French doors are a timeless, elegant choice that can transform the look and feel of your home's entryway. Whether you're updating a patio entrance or upgrading your front facade, choosing a French door means balancing style, function, and practicality. 

At doors.com, you’ll find a curated selection of high-quality French front doors available in wood, fiberglass, and iron—all designed to enhance natural light, improve curb appeal, and elevate your space.

Before you make your purchase, it’s important to understand the key factors involved in choosing a French door—from sizing and materials to security and style. Use this guide to make an informed decision that suits your home’s architecture and your personal needs.

7 Factors to Consider Before Buying a French Door

Here’s an expanded version of your French door buying guide, tailored specifically for doors.com and focused solely on products available through the site:

1. Door Size and Measurements

Getting the right size is one of the most critical steps when choosing a French door. On doors.com, French doors come in a variety of standard and customizable widths, generally ranging from 48 inches (4 ft) to 72 inches (6 ft), and most are 80 inches (6 ft 8 in) tall. 

Before ordering, take precise measurements of your current door opening—height, width, and wall depth. Also, consider whether you need a pre-hung unit or a slab-only door if you’re retrofitting. If your entryway is non-standard, doors.com offers custom size options on many wood and iron French doors to ensure a perfect fit.

2. Material Selection

The material of your French door impacts its durability, energy efficiency, and aesthetic. At doors.com, French doors are primarily offered in the following materials:

Wood

Ideal for traditional and rustic homes, wood French doors offer timeless beauty and natural warmth. Choose from premium species like mahogany, knotty alder, and Douglas fir. Many models on doors.com come prefinished or ready to stain/paint.

Fiberglass

A great low-maintenance alternative to wood, fiberglass mimics woodgrain textures while offering better insulation and weather resistance. It’s also less prone to warping and cracking, making it ideal for varying climates.

Iron

For maximum durability and security with a dramatic look, iron French doors are unmatched. Doors.com carries handcrafted iron models with arched tops, scrollwork, and clear or frosted glass.

3. Glazing Options

French doors are defined by their glass panels, so glazing is an essential factor to consider:

Double or Triple Glazing

Available on most models at doors.com, these multi-pane constructions offer better insulation and noise reduction. Great for both hot and cold climates.

Low-E Coated Glass

Found in energy-efficient models, this special coating reflects infrared heat while allowing natural light to pass through, helping keep interiors comfortable year-round.

Tempered or Laminated Safety Glass

Most French doors on doors.com feature safety-rated glass that resists shattering, improving security and reducing injury risks.

4. Security Features

Security is often a concern with French doors due to the amount of glass involved. Fortunately, modern models on doors.com are designed with robust protection in mind:

Multi-Point Locking Systems

Many double French doors now come equipped with multi-point locks that secure the door at the top, middle, and bottom for superior strength.

Reinforced Frames & Hinges

Reinforced hardwood or steel frames and heavy-duty hinges prevent forced entry and sagging over time.

Impact-Resistant Glass

Select models come with impact-rated glass, ideal for hurricane-prone or high-risk areas.

5. Swing Direction and Space Considerations

When choosing a French door, consider how it will open and how much space you have available:

In-Swing Doors

These open into the interior space and are common for front or patio entries. Ensure you have enough clearance inside the home.

Out-Swing Doors 

Ideal for saving space indoors or enhancing security (harder to force open). Be sure your porch or patio allows for unobstructed outward movement.

Doors.com lists the swing direction on each product page, making it easy to choose the right option.

6. Aesthetic and Design Choices

French doors should complement your home’s architectural style. At doors.com, you’ll find designs ranging from traditional to ultra-modern:

Grille Styles

Choose from full-view, divided-lite, or decorative wrought iron grille inserts. These details can match Craftsman, Mediterranean, or Farmhouse exteriors.

Arched or Square Tops

Many wood and iron French doors are available with arched tops for a softer, elegant silhouette.

Finishes and Textures

Whether you want a prefinished wood grain or a sleek matte black iron frame, doors.com offers a variety of finishes and textures to personalize your selection.

7. Budget and Installation Costs

French doors range widely in price depending on size, material, and finish:

Wood Models

Higher-end species like mahogany cost more but offer unmatched elegance. Expect to invest more in custom or arched models.

Fiberglass & Iron Options

Fiberglass doors offer great value, while iron options are pricier due to their construction and weight, but deliver top-tier security and durability.

Installation Costs

Professional installation is recommended for proper sealing, frame alignment, and long-term performance, especially for larger double doors. Doors.com sells pre-hung systems to simplify the process.
