Standard French Door Height: What Buyers Need to Know

What Is a French Door?

A French door is a pair of hinged doors with glass panes running most of their length. The glass is typically divided into smaller rectangular lites by muntins, though some designs use a single large pane. Unlike a standard door with a small window, the glass in a French door extends from near the top to near the bottom, allowing light to pass through while the door remains fully functional.

French doors are used both as interior doors—between rooms, onto patios, or for pantries—and as exterior entryways. The defining feature is the glass configuration, not the material. You can find French doors in wood, steel, aluminum, or fiberglass, with clear, frosted, or textured glass.

Standard French Door Height: What You Need to Know

The standard height for French doors in the North American market is 80 inches (6’8″). This is the same standard used for most residential interior and exterior doors. If you are replacing an existing door in a house built after the 1960s, the 80-inch height is almost certainly what you are working with.

For new construction or projects with higher ceilings, 96 inches (8’0″) is the most common tall option. This height is increasingly popular in modern homes with 9-foot or 10-foot ceilings, as it makes the space feel larger and allows more natural light.

There are also intermediate heights you may encounter, particularly in older homes or commercial buildings:

The rough opening height is the framed opening in the wall, not the door itself. You need roughly 1.5 to 2 inches of clearance above the door for the frame, shims, and leveling. If you are measuring an existing opening, do not assume the door height equals the opening height.

Interior vs. Exterior French Door Height

Both interior and exterior French doors typically come in the 80-inch standard. The difference is not usually in height but in construction. Exterior French doors must meet stricter requirements for weather resistance, security, and often building codes regarding egress.

If you are installing exterior French doors, check your local building code for egress requirements. In many jurisdictions, the finished opening must be at least 24 inches wide and 80 inches high for a bedroom or living area. This is not a universal rule, so verify with your local authority before ordering. A 96-inch exterior door still meets egress requirements in most cases, but the added height can complicate the rough opening if you are working with an existing header.

Can French Doors Be Custom-Sized?

Yes. Custom heights are readily available from most manufacturers, including 84-inch and 90-inch options. Custom sizing is common for:

• Remodels where the existing opening is non-standard
• Homes with unusually tall ceilings
• Commercial projects with specific design requirements
• Accessibility modifications

The trade-off with custom sizes is cost and lead time. A custom-height door typically costs 15–30% more than a standard size and may add 2–4 weeks to production. You also need to confirm that the manufacturer can produce the exact height you need—some standard door heights are limited by the glass panel sizes available.

How to Measure for French Doors

Measuring correctly is the difference between a smooth installation and a costly reorder. Here is the process:

• Measure the width at the top, middle, and bottom of the opening. Use the narrowest measurement.
• Measure the height at the left, center, and right. Use the shortest measurement.
• Check for square by measuring diagonally from corner to corner. If the two diagonal measurements differ by more than 1/4 inch, the opening is out of square.
• Account for flooring. If you are installing on a subfloor that will later receive tile, hardwood, or thick carpet, add that thickness to your height calculation. A door that fits perfectly on a subfloor will drag on finished flooring.

For a pre-hung door, the manufacturer will provide the rough opening dimensions. For a slab door (door only, no frame), you need to measure the existing frame’s interior dimensions and verify that the jamb is plumb.

French Door Styles and Configurations

French doors are not a single product but a family of configurations. The style you choose affects both appearance and price.

Full-Glass French Doors

These have glass from top to bottom with no solid panel. They maximize light and are common for patios and balconies. The glass can be a single large pane or divided into multiple lites. For exterior use, full-glass doors typically require tempered or laminated glass for safety.

Half-Glass French Doors

Half-glass doors have a solid lower panel with glass above. This style offers more privacy and is common for interior rooms where you want light without full visibility. Half-glass doors are also more energy-efficient than full-glass versions because the lower portion provides better insulation.

French Doors Without Glass

Solid-panel French doors exist, though they are less common. These look like standard double doors but retain the French door proportions and typically have panel detailing that mimics the muntin pattern of glass doors. They are used where privacy is paramount—bedrooms, bathrooms, or rooms facing a street.

French Bifold Doors with Glass

Bifold French doors fold back in sections rather than swinging on hinges. They are a good option for wide openings where swinging doors would take up too much floor space. The glass panels fold accordion-style, allowing the entire opening to clear when open.

Sliding Doors That Look Like French Doors

These are sliding glass doors with a muntin grid that mimics the look of French doors. They offer the visual appeal of French doors with the space-saving benefit of a sliding operation. This is a popular alternative for areas where a swinging door would interfere with furniture or traffic flow.

