Mounting Specifics, Measure and Fit Your Door 

Casing or No Casing ?

First, you need to determine whether or not there is casing (often referred to as trim) around your opening, or if it is simply a sheetrocked door opening. 

-This is the most important detail to get started as it will affect the size of your barn door. It is possible that your opening has been sheetrocked all the way around and does not have a jamb or casing.  This is very common in new construction.

If your door is sheetrock only you can slide down the page to the sheetrocked opening section!
Width: In instances where casing is present we recommend building the door to the same size as the opening + casing.  Measure from the outside of the casing to the outside of the casing for the door width.  (In this example the total width is 38″).
Height: For the door height we recommend measuring from the floor to the top of the casing.  (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.  The graphic below simulated a door over the opening.

DOORS WITH Sheetrocked Opening (No Trim or Casing)

Width: Measure from inside to inside of the opening. Add 4″ to the measurement and you have your recommended door width.   (In this example the opening width is 32″ +4″).  Total door width will be 36″

Why add 4″? The door will need to hang off the wall a couple of inches in order to slide.  As a result, the door must be wider than the opening to eliminate sight lines from angles around the opening. 

In the example above involving casing, the casing already ‘frames’ the door and adds 4-6 inches of width to the door that will generously cover the opening.  For sheetrocked openings you want to add the extra door width to accomplish the same result.

Height: For the door height we recommend measuring from the floor to the top of the opening.  (In this example the total height is 80″)

Once mounted the door will hang ~1″ off the floor which will add the bit of coverage you need at the top of the opening.

**Once you’ve established your desired door size.  Double check to make sure you still have enough space for the full door to slide out of the way.

**Depending on the style of the door, don’t forget to note which way your new sliding barn door will slide.  This may affect how the door is built as well as the handle location.

**Distance from top of door to ceiling must be a minimum of 6”.

When mounting track a 3/4 x 4” edger board must be attached to the wall.


**Two (2) doors side by side are referred to as bi-parting doors and need two (2) track systems -one (1) for each door.
