Thinking about installing French doors, but not sure what width you need? You’re not alone! The width of French doors is a key factor that impacts everything from the flow of natural light to how easily you can move furniture in and out.

Choosing the right size is crucial for both style and function. In this article, we’ll break down standard French door widths, factors that influence your choice, and tips for measuring your space with confidence.

Understanding French Door Width: The Complete Guide

French doors add elegance and function to homes, creating open, light-filled spaces while maintaining classic style. If you’re thinking about installing these beautiful double doors, it’s crucial to understand their standard and custom width options, the impact on your space, and the best ways to measure for a perfect fit. Let’s dive into everything you need to know about French door widths!


What Is the Standard Width of a French Door?

Before choosing a French door, you need to know their typical width ranges. The “width” usually refers to the total measurement from one edge of a single door panel to the other (including both doors), not just one leaf. Here’s what you can expect:

Common French Door Widths

French doors come in several standard widths to suit most homes:

  • Usual overall widths (both doors together):
  • 48 inches (two 24-inch doors)
  • 60 inches (two 30-inch doors)
  • 72 inches (two 36-inch doors)
  • 96 inches (two 48-inch doors, less common)

  • Single door width for each panel:

  • Ranges from 24 to 36 inches

Most often, you’ll find pairs of French doors that are either 60 or 72 inches wide in total. The doors are evenly split, meaning a 72-inch set features two 36-inch doors.

Custom Options

If your opening is non-standard, manufacturers often offer custom widths and heights. While most people stick to the common sizes above for convenience and cost, custom sizing is available for unique spaces or historical homes.


Why French Door Width Matters

Selecting the right width for your French doors does more than just fit the hole in your wall. The width impacts:

  • Traffic flow: Wider doors allow easier movement of people and large furniture.
  • Aesthetics: Wide doors make a dramatic architectural statement and let in more light.
  • Furniture placement: Narrower doors might work better in smaller rooms.
  • Energy efficiency: Door width can affect insulation and drafts if not sized properly.

Careful planning ensures function and style go hand-in-hand.


How to Measure for French Doors

To ensure your new French doors fit precisely, follow this simple step-by-step process:

  1. Measure the rough opening width:
  2. Use a tape measure to determine the space from one side of the frame to the other, at the widest point.
  3. Measure at the top, middle, and bottom, as frames can be uneven.
  4. Select your door size:
  5. Standard French door units are typically 1 to 2 inches narrower than the rough opening (to allow space for the frame and adjustments).
  6. For a 60-inch opening, you might choose a 58- or 59-inch door unit.
  7. Check for level and plumb:
  8. Walls and floors can shift over time. Ensuring your opening is level prevents installation headaches.
  9. Account for the frame:
  10. Remember, the “door size” is typically just the doors—add a little extra space for the jambs and threshold if present.

Tips for Replacing Existing Doors

  • Remove trim to access the raw opening before measuring.
  • If upgrading from a single to French doors, consult a structural professional; you may need to widen the opening.

Benefits of Choosing the Right French Door Width

Picking the ideal French door width for your space brings many advantages:

  • Enhanced room connection:
    Wide French doors unite indoor and outdoor areas or two rooms within your house.
  • Natural light:
    More glass surface means you’ll enjoy brighter, airier environments.
  • Improved ventilation:
    A broader opening brings in more fresh air on nice days.

Challenges and Considerations When Sizing French Doors

There are a few things to keep in mind as you choose your door width:

  • Wall space:
    Make sure you have enough clear wall on either side for the doors to swing open.
  • Furniture layout:
    Don’t block the doorway with large pieces.
  • Door swing:
    French doors usually swing in or out—measure swing clearance carefully.
  • Installation limitations:
    Wide doors may require modifications to the wall frame or header for proper support.

Practical Tips for Selecting French Door Width

Here are some practical, field-tested suggestions to guide your choice:

  • Match your opening size, not just the “wall hole”:
    The rough opening is your guide—door sets are usually 2 inches smaller in width and height due to frames.
  • Balance looks and use:
    In small rooms, 48-inch (two 24-inch doors) sets might maximize space. For open-plan layouts or patios, consider 60- to 72-inch sets.
  • Opt for wider doors for entertaining:
    Wide doors make it easy to move large items or welcome many guests at once.
  • Keep weather in mind for exteriors:
    Exterior French doors should seal tightly; wider sets may need more robust weatherstripping.

Best Practices for Ordering and Installing French Doors

When you’re ready to buy or install, follow these best practices:

  1. Measure more than once:
  2. Double-check all measurements, including height and width.
  3. Consider the swing direction:
  4. Decide whether you need the doors to open inwards or outwards based on space and safety.
  5. Choose the right jamb style:
  6. Pre-hung sets include frames; slab doors do not. Pre-hung units help with alignment, especially for wide doors.
  7. Inspect delivery before accepting:
  8. Ensure there is no damage or warping in shipment.
  9. Use professional help if needed:
  10. Wide or heavy doors are best installed with assistance to prevent misalignment.

Cost Considerations: Getting Value for Your Money

The width of your French doors influences cost, from the doors themselves to shipping and installation. Here’s what to consider:

  • Material costs:
  • Wider doors mean more material—expect a price jump for each foot of added width.
  • Popular materials include wood, fiberglass, and metal-clad options.
  • Standard vs. custom sizing:
  • Standard widths often cost less and ship faster.
  • Custom doors mean extra expense, longer wait times, and additional care in measuring.
  • Shipping:
  • Bulkier doors are heavier and harder to transport—factor in increased delivery fees.
  • Installation:
  • Labor charges may rise for extra-wide or heavy French doors needing two installers.
  • Energy efficiency:
  • Wider glass areas can impact insulation; invest in multi-pane, low-E glass for savings long term.

Tips for Saving on Costs

  • Stick to standard sizes where possible to avoid extra custom fees.
  • Look for seasonal sales or bundled deals at local suppliers and home improvement centers.
  • Check return policies in case of sizing errors—especially important for custom orders.
  • Compare installation quotes if you’re not DIY-inclined.

Summary

Choosing the right width for your French doors can transform your space, letting in light, expanding access, and blending style with function. Standard widths range from 48 to 72 inches (total for both doors), but custom options are available to fit unique needs. Careful measurement and planning—along with a focus on aesthetics, use, and cost—will ensure you wind up with a set of doors that look beautiful and work seamlessly in your home. Whether you’re replacing old doors or adding new elegance, the right width makes all the difference!

Standard heights are usually 80 inches (6 feet 8 inches), but 84 and 96-inch heights are also frequently available. Like width, custom heights can be made to order.

Do wider French doors cost more?
Generally, the wider the doors, the higher the price due to increased material and manufacturing costs. Installation and shipping fees may also be higher for large or heavy sets.

How do I ensure I’m ordering the correct width for my opening?
Measure the rough opening (the space between the framing studs, not just the old door), then check the manufacturer’s recommendations. Door units are usually slightly smaller than the opening to accommodate frames and adjustments.


French doors bring timeless beauty to any space. By understanding their standard widths, how to measure, and what to consider during selection and installation, you’ll be well on your way to enhancing your home with confidence.
