Hello everyone,

I am currently planning to reorganize my home office and have been considering the Billy bookcases from IKEA. However, I have a very specific question: What is the typical load capacity of Billy bookcases?

I am particularly interested in the maximum weight per shelf and for the entire unit under normal everyday conditions, such as when storing books, binders, or somewhat heavier items.

Additionally, I would like to know if there are common weak points that tend to become problematic when loading, and whether certain measures (e.g., additional bracing or shelves made from different materials) can noticeably increase the load capacity.

I would really appreciate detailed information and experiences, including any advice on what to avoid in order not to overload or damage the bookcases.

Thank you in advance!

I am also curious about something else:

How do permanent loads affect the back panel? Some users report that the thin hardboard quickly develops stress and cracks, especially after years of heavy use.

Has anyone had experience with improving the durability of the shelf by reinforcing it with MDF boards or similar materials?

I ask because I highly value long-lasting use in my apartment and do not want to replace shelves frequently.

Yes, that makes sense. The original back panel is often just a thin hardboard sheet, which is mainly important for lateral stability. Reinforcing it with a thicker MDF back panel or even adding diagonal bracing can make the shelf unit overall more rigid.

This helps distribute stresses more evenly and reduces the risk of warping or cracks. As a result, the shelf can hold more weight and remains stable for many years. However, wall mounting is still necessary.

Thank you all very much for the detailed and practical responses!

In summary, the load capacity per shelf is usually around 25-30 kg (55-66 lbs), provided the load is evenly distributed and the shelving unit is properly secured. Through technical measures such as replacing the shelves, adding extra cross braces, or reinforcing the back panels, the load-bearing capacity can be further increased.

This is very helpful for my planning. I will probably have custom wooden shelves made and reinforce the back panels to ensure as much long-term stability as possible.

If anyone has additional useful tips or warnings regarding the load capacity of Billy shelves, I would be glad to hear more.
