FAQs

Q: How do I work out which bi-fold door size I need?

A: Measure the width and height of your door opening, allowing for a fitting tolerance of around half an inch. We recommend hiring a professional to take precise measurements.

Q: What size of opening do bi-fold doors fit?

A: Standard bi-fold doors come in predefined sizes, but Origin’s custom-made bi-folds can fit almost any opening, with specific minimum and maximum size requirements.

Q: What is the minimum width and height for bi-fold doors?

A: The minimum width of an individual door panel is 15.75 inches (for odd-numbered configurations) and 28 inches (for even-numbered configurations). The minimum full door set width is approximately 48 inches, and the minimum height is 15.75 inches.

Q: What is the maximum width and height for bi-fold doors?

A: Each individual door panel can be up to 48 inches wide, while the full door set can extend up to approximately 65 feet with multiple panels. The maximum height for standard configurations is around 118 inches.

Q: What are the standard bi-fold door sizes?

A: Standard three-door bi-folds typically range between 70–96 inches in width and 80–96 inches in height. However, all Origin doors are custom-made to fit your specific requirements.

Q: How many panels do I need?

A: The number of panels depends on your available space. While there’s no real maximum, doors larger than 20 feet often require a dual-track system. Custom panel sizes can be adjusted accordingly.

Q: How thin are the door frames?

A: Aluminium bi-fold doors have the slimmest frames, with Origin’s OB49 offering a sash width of just 2.8 inches for a sleek and modern look.

Q: Which way do the doors fold?

A: You can configure your doors to fold left, right, or split in both directions. The lead door, which contains the multi-point locking system, is positioned based on your preferred layout.

Q: Do bi-fold doors open inwards or outwards?

A: Origin bi-fold doors can be configured to open either inwards or outwards, depending on your space and preference. Outward-opening doors are ideal for maximizing interior space.
