Most people who hang curtains over french doors make the same mistake: they mount the rod too low and too narrow, so the panels crowd the glass and snag every time the doors swing. French doors move, and your window treatment has to respect that motion. Do it correctly and you get privacy, light control, and a soft frame around the doors; do it wrong and you fight jammed panels and gaps that let the neighbors see in. This guide covers rod placement, curtain length, hardware choices, and the exact measurements that keep everything working smoothly.

Understand the Clearance Problem First
Unlike a fixed window, French doors open into or out of the room. If the doors swing inward, panels hung across the top will drag against the door as it opens unless you give them somewhere to go. The whole strategy of dressing French doors is about pushing the fabric out of the swing path. That means mounting the rod higher and wider than you would for a normal window, so the open curtains stack completely off the glass and clear of the door leaf.
Measure the door swing before you buy anything. Open both doors fully and note how far into the room the leading edge travels. Your curtain stack-back needs to sit beyond that arc, or you will be tucking fabric behind the door every time you walk through.
Where to Mount the Rod
Height and width are the two numbers that make or break the look. For height, mount the rod 4 to 6 inches above the door trim, or higher if you want to draw the eye up and make the wall feel taller. In rooms with 9-foot ceilings, hanging closer to the ceiling and letting panels fall floor-length is a designer trick that adds instant height.
For width, extend the rod 8 to 12 inches past each side of the door casing. That extra reach, called stack-back, gives the panels a place to bunch when open so they clear the glass entirely. On a standard 60-inch-wide double French door, plan for a rod at least 76 to 84 inches long.
- Rod height: 4 to 6 inches above trim, or near the ceiling for drama.
- Rod width: door width plus 16 to 24 inches total.
- Bracket anchoring: hit studs or use toggle bolts; loaded panels are heavy.
Choosing the Right Curtain Length
Length depends on the effect you want and how the doors are used. Three lengths work here:
- Floor-length (most popular): panels that just kiss the floor or break slightly. Best for a formal, finished look on interior French doors.
- Puddle length: 2 to 4 inches of fabric pooling on the floor for a soft, luxurious feel, though it collects dust and is not ideal for high-traffic doors.
- Sill or apron length: shorter panels that stop above the floor, useful for doors leading to a busy patio where long fabric would drag.
Pro tip: always buy panels an inch or two longer than your measured drop and hem them, rather than hoping a stock length lands perfectly. Ready-made panels come in standard 84, 96, and 108-inch lengths, so measure from the rod to the floor and round up.
Hardware and Mounting Options
You have three main routes, each with trade-offs:
Wall-Mounted Rod (Recommended)
A single rod mounted on the wall above and beyond the doors is the most versatile and best-looking option. It lets panels stack fully off the glass and handles floor-length drops. Choose a rod diameter of 1 inch or more for wide spans so it does not sag under the weight of two long panels.
Door-Mounted Rods
Sash rods or tension rods installed directly on each door hold the fabric flat against the glass and travel with the door. This is the go-to for glass door panels where you want privacy without blocking the doorway. Use a rod at the top and bottom of each panel so the fabric stays taut and does not billow when the door moves.
Ceiling-Mounted Track
For a clean, modern look with maximum height, a ceiling track lets panels slide completely clear of the doors. It costs more but is ideal for tall walls and heavy drapery.
Step-by-Step Installation
- Measure door width, then add 16 to 24 inches for total rod length.
- Mark bracket height 4 to 6 inches above the trim, using a level to keep both sides even.
- Locate studs; where none exist, install heavy-duty wall anchors or toggle bolts rated for at least 20 pounds each.
- Mount the end brackets, then a center support bracket if the span exceeds about 48 inches to prevent sag.
- Hang the panels, open the doors fully, and confirm the fabric clears the swing. Adjust bracket width if it does not.
- Hem or adjust length so panels break cleanly at the floor.
Fabric and Light Control
French doors are mostly glass, so fabric choice controls both privacy and glare. Blackout-lined panels block light for bedrooms and media rooms. Light-filtering linen or cotton softens harsh sun while keeping the room bright. For a layered look, pair sheer panels underneath with heavier drapes on top, letting you dial privacy up or down through the day. If the doors face south or west, a thermal or blackout lining also cuts summer heat gain noticeably.
What It Costs
Dressing a set of French doors runs a wide range depending on quality:
- Budget: ready-made panels and a basic rod, $40 to $120 total.
- Mid-range: lined panels and a solid 1-inch rod with center support, $150 to $350.
- Custom: made-to-measure drapery, motorized track, or designer fabric, $500 to $1,500-plus.
Common Mistakes to Avoid
A handful of errors show up again and again on French doors. Mounting the rod at the exact width of the casing is the biggest one; the panels have nowhere to stack and permanently cover part of the glass. Skipping a center support bracket on a wide span is another, since two floor-length panels are heavy enough to bow a thin rod over time. People also forget to account for the door handle: a lever or knob that sits proud of the surface can catch fabric, so on door-mounted rods keep the panel taut with both a top and bottom rod. Finally, resist the urge to use flimsy tension rods for heavy drapery on a wall mount, because they slip and drop under load. Match the hardware weight rating to the fabric, and test the full door swing with the panels installed before you call the job finished.
Coordinating With Sidelights and Transoms
Many French door units include narrow sidelight windows or a transom above. You do not have to dress every piece of glass. A common approach is to run one wide rod above the entire assembly, letting the panels frame the whole unit while the sidelights and transom stay bare for light. If privacy at the sidelights matters, thin sash rods with gathered sheers on each narrow window keep the look tidy without competing with the main drapery. Keeping the same fabric family across all the treatments ties the wall together.
Frequently Asked Questions
Should curtains for French doors be floor length?
Floor-length panels look the most polished and are the standard choice for interior French doors. If the doors get heavy foot traffic to a patio, a sill or apron length avoids fabric dragging underfoot.
How wide should the curtain rod be for French doors?
Extend the rod 8 to 12 inches beyond each side of the door casing so the open panels stack completely off the glass. For a 60-inch double door, that means a rod of about 76 to 84 inches.
Can I hang curtains directly on French doors?
Yes. Sash or tension rods mounted at the top and bottom of each glass panel hold fabric flat and move with the door, which is ideal when you want privacy without blocking the doorway.
How high above French doors should the rod go?
Mount it 4 to 6 inches above the door trim for a balanced look, or closer to the ceiling if you want the room to feel taller and use floor-length panels.
The Bottom Line
The secret to hanging curtains over french doors is simple: go high, go wide, and respect the door swing. Mount the rod above the trim and well past the casing so panels clear the glass, pick a length that suits the traffic, and anchor the hardware into studs or heavy toggles. With the right measurements the doors open freely, the light is yours to control, and the whole entry looks intentional rather than improvised.
