Comparing sliding and French (hinged) patio doors on cost, airflow, space requirements, and energy efficiency.
Patio doors are one of the few replacement projects where the choice isn't really about material — it's about how the door operates. Sliding and French (hinged) patio doors solve the same problem — a wide glass opening to your backyard or deck — in very different ways, and the right one depends on your available space and how you actually use the opening.
Sliding patio doors run on a track and require zero swing clearance, making them the default choice for tight patios or furniture layouts close to the opening. They typically cost $1,200–$4,500 installed and open only half the doorway width at a time, since one panel stays fixed. A clean, well-maintained track seals very tightly against drafts.
French patio doors are a pair of hinged panels that swing fully open, giving you the entire doorway width for airflow and furniture moves. They cost more — typically $1,800–$6,500 installed — due to the additional hardware and framing, and they require clear swing space on whichever side they open. Their classic look is a common match for traditional architecture.
Sliding doors are the better fit for tight spaces, modern aesthetics, and a lower upfront cost. French doors cost more and need swing clearance, but they open the full doorway width and suit traditional architecture. If floor space next to the door is limited, sliding wins by default; if you have the clearance and want a classic look, French doors are worth the premium.
