What Are The Typical Sizes Of Storage Units?

When looking for the right storage unit, you'll notice that they usually come in a variety of sizes. Here are some of the most common sizes and what items they can fit: 


This unit is the size of a small closet and is a great choice if you need to store seasonal items like holiday decorations or garden tools. This size will also fit a twin-sized mattress, a small dresser, or a few boxes.


This unit is the size of a walk-in closet and can store the contents of a typical bedroom, including a queen-sized mattress, a dresser, a television, and a few boxes.


This unit is about the size of a large walk-in closet and can fit the contents of a larger bedroom, including any sized bed, a dresser and nightstand, a small couch, and some larger boxes.


This unit is half the size of a single-car garage and can fit the contents of two bedrooms or a typical living room, including couches, end tables, a coffee table, a television, and a few larger boxes.

This unit is as large as a one-and-a-half car garage and can fit everything from a larger house, including an entertainment center and plenty of other appliances and furniture.  

Remember, you can stack things vertically in storage units too. This means you can stack boxes on top of each other or on top of furniture to make the best use of the available space. Businesses can take advantage of larger-sized units to meet their storage needs. 

Which Size Is Right For You?

Before you choose a unit, it's important to take a close look at what you need to store. Make a quick list and estimate roughly how much space each of these items takes up. 

This doesn't have to be exact, but it can give you a good picture of what kind of space you need. After all, you don't want to rent a unit that's too big and end up wasting the space you paid for. But if you find that your unit is too small, you can always size up in the future. 

Look for a storage unit facility that can grow with you if your needs change.
