Stop Hanging Stubby Drapes on Short Wide Windows (Do This Instead)

I have spent more time than I care to admit staring at windows that look more like mail slots than architectural features. You know the ones—they sit high on the wall, wide and squat, making the whole room feel like it is crouching. When I first moved into my 1960s fixer-upper, the short wide windows in the bedrooms were dressed in these sad, polyester cafe curtains that ended right at the sill. It was the visual equivalent of wearing high-water pants to a black-tie gala. It did nothing but highlight the awkward proportions and make the eight-foot ceilings feel even lower.

• Mount your rods high and wide to trick the eye into seeing a larger window.
• Always opt for floor-length panels to create verticality, even if the glass ends mid-wall.
• Use a single, continuous headrail for hard treatments to avoid a cluttered, choppy look.
• Choose outside-mount Roman shades to hide the top of the frame and add perceived height.

The Mail Slot Dilemma: Why Squat Proportions Are So Hard to Dress

A wide narrow window is an architectural puzzle that most people solve incorrectly. Because the glass is stretched horizontally, our natural instinct is to follow that line with our window treatments. We buy short rods and short fabric, thinking we are being efficient. In reality, this just boxes in the window and draws a giant, heavy rectangle right in the middle of your wall. It breaks the vertical flow of the room and makes the ceiling feel like it is pressing down on you.

The challenge with short wide window treatments is balance. You have plenty of width, but zero height. If you dress only the glass, you are essentially highlighting a flaw. I’ve seen beautiful rooms ruined by a 'mail slot' window because the owner treated it like a tiny accent rather than a major design element. To make these windows work, you have to stop thinking about the glass and start thinking about the entire wall. You aren't just covering a window; you are creating a focal point that scales with the rest of the furniture.

Please Stop Hemming Your Curtains at the Sill

The most common mistake I see with window coverings for short wide windows is the 'apron' length drape. This is when the fabric ends exactly at the bottom of the window trim or, even worse, at the sill itself. Unless you are in a literal cottage or a kitchen with a sink in the way, this is a design crime. It creates a choppy, unfinished look that makes the wall feel segmented. It’s like stopping a coat at the waist when it really needs to be a trench.

When you cut your drapes short, you are telling everyone exactly where the window begins and ends. You lose the opportunity to use fabric as a tool for visual trickery. I once helped a friend who had installed custom 54-inch drop linen panels on her wide bedroom windows. The room felt stunted and cold, despite the high-quality 250 gsm fabric. We swapped them for 96-inch panels that hit the floor, and suddenly the room felt three feet taller. The lesson? Short windows do not require short curtains. In fact, they practically beg for the opposite.

The Counterintuitive Fix: Floor-to-Ceiling Drapery

The best way to handle window treatments for short wide windows is to lie. You want to pretend that your window is actually a massive, floor-to-ceiling architectural feature that just happens to be partially covered. To do this, mount your curtain rod about 4 to 6 inches below the ceiling line (or the crown molding) and extend the rod at least 10 to 12 inches past the window frame on each side. This is the 'high and wide' rule, and it is non-negotiable for squat windows.

By using 96-inch or 108-inch drapes, you create long, vertical lines that draw the eye from the floor all the way up. When the curtains are open, the fabric should mostly cover the wall, not the glass. This makes the window look twice as wide and three times as tall as it actually is. I prefer a heavy linen blend with a 2.5x fullness—meaning if your window is 70 inches wide, you want about 175 inches of fabric width. This ensures the drapes look lush and intentional, not like a thin sheet of paper stretched across the wall. Go for a French return rod so the fabric wraps all the way to the wall, blocking those annoying light leaks at 6 AM.

What to Do When Floor-Length Drapes Aren't an Option

Sometimes, the floor-length dream is dead. Maybe you have a radiator that would turn your drapes into a fire hazard, or a built-in desk that sits right under the frame. In these cases, you still need to fake the height. The answer is an outside-mount Roman shade. Instead of tucking the shade inside the window casing, mount it several inches above the frame—sometimes even halfway to the ceiling. When the shade is partially raised, the stack of fabric hides the top of the window, making it look like the glass continues much higher than it does.

I usually recommend a flat-fold Roman shade for a clean, modern look. Avoid the 'balloon' style shades that can look a bit dated and heavy on a wide narrow window. Choose a fabric with a subtle vertical stripe or a solid textured weave to keep the energy moving upward. If you’re worried about light, add a blackout liner. This also adds weight to the shade, helping it hang straight and crisp. It’s a tailored, functional solution that doesn't feel like a compromise.

Navigating Hard Treatments Without Looking Like a Cubicle

When you are looking for blinds for wide short windows, the biggest trap is the 'multi-blind' setup. People often see a wide window and think they need to buy three separate narrow blinds because a single wide one would be too heavy to lift. This is a mistake. It creates vertical breaks that make the window look cluttered and busy. Whatever you do, avoid splitting your wide window blinds into three clunky sections if you can help it.

Instead, look for a single headrail system. If weight is a concern, go for faux wood or high-quality composite materials which are often lighter than solid oak. I’m a fan of 2.5-inch slats for wide short window blinds. The larger slat size means fewer horizontal lines, which keeps the look cleaner and less like a corporate office. If you must have multiple blinds for functionality, try to hide them under a single decorative valance or a cornice box to maintain that unbroken horizontal line. It keeps the eye moving smoothly across the space rather than jumping over gaps.

When in Doubt, Go Minimalist with Rollers

If your style leans modern or industrial, sometimes the best wide short window blinds aren't slats at all, but a single, sleek roller shade. A continuous roll of fabric provides a clean, architectural finish that doesn't compete with the rest of your decor. Sometimes a modern home is begging for wide roller blinds because they disappear when they are up, allowing the window's shape to be what it is without the fuss.

I recently installed a 90-inch wide solar shade in a client's home office. The window was only 20 inches tall, sitting right at eye level when seated. We chose a 3% openness weave in a charcoal grey. It cut the glare on the monitor but kept the view of the garden. Because it was one single, unbroken piece of fabric, it looked like a deliberate design choice rather than a 'problem' window. It’s the ultimate minimalist fix for those awkward, high-set windows in basements or modern additions.

How do I measure for drapes on a wide window?

Measure the width of your window including the trim, then add 20-24 inches to that number for your rod length. For the fabric, multiply that total rod width by 2 or 2.5 to get the total width of the panels you need. For height, always measure from the floor up to where you want the rod to sit—usually 4-6 inches above the window.

Can I use vertical blinds on short wide windows?

Technically you can, but I wouldn't. Vertical blinds on a short window tend to look like a 1990s dentist's office. If you want the light control of blinds, stick to horizontal slats or a single roller shade. If you want the vertical lines, use floor-length drapery panels instead.

What fabric is best for wide windows?

Linen or linen blends are my go-to. They have enough weight to hang beautifully but aren't as stiff as velvet, which can look a bit 'theatrical' on a wide, squat window. A 300gsm linen provides great privacy and a soft, diffused light that makes any room feel more expensive.
