ᐅ How can I securely attach Billy-style shelves to drywall?

Hello everyone, I am planning to install several IKEA Billy bookcases on drywall in my apartment. I am wondering how to secure these shelves as safely and stably as possible without damaging the wall or having the shelves fall down. My main concern is the right materials and techniques—specifically, which types of wall anchors are suitable, how many fixing points should be used, and if there are any special tips for load capacity on drywall. Any advice on mounting height or positioning of the fixings would also be helpful. Thanks in advance for your expert tips!

Use hollow wall anchors (toggle bolts) for drywall; they hold well. Use at least four mounting points per side of the shelf board, and if possible, screw them into the wall studs.

For securely mounting Billy shelves on drywall, I recommend using metal cavity anchors, such as toggle bolts or snap toggles, which provide higher load capacity than plastic anchors. It is important to ideally screw the anchors into the wall studs, as these can bear the load much better. The number of fastening points depends on the shelf size and expected load; there should be at least three to four per shelf.

Note: The mounting height does not affect load capacity, but the shelf should be positioned as close to the wall edge as possible to minimize rocking.

If no wall stud can be found, metal toggle bolts effectively bear the load. Space the bolts evenly and never secure them only at the top or bottom.

I think the importance of wall quality is often underestimated. Using only basic toggle bolts quickly limits the load capacity, especially if the Billy shelf is frequently loaded.

three to four per shelf should be the minimum.

A more detailed distinction according to shelf size and weight is missing here.

My tip: If possible, invest in an additional wooden batten as a mounting support, which you attach horizontally to the wall – this distributes the load better and allows you to install more fixing points, even on weaker drywall areas. Exploiting weak spots is too risky otherwise.

Wooden battens provide more stability, yes. Important: Make sure the wall plugs are also approved for the type of wall.
