Summary: A standard patio door size is typically 60 or 72 inches wide and 80 inches tall for a two-panel sliding door. Larger sliding doors and French patio doors come in different dimensions, with some models reaching 96 inches tall. Available sizes vary by manufacturer, door style, and configuration.
A new patio door can make a big difference in how your home looks and feels, but finding the right fit starts with knowing your measurements. Standard patio door sizes are a helpful start, especially if you’re replacing an existing door and want to avoid changing the opening.
At NEXT Door & Window, we help homeowners throughout the Chicago suburbs, Madison, WI, and St. Louis find patio doors that fit their home’s design and budget. We’ll put that experience to work in this guide, walking through standard patio door dimensions for sliding and French doors, how to read measurements, and when a custom fit makes sense.
Standard Patio Door Sizes at a Glance
The table below features general size references, not exact frame dimensions. Patio door sizes vary by manufacturer, product line, and panel configuration.
| Door Configuration | Common or Available Widths | Available Heights |
| Two-Panel Sliding | 60, 72, or 96 inches (5, 6, or 8 feet) | 80 inches; 96 inches on select models |
| Three-Panel Sliding | 108–144 inches (9–12 feet) on select models | 80 inches; taller options vary |
| Four-Panel Sliding | Approximately 120, 144, or 192 inches (10, 12, or 16 feet) | 80 or 96 inches on select models |
| Two-Panel Hinged French | Commonly 48–72 inches (4–6 feet) | 80 inches; taller options available |
| Three-Panel French-Style | Varies by manufacturer and fixed-panel configuration | 80 inches; taller options vary |
For taller openings, some patio doors are available in 8-foot (96-inch) heights. Patio doors come in different panel configurations, so their dimensions vary more widely than standard front door sizes.
Standard Sliding Patio Door Sizes
A standard size sliding patio door typically measures 60 or 72 inches wide by 80 inches tall, though we also offer larger configurations. One panel slides while the other stays fixed, leaving a walk-through opening narrower than half the door’s total width, depending on the frame and panel design.
How to Read Patio Door Dimensions
Patio door dimensions are usually listed as width × height. For example, if you see 6/0 × 6/8, that means 72 inches wide by 80 inches tall. Remember these are nominal measurements, so you’ll still need to check the manufacturer’s exact dimensions before ordering.
Rough Opening vs. Door Unit Size — What Homeowners Get Wrong
The rough opening is the framed space in your wall where your patio door will go. A door labeled 72 inches wide won’t necessarily have a frame that’s exactly 72 inches wide, so we always check the manufacturer’s measurements before installation.
During patio door replacement, we measure your existing opening, especially in older homes where previous renovations or non-standard framing can affect the fit. If needed, we’ll help you determine whether a different door size or framing adjustments are the better option.
French Patio Door Sizes vs. Sliding Door Sizes
Traditional French patio doors swing open on hinges and commonly measure 48–72 inches wide by 80 inches tall. If you’re considering a 72-inch double French door, each panel is roughly 36 inches wide, so make sure you have room for the doors to swing open.
Love the look of French doors but don’t have much room for them to swing? Our sliding French patio doors give you that same classic style while moving along a track instead.
When to Go Custom — Non-Standard Patio Door Sizes
- Your Opening Isn’t a Standard Size: Older homes sometimes have door openings that don’t match today’s common sizes.
- You’re Planning a Remodel: If you’re widening an opening or following specific plans for your renovation, a custom-sized door may be the better fit.
- You Want a Wider Entryway: If accessibility is a priority, consider the clear opening width rather than the overall door size. The 2010 ADA Standards for Accessible Design specify a 32-inch minimum clear width for applicable accessible doorways. This is a useful reference for homeowners, although these standards generally don’t apply to private residences.
Custom patio doors typically cost more and take longer to manufacture. We can help you explore options for larger openings, including sliding French doors up to 16 feet wide and bi-fold doors up to 22 feet wide.
We’ll also help you compare vinyl vs. fiberglass patio doors and understand what ENERGY STAR ratings mean for your home.

FAQ — Standard Patio Door Sizes
What Is the Rough Opening for a 72-Inch Patio Door?

How Wide Is a 6-Foot Patio Door?
