Classic Single Barn Door Kit | Black Hardware

Door width: Measure your rough opening width. For a standard room, add 4 in (2 in overlap each side). For a bedroom or bathroom where privacy overlap matters more, add 6 in (3 in each side). Minimum is opening + 1 in (1/2 in each side). Select the door width closest to that result from the available sizes. The largest kit door is 54 in wide — for openings wider than 50 in, a double door kit may be a better fit.

Door height: Select 80 in or 84 in based on your ceiling height and opening height. The door should be at least 1 in taller than the opening — more is fine — to leave adequate floor clearance. On carpet or uneven floors, confirm there is enough clearance for the door to slide without dragging.

Track length: Determined automatically by the door width you select — see the sizing table in the "Choosing the right door width" section below. The track ships with the kit.

Ceiling clearance: The clearance required between the top of the door and the ceiling depends on your roller type. Straight Strap and Straight Top Mount require 5 in; J-Strap, Arrow, and Diamond require 6 in; Spoke Wheel requires 8 in. Measure this gap before selecting a roller style.

Wall header: A solid header above the opening is required for track mounting. If there is no existing header or backing in the wall, install a minimum 1×6 hardwood board (3/4 in thick × 5-1/2 in wide) that extends past the length of the track to the next stud or structural support point on each side. No solid header and cannot install one? See ceiling mount hardware.

Wall clearance: The door slides to the side of the opening. You need at least as much clear wall space beside the opening as the door is wide — confirm there are no light switches, outlets, or trim obstructions in the path.

Start with your rough opening width. Add 4 in for standard rooms (2 in each side) or 6 in for bedrooms and bathrooms (3 in each side). Select the door width closest to that result from the available sizes. The track length ships automatically with your kit based on the door width you select — you don't order the track separately.

The minimum door width is 2 in wider than your opening (1 in per side), though this barely covers the jamb frame and isn't ideal for most installations. We recommend at least 4 in wider for standard rooms (2 in per side) and 6 in wider for bedrooms and bathrooms (3 in per side). The sizing reference table shows the absolute maximum opening each door can cover at the 1 in per side minimum — use those figures as a ceiling, not a target. Track lengths run from 4 ft (22 in door) up to 10 ft (54 in door).

For the complete door width, maximum opening, and track length reference chart, see our Classic Single sizing table.

If your opening is wider than 48 in and you need a door larger than 54 in, a double door biparting kit is likely the better fit — two doors that slide from opposite sides cover larger openings without requiring an oversized single panel.
