Ordering a custom iron door starts with the right measurement. A small mistake in width, height, or frame condition can change the quote, delay production, or require extra installation work. For Dallas-Fort Worth homeowners, the best starting point is the rough opening, not just the visible door slab.
What Is the Rough Opening?
The rough opening is the framed space where the new door system will be installed. It is measured from jack stud to jack stud for width, and from the header down to the finished floor for height. This measurement helps confirm whether your home needs a standard size, a modified size, or a fully custom iron door.
Basic Measuring Steps
- Measure the width at the top, middle, and bottom of the opening.
- Measure the height on the left, center, and right side.
- Check whether the floor is tile, concrete, hardwood, or unfinished.
- Look for existing casing, brick, stucco, or trim that may need removal.
- Take clear photos from inside and outside the home.
Why Casing and Frame Condition Matter
Many homeowners measure only the visible door, but a custom iron door is installed into the structure around the opening. The installer may need to remove casing to confirm the true opening and inspect whether the wood frame can support a heavy iron system.
Single Door vs. Double Door Measurements
A single iron French door usually requires less framing work than a wide double door. A double iron French door can create a larger entrance, but the opening must be checked carefully for header support, side clearance, and swing direction.
When to Request a Site Measurement
If your opening is unusual, your home has brick walls, or you are replacing a wood door with a heavier iron system, a site measurement is the safer option. Texas Glass Door can review your opening, confirm the size, and help prepare the quote before production.
