ᐅ How can BILLY shelves be mounted especially securely on a drywall (plasterboard) wall?

Hello everyone,

I am planning to install several BILLY shelves on a drywall partition, as additional storage space is urgently needed. However, I am aware that drywall is not as load-bearing as solid walls, so I place great importance on a particularly stable and secure mounting.

My question to you: Which special fastening methods or materials are best suited to securely fix BILLY shelves to drywall so that they hold firmly and permanently, even under heavy loads (e.g., books, binders)?

I am also interested in any recommended techniques that go beyond the usual installation with standard cavity anchors. Any advice on screw positioning, possible reinforcements inside the wall (e.g., use of horizontal or vertical studs), or plastering methods would be very helpful.

Thank you in advance for your expert tips!

Hello Ixtubar,

The main issue with drywall partitions is their limited load-bearing capacity, especially when you want to install heavy items like fully loaded bookshelves.

I always recommend using metal anchors or special toggle anchors designed for drywall, which distribute the load over a larger area of the wall. It is particularly important to mount the shelves directly onto the wall studs (also called “mounting profiles” or “metal studs”), which are usually located behind the drywall. You can locate these with a reliable stud finder or a specialized detector.

The key here is to place the screws so they engage the wooden or metal studs, not just hold in the drywall, because cavity anchors alone are not reliable for long-term heavy loads.

Regarding positioning: The top bracket of the shelf should be secured with at least two screws directly into a stud, while additional supports can be fixed in the drywall using high-quality ribbed anchors (e.g., Fischer DUOPower).

If the wall is very thin, you can also mount a wooden batten behind the shelf to better distribute the load.

I hope this helps you.

Hello Ixtubar,

your question makes sense, and here is a structured approach for securing BILLY shelves to drywall:

1. Preparation:
- Use a stud finder or profile detector to locate the metal or wooden studs.
- Mark the exact positions of the studs.

2. Fastening materials:
- Use toggle anchors (metal anchors) for areas between studs, if necessary.
- Preferably screw the brackets directly into the studs: wood screws for wooden beams, metal screws for metal framing profiles.

3. Installation:
- Align the BILLY shelves so that the main load points are secured with at least two screws into a stud.
- For multiple shelves side by side, it is advisable to screw a wooden batten horizontally across several studs, onto which the shelves can be hung. This greatly increases stability.

4. Load distribution:
- Avoid point loads on the drywall. The more the load is distributed across the studs, the better.

A common mistake is relying too much on hollow wall anchors alone, which can loosen over time.

This approach is exactly crucial. I wish you much success!

I agree with that, but I would like to add: BILLY shelves are generally quite light in terms of stability, so mounting them on drywall is not necessarily a problem—as long as you’re not storing overweight items.

Have you checked if the wall actually contains dry, solid metal studs? Using stronger wooden battens can sometimes only be a short-term solution if the supporting framework is unstable and cannot properly bear the load.

That makes sense, but it’s only effective if the wooden batten is securely fastened to the wall studs at multiple points—otherwise, the problem is just shifted to another level.

My recommendation: first inspect the basic condition of the wall to ensure that the installed studs show no damage or looseness. If you can rule that out, I would use metal toggle anchors (e.g., Molly bolts) for the areas between studs, with the main attachments directly into the studs. The wooden batten construction is more like reinforcement for special load cases.

I often see that people rely too much on anchors without considering the wall’s structure.

Hey Ixtubar and all other shelf fans ;-)

I mounted my BILLY shelves on drywall and can share a bit from my experience.

What worked really well for me was the following:

- First, as recommended, I located the metal studs using a stud finder.
- Then I attached an 18 mm (0.7 inch) thick wooden batten to the wall studs, which is slightly wider than the shelf. This way, the load is distributed across several points, reducing stress on the wall itself.
- I then screwed the brackets to the shelf and fixed those into the wooden batten.

The shelf is now rock solid and easily holds binders, folders, and even a few plants ;-)

Exactly, otherwise the batten won’t help at all!

Very important: with drywall systems, it’s not just about the type of anchor, but how cleverly the load is distributed.

Good luck with your project!
