How Many Curtain Panels for a French Door?
Quick answer: one pair (2 panels) for a standard 36-inch French door. Two 42–50-inch panels on a 44-inch rod give about 2× fullness while leaving the door free to swing.

The panel rule
One pair of panels handles a standard French door. A 36-inch door gets two 42–50-inch panels — wider than the door so they stack with fullness, and when drawn they cover the glass completely for privacy.
Rod width and fullness
Mount the rod 4–8 inches wider than the door — about 44 inches for a 36-inch door — and keep fabric at 1.5–2× the rod width, or 66–88 inches across two panels. The extra rod width is what lets the door open without catching the fabric.
| Door width | Rod width | Fabric total (1.7×) | Panels |
|---|---|---|---|
| 30 in | 38 in | ~65 in | 2 × 34–50 in |
| 36 in | 44 in | ~75 in | 2 × 42–50 in |
| 48 in (double) | 56 in | ~95 in | 2 × 50–60 in |
Length: floor vs sill
Floor length is standard — hang the rod 4–6 inches above the frame and let panels just kiss the floor, about 80–84 inches for a standard door. Sill length works for a door with a bench seat, but floor length looks cleaner on tall doors.
One panel or two
A single wide panel (70–80 inches) covering the whole opening is a clean modern look — simpler and often cheaper. The trade-off: you can't open one half independently, so match the choice to how you actually use the door.
Doors that swing in
If the French door swings inward, the rod must sit far enough from the frame that the open door doesn't hit the panels — mount it 8–12 inches out or use a hold-back. Inward-swinging doors are the number one reason panels get torn off.
Worked example: a 36-inch French door
- Rod = 36 + 8 = 44 in
- Fabric = 44 × 1.7 ≈ 75 in
- Two panels ≈ 38 in each → buy 42–50-in panels
- Length = rod height to floor ≈ 84 in
FAQ
One pair (2 panels) is enough for a standard 36-inch French door. Two 42–50-inch panels on a 44-inch rod give roughly 2× fullness.
The rod should be about 4–8 inches wider than the door — 44 inches for a 36-inch door — and fabric total 1.5–2× that, about 66–88 inches.
No — for daily use, stack panels at the sides so the door opens freely. Full coverage is for privacy at night.
Floor length is standard — rod 4–6 inches above the frame, panels just kissing the floor (80–84 inches for a standard door).
Yes — a single wide panel (70–80 inches) is a clean modern look, simpler and often cheaper.
