Plan the path first Before placing furniture, keep a 30 to 36 in-wide route from the room’s entry to the opening half of the door, and a 36 in-deep landing in front of it. A sofa can sit in front of the fixed half of a slider. It can’t sit inside a French door’s swing: a 72 in pair of in-swing doors needs a 72 × 36 in patch of floor kept empty.
Patio doors are the best thing in a small living room and the hardest thing to furnish around. They bring in more light than any window, and they also turn one wall into a doorway that people need to reach, open and walk through.
The fix is to treat the door as a destination, like a hallway, and plan its path before anything else. It’s hardest in a narrow room, 10 ft wide or less, where the path to the door and the TV wall compete for the same strip of floor. Here’s how much floor each type of patio door needs inside the room, and three measured layouts, checked in our living room layout planner.
How much floor each patio door needs
| Door | Common widths | Floor it needs inside |
|---|---|---|
| Two-panel slider | 60 in, 72 in, 96 in | A 36 in landing in front of the moving panel |
| Three-panel slider | 108 in, 144 in | A landing in front of each moving panel |
| French doors, swinging in | 60 in (two 30 in leaves), 72 in (two 36 in leaves) | The full swing of both leaves, plus the landing |
| French doors, swinging out | Same widths | The landing only |
Standard slider heights are 80 to 96 in. The landing and path widths are our planning numbers, based on the 30 to 36 in walkways designers recommend.
Only one panel of a two-panel slider moves, so a 72 in slider opens to roughly half its width. That half is the only part of the wall that needs a clear landing. The fixed half can sit behind a low sofa, a chair or a plant without blocking anything.
Two layouts for a small living room with a slider
Narrow room, slider on the short wall
Fits 10 ft × 14 ft with a 12 in console
- A 36 in-deep landing in front of the whole slider
- A 30 in path from the entry door to the landing
- Across the 10 ft width: 4 in behind the sofa + 34 in sofa + 16 in + 24 in table + 30 in path + 12 in TV console = 120 in
- Seated eyes are about 94 in (7 ft 10 in) from the screen, so a 58 to 79 in TV fills 30–40° of view
- 16 in from the sofa to the coffee table
Best for: long, narrow rooms where the doors are at the far end.
The trade-off: the path runs between the coffee table and the TV, so people walk through the view, and it only works with a shallow console pushed to the wall. With the 16 in console our planner assumes, the path drops to about 25 in, which passes only at minimum clearances. A console 10 in deep or less, or a room 10 ft 6 in wide, passes at standard.
Sofa facing a slider on the long wall
Fits 14 ft × 10 ft, planner-checked
- Sofa on the wall opposite the doors, facing the view
- A 36 in walkway along the door side, the full length of the room: 4 + 34 + 16 + 24 + 6 spare + 36 = 120 in
- 16 in to a 48 × 24 in coffee table
- An accent chair at the end, angled toward both the sofa and the view
Best for: rooms where the doors are on a long wall and the view is the focal point.
The trade-off: there’s no natural TV wall. Use an end wall with a swivel mount, or accept that this room is for talking and reading.
French doors that swing in
Keep the arcs empty
- Each leaf sweeps an arc as deep as the leaf is wide: 30 in for a 60 in pair, 36 in for a 72 in pair
- Nothing can sit in the arcs, not even a rug that catches the door
- Seating goes beside the doors or beyond the arcs, not in front
- Out-swing doors free this floor if you’re replacing them
Best for: rooms that need the full opening, for parties or for moving furniture in and out. Check big pieces with Will It Fit Through the Door first.
The trade-off: a 72 in pair claims a 72 × 36 in strip of floor: 2,592 sq in, or 18 sq ft, that you can’t furnish. The two arcs alone are about 14 sq ft (2 × ¼ × π × 36²). A slider of the same width gives most of that back.
Leave wall beside the door for curtains. Open curtains stack on the wall beside the door; without that wall they cover part of the opening. The Curtain Calculator sizes the rod, including 8 to 12 in past each side to clear the glass.
Stop the rug short of the door’s path so the door and feet don’t catch it. The Rug Size Calculator works out what fits.
The clearances we checked
These are the numbers behind every layout on this page. Where three values are shown, they are the minimum, standard and roomy settings the living room layout planner uses.
- The door’s overall width, and which panel slides or which way the leaves swing.
- The wall space beside the door, where curtains or blinds will stack.
- The route from the room’s entry to the opening side of the door.
- Any step, threshold or rug edge in front of the door.
Questions
Can a sofa go in front of a sliding glass door?
In front of the fixed panel, yes, if its back is low. Never in front of the panel that moves: that half needs a clear landing about 36 in deep.
How much space do you need in front of a patio door?
Plan on a 36 in-deep landing in front of the opening, connected to the room’s entry by a 30 to 36 in path. For in-swing French doors, add the full swing of each leaf.
Sliding or French doors for a small living room?
Sliding doors need no swing space, so they’re easier to furnish around. French doors give a wider opening; choose out-swing models if you can.
How do you lay out a narrow living room with patio doors?
Put the sofa and TV on the two long walls and keep a 30 in path down one side to the doors. In a 10 ft-wide room that only fits with a TV console 12 in deep or less: 4 + 34 + 16 + 24 + 30 + 12 = 120 in.
Where does the TV go in a room with patio doors?
On a solid wall facing or beside the seating, never on the glass wall. If the doors are on the long wall, an end wall with a swivel mount is often the only option.
