I am currently looking into who among you uses the IKEA KALLAX shelf as a bookcase and what experiences you have had regarding its load capacity and space issues when the shelf is overloaded. Specifically, I am interested in whether the shelf remains stable when filled with too many books or if you have encountered problems such as sagging shelves or damage. It would also be helpful to know the best ways to prevent overloading—such as how to distribute the books, using additional reinforcements, or possibly combining it with other furniture pieces.
Are there any experience-based guidelines on the maximum weight per compartment? Tips for optimal organization of books within the KALLAX compartments would also be greatly appreciated.
Thank you in advance for your detailed feedback!

Hello Thierryke,
Regarding the use of KALLAX as a bookshelf: The shelf is designed for light to medium loads, with a maximum of about 13 kg (29 lbs) per compartment according to IKEA specifications. This is to be understood as a guideline since the shelves are made of MDF and can warp under load.
Overloading often causes the shelves to sag, especially when books are placed directly on the shelf edges and the weight is unevenly distributed. Furthermore, the joints can gradually loosen due to the additional stress. Care should also be taken with very heavy coffee table books.
Tips for optimization: You can install thin wooden boards or sturdy supports under the shelves to increase load capacity. Distribute the books evenly and store larger books on the lower shelves to avoid concentrating the weight in one spot.
Combining with other shelving units or adding bookends inside the compartments also helps prevent overloading and damage.
I hope this clarifies some of your questions. If you need further information, I’d be happy to provide more details.

I would like to take a closer look at the mechanical aspects that are relevant when using the KALLAX shelf as a bookcase.
The shelves consist, as already mentioned, of medium-density fiberboard (MDF) approximately 1.5 cm (0.6 inches) thick. The material is relatively sturdy but not comparable to solid wood shelves, which can become a problem if overloaded. The weight is distributed across the support areas within the compartments and transferred through the side panels and back panels to the construction’s fixing points.
Issues with overloading typically show up as sagging of the boards, which can extend by several millimeters to over a centimeter (half an inch) if the weight is too high or acts for an extended period. Additionally, the back panel can tear or detach from its connections if the pressure becomes too great.
Here are some tips to minimize the risk:
1. Load distribution: Books should not be packed to maximum capacity in one compartment; it is better to spread them evenly across several compartments.
2. Reinforcement: Adding a wooden strip underneath the shelf significantly increases load-bearing capacity. This can be a 2x2 cm (0.8x0.8 inches) piece of pine wood, properly fixed to the underside.
3. Use of metal brackets: In some cases, additional metal brackets help to support the load.
4. Storage: Heavy books should generally be stored at the bottom, lighter ones at the top. This benefits the overall stability.
5. Check the back panel: It should fit tightly, as it substantially stabilizes the KALLAX system.
I am interested in how many compartments you use and the common sizes of books, as this would help improve the assessment.

even distribution of books and storing larger books rather at the bottom

Are there any experience-based guidelines regarding the maximum weight per compartment?
Additionally, I would like to emphasize that the stability of the KALLAX shelving unit also depends on how it is secured to the wall. Especially under heavy load, wall anchoring should not be neglected to prevent tipping hazards.
Furthermore, I recommend not using the shelf solely as a stacking surface but organizing it in a way that considers both accessibility and load distribution. Partition panels or bookends can help by supporting the weight sideways, thereby reducing the stress on the shelves.
If the shelf is heavily overloaded, I would also consider replacing individual shelves with thicker MDF boards or even solid wood planks. This effort is particularly worthwhile if no new purchase is planned.
My experience confirms that proper handling of load limits and targeted reinforcements can keep a KALLAX functional in the long term, even with a large number of books.
