4. Frame SizeMeasure the size of the door frame to ensure the replacement door fits snugly within the frame. Take measurements of both the height and width of the frame.
5. Hinge PlacementNote the location and dimensions of the existing door’s hinge cutouts, as they need to align with the replacement door for proper installation.
6. Door SwingDetermine the door swing direction (inward or outward), as it affects the handing of the replacement door.
7. Threshold HeightMeasure the height of the threshold to ensure the replacement door’s bottom aligns properly, allowing for smooth operation.

2. How do I measure the door’s jamb width?

The jamb width can be measured by measuring the interior width of the door frame, including any trim or casing.

3. Should I measure the old door or the door frame?
