Hello everyone, I am planning to install several Billy shelves on drywall in my apartment. I want to make sure the shelves are securely mounted and can easily support the weight of fully loaded bookshelves without the screws pulling out of the drywall.

My questions are: What fastening materials and techniques are best for safely attaching Billy shelves to drywall? Should I use anchors or special cavity anchors? Are there any recommendations regarding screw size, placement, and load distribution? Tips on preparation, such as locating studs behind the drywall or whether to use additional measures like a backing plate, would also be very helpful.

I look forward to your practical experiences and suggestions.

A brief note on the whole setup: Billy shelves are true classics, but unfortunately, they are not designed for drywall without additional support. :-)

My advice: Find the studs or build a wooden slat frame that you securely attach to the wall with strong anchors. Then you can screw the shelf onto that.

This way, you can enjoy your shelf without worrying it will eventually come crashing down. 🙂

a backing board – a sturdy panel that you attach over a large area with appropriate anchors, and to which you mount the shelf

That sounds interesting – do you or anyone else have more detailed advice on the material and size of such a backing board? Is regular OSB sufficient, or is multiplex plywood better? And how would you recommend securing the board to drywall (plasterboard) walls to reliably support the weight of the shelves?

Regarding your question, Sarkau: For a counterboard, it’s best to use plywood or a high-quality, stable construction timber with at least 18 mm (0.7 inches) thickness. OSB can also work, but it should be a moisture-resistant product that remains sturdy.

For fastening:

1. Use metal hollow wall anchors or metal toggle bolts that spread widely behind the drywall.

2. Screw the board to the wall with multiple anchors, ensuring even pressure distribution across the surface.

3. If possible, secure the board at least in two places directly into wooden studs or metal profiles.

In summary, the counterboard distributes the load over a larger surface area, reducing stress on individual anchors. It is a good compromise when you cannot screw exclusively into studs.

Make sure to choose a board large enough—approximately as wide and tall as the shelf—so the fastening points are sufficiently distributed.
