Practical storage planning before you compare listings

How the planner works

The calculator starts with a household-size estimate, then adjusts it for furnishing level, common bulky items, sealed moving boxes, a packing buffer, and an optional access aisle. It compares that estimate against common unit capacities from 5 x 5 through 10 x 30.

These inputs are intentionally simple. A useful first decision is usually not a perfect inventory model; it is knowing whether you should begin comparing a 5 x 10, 10 x 10, or 10 x 15 rather than calling every listing from scratch.

See the current formula, coefficients, and validation status.

What StowGauge does not claim

• It does not know the interior shape, height, door size, availability, or condition of a particular provider's unit.
• It does not provide reservations, prices, provider recommendations, or a guarantee that a particular item will fit.
• It does not replace measuring your longest item and checking the access route to the actual unit.

That boundary is deliberate. Storage labels are not standardized enough for a generic tool to promise a physical fit.

Privacy

The planner runs in your browser and does not require an account. When you create a share link, the selected planner values are put in the URL so another person can reopen the same estimate; do not put personal information in those fields.
