Standard Patio Door Size in Canada

Key Takeaways

• Standard sizes: Most Patio Doors in Canada are 60"–96" wide and 80" high, commonly in sliding or French styles.
• Custom solutions: Unique openings often require custom-built patio doors to ensure a perfect fit and design match.
• Climate-conscious design: Use double/triple glazing and vinyl or fibreglass frames for energy efficiency in Canadian winters.
• Space and style: Choose sliding for space-saving functionality or French for a wide, elegant entry.
• Professional installation is crucial, as it guarantees weather sealing, energy efficiency, and long-term performance.

Understanding Standard Patio Door Sizes

Choosing the right patio door size has a significant impact on your home's functionality, comfort, and overall curb appeal. While many homes adhere to standard measurements, understanding the various options — and knowing when to opt for custom — is crucial to a successful project.

Standard Sliding Patio Door Sizes

Sliding doors are the most common patio door style in Canada. They save space because they slide along a track rather than swinging open.

Benefits of sliding patio doors

• Ideal for compact spaces or balconies
• Large glass panels maximize natural light.
• Smooth operation and minimal clearance needed

Tony Wong adds:
“Sliding doors are perfect where floor space is tight. They allow full-height glass without needing swing clearance.”

Standard French Patio Door Sizes

French doors offer a more traditional and elegant entryway, and are popular in larger homes or those with ground-level walkouts.

Benefits of French patio doors:

• Create a grand, symmetrical opening
• Bring in abundant natural light.
• Swing open fully for ventilation and moving large furniture.

Helen Sin, Consumer Success Manager at Canadian Choice Windows & Doors :
“French doors frame your backyard like a painting. They add character while connecting your indoor and outdoor spaces beautifully.”

Oversized and Multi-Panel Patio Doors

Contemporary homes often utilize oversized or multi-panel systems to achieve panoramic views and seamless indoor-outdoor flow.

Key points

• Require reinforced framing and structural support
• Deliver dramatic views and daylight.
• Greater upfront investment and more detailed installation requirements

Sliding vs French Patio Doors: Pros and Cons

Factors Influencing Patio Door Size

Selecting the right size is about more than filling an opening — it’s about creating the right flow, comfort, and performance.

Space and Layout

• Large decks/backyards suit wide French or multi-panel sliding doors.
• Smaller patios or apartments benefit from standard sliding doors.
• Consider furniture placement and traffic patterns when choosing width.

Climate and Energy Efficiency

• Canadian winters require energy-efficient doors with:
  • Double or triple glazing
  • Low-E coated glass
  • Vinyl or fibreglass frames
• Proper weatherstripping prevents drafts and condensation.

Architectural Style

• Modern homes often feature wide sliding or lift-and-slide systems.
• Traditional homes often feature classic French doors with wood grain finishes.
• Your patio door should complement — not compete with — your home’s design.

Building Code & Permit Considerations

While no single “patio door code” exists, installations must meet the National Building Code of Canada (NBCC) and municipal bylaws:

Tip: Always confirm local permitting requirements before starting a renovation involving structural changes.

Custom Patio Door Solutions

Standard sizes work for most homes, but unique spaces often need custom patio doors.

Benefits of Custom Doors

• Tailored to non-standard openings
• Allows creative combinations of materials and glazing
• Integrate advanced features (built-in blinds, smart locks, decorative glass)

Standard vs Custom Patio Doors

How to Measure for Patio Doors (Step-by-Step)

Accurate measurements are vital, especially for custom orders.

Step 1 — Measure Width

• Measure at the top, middle, and bottom of the opening.
• Use the largest measurement and round down to the nearest 1/8".

Step 2 — Measure Height

• Measure from the finished floor to the top of the frame.
• Consider the flooring thickness when planning renovations.

Step 3 — Check for Obstructions

• Confirm there are no light fixtures, walls, or cabinets blocking swing or slide paths.
• Allow at least 1–2 inches of clearance around the frame for installation.

Patio Door Material Options

Energy tip: In cold regions, pair vinyl or fibreglass frames with triple-pane low-E glass for best performance.

Professional Installation and Why It Matters

Even the best patio door won’t perform well if installed incorrectly.

Benefits of professional installation

• Professional installation ensures a precise fit that prevents gaps and drafts
• Correct flashing and sealing prevent water intrusion.
• Ensures long-term structural stability
• Protects warranty and code compliance
