Double bypass sliding barn doors are a practical choice when you want two panels to slide across one another instead of swinging into the room. The SMARTSTANDARD 36-by-84-inch wood set is best for wider openings, while its 30-by-84-inch set better suits narrower spaces. A prefinished MDF option is designed for easier cleaning, and the frosted-glass set adds light while maintaining some privacy. The AWDIA product is hardware only, so choose it if you already have compatible doors and want a bifold system instead.

SMARTSTANDARD 36-Inch Double Wood Set
This set includes two natural-wood doors, each 36 inches wide and 84 inches high, plus 6.6 feet of bypass hardware. Each door is 1 3/8 inches thick, with a stated 1/2-inch solid core thickness. The doors are pre-drilled, can be flipped in either direction, and have a premade bottom groove for the floor guide.
Best for: Buyers with a wider opening who want a natural-wood double-door set with hardware included. It was selected for its 36-inch panels and longer included track compared with the 30-inch option.
Consider: The seller notes that small gaps may appear between the boards after installation as part of preparing the natural wood for shipment. The doors and hardware ship in three separate packages, so deliveries may arrive separately.
SMARTSTANDARD 30-Inch Double Wood Set
This model pairs two 30-by-84-inch natural-wood doors with a 5-foot bypass track. The panels are 1 3/8 inches thick, are pre-drilled for installation, and can be flipped in either direction. A bottom groove is included for the floor guide, and the listing says installation instructions are supplied.
Best for: Buyers who need the same general natural-wood setup as the larger SMARTSTANDARD set but prefer 30-inch panels and a 5-foot track. Compare the opening dimensions and track requirements before selecting it.
Consider: The seller says small gaps between boards may be visible after installation and that the natural wood may expand as it absorbs moisture. The doors and hardware ship in three packages.
SMARTSTANDARD 28-Inch MDF Double Doors
This double-door set has two 28-by-84-inch panels and 5-foot bypass hardware. The doors are made from primed MDF and have a prefinished PVC surface described as water-resistant, scratch-resistant, and easy to clean. The listing describes the MDF as flatter and less likely to bend than wood doors.
Best for: Households that prioritize a smooth, easy-care surface, including families with pets. The bypass configuration lets the two panels slide across one another, helping reduce the space needed for door swings.
Consider: The listed panels are 28 inches wide each, so verify that their combined coverage and the hardware arrangement suit your opening. The product details do not specify the same natural-wood construction as the other SMARTSTANDARD options.
AWDIA 52-Inch Bifold Hardware Kit
This is a hardware kit, not a complete door set. It is designed for two door panels up to 24 inches wide each. The package lists a 52-inch track, rollers and brackets, connectors, hinges, floor guides, screws, and a strip seal. The stated door limits are up to 330 pounds and 1 to 1.58 inches thick, with 6 inches of clearance required above the door.
Best for: Buyers who already have suitable door panels and want a bifold sliding setup. It is included as a related alternative for shoppers comparing ways to save space with paired doors.
Consider: Doors are not included, and this is a bifold kit rather than a complete double bypass door set. Check the panel dimensions, thickness, weight, and overhead clearance before buying.
SMARTSTANDARD Double Frosted-Glass Set
This set combines two 36-by-84-inch glass barn doors with 6.6-foot bypass hardware. The high-hardness frosted glass is described as allowing some transparency while retaining a degree of privacy. The listing also describes a prefinished PVC surface as water-resistant, scratch-resistant, and easy to clean.
Best for: Buyers who want a double sliding door design that admits light while obscuring a clear view through the panels. It offers a different look and privacy level from the natural-wood sets.
Consider: Frosted glass provides a degree of privacy, not complete visual separation. Check the opening dimensions and consider whether the amount of transparency suits the room.
Buying Guide: How To Choose Double Bypass Barn Doors
What door width and track length do you need?
Measure the opening and the wall area where the doors will slide. Compare those measurements with each panel width and the included track length. The listed sets include 28-, 30-, or 36-inch-wide panels, with either 5-foot or 6.6-foot hardware. Do not assume that a panel’s stated width alone confirms coverage; check how the doors overlap and move on the track.
Should you choose wood, MDF, or frosted glass?
Natural wood offers a distinct board appearance, but the listed seller notes possible gaps between boards and potential expansion as the wood absorbs moisture. The MDF option has a prefinished PVC surface intended to be easier to clean. Frosted glass can bring light into a space while providing partial privacy. Choose based on appearance, cleaning needs, and the privacy required.
Is the product a complete set?
Confirm whether the listing includes both door panels and bypass hardware. The SMARTSTANDARD products above are described as door-and-hardware sets. The AWDIA product is hardware only, and its stated configuration is bifold. Check any project’s door thickness, panel width, weight, and clearance requirements against the kit specifications.
What should you check before installation?
Confirm that the wall and installation area can accommodate the track and moving panels. Review the included instructions and required floor-guide arrangement. For natural-wood doors, account for the seller’s note about small gaps and moisture-related expansion. Also plan for separate package deliveries where specified.
Frequently Asked Questions
What does bypass mean for barn doors?
Bypass doors slide across one another on a track system, rather than requiring each panel to swing into the room. This can reduce the space needed for door movement.
Do these products include doors and hardware?
The SMARTSTANDARD wood, MDF, and glass listings describe door sets with hardware. The AWDIA listing is a hardware kit only and does not include doors.
Are frosted-glass barn doors fully private?
No. The listing describes the glass as allowing some transparency while providing a degree of privacy, so it should not be treated as fully opaque.
Why might natural-wood doors have small gaps?
The seller says the wood is fumigated before shipment and may have small gaps after installation. It also says the boards can absorb moisture and expand over time.
What should I measure before choosing a set?
Measure the opening, available wall space, ceiling clearance, and track area. Compare those measurements with panel widths, track length, and any door thickness or weight limits provided.
