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 estimate from Ikea is that a shelf from the Billy series can hold about 30 kg (66 lbs) with evenly distributed weight. The load capacity strongly depends on the span: 40 cm (16 inches) shelves sag less because the support points are closer together.
Practical tips:
- Use the 40 cm (16 inches) depth shelves for heavier books.
- Reinforce the shelves by attaching metal brackets either glued or screwed underneath the boards.
- For the highest loads, steel shelving or specially reinforced shelves from third-party suppliers are recommended.
Wall mounting reduces the risk of tipping, even with taller shelves.

Thanks in advance for the initial information.
@Sifope, regarding your question: The 30 kg (66 lbs) specification from Ikea can be found in the product information on their website and in the assembly instructions, where the load capacity per shelf is specified.
@Lorukeo: You mentioned that the 40 cm (16 inches) depth is more stable, but my bookshelves are generally 80 cm (31 inches) wide and up to 202 cm (79 inches) tall, as I want to store as many books as possible in a compact space.
Are there any limitations related to the height or number of shelves on how many shelves can be installed before stability becomes an issue?
And does it make sense to combine 40 cm (16 inches) and 80 cm (31 inches) deep models in the same room to optimize what is stored where?
I believe many would agree that a clear recommendation bringing together these considerations would be very helpful.

For tall Billy shelves with heavy loads, I recommend the 80 cm (31.5 inches) wide version. However, wall mounting and additional reinforcements are absolutely necessary.
The maximum number of shelves is harder to specify; generally, the unit can handle up to 5 shelves well, but more becomes critical due to the weight of heavy books.

Are there any restrictions concerning the height or number of shelves,Yes, with Billy, instability can occur when using tall shelves (over 180 cm (70 inches)) without wall anchoring and when fully loaded, especially if many shelves are installed. Five shelves are generally fine, but with each additional one, the weight increases significantly and the risk of sagging rises.

Use wall mounting and additional reinforcements.Absolutely correct. Narrow, stabilizing metal strips or angle irons underneath the shelves are advisable when the weight is excessive.

This is not realistically achievable with heavy books. Alternative support structures beneath the shelves could help, such as additional cross braces under each board. What do others think?
Several points summarized:
- 40 cm (16 inches) wide Billy shelves generally hold heavy loads better due to the shorter span.
- 80 cm (32 inches) wide shelves tend to sag, especially with thick paper and when the load’s center of gravity is concentrated in one spot.
- Wall fixings are mandatory when shelves are heavily loaded.
- Reinforced shelves made of metal or with metal supports are particularly helpful for 80 cm (32 inches) wide shelves.
- The number of shelves affects not only the load capacity but also the overall stability of the unit. A maximum of 5 to 6 is practically recommended.
Conclusion: For heavy books, it is better to choose multiple narrow 40 cm (16 inches) shelves or 80 cm (32 inches) models with verified reinforcements and wall mounting.
