Hello everyone,

I am planning to replace the shelves of my Billy bookshelf. Since the original shelves have lost some stability and I might want to use cheaper or more durable alternatives, I’m wondering: is it advisable and practical to swap out the shelves on a Billy bookshelf myself? Which types of materials and thicknesses work best without damaging the original supports and fittings too much?

Are there any tips on how to properly prepare the bookshelf for this, and does it make sense to order custom-cut shelves or have them adjusted at a local hardware store? I have some DIY experience but want to avoid costly mistakes or potentially compromising the stability.

Looking forward to hearing your experiences, guides, or recommendations! Thanks in advance.

That’s great that you want to take this on yourself! :-)

A few months ago, I replaced my Billy shelves with sturdier pine boards. You can save a lot if you have the cuts done at the hardware store! Thickness is key: I went with 18 mm (0.7 inches); thicker boards provide more stability. Important: The shelves need to have precisely drilled holes for the dowels, otherwise the unit will wobble.

So: get the cuts and drill the holes with a drill bit for the shelf pins, then assemble. It worked really well and looks much nicer too! Totally doable for anyone comfortable using some basic tools!

Observe the original measurements and mark the hole positions.
Wood panels, 18 mm (0.7 inches), preferably plywood.
Use a drill bit suitable for dowel holes.
Do not overload the shelf.

Good morning,

replacing the shelves of a Billy bookcase requires some technical care to ensure the result remains stable over time. The standard Billy shelves are usually about 16 mm (0.6 inches) thick and made of particleboard with a melamine coating.

For replacements, plywood boards or solid pine wood, at least 18 mm (0.7 inches) thick, are particularly suitable to provide better load distribution. It is very important to transfer the hole positions for the shelf supports precisely. I recommend the following steps:

1. Use the original shelf as a template and carefully mark all drill holes.
2. Use a drill with a bit matching the required size—preferably start with a smaller drill bit for pilot holes.
3. After cutting, sand the edges thoroughly and, if necessary, seal them to prevent water or dirt from penetrating.

It’s important not to overload the bookcase before installing the new shelves and to keep the load limits in mind. One question: What are the dimensions of your Billy bookcase (width, depth), and roughly what do you want to store on it? This will help determine the exact stability needed.

I hope this helps for now!

Simply have the new flooring cut to size at the hardware store and carefully mark the holes. Then drill and install. For standard bookshelves, 18mm (0.7 inches) thick wood is sufficient.

Thanks for the helpful post! About the shelf: it’s the standard version with 80 cm (31.5 inches) width and 28 cm (11 inches) depth. Mainly, I store books, some loose folders, and occasionally longer photo albums, which do add some extra weight.

So the load is rather moderate; I estimate a maximum of 15 kg (33 lbs) per shelf. That’s why more stability seems reasonable to me.

How would you recommend treating the edges? The particleboard is originally coated, but the alternative will probably be oiled wood or plywood panels. Is a clear varnish enough for sealing, or should I use something else?
