ᐅ How do I assemble IKEA BESTA drawers with custom-made inserts?

Hello everyone,
I’m looking for tips and guidance on how to best equip IKEA Besta drawers with custom-made inserts. Specifically, I have the standard BESTA drawers and want to organize them with individually crafted inserts—made from wood or plastic, for example—so they perfectly suit my needs (e.g., cutlery, cables, office supplies). I’m particularly interested in which measurements are crucial, the best ways to secure the inserts without affecting the drawer's function, and which tools or materials have proven effective.
Do you have experience with cutting, measuring, and fixing these inserts? What are common pitfalls? I’m looking forward to concrete advice and examples of how you’ve implemented your custom inserts!

Take precise measurements and cut the components so they fit snugly. You can secure them with wood glue or small screws, as long as the holes don’t interfere with the drawer. Make sure the drawer still moves smoothly and nothing gets stuck.

The main challenge with homemade inserts for IKEA BESTA drawers is achieving precise measurements. The interiors of the drawers often have varying clearances, and the drawer slides must not be obstructed when installing the inserts. Therefore, my advice:

- First, measure the inside dimensions of the drawer very precisely using a caliper, since even a one-millimeter difference can cause problems later.
- It’s best to make the inserts from 6-8 mm (1/4–5/16 inch) thick plywood or MDF, as these materials are sturdy yet still relatively easy to work with.
- Be sure to sand the cut edges cleanly—otherwise, the drawer might stick or the inserts may not fit evenly.
- For securing the inserts: small grooves routed into the side of the drawer or the inserts themselves provide a good grip without needing screws. Alternatively, hot glue or double-sided tape (for plastic parts) offer gentle fastening methods.

Have you considered making your inserts modular? This way, you can adjust the compartments later as your needs change without having to rebuild everything. How many inserts are you planning to make, and what specific uses do you have in mind?

Thanks for the detailed advice! Yes, modular design is definitely a great point. I’m currently planning to outfit three drawers: one for cutlery and kitchen utensils, one for office supplies (pens, scissors, glue, etc.), and a third for electronic accessories like cables, chargers, and batteries.

I especially want to use a modular approach for the office and electronics sections since their contents tend to change more frequently. Did you manage well with groove routings in terms of tools and effort? I only have a simple router, no CNC or anything like that. Are there any important tips for routing grooves into the drawer carcass?

When routing into the BESTA carcass, caution is necessary: the workpieces are often relatively thin and lack solid stability. Therefore, I recommend creating an accurate dimension drawing before routing and using very shallow router bits. To protect the material and prevent splintering, I also like to use painter’s tape to cover the cut edges.

For modular inserts, a classic slot system is suitable, where the inserts are connected through small grooves or slots. This provides stability and allows for easy adjustments.

Important: After installing the inserts, the drawers should still slide in smoothly without resistance. So check all measurements carefully and, if necessary, include small clearances. Before mounting the inserts, I recommend a dry assembly using cardboard or paper as an inexpensive prototype.

Wow, this is a fantastic project! Homemade inserts make the BESTA drawers so much more personal and functional! I cut my inserts from birch wood myself and treated them with waterproof varnish. They look great and feel nice to the touch. Flexible dividers are especially useful for the electronics section since you often want to add new accessories quickly.

My tip: Use magnets built into the inserts so you can easily move or remove the partitions—super flexible! And don’t be afraid of the router: just take it slow and be patient. You can do it!
