In this example the total height is 83 when closed over the opening the door will cover all of the casing for a cohesive look.
Barn door height.
For instance if you have a doorway that s 35 you ll want a track that s at least 70 although a safe 6ft.
Measure across for the width and from the top of the casing molding to the floor for height.
Add 1 to 2 per door for overlap depending on privacy needs.
Generally most standard barn doors are approximately 36 x 84 or 42 x 80 with enough extra lip to overlap most standard door frames 36 x 80 by an inch or so.
The graphic below simulated a door over the opening.
Most barn door sizes fall anywhere between 36 wide on the shorter side by 96 tall on the longer side.
Always remember that your barn door railing system should be at least double the width of your door frame possibly longer if you have an odd shaped door.
For the door height we recommend measuring from the floor to the top of the casing.
