  • Inserts are 330 × 370 × 330 mm (W × D × H); the box sold as dimensioned for KALLAX is 330 × 380 × 330 mm. Anything you print or build for a cube: stay under 330 × 330 face and about 370 deep.

  • EXPEDIT (sold until about 2014) used thicker frame panels with the same cube; KALLAX inserts fit both.

How big is a KALLAX cube opening?

IKEA does not publish the interior. Its inserts are 330 × 330 mm at the front and 370 deep, and its KALLAX box 330 × 380 × 330, so the opening is a little over 330 mm square and about 380 deep.

How deep is a KALLAX?

390 mm for every size.
