Hello everyone,
I am currently facing the challenge of fitting IKEA KALLAX shelves with doors in my old building project. The problem is that the walls are not completely straight—some sections of the old wall deviate by several millimeters (a few tenths of an inch), which causes the KALLAX doors to hang noticeably crooked when installed.
My question is:
How can I adjust or install the KALLAX doors in an old building so that they don’t hang crooked or tilt backward despite uneven walls? Are there specific construction steps, mounting materials, or tricks to make the doors appear plumb and visually straight on KALLAX shelves?
I am particularly interested in how to work with angles, frames, or possible shims—or whether it makes more sense to install the doors regardless of the wall condition and compensate for the wall irregularities through other methods.
I’ve done some research, but many instructions assume perfectly straight walls. Thanks in advance for your opinions and experiences!

Hello GUGIBLA,
Regarding the topic of KALLAX doors in older buildings with uneven walls, there are indeed several important factors to consider. Your observation that the doors do not close properly or even hang crookedly due to uneven walls is very typical in older constructions, where wall surfaces often deviate several degrees from vertical.
Basically, I recommend aligning the KALLAX frame as plumb and level as possible on a flat surface before installing the doors. You should do this using a spirit level and small shims or spacers to adjust precisely. Only after this should you attach the door hinges.
Another important step is to avoid screwing the hinges directly into the back panel of the unit if this surface is uneven. Instead, you can use small wooden strips or special hinge plates that allow adjustments to accommodate the wall’s angle — this way you can fine-tune the doors so they close straight.
I also suggest using hinges with adjustable joints, so you can make minor adjustments later on. Unfortunately, IKEA KALLAX doors often come with only simple hinges, so sometimes upgrading is necessary.
Regarding the wall: If the wall is significantly uneven, it makes sense to build a simple adjustment frame from wooden battens to support the door side where it closes, preventing the door from hanging unsupported or warping.
My last question: How much does your wall deviate on average? Only a few millimeters or several centimeters (inches)? This will determine which measures are appropriate.

Hello GUGIBLA,
I can only agree with Filippos’ explanations and add a few points. For older buildings, it is almost always advisable to opt for installation methods that allow flexible adjustments. The KALLAX modules themselves are usually quite stable, but the doors are often the real issue when dealing with uneven surfaces.
A tip: definitely use adjustable hinges, which IKEA or hardware stores offer. These allow you to correct the door both in height and depth after installation.
In cases of more significant irregularities, you can also use sealant (a small silicone gap) to visually fit the doors better. It might sound like a quick fix, but it is actually a practical solution.
If you want to fix the KALLAX directly to the wall, first check if it is perfectly vertical (plumb). If not, use wedges or small wooden blocks to align it.
It is also important that the doors do not rub against the wall if the wall is crooked. In that case, it is better to leave a narrow gap – it is hardly noticeable and makes opening and closing easier.
Good luck with your project!

Basically, I recommend that you first align the frame of the KALLAX as vertically as possible and on a level surface before installing the doors.Exactly! I’d like to add a brief step-by-step guide on how to deal with uneven walls:
1. Use a spirit level to align the KALLAX frame without the doors and secure it with shims.
2. Decide where the hinge plates will be positioned, but don’t screw them in right away.
3. Check the gap between the door and frame at several points to adjust the hinges with small spacer pieces or use adjustable hinges.
4. For significantly uneven walls: place wooden strips or thin wooden panels behind the doors as “buffers.” This will prevent uneven installation gaps later on.
5. Finally, check the finishing trims or door stops to ensure the doors don’t catch or jam.
A common mistake is using the walls as a reference instead of aligning the frame properly. The frame and doors need to fit together, not the walls!
Hope this helps 🙂

Especially in older buildings, before installing doors, you should first check the entire piece of furniture for correct dimensions and vertical alignment. The most important point: If you are building on an uneven wall, a more stable wooden frame behind the cabinet is often the best long-term solution.
I also recommend using high-quality hinges with eccentric screws. These allow precise adjustment of the door in all directions after installation.
If the misalignment is very large, slight modifications to the doors, such as rounding the latch edge, can help prevent binding.
This way, you avoid long-term stress on the materials or warping.
