Sliding Patio Doors vs. French Doors
A sliding patio door glides along a track and takes up no floor space when it opens. French doors swing open on hinges and give a wider, more traditional opening. The right choice depends mostly on space and how you use the doorway.
Side by side
| Sliding door | French doors | |
|---|---|---|
| Typical installed cost | $1,169–$4,148 (about $2,565 average) | $2,000–$5,000 (about $3,500 average) |
| Opening | About half the door width | Full width when both doors open |
| Space needed | None; slides in its own frame | Clear swing space inside or outside |
| Furniture placement | Easy; nothing swings | Must keep the swing path clear |
| Maintenance | Clean and lubricate the track and rollers | Adjust hinges; check weatherstripping where doors meet |
| Security | Add a secondary lock or bar | Multipoint locks available |
| Look | Large, uninterrupted glass | Traditional; divided-lite options |

Installation changes
Swapping one style for the other in the same opening is common, but sizes do not always match. A wider opening means new framing and a properly sized header, plus trim and siding work outside. Cutting a brand-new opening runs $1,000–$3,600 before the door itself.
Which fits
- Sliding: small rooms, decks with furniture near the door, or when you want maximum glass and light.
- French doors: you want a wide opening for entertaining, have swing space, and prefer a traditional look.
- Hinged patio door (one fixed, one operating): a middle ground with a French look but less swing space.
