I’m planning to replace the standard particleboard shelves in my old BILLY bookcase with new solid wood to make the shelf more durable and visually appealing. I’m wondering what exactly to consider when using new wood for a BILLY bookcase: Are there specific requirements regarding the type of wood, thickness, or quality so that the shelves can support the weight and remain stable? Do the screws or mounting points need to be adjusted, or should the surfaces be treated differently compared to the original IKEA panels?
I understand that the original shelves are designed and tested for a certain load capacity, but how can I assess which wood would be a good substitute without compromising the load-bearing ability or the fit?
I look forward to your experiences, tips, and any advice on common mistakes to watch out for when working with custom wood for a BILLY bookcase.

Hello Jarrettka,
Your question is quite comprehensive, and I appreciate that you want to understand exactly what matters.
First: The choice of wood is crucial. IKEA typically uses MDF boards with melamine coating or particle boards for the BILLY shelves, which are not solid wood but are very uniform and dimensionally stable. If you want to use new solid wood, you should make sure it does not absorb significant moisture fluctuations – otherwise, it could warp later. Hardwood like beech or ash is more stable but also considerably more expensive. Softwood such as pine can work but tends to crack more easily.
Second: The board thickness is a major factor for load capacity. The original shelves are usually 16 to 18 mm (5/8 to 3/4 inch) thick. If you use thinner wood, this could significantly reduce its strength. Tip: The wider the shelves, the thicker they should be, or you need to add reinforcement underneath the boards.
Third: Screws and fasteners. The original connections are designed for particle boards with dowels and special screws. Solid wood behaves differently – it may hold screws better but also requires pre-drilled holes to avoid splitting. The dowel holes might no longer fit because solid wood is less flexible.
Additionally, surface treatments are recommended to protect the wood against moisture and dirt. Sealing with wood oil or clear varnish makes sense.
I’m curious: What type of wood are you considering, and what tools do you have available? How precisely do you plan to monitor the fits, or do you intend to cut the shelves yourself to exact dimensions?

IKEA mostly uses MDF boards with melamine coating or particle boards for BILLY, which are not solid wood but very homogeneous and dimensionally stable.I also found this to be a major point when I tried it myself. I wanted to upgrade the shelf with real wood boards, but it sometimes feels slightly unstable—especially if the wood is not properly pretreated.

A tip from me: If you use real wood, try to pick wood with as uniform a grain as possible and as few defects (knots, branches) as you can. This makes working with it easier and increases stability.
Are you also asking about surface finish? Because for me, that made a big difference in how the wood feels and how it reacts to moisture.
Hello Jarrettka,
I understand your wish to upgrade the BILLY shelf with new wood and would like to share a few basic points that will surely be useful to you.
First, wood moisture content is really important because wood changes over time. If you are using solid wood, make sure it is properly conditioned (meaning it has the right residual moisture, usually 8-12%), so no warping occurs later.
Considering the wood species is also relevant for the weight—very dense woods may put more strain on the shelf frame.
Another point: make sure all drill holes for dowels and screws fit perfectly. It can help to first test with a sample board or, if in doubt, measure and mark all drill holes on the new wood yourself. With solid wood especially, the risk of cracking is higher if pre-drilling is done incorrectly.
For protecting the wood, I recommend either quality wood oil or clear varnish, depending on whether you want a more natural or glossy finish. A medium to high level of protection is advisable, particularly if the shelf will be touched frequently or placed in slightly humid rooms.
Finally, my advice: take your time measuring and working precisely. IKEA furniture often seems simple, but the fit is very tight. Building it with your own wood means everything has to be exactly right.
If you want more details, feel free to ask again with your exact wood type and intended use.
