A 5×10 is 5 ft wide: long pieces such as sofas, mattresses and tables must run lengthwise or stand on end, which uses space less efficiently than the numbers suggest.

Planning estimate that compares volumes, not a 3D packing plan. Check the facility’s actual interior dimensions and door width.

How it works

  1. Tap “Studio” or “1 bedroom” as a starting point, or enter your own item counts.
  2. Adjust stacking height and packing if you need an aisle to reach things.
  3. Optionally enter the monthly prices you were quoted for each size.
  4. Read the verdict, how full each unit would be, and the cost per usable cubic foot.

Formula

Item volume = Σ count × typical cubic feet per item
5×10 usable = 5 × 10 × stacking height × packing factor
10×10 usable = 10 × 10 × stacking height × packing factor
Cost per usable ft³ = monthly price ÷ usable volume

A 10×10 has exactly twice the floor area of a 5×10. With 8 ft stacking and typical (75%) packing that is about 300 ft³ versus 600 ft³ of packed contents. The calculator calls a 5×10 “tight” above 85% full, because the last 15% is the hardest space to use.

Example

A student storing a full bed set, a dresser, a desk and chair, a TV, a bike and 25 medium boxes over the summer was quoted $65 a month for a 5×10 and $110 for a 10×10.

What typically fits in each

A 5×10 is about the size of a large walk-in closet. It usually takes the contents of a studio or a single bedroom: a mattress set, a dresser, a small sofa or chair and 15–25 boxes. A 10×10 is half a one-car garage and typically holds a one-bedroom apartment including a sofa, dining set and a couple of appliances.

Because a 10×10 usually costs well under twice as much as a 5×10, the cost per usable cubic foot is often lower in the larger unit. If your items fill more than about 85% of a 5×10, the extra monthly cost of a 10×10 is often worth the easier loading.

Frequently asked questions

Will a queen mattress fit in a 5×10 storage unit?

Yes. A queen mattress is 60 × 80 in. and stands on its edge along the 10-ft wall. Store it upright in a mattress bag and leave its face clear of heavy items.

Can I fit a one-bedroom apartment in a 5×10?

Sometimes, if the furniture is minimal and you pack tightly to the ceiling. Most one-bedroom apartments with a sofa, dining set and appliances need a 10×10.

Is a 10×10 twice the price of a 5×10?

Usually not. Prices vary by market, but the larger unit is commonly 1.4–1.8 times the price for twice the space. Enter the quotes you received to compare.

How many boxes fit in a 5×10?

About 100 medium (3 ft³) boxes if the unit held boxes only and you stacked 8 ft high with typical packing; with furniture, far fewer.
