Size Guide - Barn doors

Available Sizes

Door Type	Min Width	Max Width	Min Height	Max Height
Single Door	24"	54"	80"	102"
Double Door	48"	108"	80"	102"

Any size within this range can be pre-ordered. Doors come pre-hung in a steel frame — listed sizes include the frame.

How to Measure

Width: Measure the opening and ensure the wall has enough space on one or both sides for the door(s) to slide open fully.
Height: Measure from the floor to the top of the opening.
Clearance: Allow at least 6" above the opening for the track, and 2–2.5" from the ceiling. Leave 0.4–0.6" beneath the door for the floor guide. We recommend making the door 1.5–2" wider than the opening to ensure full coverage and avoid gaps.

Note: Barn doors do not require a jamb or frame. The track system should be mounted into solid wood blocking or wall studs for best support.

Size Guide - Arched doors

Available Sizes

Door Type	Min Width	Max Width	Min Height	Max Height
Single Door	24"	54"	78"	106"
Double Door	48"	108"	78"	106"

Any size within this range can be pre-ordered. Doors come pre-hung in a steel frame — listed sizes include the frame.

How to Measure

Width: Measure the opening at the top, middle, and bottom. Use the smallest of the three measurements.
Alignment: Use a level to make sure the sides are straight and plumb.
Height: Measure at the center of the arch — or the highest point of the opening if it’s square.

Note: For rough openings, we recommend adding 0.5" to both the width and height to allow for finishing and easy installation.
