How to use it

  1. Set how many boxes, sofas, beds, wardrobes, appliances, tables with chairs and bikes you will store.
  2. Add in cubic metres any other item not on the list.
  3. Read the total volume and the indicative storage unit size.

What it works out and how

Each item type has an average volume assigned: 0.1 m³ per box, 1.5 per sofa, 2 per bed, 1.8 per wardrobe, 1 per appliance, 1.2 per table with chairs and 0.5 per bike. The tool adds everything up and suggests a unit with enough capacity. Bear in mind that units are advertised in square metres of floor; usable volume depends on height and how well you stack.

Frequently asked questions

How do I go from cubic metres to square metres?

Divide the volume by the height you will really stack to, which is usually about 2 metres even if the ceiling is higher.

Should I leave an aisle?

If you will go in to fetch things, yes: keep a central aisle and put what you will not need at the back.

Does flat-packed furniture take less room?

Much less. A dismantled bed or wardrobe can shrink to a quarter of its volume.
