Sliding patio doors glide sideways on a track and need no swing space, which suits tight patios and furniture near the door. French doors swing open like regular doors and give a wide, fully open passage, which suits larger spaces and a classic look. The right choice depends on your space, view, ventilation, and style.

When Do Sliding Doors Make Sense?
Sliding doors fit when space is limited, when you want a large glass view, or when you want a clean modern look. Because the panels glide, nothing swings into the room or onto the patio. They come in a wide range of widths, from smaller openings to very large ones.
When Do French Doors Make Sense?
French doors fit when you want a classic look, a wide opening for moving furniture, or a doorway that feels more like an entry. They need clear space to swing, so check the room and the patio layout.
What Does Left or Right Venting Mean?
On a sliding door, the venting side is the panel that opens. Left-venting and right-venting describe which side slides. Decide this by standing outside and looking at the door, and confirm the configuration before you order, since it affects how the door fits your space. See the related FAQ on our Windows and Doors pages.
What About Screens, Security, and Upkeep?
Ask about screen options, locks, and the frame material and finish for the exact door. Both styles need clean tracks or hinges and good weatherstripping. Match the details to the product, not the style.
