Tight pack
Useful for one move-in and one move-out when dense stacking is realistic.

Worked presets, not bedroom rules
The property-size pages on MoveSize are worked examples generated from the same editable inventory model. Each page shows the furniture and box mix behind the number together with the tight, practical and regular-access outputs. They are not separate calculators with a bedroom count substituted into the same formula.
Use a scenario to understand the starting assumptions, then open the full storage optimiser and change the inventory to match your belongings.
Why storage calculators disagree
Providers often translate cubic contents into floor area using different assumptions about stacking height and access. MoveSize shows more than one scenario rather than presenting a single number as universally correct.
Practical
A balanced starting point with some headroom for awkward shapes and retrieval.
Regular access
Allows more circulation and deliberately sacrifices storage density.
