ᐅ How can the load-bearing capacity of BILLY shelves be increased?

Hello everyone,
I have a somewhat technical question: I want to increase the load capacity of the shelves in my Billy bookcase because the standard shelves are starting to sag under the weight of many heavy books and binders. I am particularly interested in practical and durable solutions that can be implemented at home without completely rebuilding the bookcase or significantly changing its appearance.
What options are there to improve the load-bearing capacity of individual shelves? Are additional reinforcements advisable, and if so, how should they be installed? Are there specific materials that can be added, or handy tips that have proven effective?
Thanks for your expertise!

Technically, the maximum load capacity of a BILLY shelf is about 15 to 20 kg (33 to 44 lbs), as the particleboard material and construction are not designed for higher loads.
If an increase in load capacity is desired, it is advisable to provide additional support in the middle of the shelf. This can be done with a vertical center support that mechanically prevents bending.
Alternatively, inserting a sturdy aluminum or steel profile on the underside is recommended, as it significantly increases bending strength. It is important that the attachment is secure enough to prevent movement, preferably using small screws countersunk into pre-drilled holes.
Another aspect: The shelf should sit as flat as possible against the back panel to improve lateral stability.
Be careful with screws placed too close to the edge: maintain at least 2 to 3 cm (0.8 to 1.2 inches) of distance to avoid tearing out.

Hey everyone 😃
There’s been a really well-informed discussion here. BILLY shelves and load capacity – a classic topic! I agree with the technical suggestions but would like to add a practical tip:
Years ago, I tried using reinforced glass shelves in my BILLY. Glass is heavy, but when made from thick tempered single-pane safety glass (ESG) about 8-10 mm (0.3-0.4 inches) thick, the shelves can support quite a bit – and look really stylish. Of course, this isn’t cheap or quick to do, but it’s an upgrade both visually and in terms of load capacity.
If you prefer wood, a smart combination of a central support and sturdy crossbeams always helps. Even metal brackets along the side edges, facing inward, can be discreetly hidden and provide a lot of stability.
Always measure carefully beforehand and distribute the load evenly; otherwise, even the best reinforcements won’t help. ;-)

Another tip regarding the center support strip: If you want to keep the appearance intact, there are delicate metal profiles that can be mounted on the back, acting as a reinforcement strip. This is almost invisible and protects against sagging.
It gets even better with a combination of metal profiles installed underneath, running perpendicular to the depth, along with the center support strip, which acts vertically.
It is also important that the shelves are not subjected to point loads but that the load is distributed as evenly as possible.
Back to karreo: Have you already checked how much the shelves sag? This helps with selecting the right reinforcement.
