Hello everyone,

I have a Billy bookshelf from IKEA and would like to add extra shelves. Unfortunately, I can only find original replacement shelves in the store, which are often expensive, and sometimes the dimensions or mounting details are not entirely clear. My specific question: Which replacement parts or shelves fit technically and in terms of mounting exactly (1:1) into a classic BILLY bookshelf? Are there compatible alternatives from third-party manufacturers that are both high quality and precise in fit?

It would also be important for me to know whether the standard dowels or shelf supports are standardized, so that regular shelves can be used with suitable brackets.

Thanks in advance for the tips!

The point raised by theo63 is important:

Incorrectly positioned or oversized drill holes can significantly affect structural stability. Shelf boards usually not only carry their own load but also rely on the side panels of the shelving unit for support. Improper drilling can cause cracks or break-throughs.

How stable are alternative shelves really if you don’t use the original?

High-quality alternative shelves made from solid or high-grade medium-density fiberboard (MDF) coated with melamine perform well. Cheap particleboards can quickly give way, especially under higher loads. Precise drilling according to the original hole pattern is essential.

In your case, if stability and durability are priorities, I would recommend buying the original as a replacement if needed.

For BILLY shelves, I recommend:

- Use original shelves whenever possible.
- Replacement shelves should be 16 mm (5/8 inch) thick.
- Drill holes must be precisely aligned.
- For DIY, use only high-quality MDF boards.

That’s all.
