Modern door heights are fairly standardized (80", 84", 96"). Our collection of antique salvage doors will not always fit nicely into those dimensions. As an example, many interior doors were cut down when carpeting was installed.
For that reason we have assigned them each to a range of heights. Please view the product description for the exact dimensions. If you are looking for an 80" door, you will find doors that range from 79" to 80-1/4" - all of which can be used in an 80" opening.
