🗄️ Storage Unit Size Calculator

This calculator computes total volume (cubic feet) = Σ(item quantity × average volume per item). Assumed volumes include a queen bed ≈35 cu ft, a sofa ≈35 cu ft, a dining set ≈60 cu ft, a refrigerator ≈40 cu ft, and a small box ≈1.5 cu ft. For example, 1 queen bed (35) + 1 sofa (35) + 1 dining set (60) + 1 dresser (20) + 1 coffee table (10) + 10 small boxes (15) totals 175 cu ft. Adding a 20% buffer for aisle and access space brings that to 210 cu ft, which fits a 5×10 ft unit (≈250 cu ft capacity) — the next size down, 5×5 at 125 cu ft, would be too small.

Common self-storage industry tiers are 5×5 (≈125 cu ft), 5×10 (≈250 cu ft), 10×10 (≈500 cu ft), 10×15 (≈750 cu ft), 10×20 (≈1,000 cu ft), and 10×30 (≈1,500+ cu ft). A 5×5 fits a closet's worth of small items and a few boxes; a 10×10 fits a studio or one bedroom; a 10×20 fits a full 3-bedroom home; a 10×30 fits a large house's worth of belongings. Facilities often list dimensions differently outside the US, so treat this calculator's cubic-foot output as a planning reference and always confirm exact dimensions and ceiling height with the facility before booking.
