Measure from outside to outside of casing molding.
How much overlap for barn doors.
I used 7 6 slats which made my doors 42 wide and since my opening is 38 i was able to get 4 of overlap on the doors.
Barn doors can be installed to overlap each other but it requires a different installation technique and barn door hardware which can increase cost.
Add 1 to 2 per door for overlap depending on privacy needs.
Ideally the door will cover 2 to 3 inches beyond the opening on each side.
Measure across for the width and from the top of the casing molding to the floor for height.
The doors will need to be offset from each other on the track or sometimes even use an extra track.
To figure out what size track you need double your final width measurement.
Barn door measuring guide for door openings with casing molding.
The wall that the door rests on when it is fully open has to be at least the same width as one door.
Doors wider than 24 5 would work just fine but you loose access width when the doors are open.
Your door s width should be 2 to 3 inches wider than the door opening and 1 inch higher than the dimensions of your opening.
Measure from the header to the floor to determine the door length you need.
A one inch overlap is about ideal so for a 48 finished opening each door would be 24 5 inches wide.
Again for doorways with moldings measure from the top edge.
