You've probably spent hours staring at that chaotic pile of shoes and tangled hangers. It’s frustrating. You want that Pinterest-perfect look, but your budget says "Swedish meatballs" while your dreams say "custom boutique." Honestly, IKEA shelves for closet setups are the unofficial gold standard for a reason. They work. But if you just walk into the blue warehouse and grab the first white box you see, you're gonna have a bad time.
I've seen so many people try to force a square peg into a round hole—or in this case, a 15-inch deep Billy bookcase into a 12-inch reach-in closet. It’s a mess. People assume "closet" means you have to buy the stuff labeled "closet," but that's a rookie mistake.
The PAX Problem and Why It’s Still the King
PAX is the big one. If you search for IKEA shelves for closet ideas, PAX will dominate 90% of your feed. It’s deep. It’s sturdy. It feels like a real built-in. But here is the thing: PAX is massive. If you have a standard reach-in closet with sliding doors, PAX might actually be too deep. Most PAX frames come in two depths: roughly 13 inches and 22 inches. If you go for the 22-inch version in a small closet, you’ll lose all your floor space and probably won't be able to close the door.
I remember helping a friend install these in a 1950s ranch home. We didn't measure the trim. We spent four hours building the frames only to realize the door casing prevented the drawers from sliding out. That’s the stuff the influencers don't tell you. You need clearance. Not just for the frame, but for the Komplement drawers to actually function.
Why Komplement is the Secret Sauce
The shelves themselves are just particle board and melamine. They’re fine. But the Komplement system—the drawers, the pull-out jewelry trays, the pants hangers—is where the magic happens.
- Pull-out trays with felt inserts: Great for watches or sunglasses.
- Glass-front drawers: These make it easy to see your sweaters without digging.
- The mesh baskets: Use these for gym clothes because they actually let the fabric breathe.
One thing people overlook is the lighting. IKEA sells the OVERSIDAN LED light bar specifically for PAX. It has a sensor. You open the door, the light kicks on, and suddenly your closet doesn't feel like a dark cave. It’s a game changer for about $30.
Boaxel is the Underdog for Tight Spaces
If PAX is the heavy-duty SUV of closets, Boaxel is the nimble mountain bike. It’s a wall-mounted system. It’s way cheaper. It’s also much more forgiving if your floors are uneven—which, let’s be real, most floors are.
Because it hangs on a top rail, you aren't fighting with shims to get the thing level. You just level the top rail, screw it into the studs (please, for the love of everything, find the studs), and hang the uprights.

Honestly, Boaxel is better for kids' rooms. Kids grow. Their clothes change sizes. With Boaxel, you can pop a shelf out and move it up six inches in thirty seconds. You can’t do that easily with the screwed-in supports of a PAX. The downside? It looks a bit more "utility." It’s metal. It’s wire. It’s not that high-end wood look. But if you're doing a laundry room or a small reach-in, Boaxel is probably the smarter play.
The Billy Bookcase Hack
Wait, a bookcase? In a closet?
Yes.
If you have a very narrow closet, the Billy bookcase is often the only thing that fits. It’s only 11 inches deep. This is the "pro move" for shoe storage. Standard IKEA shelves for closet systems are often too deep for shoes, wasting space. A Billy fits a pair of sneakers perfectly without an inch of wasted air.
Materials Matter: The Truth About Particle Board
Let's talk about the elephant in the room. IKEA isn't solid oak. It’s particle board wrapped in a foil or melamine finish. It’s susceptible to moisture. If you live in a very humid climate or you're putting these shelves in a damp basement closet, you need to be careful.
Overloading is the other killer. I've seen Billy shelves sag like a wet noodle because someone stacked 40 pairs of heavy leather boots on a single span. If you're using wide shelves, you have to support the middle.
Stability and Safety
You have to anchor these to the wall. No exceptions. IKEA has had massive recalls in the past (mostly regarding the Malm dressers) because of tip-over risks. Closets are high-traffic areas. You’re pulling on drawers, you’re reaching for high shelves. If that PAX frame isn't bolted into a stud, it’s a giant wooden trap.

- Use a stud finder.
- Don't rely on the tiny plastic anchors that come in the box if you're hitting drywall.
- Buy some heavy-duty toggle bolts or "Zip-Its" if you can't find a stud where you need one.
The Cost Reality of "Budget" Shelving
People think they’re going to get a whole walk-in done for $200. You aren't.
The frames are cheap. The shelves are cheap. But the drawers? The drawers are where they get you. A single PAX drawer can run you $40 to $60 depending on the size and material. By the time you add five drawers, a glass shelf, and some pull-out racks, you’re looking at $600 to $800 for one section.
It’s still significantly cheaper than a custom California Closets install, which could easily run you $5,000 for the same space. But don't walk in thinking it's pocket change.
Customizing the Look
The "IKEA look" is very recognizable. If you want to avoid that "I just moved into my first apartment" vibe, you have to customize.
Paint the Backing: The flimsy cardboard back of a Billy or PAX is ugly. Before you nail it on, wallpaper it or paint it a bold color. It adds depth.
Swap the Hardware: IKEA handles are fine, but they’re basic. Go to Etsy or even Amazon and find some heavy brass or matte black pulls. It’s a ten-minute swap that makes the whole closet look like it cost three times as much.
Trim it Out: This is the most advanced move. If you use baseboards and crown molding around your PAX frames, you can make them look truly built-in. It fills those weird gaps between the top of the shelf and the ceiling.

Common Mistakes to Avoid
Measurements. I can't say it enough. Measure the height, the width, and the depth—and then do it again. But also measure your door swing.
Nothing is worse than realizing your closet door hits your new shelves. Or that you can't open the left-hand drawer because the closet door frame is in the way.
Also, consider the baseboards. Most IKEA units have a small cutout at the back to clear a standard baseboard, but if you have thick, modern baseboards, the unit won't sit flush against the wall. You’ll either have to cut your baseboard or notch the IKEA frame.
Actionable Steps for Your Closet Project
First, clear everything out. You can't visualize a new system while staring at your old piles of clothes.
Second, use the IKEA Home Planner tool on their website. It’s clunky and sometimes feels like it was designed in 2005, but it’s essential for PAX. It will tell you exactly which hinges you need and if your drawers will collide.
Third, check the "As-Is" section. Seriously. People return PAX frames all the time because they didn't fit. You can often find a $200 frame for $60 just because the box was opened.
Finally, gather your tools. You need more than the little Allen wrench they give you.
- A power drill with a clutch (so you don't strip the soft wood).
- A rubber mallet for tapping pieces together without denting the finish.
- A long level.
- A friend. Building a PAX frame alone is a recipe for a broken frame and a bruised ego.
Start with one section. Don't try to do a whole 10-foot walk-in in one Saturday. Get one frame level, anchored, and finished. You'll learn the quirks of the hardware and the second one will go twice as fast. Once the frames are in, you can take your time adding the "fun" stuff like jewelry trays and lights.
