Storage Unit Size Calculator

Measure your belongings and compare a possible floor layout before you shortlist facilities. Actual dimensions, ceiling height, door width, and inventory vary, so verify the fit directly before reserving.

Plan around the items you actually have

Replace the example items with your measurements in feet. Compare an illustrative floor layout with room for an aisle. This is a planning aid, not a fit guarantee or a check of available units.

Stackable means you have confirmed that two identical items can safely sit one above the other. The planner never stacks furniture with other items. Check load limits, door openings and actual unit dimensions with the facility. Your list stays on this page and clears when you reload.

Start with an illustrative item list

These are sample belongings, not a typical or guaranteed fit for every home. Each button replaces your current list. Then edit every measurement, quantity and stacking choice to match your belongings.

A possible layout for your list

Planning range to compare: 10 × 10 feet to 10 × 15 feet. The lower end has a possible layout under your assumptions; extra space can help with packing and access. This is not a fit guarantee or an availability claim.

4 pieces stacked above matching items. The aisle runs down one side; it does not provide access to every item.

Allow extra clearance for wrapping, irregular shapes and moving items through the door. Items are kept upright and may turn on the floor. The diagram does not test doorway clearance or loading order.
