top, just inside the upper door jamb. Take the measurement from the middle of the door. You can also measure the edge of each side of the door to verify that the measurements are the same.

Step 3: Measure the Depth of the Door

The door depth is the thickness of the door. You will need to open the door to take this measurement. Measure on the side of the door that has the doorknob and deadbolt. Record the depth at the top, middle, and lower part of the door.

Step 4: Measure the Width of the Door and Door Jamb (Frame)

From outside the house, measure the combined width of the door and door jamb. Take measurements at the top, the middle, and the lower part of the door.

Other Measurements and Considerations

If you have decorative windows around your front entry door and want to upgrade these to iron decorative windows as well, you will need to measure the width and height of each window frame. For curved or arched windows above the entryway, measure the length at the bottom and the height at the peak of the arch.
