Use a home as your starting point, or add your own inventory. If you use both, the larger estimate wins.

Compare all seven starting sizes. Actual room shapes, ceiling heights and door openings vary between stores.

Illustrative 25 square foot unit floor plan; actual dimensions vary

25 sq ft

A few stacks of boxes, a bicycle and a small piece of furniture. People often compare it with a large cupboard or a garden shed, but ceiling height and how tightly you pack change what fits.

The contents of a studio, or a room of boxes plus a sofa or a bed, if the rest of the flat is travelling with you or being sold.

How the estimates work →

A little more clarity

Good questions.
Straight answers.

Are these square feet exact?

No. The room starting points and the item allowances are a planning heuristic used on this site. Packing, ceiling height and whether you leave an aisle all change what fits. Treat the suggestion as a place to start, then look at the store’s own size guide.

Should I take a larger unit if I need to get at things?

Usually yes. A unit packed to the door is cheaper per square foot and awkward to use. If you will visit often, leave a path, which means more floor area than a tight pack of the same goods.

What if the total is over 200 square feet?

The tool stops at 200 square feet, which is the largest step in this guide. Ask a provider about a larger unit or two units. Two smaller units are sometimes easier to access than one very full one.
