In this example the opening width is 32 4.
How much should interior barn door overlap opening.
You re better off just putting the slats together and seeing how wide they are when you add each full slat to the set so you don t have to end up ripping one to size.
Measure from outside to outside of casing molding.
30 opening 34 wide door.
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.
For door openings with casing molding.
This greatly depends on where the doors are going.
To figure out what size track you need double your final width measurement.
Ideally the door will cover 2 to 3 inches beyond the opening on each side.
Barn doors should overlap openings by at least an 1 preferably 2 on each side.
This means on one side of the door opening or the other there should be at least 2 8 and perhaps a little more to ensure all the hardware can fit properly.
Or if you like the look of a wider door you can overlap as much as you want.
While the style of barn door you choose will come down to your personal preference you will need to be aware of barn door vs opening dimensions when making your choice.
Sheetrocked opening no trim or casing width.
Add 4 to the measurement and you have your recommended door width.
We recommend 1 1 2 to 2 of overhang on each side.
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.
Remember barn doors need to slide at least as far as the opening in one direction or the other.
Measure from the header to the floor to determine the door length you need.
To have privacy the door usually overlaps the opening by an inch so that a 2 6 opening will require a 2 8 door.
Total door width will be 36.
Again for doorways with moldings measure from the top edge.
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.
The height is a bit trickier based on the casing and header.
If the door will be replacing a bathroom door or another room that requires privacy then you might want to consider a greater overlap.
Measure from inside to inside of the opening.
