ᐅ How can I securely attach Billy shelves to drywall?

Hello everyone,

I’m planning to mount my IKEA Billy shelves on a drywall, but I’m unsure how to do this securely and permanently without the shelves eventually falling down or damaging the wall. The wall is made of standard gypsum plasterboard fixed to a metal stud frame, and I want to use as strong fastening methods as possible since the shelves will be loaded with books and some weight.

What types of anchors or fasteners do you recommend for this setup? Should I pay attention to specific spacing? Are there any special heavy-duty anchors or other techniques that work particularly well?

I look forward to your tips and practical experience, and thank you in advance for the help!

That is a valid concern. The key factor is whether the shelves will be attached only to the drywall or if you have access to the metal or wooden framework behind it.

Heavy-duty anchors for drywall, such as metal toggle bolts or special cavity anchors, can work if they have the appropriate load capacity. However, for heavier loads, you should definitely try to fasten the shelves directly to the studs – this is the more stable solution.

How large are the shelves and what is the approximate total weight you are planning? These factors will help to better assess the safest mounting method.

Thanks for asking! The shelves are standard Billy units measuring 80x28x202 cm (HxWxD), each weighing about 30 kg (66 lbs) on their own. On top of that, there will likely be 40-60 kg (88-132 lbs) of books and decorative items, so about 80-90 kg (176-198 lbs) per shelf in total, spread across several shelves.

The wall is finished on the inside with 12.5 mm (0.5 inch) drywall panels, behind which metal studs are spaced roughly 60 cm (24 inches) apart. Access to these studs is fairly easy, meaning I could use them as mounting points if needed.

I am looking for a system that can reliably support the total weight over the long term while minimizing damage to the wall. I want to avoid constantly worrying about it or having to spend a lot of money later on repairs.

Based on this information, the following can be concluded:

1. Direct fastening into the plasterboard is only suitable for light loads, with a maximum of 10–15 kg (22–33 lbs) per fastening point; otherwise, there is a risk of tearing or breakouts.

2. The safest installation is on the metal studs (the framing). You should try to position the back panel of the Billy shelves so that the screws are driven into the metal studs.

3. Self-tapping metal screws, preferably with a drill point, are suitable for fastening into metal studs, allowing installation without pre-drilling.

4. If the studs are not accessible, cavity metal anchors with toggle mechanisms can be used; however, these have a lower load capacity.

5. Maintain a spacing of at least 60 to 80 cm (24 to 31 inches) between fastening points and place multiple screws at the top and bottom of the shelf to distribute the load effectively.

Recommendation: Screw into the metal studs and position the shelves so that at least 3 to 4 secure fastening points are possible.

I would recommend metal toggle anchors if you cannot access the studs. Otherwise, screw directly into the metal studs using appropriate sheet metal screws. Use screws that are as long as possible and several per shelf.

If the metal studs are accessible, always screw into them. This provides a much stronger hold compared to anchors in drywall panels. Also, use washers under the screw heads to distribute the load more effectively.
