STORAGE UNIT SIZE GUIDE

What fits in each common unit?

Dimensions describe the floor footprint. Cubic-foot figures below assume an 8-foot ceiling, but actual ceilings, doors, columns, and usable space vary by facility.

5×5

25 square feet · about 200 cubic feet

A 5×5 is roughly a generous closet. It works best when most of the inventory is stackable and there is no need for a central aisle.

Often a fit for

  • Seasonal decorations and clothing
  • Several moving boxes or stackable bins
  • Small desk, chair, or narrow shelving
  • Compact sports equipment

Watch for

Door width can rule out large upholstered furniture even when the volume looks sufficient.

5×10

50 square feet · about 400 cubic feet

A 5×10 has the floor area of a small room, usually in a long, narrow shape. Careful loading matters because items at the back can become hard to reach.

Often a fit for

  • Studio apartment or one furnished room
  • Queen mattress set and dresser
  • Small sofa with boxes
  • Bicycle and seasonal equipment

Watch for

Leave a narrow path if you expect to retrieve items before moving out.

5×15

75 square feet · about 600 cubic feet

A 5×15 adds useful depth for a one-bedroom apartment inventory and long pieces. The narrow width still rewards a planned loading order.

Often a fit for

  • One-bedroom apartment contents
  • Bed, sofa, dresser, and boxed belongings
  • Long outdoor or recreational equipment
  • Small appliances and shelving

Watch for

Put items you need first near the door and create a labeled map before filling the back.

10×10

100 square feet · about 800 cubic feet

A 10×10 square footprint is easier to organize than a narrow unit. It is a common starting point for a small two-bedroom move.

Often a fit for

  • Small two-bedroom apartment
  • Multiple bedroom sets
  • Living room furniture and boxes
  • Appliances plus household goods

Watch for

Non-stackable sofas, fragile furniture, and an access aisle consume floor space quickly.

10×15

150 square feet · about 1,200 cubic feet

A 10×15 offers enough width and depth for a fuller two-bedroom inventory or a move with bulky furniture that cannot be stacked safely.

Often a fit for

  • Full two-bedroom home or apartment
  • Several large furniture pieces
  • Major appliances
  • Business stock with a compact aisle

Watch for

Climate-sensitive electronics, wood, documents, and textiles may need climate control.

10×20

200 square feet · about 1,600 cubic feet

A 10×20 is similar in floor area to a one-car garage. It can support a multi-room move and a more usable aisle when packed deliberately.

Often a fit for

  • Three-bedroom household contents
  • Furniture, appliances, and many boxes
  • Renovation storage for several rooms
  • Some vehicles when the facility allows them

Watch for

Vehicle storage depends on exact interior dimensions, door height, turning space, and facility rules.

10×25

250 square feet · about 2,000 cubic feet

A 10×25 gives a large household more room for bulky pieces and makes an access path more realistic than a tightly packed smaller unit.

Often a fit for

  • Large three or four-bedroom inventory
  • Major move with garage contents
  • Large appliances and patio furniture
  • Business inventory requiring access

Watch for

Do not count all 2,000 cubic feet as usable. Safe stacking height and irregular shapes reduce practical capacity.

10×30

300 square feet · about 2,400 cubic feet

A 10×30 is the largest common household unit in the StorageUnit calculator. Very large or awkward inventories may still require multiple units.

Often a fit for

  • Four or more bedroom household
  • Whole-home renovation or major move
  • Large business inventory
  • Furniture plus garage and outdoor gear

Watch for

Compare two smaller units when separate access points or item categories would make retrieval easier.

Size is only one decision

Climate control, drive-up access, floor level, elevator dimensions, gate hours, insurance, and the facility's rate-change policy can matter as much as the footprint. Read how to choose a storage unit, or use the inventory calculator for a personalized estimate.
