Hello everyone,

I am planning to fill several Billy bookcases from Ikea with relatively heavy books, including large-format reference works and hefty volumes weighing several kilograms (pounds) per shelf. My specific question is: which Billy bookcase models or versions are best suited for heavy books in terms of load capacity, stability, and durability?

I am interested both in the technical specifications of the shelves and their maximum load limits, as well as practical experience regarding stability when fully loaded. There are often reports of sagging shelves or instability under heavy loads with Billy bookcases.

It would also be helpful to know if there are special reinforcements, accessories, or tricks to increase the load-bearing capacity.

I look forward to precise tips and experiences, preferably differentiated by the common shelf widths and heights. Thanks in advance for your help!

The standard Billy shelves with glass or wooden shelves can hold about 30 kg (66 lbs) per board. For heavy books, it is better to choose the wider models (80 cm / 31.5 inches) and use additional metal supports.

According to the manufacturer, the maximum load capacity of a Billy shelf is about 30 kg (66 lbs) when the weight is evenly distributed. The narrower models (40 cm (16 inches) wide) are less stable than the 80 cm (31 inches) wide versions.

There are reinforced shelves (e.g., from third-party suppliers) made of metal or with metal reinforcements, which are better suited for heavy loads. Additionally, it is recommended to secure the shelf directly to the wall to prevent tipping risks.

I have an 80cm (32 inches) Billy with standard wooden shelves. They creak when I place heavy books on them. Reinforced shelves from third-party suppliers work well.

As an addition: The stability is significantly improved by installing extra screws between the shelves and the side panels. Retrofitting metal brackets also increases lateral stability.

Shelf height also plays a role: For taller units like Billy bookcases, greater emphasis should be placed on wall mounting and additional floor supports to prevent sagging or tipping.

Interesting, do you have a source for that? The 30 kg (66 lbs) probably refers to an ideally distributed load, right? The weight can be very concentrated locally with thick books, causing the shelves to sag more quickly.

That would make sense technically, but isn’t the more than doubled distance between the supports at 80 cm (31.5 inches) compared to 40 cm (15.7 inches) actually a challenge for bending? I suspect that the 40 cm (15.7 inches) wide version sags less precisely because its shorter span is more stable.
