Hello everyone,

I am currently dealing with a rather specific issue with the IKEA KALLAX shelving unit: the edges of the shelves stick out by about 2-3 mm (0.08-0.12 inches), which unfortunately affects the overall appearance. It doesn’t look neat or professionally assembled, even though everything was put together correctly.

Has anyone here experienced overhanging edges with KALLAX shelves? I am wondering what the best way to improve the look is without removing the shelves or buying expensive accessories. Are there any handy tips or craft techniques to conceal or make the overhang look more appealing?

I would really appreciate any practical advice or even professional solutions.

Thanks in advance!

Hello kimru,

You have described the problem very clearly, thank you for that. Overhanging edges on KALLAX shelves are a common issue, especially considering the typical panel thicknesses of 15mm (0.6 inches) or the simple tongue-and-groove joints.

Basically, it depends on the construction of the shelves: when the shelves are inserted “crosswise,” the edges often do stick out a bit. A common professional trick is to gently round off the overhanging edges with fine sandpaper or a small file to make the transition less sharp.

Alternatively, you can use thin veneer strips or self-adhesive edge banding, which are available at hardware stores and can be applied to the protruding edges. This not only improves the appearance but also protects against chipping.

It is important to always work carefully and gently to avoid damaging the material.

Best regards, nubar

Hello kimru,

I would like to build on what nubar said and go into more detail about the basics, as this is often overlooked with the KALLAX.

The overhanging edges usually occur because the shelves are slid into the side profiles, which are slightly wider – so the overhang can also be due to the design. Is this the case for you?

If so, the most important question is: How stable do you need the shelf to be? Because overhanging edges can often be reduced by sanding, but this only works if it doesn’t compromise stability.

A very good method, if appearance is important: Glue a thin “edge” of wooden strips (plywood or furniture-grade strips about 2 mm (0.08 inches) thick) to the overhanging edges with wood glue, sand it smooth, and then finish with acrylic paint or clear varnish. This creates a clean line that is less noticeable than an overhanging edge.

If you like, I can also provide you with a step-by-step guide on how to do this best.

Best regards!

Exactly, the shelves are installed crosswise, meaning the longer side of the boards runs along the depth of the shelf. The overhang is mainly visible at the front edge; at the back, everything fits flush.

That sounds interesting, but could you explain exactly what you mean? Are you suggesting adding a strip onto the overhanging edge to visually “thicken” or visually align it?

I want to keep the shelf as original as possible, so I’m hesitant about adding anything. Are there also solutions that reduce the overhang instead of increasing it? For example, by sanding it down or something similar.

I would appreciate more details, thanks to both of you!

Hello everyone,

I would like to go into more technical details here because there are several points to consider carefully before modifying KALLAX shelves:

1. Material thickness and composition
KALLAX shelves are almost always made of particleboard with a white melamine coating. The protruding edges are often somewhat delicate, especially when sanding. If you sand them, you remove part of the melamine layer, making the edge more vulnerable.

2. How much does the edge protrude? Measuring is important here. A 2-3 mm (about 0.08-0.12 inches) overhang is noticeable but not critical.

3. Sanding: If you want to sand, you should use very fine sandpaper (grit 240 or higher) and work carefully but thoroughly. It is best to always sand along the edge.

4. Gluing an edge strip: This may seem counterintuitive to some, but if the edge only protrudes a few millimeters, a thin strip can visually correct this by creating a defined, smooth edge. It is important to match the color of the strip.

5. Alternative: Thin self-adhesive edge banding or even laminate strips made of wood, available at hardware stores or online, are an elegant solution.

One more question for you, kimru: Will the shelf be heavily loaded? This is important because some adjustments could reduce its load-bearing capacity.

I recommend testing carefully on a hidden spot first to avoid any unpleasant surprises.

Best regards!

Thank you for the detailed technical explanation; it helps me a lot. The shelf will be used mostly for decorative purposes and won’t bear much weight, so sanding or edge bonding should be manageable.

I will definitely do that.

Yes, I would appreciate that! A clear guide would be great so I don’t have to experiment and possibly make things worse.

Thanks to you all so far!
