Cutting An IKEA LACK Shelf To Size

Ever wonder what’s inside an Ikea LACK shelf? If it can be cut down to size? It can be, but they are flimsy and you’ll only want to do it if you’re putting the cut end up against a wall. I’ve now cut 3 of these so I thought I’d share.
The first time I used LACK shelves was in the sitting room at our last house. They happened to fit between two walls with around 1/2″ to 3/4″ to spare which you really need because walls are never perfectly straight, you need to allow for texture, and that 1/4″ gap on each side really goes unnoticed. These are the large size in the dark finish.
The next time I used LACK shelving was in my new study where I put 6 of them together to create two long shelves. I was inspired by this much more expensive home my family built for a custom home client. If I had done staggered shelves like this, it would have been much easier so this is a look you can consider instead of cutting them to size.
Back in my study, I used 6 of the medium sized LACK shelves. When I measured, lining 3 of them up side-by-side was the perfect width for the space with 1/4″ to spare. When I actually went to hang the final shelves on the right side, they wouldn’t fit because of the subtle saves in the wall. The side wall was tighter farther away from the back wall where I had measured. Since these are installed by sliding them back onto their hardware, that didn’t work out. So I trimmed them.
I ran into this problem again installing a long LACK shelf in the laundry room. When I measured, I knew it would be tight, but thought I could scoot the washer and dryer over a bit (but actually could not). After stepping back and looking at the space, I decided that the perfect length would be 2 inches shorter.
First, unwrap the end of the shelf that you want to cut. Pay attention to where the final screws go. I wanted them on the bottom, so I made sure that I was cutting from the correct side. Only the left side would be up against a wall, so I made sure that I cut on the left side, looking from the front with the screws on the bottom. I didn’t unwrap the entire shelf so it would be protected while being moved around.
Wrap the shelf in blue tape – all the way around.
Mark your measurements. I wanted the shelf 2″ shorter and measured to 2-1/4″ to allow for variations in the wall.
Draw a line all the way around the shelf (unless you have a saw that can cut all the way through it, most of us don’t).
No action shots here, but here’s the inside of a LACK shelf. Now you can see why they are so cheap! I used a circular saw to keep the cut as straight as possible. Cut one way all the way across, then turn the shelf over and cut again. I started at the front of the shelf so it would have a great line. As you can see, on the back of the shelf (on the left) my lines didn’t line up perfectly.
So that’s how you can cut a LACK shelf should it not fit perfectly in the space you want.
Update: If you need a pretty edge on the cut-side, consider peeling the end off of the trimmed-off piece and gluing it back onto the shelf. I haven’t tried this, but it looks possible.

Another note: The next problem with hanging LACK shelves in very specific spots is that the holes almost never line up with a stud. I don’t hang shelves on drywall anchors alone since I use them for books & other heavy objects. I put a screw in each side to hang the hardware where I want it to go and then find studs. I double check by drilling a tiny hole and making sure that it hits the stud. I mark where each stud is on the metal LACK hanging hardware and drill new holes using a Cobalt drill bit. The top hole is most important to keep the shelf from bending downward under weight. I drill into as many studs as possible. If the nearest stud is far enough away from one of the rods that holds the shelf that it will move easily when I press down, I use drywall anchors to steady it – but not the awful IKEA ones; get the good ones from any big box store.
