How to Measure Iron Doors: Iron Door Sizing Guide

Before you begin the iron door installation process, it's essential to measure your space accurately. Follow our iron door sizing guide to ensure that the door fits perfectly and allows for easy installation. We recommend that you measure the rough opening carefully and allow extra space for leveling, insulation, and proper hardware installation.

If you're unsure about the measurements or need assistance, feel free to reach out to our team for guidance on how to measure iron doors for your specific project.

Our door sizes are listed as the outer dimensions of the jamb, not the actual door slab.

For example, a 72” x 81” door means:

• 72” is the total width from the outside of the jamb to the outside of the jamb
• 81” is the total height from the top of the jamb to the bottom of the built-in steel threshold

These are not the measurements of the door itself.

Recommended Rough Opening for Iron Door Installation

To ensure a proper fit and easy installation of your custom iron door:

• Your rough opening width should be ½” to 1” wider than the width of the door size listed
• Your rough opening height should be ½” to 1” taller than the height of the door size listed

This allows your installer enough space to level and secure the jamb properly, ensuring your iron door installation goes smoothly and fits perfectly.

Iron Door Features

Our doors are designed for durability and performance. They come with a standard jamb size of 2" x 6" and feature 0.55" iron bar scrollwork for an elegant, sturdy design. The double-pane insulated tempered glass (5mm + 9mm air + 5mm) offers superior thermal insulation and energy efficiency, making them ideal for both residential and commercial properties.

Each door includes essential hardware such as flush bolts, weather strips, and drop seals to ensure a secure and weather-tight fit. To enhance durability and energy efficiency, all tubes, kickplate, and threshold are injected with polystyrene foam. The threshold is designed to slope downward, ensuring water flows away from the door, keeping the area dry and protected.
