What Size Storage Unit for a Studio Apartment? (2026 Guide)

The short answer

For a typical studio apartment, most renters usually need a 5x10 or 10x10 storage unit.Depending on how much furniture they have and whether they are storing large items like a mattress, couch, desk, or appliances.A lightly furnished studio may fit into a 5x10, while a more fully furnished studio often needs the extra room of a 10x10.

When a 5x10 unit may be enough

A 5x10 unit may work well if the studio apartment has:• Minimal furniture• Fewer large boxes• No major appliances• A smaller mattress• Efficient packing with disassembled furnitureMany renters choose a 5x10 when they are storing only the essentials from a studio apartment and want to keep monthly costs lower.

When a 10x10 unit makes more sense

A 10x10 unit is often the safer option if the studio includes:• A full mattress set• A couch or loveseat• A desk• A dresser• A dining table or extra chairs• Many boxes or bulky household itemsThe extra room can make the move easier and reduce the chance of needing to switch units later.

Why studio apartment storage is easy to underestimate

The biggest mistake renters make is assuming that “studio apartment” automatically means a very small storage unit.A studio may only be one room, but once you include a mattress, sofa, desk, dresser, kitchen items, and boxes, the storage space adds up quickly.

Typical costs for these sizes

In many markets, the sizes most often used for a studio apartment usually cost about:• 5x10 unit: $60 to $120 per month
• 10x10 unit: $100 to $180 per month
The real long-term cost can be higher after insurance, admin fees, and future rate increases are added.

How to choose between 5x10 and 10x10

If you are deciding between these two sizes, focus first on your largest items:• Mattress size• Couch or seating• Number of boxes• Whether appliances are going into storage• Whether you want a tight fit or extra breathing roomIf you are close to the limit, the larger unit is often worth the extra monthly cost.
