Before we dive into the specific sizes, it's essential to understand that the Kallax is available in several configurations.

I wanted that custom built-in look without the $3k price tag, so I used what I already had, added a pine countertop, pocket holed everything together, and used leftover plywood for the face frame + doors. Budget builds for the win. 🙌🏼 The best part? No one believes it’s IKEA until I tell them. If you’ve been scared to try an IKEA hack, this is your sign. | Built by Bec | Facebook

Kallax Combinations: Mix and Match

One of the standout features of the Kallax is its modular design. You can combine different widths and heights to create a storage solution that's tailored to your needs. For example, you could create a tall, narrow unit by combining a 40 cm wide Kallax with a 120 cm high Kallax, or you could create a wide, low unit by combining two 100 cm wide Kallax units.

Mixing and matching Kallax units allows you to create a storage solution that's both functional and aesthetically pleasing. It also means that you can adapt your storage solution as your needs change over time.

Using Kallax as a Room Divider

The Kallax's modular design also makes it an excellent room divider. By combining several Kallax units, you can create a physical barrier between two spaces while still allowing light and airflow to pass through. This can be particularly useful in open-plan living spaces or in smaller homes where creating distinct rooms is challenging.
