The most stunning curtains can fall flat if they are not hung correctly. Learning how to hang curtains is less about the fabric and more about how you frame the window: how high you mount the rod, how far you extend it, and how much fabric you use. And what works for a simple single window will not work for a grand two-story arch or a tricky corner.
"The details are not the details. They make the design." — Charles Eames
This guide covers both halves of the job: the core designer rules that apply to every window, and then the exact hanging technique for each window type in your home, from single windows to bays, arches, corners, and glass doors.
Quick answer: Mount the rod 4 to 6 inches above the frame (higher, near the ceiling, looks more high-end), extend it 6 to 12 inches past each side, and use enough fabric for 2 to 2.5 times the rod width so the panels look full. Hang curtains to the floor with a slight break. Then adjust the approach for your specific window type using the chart below.
The core rules for hanging curtains
Four numbers do most of the work. Get these right and almost any window looks intentional.
How high: Mount the rod at least 4 to 6 inches above the window frame. For a more dramatic, high-end look, go higher, up to a few inches below the ceiling. Hanging high draws the eye up and makes the window and the whole room feel taller. Our 4-step guide to measuring curtain rods walks through the exact numbers.
How wide: Extend the rod 6 to 12 inches past the frame on each side. This lets the open panels stack on the wall instead of the glass, so you get maximum light and the window looks larger.
How full: For panels that look rich rather than skimpy, aim for total fabric width of about 2 to 2.5 times the rod width. A quick formula: rod width times 2.5, divided by the number of panels, gives the width each panel should be. The right header or pleat style affects fullness too.
How long: Floor-length looks best in most rooms. A slight break, about half an inch of fabric resting on the floor, reads as tailored; a small float half an inch off the floor feels crisp and modern. For a full breakdown, see should curtains touch the floor.
Quick reference: where to place the rod by window type
| Window type | Rod placement | Panels |
|---|---|---|
| Single window | 4–6″ above frame (or near ceiling); extend 6–10″ each side | 2 panels |
| Multiple, small gaps | One long rod across all windows | Panels at the ends, or in each gap |
| Multiple, large gap | Separate rod on each window | A pair on each |
| Two-story / high ceiling | From above the top window to the floor, one continuous run | Extra-long panels |
| Arched | Straight rod 4–6″ above the arch's peak | Panels hang straight |
| Corner | Corner connector rod wrapping the corner | Continuous |
| Bay | Custom bay rod following the angles | 2–4 panels |
| Sliding glass door | Long rod, extend well past both sides | 2 panels (better stack-back) |
| French door | Rod above each door | 1 panel per door |
| Kitchen / bath | Café rod across the middle of the window | Café (tier) panels |
1. The classic single window
This is the foundation of all curtain hanging. For a single window in any room, the rules above are simple but transformative: hang the rod high, extend it wide, and frame the window with a panel on each side for a classic, balanced look.
2. Multiple windows on a single wall
When you have more than one window in a row, the key is to decide whether to treat them as a single unit or as individuals.
Scenario A: windows with small gaps between them
For two to four windows positioned closely together, you have two stylish options:
The unified look: Use one long curtain rod across the entire set of windows, with panels only on the far left and far right ends. This creates a clean, grand, cohesive statement.
The rhythmic look: Add single, evenly sized panels in the narrow gaps between each window for a custom-designed rhythm across the wall.
Scenario B: windows with a large gap (separated by a fireplace or art)
When a major architectural feature separates windows, treat them as individuals. Hang a separate pair of curtains on each window so they frame the central feature, be it a fireplace, a piece of art, or a console table, making it the undeniable focal point of the room.
3. Grand and architectural windows
These statement windows demand a dramatic approach.
Two-story and high-ceiling windows
Whether it is stacked windows or a large window over a sliding door, the rule is the same: do not break up the vertical line. Use one continuous set of extra-long ceiling-height curtains that hang from above the top window all the way to the floor. This creates a breathtaking sense of luxury and emphasizes the grand scale of your home.
Arched windows
The arch is a beautiful feature to be celebrated, not hidden. Mount a straight curtain rod 4 to 6 inches above the highest point of the arch and let the curtains hang straight down, framing the shape. This draws the eye upward and makes the ceiling feel even higher.
4. Tricky corners and angles
These unique spots can become the coziest corners in your home with the right treatment.
Corner windows
For two windows that meet in a corner, use a corner rod connector to create a single, continuous rod that wraps around the corner. This lets the curtains connect seamlessly, creating a cozy, enveloping feel perfect for a reading nook or bedroom corner.
Bay windows
A bay window is designed to be a room's feature. Use a custom bay window rod that follows the angles of the bay, then hang four panels for a floor-length bay (two for the center window and one for each side window) or two panels for a shorter bay. For a full walkthrough, see our bay window curtains guide.
5. Functional doors with glass
Glass doors need curtains that are both beautiful and practical.
Sliding glass doors: A common solution is a single, extra-wide panel on a long rod that you pull to one side. The problem is that one side then carries all the weight and needs a lot of stack-back space. The better functional solution is usually two panels, so both sides have room to stack back. See our complete guide to curtains for sliding glass doors.
French doors: Hang a curtain panel on the outside of each door. This frames the doors beautifully when closed and lets them swing open easily when the curtains are drawn back.
6. Specialty solutions for unique spaces
Finally, some rooms have unique needs that dictate the curtain style.
Kitchens and bathrooms: In spaces where privacy is needed but long drapes are not practical, café curtains are the perfect solution. These half-curtains cover the lower portion of the window, blocking the direct line of sight while letting light stream in from the top. Here is how to measure café curtains.
Outdoor spaces (pergolas and patios): Use durable, weather-resistant outdoor curtains to add shade, privacy, and a soft, resort-like feel. They look especially stunning paired with string lights.
Bedrooms (light control): For any window type in a bedroom, the priority is often light control. Layer any of the styles above with blackout blinds or shades for the ultimate flexibility.
Frequently asked questions
How high should you hang curtains?
Mount the rod at least 4 to 6 inches above the window frame. For a more dramatic, high-end look, hang it higher, up to a few inches below the ceiling. Hanging curtains high makes the window and the room feel taller.
How far should the curtain rod extend past the window?
Extend the rod 6 to 12 inches past the frame on each side. This lets the open panels rest on the wall instead of covering the glass, so you get more light and the window looks wider.
How wide should curtains be for a full look?
Aim for total fabric width of about 2 to 2.5 times the rod width. A quick formula: multiply the rod width by 2.5, then divide by the number of panels to get the width each panel should be.
Should curtains touch the floor?
In most rooms, yes. A slight break, about half an inch of fabric resting on the floor, looks tailored, while floating half an inch off the floor looks crisp and modern. Avoid short, above-sill curtains in living spaces.
How many curtain panels do I need?
A single window usually looks best with two panels. For very wide windows or doors, the number depends on the rod width and the fullness you want, using the 2 to 2.5 times rule above.
How do you hang curtains on an arched or bay window?
For an arch, mount a straight rod 4 to 6 inches above the highest point and let the panels hang straight down. For a bay, use a custom rod that follows the angles and hang two to four panels depending on the size and height of the bay.
