ᐅ Kallax Shelf No Longer Square After Custom Modification – Any Experiences?

Hello everyone,
I recently bought a Kallax shelf unit from IKEA and wanted to modify it according to my needs to make it more functional. In doing so, I changed the external dimensions and added some additional shelves inside. Unfortunately, I noticed that after the modifications, the shelf no longer has a perfectly square shape – the sides appear distorted, and it doesn’t sit completely flat anymore. My question to you is: Have you had similar experiences when you modified a Kallax yourself?
I am especially interested in what measures you took to restore the shape’s stability or if you found this acceptable. Are there any specific tips on what to consider during modifications to avoid such deformations?
I look forward to a constructive exchange, thanks in advance!

I would like to add a brief note:
The sequence of assembly should not be underestimated either. If you install too many screws too early, the board may begin to warp in the wrong direction anyway. Patience is a virtue here.
Thermal conditions also play a role—humidity in the room affects particle boards, especially during renovations, since the protective layers are interrupted.
You could almost say that Kallax is only truly square and stable in its original condition, since Ikea manufactures for mass production and not for custom building. But of course, building it yourself is the goal 🙂
What is the current status on your end?

Thanks for all the great tips and suggestions so far, I have at least taken most of them into account:
- I have actually screwed everything firmly in place, and the anchors are correctly installed.
- I replaced the back panel with a sturdier MDF board.
- Wood glue was also used during assembly.
I think my biggest weakness was initially altering the external dimensions without installing enough reinforcements. I still completely lack fine adjustments.
I will definitely try that; maybe it will help stabilize the shape.
Any other suggestions on how to measure accurately to ensure the shelf is exactly at a 90-degree angle? I sometimes find that difficult to judge.
Thanks again to everyone!

Finally, a few woodworking tips: You can clamp the shelf overnight with clamps while the wood glue sets

Hi Eric,
From my own experience, I can say that it is always a challenge to achieve precise 90° angles for such large shelves, especially after modifications. What helped me was using a machinist square, which is very accurate, or a digital level with a laser.
The method of diagonal measurement (measuring the diagonals of a rectangle to check if they are equal in length) is also very effective. If the diagonals are equal, you have a right-angled floor plan.
Sometimes small deviations are hardly visible, but they become immediately noticeable when leaning against a wall or installing doors. Therefore, precise work is worthwhile.
If you have any questions about measuring methods, feel free to ask.

The diagonal method is invaluable. If you have trouble getting the shelf perfectly square, it helps to loosely assemble the individual parts first and then check them step by step, rather than tightening everything immediately.
Once you adjust everything with a few clamps and secure it, you can gradually proceed with the final screwing.
I know it takes time and patience, but in the end, this approach definitely ensures the correct shape.
Good luck with your project!
