WHAT SIZE DOOR SHOULD I GET?
HOW TO FIND THE RIGHT BARN DOOR SIZES
Step 1: Measure Your Home’s Doorways
Measure the doorways, stairways, and hallways leading to the room where your barn door will live. Take note of the height (top to bottom) and width (left to right) for each. These measurements will tell you what size barn door you’ll be able to fit into your house without bumping or scraping.
Step 2: Find the Right Width
Measure Door Frame Width
The barn door you choose needs to be slightly larger than the opening of the door frame it will cover. If your doorway doesn't have a trim, measure the width of the inside of the door frame from left to right. Add 2" – 4" to this measurement, so your barn door completely covers the entryway without drafts or slight openings.
If your doorway does have a trim, measure the width of the door frame from one edge of the trim to the other. Again, add 2" – 4" to that dimension.
Measure Available Wall Space - Sliding Barn Door Measurements
Measure where your door will slide. Use a pencil to mark the door opening’s width measurements. Is there enough space on either side of the opening for the door slab to slide all the way open? If your measurements run into a wall, outlet, or other immovable object on either side, there is not enough room for a sliding barn door. If you have double barn doors, make sure there is enough wall space on either side of the doorway for both doors to fully clear the opening.
Step 3: Find the Right Height
Consider Track Placement
To ensure you pick the right height, determine how far above the door you want the track to be mounted. Tracks are horizontal rails used to slide a door smoothly across a doorway – barn doors are attached to a track set above the doorway. Tracks are most often mounted halfway between the ceiling and the top of the doorway or directly above the door frame. In pencil, mark where you will be placing the barn door track for easy reference.
Measure Height
If you will be placing your track right above the trim or doorway, measure from the floor to the top edge of your door's trim or edge. Then subtract 1" to ensure that your door can close without scratching the floor. If your door track will be placed higher than this, measure from the floor to the pencil mark on your wall, then also subtract 1".
Step 4: Determine Track Length
Now that you have your ideal barn door size, determine what track length to buy. Take the width measurement for your new barn door and multiple it by two. This is how long your track length should be at minimum for a single sliding door. You can extend the track length for stylistic reasons if you wish. If you have a double door, you will need a track that is four times the width of one barn door.
