Run a check
Will your KALLAX fit?
Measure smart
What to measure.
Four numbers decide nearly every fit check. Get these right and the rest follows.
- 01The assembled width, depth, and height at the widest points, including feet, handles, and any headboard or back panel.
- 02The flat-pack box dimensions, which is what you actually carry up the stairs and load into the car, not the built piece.
- 03The item's smallest dimension, which decides whether tilting or turning it on edge gets it through a tight opening.
- 04The clear opening of every space on the route, measured to the gap and not the frame, plus diagonal clearance at any turn.
Don't make these
Common mistakes.
Most “it didn't fit” stories trace back to one of these oversights.
- ⚠Measuring the assembled piece when the flat-pack box is what has to clear the door and the trunk.
- ⚠Forgetting that a tall unit close to 80 inches is right at standard door height before trim and flooring eat into it.
- ⚠Assuming a long box fits a sedan trunk when it really needs folded seats or an SUV cargo bay.
- ⚠Planning the doorway but ignoring the turn at the top of the stairs or the landing pivot.

03What is the difference between KALLAX and BILLY?
