Why Automating a Narrow 23 Inch Roman Shade Is Harder Than It Looks

I have a love-hate relationship with the narrow window next to my front door. It lets in great morning light, but it also lets delivery drivers see me in my pajamas at noon. Finding a 23 inch roman shade to fit that specific sliver of glass felt like a custom engineering project rather than a simple home upgrade.

Quick Takeaways

• Standard 24-inch retail shades will not fit a true 23-inch frame without jamming.
• Internal battery motors often require more width than a 23 in roman shade provides.
• Fabric weight is the silent killer of narrow shade automation.
• Zigbee or Thread protocols are more reliable than Bluetooth for entryway setups.

The Skinny Window Problem (And Why Off-the-Shelf Fails)

Most big-box retailers treat window sizes like t-shirt sizes: Small, Medium, and Large. If your window is exactly 23 inches wide, a 24-inch off-the-shelf shade is a non-starter, and a 22-inch shade leaves a massive, ugly light gap on both sides. This is where the frustration peaks for renters and homeowners alike.

To get that high-end, tailored look, you almost always have to step up to custom roman shades. When you are dealing with a narrow 23" roman shade, a quarter-inch of clearance is the difference between a smooth lift and a fabric tear. I learned the hard way that 'close enough' isn't a strategy when motors are involved.

Squeezing a Smart Motor Into a 23" Roman Shade

Here is the technical hurdle: most decent tubular motors are about 14 to 18 inches long. When you add the drive gears, the end caps, and the battery wand, you quickly run out of real estate. Many DIY kits for a roman shade 23 inches wide fail because the battery tube literally won't fit inside the headrail alongside the motor.

I found that if you are tight on space, switching to hardwired motors can be a lifesaver. By removing the need for an internal battery pack, you reclaim about 6 inches of internal rail space. It means running a thin wire, but it beats having a bulky battery pack Velcroed to your wall like an eyesore.

Fabric Choice Makes or Breaks Narrow Blinds

A narrow shade has less weight to help it drop naturally. If you pick a heavy, thick velvet for a shade that is only 23 inches wide, the fabric will bunch up and resist the motor. It ends up looking like a lumpy burrito at the top of your window instead of a crisp stack of folds.

I always suggest ordering fabric samples before you commit to the full build. Hold the fabric in your hand and fold it. If it feels stiff or overly bulky, it will likely cause the motor to strain and trigger an 'obstruction' error. Light linens or thin polyesters are your best bet for a 23 in roman shade.

Automating the Taller Narrow Windows

The challenge doubles when you have an extreme aspect ratio, like roman shades 23 x 72. These long, skinny shades are notorious for 'telescoping'—that annoying thing where the fabric starts to veer to the left or right as it rolls up. Because the shade is so narrow, there is very little margin for error in the lift cord alignment.

For these taller narrow window setups, precision is everything. I spent two hours leveling my headrail with a laser level because even a 1-degree tilt meant the fabric would rub against the window frame by the time it reached the bottom. If your shade isn't perfectly level, the motor will burn out trying to fight the friction.

The Final Polish: Blackout Without the Bulk

If this shade is for a bedroom or a front door where privacy is non-negotiable, you want blackout capability. But adding a thick blackout liner to a narrow shade can make the 'stack' (the height of the shade when fully raised) way too deep. I prefer using a single-layer blackout fabric rather than a face fabric plus a liner.

For those who don't want to play 'engineer' with motor torque and cord tension, buying pre-assembled motorized blackout roman shades is a legitimate shortcut. It saves you the headache of trying to find a motor short enough to fit the 23-inch constraint while still having enough power to lift a 72-inch drop.

Personal Experience: My 'Dumb' Mistake

I once tried to save $50 by using a generic Bluetooth motor on a narrow entryway shade. Every time I walked through the door and wanted to close it, the app would take 10 seconds to 'discover' the device. It was infuriating. I eventually swapped it for a Zigbee motor that connects to my hub instantly. Lesson learned: don't skimp on the protocol for high-traffic areas.

FAQ

Can I trim a 24-inch motorized shade down to 23 inches?

Almost never. Trimming the headrail usually involves cutting into the motor housing or the drive shaft. If you need a 23-inch fit, buy it custom-sized from the start.

How long does the battery last on a narrow shade?

Since the fabric is light, you'll usually get 6 to 8 months on a single charge. If you use a solar charging strip, you might never have to plug it in at all.

Does a 23-inch shade work with Alexa?

Yes, as long as the motor uses a compatible bridge or protocol like Zigbee or Matter. You can set a routine so the shade closes automatically at sunset for instant privacy.
