Measure Your Entryway – for Pre-hung Units Only
- To ensure accurate measurements, first remove the interior casing on the sides and top of your single or double door to reveal rough opening frame.
- Measure from inside the face of one stud to inside the face of the other stud and write down the measurement.
- Measure from the subfloor (plywood or concrete) to the bottom of the header above the door and write down the measurement.
