RoenzoHello everyone,
I plan to mount several IKEA Billy bookcases on drywall partitions in my apartment. Since the walls are obviously not solid, I’m concerned about the stability, especially when heavy books or decorative items will be placed on them. My questions are:
1. Which mounting methods and anchors are best suited to securely attach Billy bookcases to drywall?
2. Is it always advisable to install additional reinforcement behind the drywall, such as wooden battens or special backing panels?
3. Is there a maximum load per shelf to consider when the bookcase is mounted on a non-load-bearing wall?
I’m looking forward to your experiences and tips, especially advice on how to avoid common mistakes and ensure the shelves are safe and won’t break off under load.
Thank you in advance!

For mounting BILLY shelves on drywall partitions, I recommend the following approach: Use heavy-duty anchors (e.g., metal anchors or specialized cavity anchors) with sufficient load capacity. Regular expansion anchors are generally not suitable for heavy loads.
Additional reinforcement, such as pre-drilling and attaching wooden battens to the back of the drywall, is advisable if the shelves will carry heavy weight. These battens allow the shelf brackets to be screwed directly into the wood, significantly improving stability.
The load per shelf should not exceed 15-20 kg (33-44 lbs) without extra reinforcement. For heavier loads, it is advisable to reinforce the walls from both sides or use alternative methods.

I would like to go into a bit more detail here because the stability of BILLY shelves on drywall really depends on several factors.
First, the wall: Drywall generally consists of gypsum board panels mounted on a framework made of wood or metal studs. The type of anchors you use must be precisely matched to the type of wall.
1. Choice of anchors: For gypsum boards without additional reinforcement, hollow wall anchors (e.g., metal Molly bolts or toggle bolts) are the best option, as they expand behind the board and can bear loads. However, these have limited load capacity, usually around 10-15 kg (22-33 lbs) per fixing point.
2. Load distribution: BILLY shelves require multiple fixing points. Using at least three to four anchors per shelf helps distribute the load more effectively.
3. Reinforcement: For heavier loads or larger shelves, cross braces behind the drywall are worthwhile. These are installed from the inside (during new construction or with considerable effort in existing walls) and provide a solid base for screws.
4. Alternative methods: If reinforcement is not possible, consider mounting the shelf only at the front to the wall and bearing most of the weight on the floor.
Very important: Measure the load capacity of your chosen anchors carefully, follow manufacturer specifications, and avoid overloading.
I would also be interested to know the wall thickness and type of drywall, as well as the intended maximum load.

I have 12.5mm (0.5-inch) gypsum plasterboard on metal studs, with a total wall thickness of about 100mm (4 inches). I would roughly estimate the load at 10–15 kg (22–33 lbs) per shelf, usually less, but you never know for sure.

An additional reinforcement, such as pre-drilling and screwing wooden battens on the back of the drywall, is advisable if the shelves are going to be heavily loaded.Could you please explain in more detail how to properly install such a reinforcement? I am a bit hesitant to cut into or open up the wall.
Regarding reinforcement with wooden battens, the following applies:
If access from the inside of the wall is not possible, you can alternatively mount the battens on the surface of the drywall together with the shelf. However, this will increase the distance between the shelves and the wall.
You can screw 20x40 mm (0.8x1.6 inch) wooden battens lengthwise onto the wall and attach the shelf brackets there. It is important that you fix the battens with suitable screws and anchors into the metal studs, if these are accessible, as the metal will best support the load.
If this is not possible, special heavy-duty anchors for metal studs are recommended, which are drilled through the drywall. This often requires drilling with a metal drill bit and some DIY skills.
Another option is to use shelves that are also supported from the sides or from the ceiling, so the load is not carried solely by the wall.
