Common Sizes of Storage Units and What They Hold

Explore our guide to the most common storage unit sizes and what you can store inside each one.

5×5 Storage Unit

A 5×5 storage unit is ideal for small items like moving boxes, holiday decorations, or a few pieces of furniture, such as a small desk, chair, or nightstand. It’s about the same size as a standard closet, making it perfect for storing additional belongings from a bedroom, dorm, or home office.

5×10 Storage Unit

Our 5×10 storage units are suitable for holding the contents of a small studio apartment or additional room in your home. You can store a mattress set, dresser, TV stand, and several medium-sized boxes with room to spare. This size is also a great choice for storing seasonal items, sports equipment, or small appliances.

10×10 Storage Unit

A 10×10 storage unit is a good size if you’re moving from a one-bedroom apartment. It can hold large items like a refrigerator, couch, dining table with chairs, and even a bed. You’ll also have room for several boxes of clothes, kitchen items, or books.

10×15 Storage Unit

Do you need more space? A 10×15 storage unit is an excellent choice if you’re storing items from a two-bedroom home. It can hold larger furniture like dressers, coffee tables, and bookshelves. There’s also room for a large TV and boxes of your favorite childhood toys. This storage unit is about the size of a large bedroom, so it’s perfect if you’re moving, downsizing, or need more room for your belongings.

10×20 Storage Unit

A 10×20 storage unit is ideal if you need to store items from a three-bedroom house. It has enough space for large furniture like beds, sofas, and even large appliances like a washer and dryer. You can also include many boxes with clothes and kitchen items.

10×30 Storage Unit

The 10×30 storage unit is our largest standard size and offers quite a bit of space. It’s great if you’re moving from a large house and need to store belongings from couches and appliances to dressers and tables. It’s also perfect if your garage is full and you need more room for tools, bikes, or outdoor gear.

Tips for Choosing the Right Storage Unit Size

One of the best storage tips before picking a storage unit is to make a list of everything you plan to store. This helps you figure out how much space you’ll need.

Don’t forget to think up, not just across, as stacking boxes and using shelves can fit more. If you plan to visit your storage unit often, choose one large enough to allow a small aisle inside so you can easily access your belongings without having to rearrange everything.
