In order for a sliding barn door to function correctly, a track is needed to help it slide left to right. The rule is multiplying a barn door’s width by two to get the perfect size track for a barn door.

If the barn door has a standard width of 36 inches or around 91 centimeters, the ideal track length is multiplying 36 inches by 2, giving a product 72 inches or 183 centimeters. This makes knowing the width of a particular barn door essential for correct track measurement. 

How To Measure For Barn Door

In measuring, there are four things a homeowner needs: tape measure, pencil, paper, and a step stool. 

The first thing to do is gauge the measurement of the doorway. This will include measuring the height from top to bottom and the width from left to right. This will ensure that the barn door will fit without any scraping of bumping. 

The next is measuring the door frame width, including the available wall space. This is needed because the barn door must be larger than the opening. To do this, measure from left to right inside the door trim. 

With that dimensions, adding an allowance of 2 to 4 inches or about 5 to 10 centimeters will ensure that the entryway is completely covered without even a slight opening. The subsequent measurement is measuring where the door will slide. There should be enough space for the barn door to slide in to be functional ultimately. 

The third is measuring the height. This will include the measurement for the track to be mounted. It can be fixed halfway on the door and the ceiling or on top of the door itself. To do this, measure from the floor to the top of the edge of the door trim or higher than this and then subtract around an inch or 3 centimeters. 

The last is deciding on the track length. This can be determined by taking the barn door width and multiplying it by two. This is a rule of thumb for single barn doors; going four times the width of one door is required for double doors.
