For those considering upgrading their garden access area, sliding doors vs french doors is a common dilemma as both can brighten up a space and provide convenient access however they do differ in terms of functionality, particularly in how they open and the space they need. We’ve put together this handy guide to help you make an informed decision by comparing key considerations.
Sliding vs French Doors: How Do They Open?
The main difference between the two designs is in the way they open.
Sliding doors move horizontally along a track with the two panels moving past one another. They don’t open out into the room or onto the patio however the panels do overlap when open limiting how much of the doorway is clear.
French doors on the other hand consist of two hinged panels that open inward or outward depending on the design and provide a wider passage as long as there’s enough space for them to swing.
Sliding Doors vs French Doors: Key Features Comparison
Space and Opening Width
One of the factors that can help you make a decision between the two designs is what sits around your garden entrance. Sliding doors leave more space for furniture or patio seating for example while hinged designs will need a clear opening area on the side they swing towards, so what’s currently sitting in the area or what you’re planning to place there will be an important consideration.
It’s also worth thinking about the available passage width as for the same overall frame width, hinged designs typically provide a wider available passage when both panels are open.
Aesthetics, Natural Light and Views
Sliding designs are perfect for contemporary homes as they offer a cleaner, more modern look while hinged options create a lovely symmetry that can suit both modern and traditional properties depending on the finish.
For the same-sized opening however neither provides more or less natural light or a clearer view when closed since both have central framing, so you should compare the actual frame widths and glass area as slimmer frames allow for a bigger part of the garden to be visible.
The clearer difference is mainly noticed when they’re open as French doors leave the view unobstructed while with sliding designs, the panels will remain across part of the opening.
Cost and Installation
When it comes to the cost of french doors vs sliding doors, french can often be a more affordable option particularly when comparing a standard uPVC pair with a large aluminium sliding system, however for the same-sized opening costs will depend on frame material, glazing, hardware, etc.
The work involved is also a huge factor as replacing a set with a new one with the same opening will usually cost less than widening the entrance. An experienced installer like us at RB Windows can provide you with quotes for both options depending on your existing opening and talk you through the best options for you based on budget and space.

Energy Efficiency and Security
Neither option is necessarily more energy efficient or secure. If you’re looking to improve energy efficiency, look at the U-values of the whole system, as a lower number means less heat will pass through the unit. The glazing type, how the frame is constructed and your weather seals will all contribute so it’s worth considering them when thinking about energy efficiency rather than just the appearance.
For security, french doors need to secure both opening leaves while sliding systems typically include protections that prevent panels being lifted from their tracks.
Cleaning and Maintenance
Both styles need their frames and glass cleaned regularly, the difference being the particular parts that need more attention. For sliding doors, since they rely on sliding along tracks, maintaining the tracks and rollers clean is key while for hinged designs, hinges and locks need to be regularly checked for stiffness / misalignment.
The material you choose for either of those designs will also matter a lot when it comes to upkeep as timber for example may need to be refinished periodically, while uPVC and aluminium in general need less attention.
Thresholds and Accessibility
French doors leave a wider passage (when both leaves are open) while a sliding design will keep the way clear of swinging panels. For someone using a wheelchair for example the decision between the two will involve balancing the available passage width with the space needed to independently manoeuvre the entrance.
Neither style automatically comes with a lower threshold so it’s worth asking your installer to specifically offer low-threshold options if this is a concern.
Should You Choose Sliding or French Doors for Your Home?
The choice between sliding doors vs french doors will depend on the space you have available, how your space is styled and what matters most to you.
Consider Sliding Doors If:
- Space is limited around your entrance and you want to avoid swinging panels
- You have a wide opening and prefer large glass panes
- You want flexibility to position furniture / patio seating nearby and keep the access route clear
- You enjoy a contemporary aesthetic
Consider French Doors If:
- You have enough room for the leaves to swing open
- You want to maximise the clear passage available within a smaller opening
- You like a symmetrical appearance
- You want the option of opening one leaf for daily use or both when needed
