On the flip side, you shouldn't have to pay for a unit you don't need. So, if you've been wondering about storage unit sizes and which unit you need, here's everything you need to know.

Make sure the facility is well-lit and has a gated entrance and security cameras.

Do they offer packing supplies or a moving and storage service? Some storage will offer services that simplify your moving or packing experience.

Which Size Unit Should You Get? A Guide to Storage Unit Sizes

When it comes to storage unit sizes, you'll find that most self-storage facilities will have a variety of options. From small closet-sized units to large warehouse spaces, there's something for everyone. To help you out, here's a quick guide to the various storage unit sizes:

Small Storage Units

The smallest unit will come in these sizes:

  • 5x5

  • 5x10

The best items to put in small storage units are boxes, small furniture pieces, appliances, holiday decorations, office equipment, and more. If you're a college student and just have a small dorm to pack away, a smaller unit will work perfectly.

Medium Storage Units

For everything in between, a medium-sized unit might work well for you:

  • 10x7.5

  • 10x10

  • 10x15

Medium-sized units are about the size of an average to slightly oversized bedroom. If you're packing up a 1 to 2-bedroom apartment, this is a great option. You can store furniture, large appliances, and all your boxes in one place!

If you own a small business and are looking for a place to store extra inventory, a medium unit should be a perfect fit.

Large Storage Units

For larger projects or if you're moving an entire house, then a larger storage unit is the way to go:

  • 10x20

  • 10x25

  • 10x30

These large units are as big as a one-car garage and can store the contents of an entire house, including furniture, electronics, appliances, and more.

Extra Large

For even bigger projects like commercial storage or storing recreational vehicles like boats or RVs, then extra-large units come in handy:

  • 10x40

Remember, if your belongings will be sensitive to heat or humidity, you should seriously consider a climate-controlled unit. If you're unsure about what belongs in that category, take a look at this blog.
