📐How to Measure Your Interior Door

Accurate measurements are crucial when ordering a new iron door to guarantee a flawless fit. Our step-by-step guide makes measuring easy, helping you avoid installation issues. Whether you're replacing an existing door or installing a new one, follow these simple instructions to ensure the perfect fit for your new pre-hung interior steel door.

Tools You’ll Need:

• Measuring tape (preferably metal for precision)
• Paper and pen or phone (to note measurements)
• Ladder (if measuring a tall opening)
• Level (to check alignment)
• A friend or two (for moral support and to blame if the measurements are off!) 😆

All interior doors from IronDoor.com come with a Pre-Welded Jamb ready for installation. No jamb assembly is required on-site, ensuring a precise fit and greater structural integrity.

* The door featured here is an 72" x 96" Openair 23 Black French Steel Interior Door.

The recommended rough opening for this interior door is 72.5" x 96.25", allowing space for adjustments to ensure a precise fit. You typically want to make sure your rough opening is 1/4" taller and 1/2" wider than the interior door.

Note: The clearance spacing under the door is 5mm.

Conclusion

Properly measuring your door ensures a perfect fit and smoother installation. If you’re unsure about your measurements, consider hiring a professional. Steel doors are heavy and require precision, so it’s essential to get it right the first time!