Materials: Steel, Wood, and Glass Options

The material you choose affects durability, maintenance, insulation, and price. There is no single “best” material—the right choice depends on your application and budget.

Steel French Doors

Steel French doors are common for exterior applications. They are strong, resistant to warping, and provide good security. Steel doors are typically made with a steel skin over an insulated foam core, so they offer better insulation than wood doors of similar thickness.

Steel doors are usually pre-finished with a factory-applied paint or primer. They require repainting every few years to prevent rust, especially in coastal or humid environments. Steel-and-glass French doors are a popular choice for commercial buildings and modern homes because the slim steel frame allows larger glass panels.

Wood French Doors

Wood is the traditional material for French doors. It offers natural beauty and can be stained or painted to match any interior. Common wood species include oak, mahogany, pine, and fir.

Wood requires more maintenance than steel or aluminum. Exterior wood doors need periodic refinishing to protect against moisture and UV damage. Interior wood doors are lower maintenance but can still warp in humid conditions if not properly sealed.

Aluminum and Thermal-Break Options

Aluminum French doors are lightweight, corrosion-resistant, and available in a wide range of colors through powder coating. For exterior applications in extreme climates, look for thermal-break aluminum—a design that separates the interior and exterior aluminum frames with a polyamide strip to reduce heat transfer.

Aluminum is a strong choice for large, custom-sized doors because it can span wider openings without the structural support that wood or steel would require. It is also the most recyclable option.

Glass Choices

The glass is a major cost driver. Standard clear double-pane glass is the baseline. Upgrades include:

• Low-E coatings to reduce heat transfer
• Tempered or laminated glass for safety (often required for exterior doors)
• Frosted or textured glass for privacy
• Argon gas fill between panes for better insulation
• Decorative muntins or grilles between the glass panes

For interior doors, the glass choice is mostly about aesthetics and privacy. For exterior doors, it directly affects energy costs and code compliance.

French Doors vs. Sliding Glass Doors

If you are choosing between French doors and a sliding glass door, the decision comes down to three factors: opening style, space, and cost.

Opening style. French doors swing open, which means they require clearance on both sides of the doorway. Sliding doors move along a track and require no swing clearance. In a narrow hallway or a room with furniture near the door, a sliding door is often the better fit.

Ventilation. French doors can open fully, with both leaves swinging out or in, providing a wide, unobstructed opening. Sliding doors open only halfway—one panel remains fixed. If you want maximum airflow, French doors win.

Cost. For the same size and material, sliding doors are generally less expensive because they have simpler hardware and no multi-point locking systems. French doors require hinges, handles on both leaves, and often a more complex locking mechanism.

Replacement considerations. If you are replacing an existing sliding glass door with French doors, the rough opening width is usually compatible. Sliding doors are typically 60, 72, or 96 inches wide, which matches common French door widths. However, the height might differ—some sliding doors are shorter than 80 inches. Measure carefully.

Price Range and Customization

French door prices vary widely based on size, material, glass configuration, and hardware. Here are realistic ranges to plan around:

These are material costs only. Installation, hardware, and shipping add significantly. Pre-hung doors cost more than slabs but simplify installation. Custom sizes add 15–30%. High-end hardware—multi-point locks, premium handles, concealed hinges—can add several hundred dollars per door.

For B2B buyers, the price per unit drops with volume. A project requiring 20 or more doors will command substantially better pricing than a single-door purchase. This is where working directly with a manufacturer matters—you avoid the distributor markup and can negotiate based on order size.

How to Choose the Right French Door

Use this checklist when evaluating French doors for your project:

• Confirm the rough opening dimensions. Measure width, height, and squareness. Do not order until you have exact numbers.
• Determine the height. Standard 80-inch doors work for most residential projects. Choose 96-inch for tall ceilings or a more dramatic look.
• Choose interior or exterior construction. Exterior doors need weatherstripping, proper glass ratings, and multi-point locking for security.
• Select the material based on environment. Wood for aesthetics and interior use; steel for security and exterior use; aluminum for large spans and low maintenance.
• Check local building codes. Verify egress requirements, glass safety ratings, and energy code compliance before ordering.
• Decide on glass. Consider privacy needs, light transmission, and energy performance. Frosted glass adds privacy without blocking light.
• Get a written quote with all specifications. The quote should list door height, width, material, glass type, hardware, finish, and delivery terms.
