ᐅ Which shelves are suitable replacements for Billy bookcases?

Hello everyone, I have several Billy shelves with shelves that are now damaged or missing. Since I no longer want to order original replacement parts from Ikea, my question is: Which shelves fit as replacements for Billy shelves, especially from other manufacturers or even from hardware stores? I am looking for shelves with the right dimensions, material thicknesses, and load capacities so that they are stable and fit well into the existing holes. Are there any experiences, tips, or recommendations for alternatives that can be used without any concerns? It is also important to me that the shelves are not too thick so that the doors of the Billy shelves still fit properly. Has anyone installed replacement shelves before and can offer recommendations?

The original shelves are about 1.8 cm (0.7 inches) thick and 40 cm (16 inches) deep (for a standard Billy). For replacements, I have often used MDF panels with a thickness of 18 mm (0.7 inches). These need to be cut to the correct size, and you have to drill the holes for the shelf supports yourself.

As always: enjoying the cutting process is a must 🙂 But seriously, you can definitely use 18mm (0.7 inch) MDF or particleboard from a hardware store. It’s important to seal the edges with paint or veneer to prevent swelling. And yes, you’ll need to drill the holes yourself – a drilling template is recommended for that.

To thoroughly address the topic of replacement shelves for Billy bookcases, here is a brief guide:
1. Dimensions: Standard shelves are 40 cm (16 inches) deep and come in various widths depending on the case height (e.g., 80 cm (31.5 inches) or 60 cm (24 inches)).
2. Thickness: 16 to 18 mm (0.6 to 0.7 inches) is ideal since the holes for the shelf support pegs (typically 5 mm (0.2 inches) diameter, 37 mm (1.5 inches) from the top edge) are standardized.
3. Material: MDF, particleboard, or plywood are all suitable as long as the surface finish is appropriate (painted, veneered, or laminated).
4. Drilling: If you want to avoid drilling, ready-made alternatives are rarely available. A drilling template is really helpful.
5. Load capacity: With 18 mm (0.7 inches) particleboard, you can expect about 20 kg (44 lbs) per shelf.

In short: sourcing your own shelves, cutting them to size, and drilling the holes yourself is the way to go when original shelves are not available.

I think it’s great that you asked such a detailed question. I once used replacement shelves but underestimated how important precise drilling is for stability. The result was that some shelves became slightly wobbly. If you’re unsure, it helps to practice first with a cheap particleboard. Sometimes it’s also worth using a cutting service at the hardware store – they sometimes help with drilling as well.

This is brilliant—so many people here have already found alternative solutions! 🙂 I replaced my Billy shelves with 18mm (0.7 inch) plywood panels, which I painted myself. They now look even better than before and can support significantly more weight. Tip: Invest in metal shelf supports for added stability! This immediately gives the entire shelving unit a professional touch.
