Okay, so curtain length is, like, my personal Everest. I’m sitting here in my cramped Ohio apartment, staring at my living room window where the curtains are—yep—about six inches too short. It’s giving “ankle socks in winter” vibes, and I’m low-key embarrassed every time someone comes over. Seriously, picking the right curtain length for your windows is such a game-changer, but it’s also a total minefield. I’ve screwed this up so many times, and I’m just gonna spill all my messy, real-life lessons here. Grab a coffee—mine’s already half-spilled on the table—and let’s dive into this.
Why Curtain Length Is My Nemesis
Curtain length isn’t just about aesthetics, though it’s huge for making a room feel polished. It’s about function too—keeping out drafts, hiding your nosy neighbor’s view, all that jazz. When I moved into this place last year, I thought, “Psh, curtains are easy.” Spoiler: I was wrong. My first attempt was these cheap, clearance-rack curtains for my bay window. They were so short, they looked like they were auditioning for a rom-com about bad interior design. I legit laughed, then cried a little, when I hung them up.

Here’s the deal: every window type—bay, casement, double-hung, you name it—has its own curtain length sweet spot. I learned this the hard way, and I’m still not over it. According to Better Homes & Gardens, the right drape length can make or break your room’s vibe. Let’s break it down, window by window, with all my fumbles included.
Curtain Length for Standard Double-Hung Windows
Double-hung windows are, like, the basic jeans of windows—everywhere, kinda boring, but super versatile. My living room has two of these, and I still got the curtain sizing wrong. The trick here is to aim for curtains that just kiss the floor or hover about half an inch above it. Anything shorter, and it’s like your windows are wearing capris. Anything too long, and you’re tripping over fabric like I did last week. True story: I stepped on my overlong curtains, yanked the rod down, and scared my dog. Not my finest hour.
- My Tip: Measure from the rod to the floor, then add an inch for the rod pocket. I forgot this once and ended up with curtains that barely reached the sill.
- Pro Move: If you’re lazy like me, get adjustable curtain rods from Target so you can tweak the height without drilling new holes.
Bay Windows and Curtain Length Drama
Bay windows are fancy, right? Like, they’re the architectural equivalent of a statement necklace. But they’re also a pain for window treatments. My dining nook has a bay window, and I thought I could just slap some standard curtains on it. Nope. The curtains were too short, and the whole setup looked like a kid wearing their dad’s suit.

For bay windows, you need longer curtains—think floor-length or even slightly puddling for drama. I read on HGTV that you should use multiple panels to follow the window’s curves. I tried this, but I cheaped out and got thin panels that looked like tissue paper. Big mistake. Go for thicker fabrics to balance the window’s grandeur. Also, measure each section separately—my bay window’s middle panel needed an extra six inches compared to the sides. Who knew?
Casement Windows: My Kitchen Curtain Fail
Casement windows, like the ones in my kitchen, are those crank-out ones that feel super old-school. I love them, but curtain length here is tricky. I hung these gorgeous linen drapes that were waaay too long, and they ended up pooling on the counter, knocking over my sad little basil plant.

For casement windows, go for sill-length or apron-length curtains (just below the sill). They’re practical, let you crank the window without fabric getting in the way, and still look cute. I switched to apron-length curtains from West Elm, and it’s been a game-changer. Just don’t do what I did and forget to hem them properly—I left pins in for a month, and my roommate still roasts me for it.
Sliding Glass Doors and Curtain Length Hacks
Sliding glass doors are their own beast. My apartment has one leading to a tiny balcony, and I wanted curtains to make it feel less like a fishbowl. I bought these floor-length drapes, thinking they’d be super chic. Wrong. They kept getting caught in the door track, and I ripped one trying to yank it free. Embarrassing? Yes. Did I learn? Kinda.
For sliding doors, floor-length curtains work best, but make sure they’re wide enough to cover the whole door when closed. I found a great tip on The Spruce: use a double rod so you can layer sheer and blackout curtains. I did this, and now I can sip my coffee on the balcony without the neighbors spying. Measure twice, cut once—or, like me, just buy pre-made panels and pray.
My Biggest Curtain Length Mistakes (So You Don’t Repeat Them)
I’ve made every curtain length mistake in the book, and I’m not too proud to admit it. Here’s my hall of shame:
- Buying Without Measuring: I thought all windows were “about the same size.” Nope. My bedroom curtains are still too short, and I’m too stubborn to replace them.
- Ignoring Fabric Weight: Thin curtains on big windows look sad. I learned this after my bay window disaster.
- Forgetting the Rod Height: Hanging the rod too low makes your windows look squat. Aim for a few inches above the frame—Architectural Digest has a great guide on this.
Wrapping Up This Curtain Length Rant
Look, figuring out the right curtain length for every window type is a journey, and I’m still stumbling through it. My apartment is a patchwork of curtain fails and small wins, but I’m learning. If I can save you from stepping on your own drapes or buying clearance-rack disasters, I’ll call that a win. Start with measuring—seriously, don’t skip it—and think about how you want the room to feel. Then, maybe don’t spill coffee on your windowsill like I did this morning.
