Hello everyone,
I’m facing an issue with my KALLAX back panel. I prepared the panel by cutting it myself, but when finally fitting it into the KALLAX shelf, I ran into the problem that the back panel is too short. Specifically, the cut panel is about 1.5 cm (0.6 inches) too short in height, so it doesn’t align flush at the top, which makes the shelf feel unstable and causes unwanted gaps.
Has anyone experienced this problem? Ideally, I’m looking for a solution that doesn’t require completely remaking the back panel. Is it possible, for example, to stabilize the panel with an additional strip or some kind of extension? Or are there mounting tricks I might have overlooked?
I would really appreciate well-founded tips on damage control, repair, or improvements. Thanks in advance!

Just glue on a neat wooden strip, either color-matched or intentionally contrasting, and fill the gap – this can even become a design feature. Who says backing panels always have to be invisible and perfectly flush? I recommend keeping an open mind about it 🙂
Regarding the technical details:
A KALLAX back panel mainly provides lateral stability. However, if it is missing 1.5 cm (0.6 inches) at the top, the shelf usually remains stable overall, but the visual appearance suffers. The most common approach is to add an extension that fits properly and is professionally secured.
I recommend the following procedure:
- Cut a thinner strip of wood in a matching thickness and color.
- Attach the strip to the upper edge of the back panel using wood glue and additional small screws.
- Finally, sand the edges and, if necessary, paint or stain them to create a consistent appearance.
This is much less effort than making a completely new back panel and ensures both stability and aesthetics.
Alternatively, some home improvement stores sometimes offer suitable cut-to-size pieces, or you can use appropriate plywood sheets as an extension.

I would like to add that the backing panels of KALLAX shelves are made from thick cardboard or particleboard. If the backing panel is too short, extending it with thin plywood or MDF is often the best option, as these materials are sturdy enough and easy to cut.
It is important to sand both the backing panel and the extension strip thoroughly before attaching the extension to ensure a clean joint and good adhesion of the glue.
When assembling, it is advisable to first temporarily secure the extension with clamps to ensure a precise fit. Then, fix it permanently using wood glue and small nails or screws. If the area will not be visible, a few touch-ups with acrylic or wood filler can help.
Another option is to reinforce the backing panel from the inside with mounting brackets – this can be helpful depending on the installation situation.
Feel free to ask if you need more details about the materials or the exact construction.
