Planning

Storage unit size calculator

Pick the rooms and items you are storing. Cove recommends a standard unit from 5×5 to 10×30 and explains the estimate. You can then look up facilities near a ZIP code or city. The directory does not know which sizes are open.

  1. Step 1

    Count the rooms you are storing

    Count a bedroom, living room, dining room, kitchen, office, or closet only when you are storing most of what is in it. A one-bedroom apartment is usually a bedroom, a living room, and a kitchen.

  2. Step 2

    Add items that are not already in those rooms

    Add sofas, mattresses, boxes, appliances, and vehicles that are not already part of a room you counted. Groups of medium boxes are counted five at a time.

  3. Step 3

    Read the recommended size

    Cove maps the list onto a standard unit from 5×5 to 10×30. The note explains the square-foot estimate. An RV or a boat on a trailer is called out separately because it does not fit in those units.

  4. Step 4

    Look up facilities near a ZIP or city

    Enter a ZIP code or a city to see storage facilities Cove already lists nearby. Cove does not know which unit sizes are vacant. Call and ask for the size you need.

Rooms you are storing

Items not already in those rooms

Medium boxes are counted in groups of five. A car is floor space you cannot stack on.

After you have a size

Price and climate are separate questions

Cove does not publish a price for any unit size. Ask the facility what is due at move-in for the size this calculator suggested, and for the size on either side of it. A larger unit is not automatically a worse fit if the smaller one leaves the sofa outside.

A 10×10 that is climate controlled is a different product from a 10×10 drive-up door. Read climate-controlled versus regular storage before you treat size as the only choice. The full size ladder is also written out at the storage unit sizes guide. What else changes the quote is at what affects a storage unit's price. An RV does not fit these units. That quote is covered at how much RV storage costs.

Questions

What size storage unit does a two-bedroom apartment need?

A two-bedroom apartment, counted as two bedrooms, a living room, a dining room, and a kitchen, lands on a 10×15 in this calculator. A tighter pack can fit a 10×10. A looser pack, or a car added on top, moves up to a 10×20 or larger.

Will a car fit in a storage unit?

A car or small SUV is treated as about 180 square feet of floor that you cannot stack on. On its own that points to a 10×20. Many facilities do not allow vehicles in a standard unit. Ask about door height, indoor versus outdoor parking, and insurance before you reserve.

Where should an RV or a boat go?

An RV, travel trailer, or boat on a trailer does not fit in a 5×5 to 10×30 household unit. Use RV or boat storage for the vehicle, and a separate unit if you also have household goods. Cove's city pages can be filtered to those storage types.

Does this calculator know what is available?

No. It estimates a size from the rooms and items you select. It does not know prices, ceiling heights, or which units are open. The facility list is the same directory as the city pages. Call to check availability.

Do I need a climate-controlled unit?

Ask for climate control when you are storing wood furniture, mattresses, documents, or electronics in a building that is not already indoors and conditioned. Plastic bins and metal tools often do fine in a regular unit. Cove does not know which listed facilities are climate controlled. A longer comparison is at climate-controlled versus regular storage.
