Renting a storage unit can be a smart solution during a move, renovation, downsizing, or just when you’re short on space. But choosing the right size storage unit is crucial—you don’t want to overpay for unused space or find out too late that your belongings won’t fit. This guide will help you select the ideal unit size based on your needs.
Take Inventory of What You’re Storing
Before you pick a size, make a list of what you plan to store. This helps you visualize the space you’ll need and avoid underestimating.
Include:
- Large furniture (couches, beds, dressers)
- Boxes and bins
- Appliances (washers, fridges)
- Bikes or outdoor equipment
- Seasonal decorations or tools
Tip: Group items by type and stackability to better estimate volume.
Understand Common Storage Unit Sizes
Most storage facilities offer a range of unit sizes. Here’s a quick breakdown of the most common sizes and what typically fits:
5′ x 5′ (25 sq ft)
- Size of a small closet
- Ideal for: Boxes, small furniture, seasonal items, or sports gear
5′ x 10′ (50 sq ft)
- Size of a walk-in closet
- Ideal for: One room of furniture or studio apartment contents
10′ x 10′ (100 sq ft)
- Size of a small bedroom
- Ideal for: One-bedroom apartment including furniture and appliances
10′ x 15′ (150 sq ft)
- Fits contents of a 2-bedroom apartment
- Ideal for: Multiple rooms, larger furniture, or business inventory
10′ x 20′ (200 sq ft)
- Size of a one-car garage
- Ideal for: 3-bedroom home or full vehicle storage
10′ x 30′ (300 sq ft)
- Size of a large garage
- Ideal for: Large homes or multiple vehicles
Consider How You’ll Use the Space
Are you packing the unit to the brim, or will you need access to items regularly?
If you need regular access:
- Leave walkways between rows of boxes.
- Store frequently used items near the front.
If it’s long-term storage:
- Maximize space by stacking and packing tightly.
- Disassemble furniture to save room.
Use a Storage Unit Size Calculator
Many storage websites offer online size calculators. You input your items, and the tool recommends a unit size. It’s not perfect, but it gives a solid starting point.
Pro tip: Ask the facility for help—they often have experience with similar moves and can suggest the right fit.
Pack Efficiently to Save Space
How you pack can significantly affect how much space you need.
Space-saving strategies:
- Stack boxes from floor to ceiling (heaviest on the bottom)
- Store items inside furniture (drawers, dressers)
- Break down beds, tables, and shelving
- Use uniform box sizes for easier stacking
Think About Future Needs
Are you planning to store more items later? Or will this be short-term storage?
If you may add more later:
- Go one size up from your current needs.
- It’s often cheaper than upgrading or renting a second unit.
Conclusion: Plan Smart, Store Smarter
Choosing the right storage unit size starts with knowing what you’re storing and how you plan to use the space. Take a little extra time to plan and pack smart, and you’ll avoid the headache of cramped spaces or wasted money.
