Kallax Unit Sizes: A Comprehensive Guide

By Michael BrownDecember 16, 2025

The Kallax unit, a part of IKEA's popular Kallax series, is a versatile storage solution that has gained widespread popularity due to its modular design and affordability. But with so many size options, choosing the right Kallax unit can be overwhelming. Let's delve into the various sizes of the Kallax unit to help you make an informed decision.

Before we dive into the sizes, it's essential to understand that the Kallax series offers two main types of units: the Kallax shelf unit and the Kallax storage combination. The shelf unit is a standalone piece, while the storage combination comes with a combination of shelves and drawers or doors.

Kallax Shelf Unit Sizes

The Kallax shelf unit is available in three different heights and two different depths, providing a total of six size options.

First, let's look at the heights. The smallest Kallax shelf unit stands at 35.4 inches (90 cm) tall, followed by the medium-sized unit at 51.2 inches (130 cm), and the largest at 70.9 inches (180 cm).

Height Options

The height of the Kallax unit determines the amount of vertical space it occupies. The smallest height is ideal for shorter spaces or when you want to create a low, horizontal layout. The medium height is perfect for standard room heights, while the largest height is great for high ceilings or to create a dramatic, tall storage solution.

For example, the 35.4-inch tall Kallax unit is perfect for a child's room or a small apartment, while the 70.9-inch tall unit can make a bold statement in a large living room or home office.

Depth Options

Next, let's consider the depth of the Kallax unit. The standard depth is 11 inches (28 cm), while the deeper option is 15.75 inches (40 cm). The depth you choose depends on the amount of storage space you need and the available wall space.

The standard depth is great for smaller spaces or when you want to create a streamlined, minimalist look. The deeper option provides more storage space and is ideal for larger rooms or when you need to store bulkier items.

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
