ᐅ How can I securely attach Billy bookcases to drywall (plasterboard) walls?

Hello everyone, I am planning to mount my Ikea Billy bookshelves on a drywall (plasterboard) wall and want to make sure they are really stable and secure, as I will be placing delicate books and decorations on them.

I am unsure about the mounting because drywall walls do not seem as load-bearing as solid walls. Are there proven methods or special anchors that are particularly suitable? Should I pay attention to certain maximum weight limits, or is additional reinforcement of the wall recommended?

I would appreciate practical tips on mounting Billy bookshelves on drywall walls – preferably with advice on materials, tools, and how to avoid common mistakes. Thanks in advance!

Hello Famiti,

I’m happy to give you a clear overview of how to securely mount Billy shelves on drywall:

1. Load check: A single fully loaded Billy shelf can weigh between 40-60 kg (88-132 lbs) depending on size and load. The drywall alone usually cannot support this weight.

2. Anchor choice: Make sure to use special hollow wall anchors (e.g., toggle bolts or metal anchors) that expand behind the drywall. Standard plastic expansion anchors are not suitable.

3. Wall mounting: If possible, locate the wooden studs behind the drywall using a stud finder and screw directly into them. This will provide the highest load capacity.

4. Alternative reinforcement: If there are no wooden studs or they are spaced too far apart, you can reinforce the wall by attaching a wooden batten across it.

5. Screws: Use longer screws that penetrate at least 50 mm (2 inches) deep into the anchor or support.

6. Step-by-step:
- Position the shelf.
- Mark the mounting holes.
- Drill holes with the correct diameter for the anchors.
- Insert the appropriate hollow wall anchors.
- Screw the shelf firmly in place.

Common mistakes include underestimated anchor size and using the wrong screws or drill bits.

I hope this helps!

Hello, I recommend cavity toggle anchors for drywall. If possible, screw into the framing behind it. That will hold securely.

Alternatively, you can also use special heavy-duty anchors designed for drywall panels. It is important to fully expand the anchors.

As an addition: The maximum load-bearing capacity on drywall with good toggle anchors is usually around 30 kg (66 lbs) per fastening point. For Billy-style shelving units, the load is distributed across at least two or preferably four points.

Without direct attachment to the wall studs, large-area wall reinforcement is advisable. Experts recommend installing a wooden batten or metal profile behind the wall covering, which is secured to the wall with suitable anchors and then serves as the base for the shelf.

The screws should have a minimum diameter of 5 mm (0.2 inches) and be at least 50–70 mm (2–2.8 inches) long to ensure maximum anchoring in the anchor.

Thanks, that’s a useful tip. Unfortunately, my wall has only 60 cm (24 inches) spacing between the wooden studs, and I need to mount the shelf in the middle. Is there a way to attach such a wooden board firmly and securely so I can mount the shelf on it? How heavy can the board be, and what is the best way to fix it myself?

Also, are regular drywall anchors sufficient for the wooden board, or do I need special cavity anchors for this?
