ᐅ How can I build IKEA BESTA drawers with internal dividers myself?

Hello everyone,

I am currently working on creating a well-organized storage system using Ikea Besta drawers and would like to build custom internal dividers myself. It is important to me that the dividers are sturdy but also flexible enough to adapt to different uses, whether for small tools, office supplies, or other small items.

I am particularly interested in which materials and construction techniques have proven effective for achieving precise fit, stability, and at the same time, a certain level of modularity. Additionally, it would be helpful if you could share tips on fastening or retrofitting dividers that can be adjusted without major modifications.

How can I build internal dividers for Ikea BESTA drawers myself to create an efficient and durable solution? Looking forward to your experiences and advice!

You can use narrow strips made of plywood or MDF, cut to size, and then clamp them inside the drawer or secure them with small screws. A combination of adjustable dividers, which you can combine with groove strips on the sides, often works better. This way, it remains flexible and stable.

As a general recommendation for DIY interior dividers in Ikea BESTA drawers, consider the following approach:

- Accurately measure the internal dimensions of the drawer (depth, width, height) while paying close attention to existing grooves or rebate profiles
- Choose a suitable material such as 6–8 mm (1/4–5/16 inch) thick MDF or plywood panels that are easy to cut and work with
- Use tongue-and-groove joints or clamping systems to create dividers without permanent screwing
- Optionally, use custom-fit wooden strips or clips for additional fixing

For a flexible solution, individually removable dividers on rails or with magnetic holders can be a practical alternative. Ensure precise workmanship so the dividers fit snugly and do not wobble later.

This is an exciting project with several possible approaches, which I’ll explain in more detail:

First, you should check whether your BESTA drawers have steel sides or simple wooden sides, as this affects how dividers can be installed. Steel sides often lack grooves that make inserting wooden parts easier.

Material selection:
- MDF: very smooth, can be cut precisely, suitable for dividers that will be painted or finished with a wood veneer
- Plywood: highly durable, especially if you plan to store small tools
- Acrylic sheets: for a modern look, but less sturdy

Construction methods:
- Slot system: cut slots along the edges of the divider pieces and fit them together without screws, similar to a slot-together assembly. This requires very accurate measurement.
- Screw-mounted dividers: try using flat brackets or small screws fixed from underneath to hide the screw heads.
- Magnetic dividers: with thin magnets, you can create flexible and adjustable compartments.

Assembly:
- Alignment tools like a center punch or drilling template help ensure all screws are evenly placed.
- When gluing, a small drop of wood glue can be used that still allows later disassembly if needed.

Also consider the load capacity depending on what you plan to store. For heavy items, sturdy partition walls with screws are necessary, while for light office supplies, flexible dividers are sufficient.

If you want me to go through the individual steps or have specific questions, I’m happy to help.

Thank you for the detailed post. My BESTA drawers have steel sides, which makes me a bit cautious. Are there any special techniques to install dividers without much effort despite this?

The magnetic holders idea sounds interesting. What types of magnets work best for this, and how are they best attached when dealing with steel sides?

I also want to avoid damaging the steel sides, so tips for gentle mounting methods would be very helpful.
