By Melissa MillerDecember 21, 2025

When it comes to maximizing space and keeping your home organized, IKEA's storage cubes are a popular and versatile solution. But with so many sizes to choose from, selecting the perfect fit for your needs can be overwhelming. Let's break down the various sizes of IKEA storage cubes to help you make an informed decision.

First, it's essential to understand that IKEA offers storage cubes in two primary series: KALLAX and TROFAST. Each series has unique dimensions and features, catering to different storage requirements.

IKEA KALLAX Storage Cubes

The KALLAX series is known for its modern, minimalist design and ample storage capacity. It's available in various configurations, including 2x2, 2x4, 2x6, and 2x8 cubes, as well as a combination of 1x1 and 4x4 cubes.

KALLAX 2x2 Cubes

Each cube has an internal dimension of 36 cm (W) x 36 cm (D) x 33 cm (H), providing ample space for storing books, toys, or decorative items.

KALLAX 2x4, 2x6, and 2x8 Cubes

The larger KALLAX configurations (2x4, 2x6, and 2x8) share the same depth and height as the 2x2 cubes but have varying widths:

2x4: 100 cm (W)
2x6: 150 cm (W)
2x8: 200 cm (W)

These larger configurations offer more storage space and can be used as room dividers, media consoles, or bookcases. The internal dimensions for each cube remain the same as the 2x2 configuration.

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
