Your 2-Inch Slats Are Too Bulky (Try 1 1 2 Blinds Faux Wood Instead)

I remember standing in my first apartment—a 1940s walk-up with beautiful original trim—holding a set of standard two-inch blinds I’d bought on a whim. I snapped them into the brackets, and my heart sank. The headrail stuck out nearly an inch past the molding, looking like a cheap plastic hat on a tuxedo. It was my first lesson in window depth, and it’s why I now swear by 1 1 2 blinds faux wood for almost every renovation where space is at a premium.

• Slat Size: 1.5 inches (the Goldilocks zone for shallow frames).
• Ideal Depth: 2 to 2.25 inches for a perfectly flush inside mount.
• Material: Moisture-resistant composite that mimics real timber grain.
• Best For: Older homes with narrow casings and high-humidity rooms.

The Annoying Problem With the Default Slat Size

Most homeowners default to two-inch slats because they are the industry standard. They are everywhere. But standard does not mean universal. If you live in a home built before 1970, your window casings are likely shallower than modern builds. When you force a two-inch blind into a 1.75-inch deep frame, the headrail protrudes. This creates a gap that lets light leak in from the sides and, frankly, looks like a DIY project gone wrong. I’ve spent too many hours staring at headrails that look like they’re trying to escape the window to ever recommend forcing the fit.

I’ve seen designers overcorrect by dropping down to one-inch slats. While that solves the depth issue, it creates a new one: the pinstripe effect. Too many tiny slats can make a window look busy and cluttered, especially in a small bedroom. You can see why 1-inch faux wood window blinds fit better in very specific, narrow scenarios, but for a classic, high-end look, they often lack the heft of a larger slat. The 1.5-inch slat is the bridge between these two extremes, offering a substantial look without the bulk.

Enter the Goldilocks Solution: 1 1/2 Inch Window Blinds

The 1.5-inch slat is the interior stylist’s secret weapon. It has the visual weight of a plantation shutter but the versatility of a horizontal blind. When you install 1 1/2 inch window blinds, you are getting a cleaner, more tailored look. The proportions just feel right—they don't overwhelm a small window, yet they don't look spindly on a larger one. It’s a subtle shift that changes the entire geometry of the room, making the window feel wider and the ceiling feel more grounded.

I often explain to my clients why 1 1 2 blinds faux wood win every time when we are aiming for a balance between light control and a clean, flush profile. The 1.5-inch width allows for a shallower headrail, meaning you can achieve that elusive custom-built look even in windows that aren't perfectly square. It’s about creating a silhouette that feels integrated into the architecture rather than tacked on as an afterthought. On a warm October afternoon, seeing the sun bounce off these slats creates a soft, diffused glow that 2-inch slats just can't replicate in a shallow frame.

Why I Specify Faux Over Real Wood for This Exact Proportion

I’m a purist about a lot of things—linen, brass, wool—but when it comes to 1.5-inch slats, I’m team faux wood. Real 1 1 2 inch wood blinds are beautiful, but they are temperamental. Because the slats are thinner than the standard two-inch variety, they have less structural integrity. Over time, especially in a steamy bathroom or a kitchen where you're boiling pasta every night, real wood slats can start to 'smile' or twist under the weight of the ladder strings.

High-quality 1 1 2 inch faux wood blinds are made from a polymer or composite that is virtually indestructible. They won't yellow in the sun, and they won't warp. I once installed real wood blinds in a beach cottage only to have them look like wavy potato chips six months later. Since then, I’ve stuck to faux for the 1.5-inch profile. You get the grain texture and the matte finish without the maintenance nightmare. They are my go-to for kitchens because you can literally wipe off grease and pasta sauce with a damp cloth without worrying about the finish.

How to Style 1 1/2 Inch Wood Blinds Like a Pro

To keep your blinds from looking like they belong in a corporate office, you need to layer. I like to mount a matte black or aged brass rod about 4 to 6 inches above the window frame. Hang a pair of 200 gsm linen-blend drapes with a 2.5x fullness. This softens the hard edges of the slats. The 1.5-inch slat provides a crisp, horizontal backdrop that makes the vertical folds of the fabric pop. It's a classic pairing that works in everything from a farmhouse to a modern condo.

Don't forget the valance returns. If your blinds are slightly proud of the frame, the returns hide the hardware from the side view. If you’re looking for a more high-tech solution for light control, you might look into a 2 in 1 shade, but for a classic, layered aesthetic, the combo of 1.5-inch slats and linen panels is unbeatable. I recently did this in a guest room with 96-inch drop panels, and it made the 8-foot ceilings feel significantly taller because the eye wasn't stopped by a protruding 2-inch headrail.

The 'Flush Mount' Rule I Swear By for Older Homes

Before you order, grab a steel tape measure. Measure the depth of your window casing from the glass to the edge of the trim. For 1 1 2 blinds faux wood, you generally need 2 to 2.25 inches of clear space for a fully flush inside mount. If you only have 1.5 inches, the headrail will stick out slightly, but it will still look far more intentional than a larger blind. It’s that extra five minutes of measuring that separates a professional-looking install from a frustrating return process.

One mistake I see constantly: measuring only at the top. Older houses settle. Your window might be 34 inches wide at the top and 33.5 at the bottom. Always take three measurements—top, middle, and bottom—and use the smallest width. This ensures your 1.5-inch blinds won't scrape the sides of the casing every time you raise or lower them. When they fit perfectly, they look like custom millwork that was built into the house from day one.

Are 1.5-inch blinds harder to clean?

Slightly. Since there are more slats per window compared to 2-inch versions, there are more surfaces to dust. However, because the slats are narrower, they tend to collect less heavy dust buildup than wide shutter-style slats. A quick swipe with a microfiber cloth once a week keeps them looking brand new.

Can I install these on an outside mount?

You can, but I wouldn't recommend it. The beauty of the 1.5-inch slat is its low profile. Using them as an outside mount defeats the purpose of their slim design. If you must go outside mount, ensure you order a valance with custom returns to hide the brackets and the side of the headrail.

Do faux wood blinds look like plastic?

Not if you choose a matte or sandblasted finish. Avoid high-gloss options, which reflect light in a way that screams synthetic. A textured faux wood slat is almost indistinguishable from painted real wood once it is hung. I’ve had guests touch my blinds to check if they were real timber—the technology has come a long way.
