A French door is a hinged door style that features large glass panels extending for most of its height. Usually installed in pairs, French doors open either inward or outward, bringing abundant natural light into a room while enhancing the aesthetic value of a home. They are commonly used for patios, balconies, gardens, interior dividers, and entrances.
French doors combine elegance, visibility, and functionality, making them a favorite in modern homes and luxury projects.
Why Is It Called a French Door?
The term “French door” originates from the Renaissance period in France. Inspired by Italian architecture that emphasized symmetry and light, the French adapted the concept into double-door frames filled with glass panes.
These doors allowed maximum daylight inside homes long before electricity became common.
Over time, the style spread across Europe and later to the rest of the world, becoming known globally as the French door.
Why Choose French Doors?
1. More Natural Light
The large glass panels brighten interiors and make rooms feel larger and more open.
2. Elegant Appearance
French doors have a timeless design that suits classic, modern, or luxury interiors.
3. Easy Indoor–Outdoor Connection
Perfect for patio, balcony, or garden access. They create a smooth flow between living spaces.
4. Good Ventilation
Depending on hinge type and configuration, French doors allow wide openings for fresh air.
5. Versatile Material Options
Aluminum, wood, and UPVC frames allow varying aesthetics, performance, and cost options.
6. Improved Property Value
Homes with French doors often appear more upscale, enhancing resale appeal.
What Is the Standard Size for French Doors?
While French door sizes vary by region and manufacturer, the following are common dimensions:
Standard Width
- Single door leaf: 700–900 mm (28″–36″)
- Double French doors: 1400–1800 mm (55″–71″) total width
Standard Height
- 2100 mm (82″) – most common
- 2400 mm (96″) – for modern homes with higher ceilings
- 2700 mm+ – luxury or commercial installations
Custom Sizes
French doors can be customized in width, height, glass type, and frame thickness to suit unique openings or architectural designs.
Are French Doors Easy to Break Into?
Modern French doors are much more secure than older versions.
Security Features Common Today:
- Multi-point locking system
- Tempered or laminated safety glass
- Heavy-duty hinges
- Anti-lift pins for outward-opening models
- Thick aluminum or hardwood frames
When properly installed, French doors can offer strong security comparable to other exterior door types.
What Is the Difference Between a Double Door and a French Door?
Although French doors are a type of double door, not every double door qualifies as a French door. The main difference is in the design: French doors feature large glass panels that span most of the door’s height, providing elegance and abundant natural light.
In contrast, standard double doors can take many forms—solid, paneled, or partially glazed—and do not necessarily emphasize full-length glass panels.
| Feature | French Door | Double Door |
| Design | Mostly glass panels, elegant look | More solid surface; can be glass, wood, metal |
| Light Transmission | High – designed to bring in natural light | Medium to low depending on design |
| Common Use | Patios, balconies, interior dividers | Main entrances, luxury foyers, commercial buildings |
| Appearance | Classic/European style | Varies widely (modern, traditional, industrial) |
| Operation | Hinged, opens inward/outward | Hinged, often larger and heavier |
| Purpose | Aesthetic + daylight + access | Larger entrance, statement doorway |
