Bi-fold door size and configuration FAQs

What is the opening size for a bi-fold door?

All of our doors are custom made, so we can manufacture them to fit almost any size. The minimum height is 15¾” and the maximum height is 96”. In terms of the overall width of the door set, they can be manufactured from 48” to well over 30 feet.

To see different openings for different sizes view the table at the bottom of this page.

What is the minimum size for bi-fold doors?

The minimum height of an Origin Bi-fold Door is 15¾”and the minimum width of a three-door bi-fold is 47”.

What is the standard height for bi-fold doors?

The standard height of a bi-fold door is usually between 80” and 96”. However, we do manufacture doors any size between 15¾” and 96”.

What is the maximum width for bi-fold doors?

The maximum width of one Origin Bi-fold Door panel is 48”. However, many panels can be used to fit into large openings.

Can bi-fold doors open inwards?

Yes. Bi-fold doors can be configured to open inwards or outwards, depending on your preference. What this means is when the doors are folded back, the panels will either sit inside your home or open outwards onto your outdoor space. If you have limited internal space but lots of outdoor space, then it’s recommended to opt for an outward opening.

How thin are the door frames?

The frames on Origin Doors are slim because we use high-strength aluminum. The doors have been engineered to achieve the thinnest possible frame to maximize the view through the doors while maintaining strength and security.

How big is each individual panel?

Panels are available in different sizes. Our maximum size panel is 1200mm (47 inches) wide x 2500mm (98 inches) high. Our smallest panels are 400mm wide for an odd number of doors or 700m for an even number of doors.

How many panels do I need?

The number of panels you need depends on the space you are fitting the doors into. There are few limitations to the number of panels you have – the minimum is two and the maximum is eight. More panels can be accommodated but will need another track. Since panels are available in custom sizes, dimensions can be adjusted to ensure you can have the number of panels you want.

What size of bi-fold doors do I need and how do I measure my space for new bi-folds?

To decide on the size of bi-fold you need, you must assess the space. The space created, known as the aperture, will need to allow some room for fitting, so when you measure up, the actual size of door ordered will be the aperture available minus room for fitting.

To ensure you order the right size we recommend you seek help from a professional to take the measurements. They will help you decide how much of the wall you want to be taken up with bi-fold doors (whether you want the wall to be almost completely replaced by doors) or whether you would prefer some wall space around the door.

 However, if you want to get an initial sense of the size you will need you need to take measurements of a potential aperture. To take the measurements:

  • Measure the width at 3 separate levels and use the smallest width for your order.
  • Measure the diagonals from corner to corner, and check that the area is a perfect square.

Which way will the doors open?

There are various configurations available for your door, and you can choose whether your doors open in or out, left or right, or if some of your doors will go to the left and some will go to the right. For example, if you have a set of five panels, you might choose to have two panels sliding left and three sliding right. Alternatively, you might want them all to slide the same way.

The configuration affects where the lead door is placed. This is the panel that opens first and contains the multipoint locking system. If you pick a configuration that slides two panels left and three panels right, the lead door will sit in the middle of the entire system. If the doors all slide one way then the lead panel will sit either on the left or the right.

Can I have custom sizes?

Yes, all our bi-fold doors are made to measure, and can fit unusual spaces. We are flexible in our approach, so even if you think you might need doors that exceed our maximum or minimum sizes then get in touch and we can discuss different options to help you achieve the look and finish that you desire.
