French Doors Opening Inwards or Outwards: Plan the Space First

French doors opening inwards or outwards look almost identical when they’re closed. Open them, though, and they behave very differently. One arrangement swings into your room, the other swings out over the patio, and that single choice affects where the dining table can go, how the curtains hang, and whether anyone can walk past while the doors are moving.

If you’re planning new French doors for a home in Newcastle-under-Lyme or elsewhere in North Staffordshire, the right answer comes from your actual room and garden, not from a brochure photo. This guide covers what to measure, what to decide, and what to put on the order.

We fit French doors with inward and outward opening options, so the direction is a genuine choice for your home.

Draw the space each door needs

Every hinged door leaf sweeps an arc as it opens, and that arc needs to stay clear. A room can feel generous with the doors shut, then suddenly cramped when a leaf meets the dining table, a radiator, a curtain, or the end of a kitchen run.

The easiest way to check is to sketch the room from above. Draw the doorway, the two leaves, the direction they’ll open, and the furniture you’re actually keeping. Add the handles too, because they stick out further than the glass and are often what catches first.

Then do the same outside. Mark the patio edge, any steps, raised beds, pots, and the path to the side gate. An outward-opening leaf might sit neatly against the wall once open, yet still block someone walking past while it swings.

Your sketch is a starting point for the conversation, not the final word. Hinge position, frame design, and how far each leaf can open all vary between systems, so the actual geometry is confirmed at the survey.

When outward opening works well

Outward opening keeps the moving leaves out of the room. That’s a real help when a dining table, sofa, or kitchen island needs to sit close to the doors. It does need suitable space outside, though, and it isn’t a good idea where a leaf would swing across a narrow shared path or over a sudden change in level.

If your patio is generous and level, outward opening is often the simpler choice, and the doors can sit back against the wall on a warm day.

When inward opening makes more sense

Inward opening suits homes where the outside space is tight, such as a narrow side return or a patio that drops away quickly. The clearance then moves indoors. Curtains, rugs, and nearby furniture all need to let the leaves move freely, and you’ll want somewhere for wet boots that isn’t right in the door’s path.

Neither direction is automatically the more accessible one. Someone using a walking aid needs room to approach, reach the handle, and step back from the opening leaf. A wide pair of doors can still be awkward if the leaf you use every day is narrow or the handle is hard to reach.

If both directions cause a problem, it may be worth looking at a different type of door altogether. Our sliding patio doors open without a swing, although their clear opening and threshold still need checking.

For a wider view, our comparison of bifold, sliding, and French doors sets out how each type connects a room with the garden.

Decide which leaf you’ll use every day

French doors usually have one leaf that opens first, often called the active leaf. The second leaf is released when you want the full width, for moving furniture or opening up in summer. Choosing which side is active is worth doing early, while the room layout is still being planned.

“The left one” sounds clear, but it depends on where you’re standing. Left from inside is right from the garden. The simplest fix is a drawing that states the viewing direction and marks the active leaf, kept with the signed specification so everyone works from the same reference.

Think about your routine: carrying washing out, letting the dog into the garden, or coming back with shopping. The best everyday leaf usually lines up with the clearest route, with a handle that’s easy to reach once the furniture is in place.

Also check what happens when you open both leaves. Ask for the clear opening with both doors open, rather than relying on the overall frame size.

Plan the threshold and outside levels together

A low threshold can reduce the step at the doorway, but “low” doesn’t mean completely level, and it isn’t right for every situation. The inside floor, the door frame, the outside paving, and the drainage all have to work together, so the threshold is best decided at the survey rather than picked from a list.

Our guide to low threshold doors explains the options in more detail.

The government’s Approved Document M guidance covers access to and use of buildings in England. Which parts apply depends on the work and the building, so the right detail for your doorway is something your installer, and building control where relevant, should confirm.

Tell us about any planned changes before the survey. A new raised deck outside, or a thicker floor finish such as tiles over underfloor heating, can change how the finished levels meet the door.

Rainwater needs somewhere to go too, and a doorway that feels sheltered on a calm day can behave very differently in wind-driven rain, so talk through drainage and exposure at the survey.

Glass, hardware, and safe everyday use

Large glazed leaves need the right safety glass, whichever way they open. The government’s Approved Document K guidance covers protection from collision and impact, including glazing in doors, and forms part of the design considerations in England.

On a breezy day an open leaf can swing back sharply. Door restraints or suitable hold-open arrangements help keep the doors under control, as long as they’re compatible with the system and fitted properly. A doorstop or plant pot isn’t a substitute.

Security is about the complete doorset: frame, hinges, locks, and glass together. Ask about the security features and any certification for the actual product you’re being quoted. Outward-opening doors have their hinges on the outside, so ask how the chosen system protects them rather than judging on hinge position alone.

At handover, ask to see the order the leaves close in and how the locks engage. If the doors ever feel stiff, get in touch rather than forcing the handle.

What to bring to your survey

Bring a rough plan showing nearby furniture, planned floor finishes, and outside features, and mention any mobility needs in the household and how often you expect to open both leaves.

The final specification should then set out the opening direction, active leaf, clear opening, frame colour, glass, threshold, and hardware, plus any making good to the surrounding walls or floor. That level of detail is far easier to check than a line that simply says “white French doors”.
