Storage Unit Size Calculator

A one-bedroom apartment typically fits into a 5×10 (50 sq ft) or 10×10 (100 sq ft) unit. The smaller size works for minimal furniture and boxes, while a 10×10 handles a full bedroom set, sofa, dining table, and several boxes comfortably.

A 10×10 unit (100 sq ft) can hold the contents of a one- to two-bedroom home — typically a queen bed, sofa, dining set, dresser, and 20–30 boxes. It's one of the most popular sizes for apartment moves or home staging.

Storage units are measured in square feet (length × width) for floor space, and cubic feet (length × width × height) for total capacity. Most units have an 8-foot ceiling, so a 10×10 unit offers roughly 800 cubic feet of usable space. Our calculator estimates the cubic volume of your items and recommends the appropriate unit tier.

Small units (up to 80 sq ft) suit one room of belongings, seasonal items, or business documents. Medium units (81–150 sq ft) fit two to three rooms. Large units (151–300+ sq ft) accommodate full household moves, vehicles, or business inventory. X-Large units exceed 300 sq ft and can store the contents of a 3–4 bedroom home.

Climate-controlled units are recommended for electronics, wooden furniture, artwork, wine, documents, or anything sensitive to temperature and humidity swings. They cost more but protect valuables from warping, cracking, or mold — especially in regions with hot summers or cold winters.

Stack boxes from floor to ceiling, place heavier items on the bottom, and store furniture vertically where possible (mattresses, sofas). Leave a center aisle for access. Disassemble bed frames and tables to save space, and use the inside of drawers and appliances to pack smaller items.

Yes — vehicle storage typically requires a 10×20 or larger unit (200+ sq ft). Some facilities offer open or covered parking spaces instead of enclosed units, which are more affordable for cars, boats, RVs, and trailers.

This calculator uses standard item volume estimates based on typical furniture and appliance dimensions. It provides a solid starting point, but actual needs can vary based on how efficiently you pack, whether items are disassembled, and ceiling height at your specific facility. When in doubt, size up one tier to ensure everything fits.
