Should I choose bifold doors or French doors?
Choosing between bifold doors and French doors can make a big difference to your property. Explore key considerations in our guide.

A house is like an outfit. Every element contributes to the overall vibe, from the smallest splash of colour to the most noticeable shapes and lines.
This is one reason why many homeowners agonise over interior design. The possibilities for personal expression are endless – and a little overwhelming.
Thankfully, no one has to design every feature from scratch. When it comes to large items of furniture and essential features like doors and windows, many people choose from familiar, readymade designs.
Take the case of floor-to-ceiling windows. Most homeowners choose between some kind of fixed picture window and some kind of large glass door. These doors fall into three main categories: bifold doors, French doors and sliding doors.
Even if you're unfamiliar with this terminology, chances are you can differentiate between these three classic types of doors. At its simplest, the difference lies in the way they open. Bifold doors open like a concertina, whereas French doors are split into two doors. Sliding doors, meanwhile, slide open along a rail.
It may be that one of these kinds of doors takes your fancy straight away. But if you're still unsure, there are other things to keep in mind: the cost, for one, and the access you need between the inside and outside of your property.
In this guide, we look at the differences between French doors and bi-fold doors, specifically. But before we explore the ins and outs of getting in and out, let's dive into the differences between these two stalwarts of interior design.
What are bifold doors?

A bifold door is similar to an accordion. It's made up of multiple framed glass sections connected by hinges. These fold up when closed and fold out when opened, sliding along a track.
Like any glass partition, bifold doors both separate and connect two spaces. Whether installed between indoor and outdoor areas or between large rooms, they provide a protective thermal barrier while simultaneously maximising the view.
They're often installed on patios and conservatories. They're also used to give homes a spacious, light-filled open-plan feel.
What are French doors?

Like bifold doors, French doors connect and separate indoor and outdoor spaces and provide a wide, unobstructed opening that lets plenty of light enter. The difference lies in the design.
Whereas bifold doors concertina open, French doors consist of a pair of double doors. These open from the middle. Some open inwards, some outwards and some both ways. Most of the time, these doors are covered in large glass panels with minimalist frames.
French doors are often an alternative to sliding patio doors. But why should you choose a set of French doors over their bifolding counterparts, and vice versa?
When should I choose bifold doors?
The main reason to get bifold doors is to create a large, airy space in your home. If your garden is something special, bifold doors can provide a large unbroken view.
In colder weather, bifold doors let you enjoy the chilly vistas without getting chilly yourself. And in spring and summer, you can seamlessly move in and out, bridging the gap between indoors and outdoors.
But bifold doors aren't only installed on external walls. They can also replace internal walls. If you want to combine an open-plan design with separate rooms, bifold doors are the way to go.
Then there's the question of aesthetics. Bifold doors have a sleek, contemporary look with minimalistic frames. This contrasts with the more traditional style that French doors offer.
Finally, there's the fact that bifold doors save on space. The folded panels stack neatly to the side, getting out of your way. If space is an issue, you may find these a better choice than French doors, which can swing inwards and cramp your style.
When should I choose French doors?
French doors share most of the benefits of bifold doors. So, why choose them for your home?
In our view, there are four main reasons:
- French doors have a more traditional look than bifold doors. This can make them the ideal choice for older homes – or newer homes crying out for a little vintage flair.
- French doors can be more appropriate for smaller spaces. If you want to replace an entire wall, both bifold doors and French doors can do the job nicely. But if you're working with standard door sizes, French doors are the ones to choose.
- French doors are typically cheaper to buy and install than bifold doors, thanks to their simpler construction.
- French doors are great for everyday use, operated by a simple turn of the handle. If you're regularly in and out of the garden or moving between rooms, they provide a user-friendly solution.
Why are they called "French" doors?
French doors have their origins in Italy – so why do we still call them "French"?
The answer is that this classic design took off in 17th-century France. They were designed to allow more natural light into the homes of nobles. Their combination of functionality and aesthetics soon impressed the rich in other countries, and French doors became an international sensation.
Today, French doors are like diamonds, lobsters and champagne. Once the preserve of the rich, they're now available to a much wider range of consumers.
What should you look for in a door installer?
A set of French doors or bifold doors is only as good as its installer. Work with the best and you'll have a solution that lasts. Go for second best and you'll soon be calling them back for repairs – or a costly replacement.
When shopping for these kinds of products, make sure you work with an experienced, reputable installer who can demonstrate the quality of their materials. You should also make sure your window-doors are fitted with modern multi-point locking systems for your peace of mind.
