How to Pick the Right Size Storage for a Studio Apartment
Sep 4, 2026 / Public Storage
What size storage unit is best for a studio apartment?
For most studio apartments, a 5×5 or 5×10 storage unit is a practical choice. A 5×5 works well for seasonal belongings, boxes, and smaller furniture, while a 5×10 can typically accommodate the contents of an entire studio apartment. If you want extra space to walk around your belongings or need frequent access, consider a 5×15 unit.
The right size depends on how much you need to store, how often you’ll access your belongings, and whether you’re storing a few items or your entire apartment.
Key Takeaways
- Storage lockers are best for a small number of boxes, clothing, bags, and seasonal items.
- 5×5 units provide about 25 square feet of floor space and work well as an extra closet.
- 5×10 units provide about 50 square feet and can often hold the contents of a studio apartment when packed efficiently.
- 5×15 units provide about 75 square feet and offer additional room to organize and access your belongings.
- Disassembling furniture and using uniform-sized boxes can help maximize available storage space.
- Leave room to access frequently used belongings instead of packing the unit completely full.
Storage Sizes for Studio Apartments
Studio apartments are compact, which can make it difficult to find space for seasonal clothing, sporting equipment, furniture, or belongings you want to keep while traveling or subletting. Self-storage gives you a place to keep those items without filling your living space.
Storage Locker: Best for a Few Small Items
A storage locker is a compact option for storing a limited number of belongings. Because lockers may have different dimensions and less ceiling height than traditional storage units, they are generally better suited for smaller items.
A storage locker can be useful for:
- Off-season clothing
- Travel bags and luggage
- Small storage bins
- Sports equipment
- Holiday decorations
- Other small household items
Choose a locker when you only need to clear a small amount of clutter from your studio.
5×5 Storage Unit: Best for Closet-Sized Storage
A 5×5 storage unit provides approximately 25 square feet of floor space and is roughly comparable to a large closet or small walk-in closet. The standard unit height can also provide vertical storage space for boxes, bins, and other belongings.
A 5×5 may work well if your studio already has built-in storage, a compact bed, or minimal furniture.
Items that can fit in a 5×5 include:
- Seasonal clothing
- Storage bins
- Small furniture
- A small desk or bookcase
- Sports equipment
- Household items
If you’re primarily looking for an extra closet, a 5×5 is a good place to start.
5×10 Storage Unit: Best for Storing an Entire Studio
A 5×10 storage unit provides approximately 50 square feet of floor space and is one of the most versatile options for studio-apartment storage.
When furniture is disassembled and boxes are packed efficiently, a 5×10 can often accommodate the major contents of a studio, including a bed, dresser, small tables, chairs, boxes, and other household belongings.
A 5×10 can be particularly useful when:
- You’re moving between homes.
- You’re temporarily subletting your studio.
- You’re traveling for an extended period.
- You’re renovating your apartment.
- You want to store most or all of your studio furnishings.
For many studio apartments, a 5×10 offers a good balance between capacity and cost.
5×15 Storage Unit: Best for Easy Access and Extra Room
A 5×15 storage unit provides approximately 75 square feet of floor space. Its additional length can make it easier to organize larger amounts of furniture and leave space for an aisle.
This can be helpful if you expect to visit your storage unit regularly. Instead of having to move several boxes to reach something in the back, you can organize your belongings with an accessible walkway.
A 5×15 can hold the contents of many studio apartments while providing additional space for:
- Bicycles
- Larger furniture
- Extra boxes and bins
- Seasonal equipment
- An access aisle
If easy access is a priority, the extra space of a 5×15 may be worth considering.
Quick Storage Guide for Studio Apartments

Keep in mind: Storage capacity varies depending on the unit’s ceiling height, the size of your furniture, and how efficiently you pack. When in doubt, make an inventory of your belongings and compare it with the facility’s recommended storage capacity.
How to Maximize Space in a Storage Unit
You can often fit more into a storage unit by using vertical space and packing strategically.
Disassemble Furniture
Take apart bed frames, tables, shelving, and other furniture when possible. Store the pieces upright or flat against the walls to free up floor space.
Pack Items Inside Other Items
Use empty space inside furniture and containers. For example, smaller household items can go inside drawers, cabinets, nightstands, or bookcases.
Use Uniform-Sized Boxes
Boxes with similar dimensions are easier to stack securely and can make better use of available vertical space.
Put Heavy Items on the Bottom
Place heavier boxes and sturdier belongings on the bottom of stacks. Keep lighter items on top to help maintain stability.
Keep Frequently Used Items Accessible
If you’ll visit the unit regularly, place items you need most often near the front. Creating a narrow aisle can make it easier to reach belongings without unpacking the entire unit.
Choosing Between a 5×5, 5×10, and 5×15
The best storage size depends primarily on how much you’re storing and how often you need to access it.
- Choose a 5×5 if you need extra closet space or are storing seasonal belongings.
- Choose a 5×10 if you need to store most or all a typical studio apartment’s furnishings.
- Choose a 5×15 if you have more belongings, larger furniture, or want additional room to move around inside the unit.
Before renting, measure larger furniture and make an inventory of everything you plan to store. This can help you avoid paying for more space than you need—or discovering that your unit is too small after you’ve moved everything in.
