Ask for “French doors” at a window and door showroom in Ontario and there’s a good chance what you’ll be shown is actually a garden door. The two look nearly identical closed, but they work differently, cost differently, and suit different rooms. Here’s the full explanation of what a garden door is and when it’s the right call.
What a Garden Door Is
A garden door is a two-panel exterior door in one frame where one panel is fixed and the other is hinged and swings like a regular entry door. From outside it looks like a pair of French doors. From a function standpoint, it’s a wide single door with a big fixed sidelite. The panels are usually glass from top to bottom, often with internal grilles, and the fixed panel can typically be unlocked and opened by a tradesperson to move furniture through.
Garden Door vs. French Door
| Factor | Garden door | French doors |
|---|---|---|
| Operable panels | One | Two |
| Clear opening | About half the width (30″ typical) | Full width (60″ typical) |
| Swing clearance needed | One panel’s worth | Two panels’ worth |
| Air and water seal | Excellent; only one moving panel and no centre astragal gap | Very good; the meeting point of two doors is the weak spot |
| Screen | Sliding or hinged screen fits easily | Retractable or double screens |
| Security | Standard deadbolt plus multi-point available | Needs flush bolts on the inactive door plus a deadbolt |
| Cost | Lower | Higher |
The seal difference is real. Two French doors meet in the middle at an astragal, and that joint is where wind, water, and drafts find their way in as the doors settle. A garden door has no meeting joint; the fixed panel is sealed like a window.
Garden Door vs. Sliding Door
Both give you roughly a half-width opening. The slider has no swing, a wider view, and usually costs a bit less. The garden door seals better, looks more traditional, and has a proper hinged door’s feel and hardware. If you’ve had a slider that iced up in its track or got hard to move, a garden door fixes both problems; if you’re tight on deck or floor space, the slider wins.
Configurations and Sizes
- Standard widths: 5 feet (two 30-inch panels) and 6 feet (two 36-inch panels), sized to replace a standard slider opening.
- Handing: the operable panel can be left or right, and the swing can be in or out. Out-swing seals better against wind and rain but exposes the hinges (specify security hinges); in-swing is common where a storm door or a step is outside.
- Sidelites and transoms: available for wider or taller openings.
- Mini-blind or grille options: internal blinds between the panes are popular for privacy on a garden door’s fixed panel.

Materials, Glass, and Hardware
Garden doors come in steel and fibreglass, the same choice as an entry door (see our steel vs. fibreglass guide). Because the panels are mostly glass, the glass package does the energy work: Low-E, argon, and a warm-edge spacer at minimum, triple glazing if the door faces north or a windy exposure. Tempered glass is mandatory in any door. Hardware ranges from a standard lever and deadbolt to a multi-point lock that engages at three places on the operable panel; on a door this size, multi-point is worth it for both security and long-term seal.
Pros and Cons
Pros
French-door look at lower cost. Best seal of the three patio door types. Screen fits easily. Half the swing clearance of French doors. No track to ice up. Fixed panel opens for large furniture.
Cons
Only half the opening for daily use. Still needs some swing room. Less glass area than a slider of the same width. Not the full French-door experience if that’s what you love.
Cost in Ontario
Installed 2026 pricing for a 5- or 6-foot garden door in Ontario generally runs $2,500 to $5,000, with steel at the low end, fibreglass and multi-point hardware at the high end, and the GTA 10 to 20 percent above the rest of the province. That’s typically a few hundred dollars more than a comparable slider and several hundred to a thousand less than true French doors. If replacing a slider, the rough opening is usually the same size, which keeps installation straightforward.
Who Should Choose One
A garden door is the right choice if you want the look of French doors on a small deck or beside a dining table, if you’ve had a draughty or icy slider and want a door that seals like a front door, or if you want a screen without the complications of double doors. Choose true French doors only when you have the room and want the full opening; choose a slider when swing space is zero.
