Tell us your home size or the things you're storing and we'll estimate the right storage unit — 5×5 up to 10×30 — with what each size actually holds.
Every result is driven by volume in cubic feet, not floor space — because you stack a storage unit to the ceiling. We estimate the cubic feet of what you're storing, then find the smallest standard unit whose usable volume can hold it.
The recommended size is the smallest unit that fits. If it comes back "packed full," we suggest the next size up so you can actually get to your things. Standard sizes assume an 8-ft ceiling; a few facilities offer taller units.
Caveat: this is an estimate. How well you disassemble beds, nest chairs and stack boxes can shift you a size in either direction. Confirm the interior dimensions and door size with the facility before booking.
| Unit size | Floor area | Volume (8-ft ceiling) | Roughly equals | Typically holds |
|---|---|---|---|---|
| 5×5 | 25 sq ft | 200 cu ft | A large closet | A few boxes, small furniture, and seasonal, dorm or office items — about the contents of a large closet. |
| 5×10 | 50 sq ft | 400 cu ft | Studio / small 1-bedroom | The contents of a studio or small one-bedroom without big appliances — a mattress set, a dresser, and roughly 15–20 boxes. |
| 5×15 | 75 sq ft | 600 cu ft | 1-bedroom apartment | A full one-bedroom apartment with some appliances — sofa, mattress set, a few furniture pieces and boxes. |
| 10×10 | 100 sq ft | 800 cu ft | 2-bedroom apartment or house | The furnishings of a two-bedroom apartment or small house — two bedrooms of furniture, appliances and boxes. |
| 10×15 | 150 sq ft | 1200 cu ft | 2–3 bedroom home | A two-to-three-bedroom home — major furniture, appliances, and the contents of several rooms. |
| 10×20 | 200 sq ft | 1600 cu ft | 3–4 bedroom house | A three-to-four-bedroom house, or a one-car garage's worth of belongings, appliances included. |
| 10×30 | 300 sq ft | 2400 cu ft | 4–5 bedroom house | The largest standard unit — a four-to-five-bedroom house, roughly a two-car garage of contents. |
Those charts show one home size per unit. This adds up the actual cubic feet of what you're storing — including the extra boxes or furniture you list on top of a home — and accounts for whether you need a walkway, so the estimate matches your stuff, not an average.
If you have to reach items in the back you can't pack the cube solid — you lose roughly a third of the space to the aisle. We size up so the unit you rent actually works the way you'll use it.
No. The home sizes already include normal furniture. Only add items in the 'extra' fields if you're storing more than a typical household — like a second sofa, garage overflow, or a pile of extra boxes.
Roughly a two-bedroom apartment or small house — about two bedrooms of furniture, appliances and boxes. See the full size table on this page for what each standard size holds.
They assume the standard 8-foot ceiling and that you stack toward it. Some facilities offer taller units; if yours does, you'll fit a bit more than the estimate shows.
It's a solid starting point built from the major operators' size guides and moving-industry volume tables, but real capacity swings with how well you pack. Treat 'packed full' as a nudge to book the next size up, and confirm dimensions with the facility.
