Bifold Door Sizes: Which Size Do You Need?
Bifold doors, both internal and external, are a beautiful way of allowing more natural light to flood into your home. Made from a series of glass panels that fold neatly back into themselves, bifold doors create a stunning and stylish focal point while making the most of the surrounding space.
Bifold doors come in a variety of sizes, and it’s essential that you buy the right-sized door. So which size is right for your home? This blog will explore the standard sizes available to you and how to determine which size you need.
What Are the Standard Bifold Door Sizes in the UK?
Internal Bifold Door Sizes
The average height for an internal bifold door in the UK is 2,074mm or 6.8ft. The width of the door will depend on the size and shape of the opening. The width will then determine the number of panels your bifold door has. Standard widths for internal bifold doors include:
| Metres | Feet | Millimetres |
|---|---|---|
| 1.2 | 4 | 1,200 |
| 1.5 | 5 | 1,500 |
| 1.8 | 6 | 1,800 |
| 2.1 | 7 | 2,100 |
| 2.4 | 8 | 2,400 |
| 2.7 | 9 | 2,700 |
| 3.0 | 10 | 3,000 |
| 3.6 | 12 | 3,600 |
External Bifold Door Sizes
The average height of an external bifold door in the UK is 2,090mm or 6.10ft. Again, the width will depend on the size of your room and the opening, but standard UK width sizes include:
| Metres | Feet | Millimetres |
|---|---|---|
| 1.8 | 6 | 1,800 |
| 2.1 | 7 | 2,100 |
| 2.4 | 8 | 2,400 |
| 2.7 | 9 | 2,700 |

How to measure bifold doors
If you're ordering your own bifold doors or would like a measurement for an accurate quote, here's how:
- Measure the diagonals of the opening from corner to corner to make sure the opening is level.
- Measure the height of the opening at the left-hand side, the right-hand side, and the middle.
- Measure the width of the opening at the top, middle, and bottom.
- Take the smallest height and width measurements and subtract 10mm from each measurement to allow for the fitting tolerance. This is the size of the door you need to order.
Custom Bifold Door Sizes
You may find that a standard-sized bifold door is not appropriate for your home. If you have an older home, a particularly large opening, or an awkwardly shaped room, made-to-measure bifold doors may be a good option.
Custom-made bifold doors will ensure your doors fit perfectly, maximising not only performance but also aesthetics. It is worth bearing in mind that custom bifold doors will be more expensive than standard off-the-shelf options and have longer lead times, but they will offer greater flexibility in terms of choice of materials and glazing.
Which Size Bifold Door Do You Need
There are a few factors you need to consider before deciding on which bifold door is right for you.
- Firstly, what is your new bifold door for? An internal dividing door? An external patio door? The use will determine what type of door you choose in terms of materials.
- Measure the opening accurately. The size of the door will have an impact on the type of door you can have. For example, if the opening is large, an aluminium bifold door, which can provide additional structural support, may be more suitable.
- Think carefully about the aesthetic you want to achieve. For example, if you have a 2,400mm opening, you could choose either three 800mm glass panels or four 600mm panels, each offering a different dynamic in terms of visual finish.
- Which material would you like your bifold door to be made from? For example, uPVC is a popular option, which is both long-lasting and available in several different colours. As mentioned above, if you have a larger opening, aluminium will be the best option.
Regardless of where your new bifold door is located, we would always recommend consulting an expert before purchasing your new doors. They will be able to advise and guide you towards the best option for you and your home.
