The right-sized storage unit is helpful for clearing clutter, storing seasonal gear, and even running certain businesses. What size storage unit do I need to make that happen? Learn how to choose a unit that meets your current and future needs so you don’t have to upgrade to a bigger one down the road.
What Determines the Size of Storage Unit You Need

There are so many factors that affect the size of storage unit you need, including:
- How much stuff you have: The more things you plan to store, the larger your unit will need to be.
- How often you need to access your stuff: If you store seasonal clothes and sports equipment, you want to maintain easy access with racks and clear pathways. However, if you need long-term storage or are making a move, you can pack things in a little tighter.
- If you plan to use the unit for hobbies or work: If you plan to do anything in the unit, such as crafting or working, then you need one with enough space to hold all of your supplies, provide a workspace, and let you move freely around.
- What you are storing and how it is packed: Bulky items like furniture, tools, and equipment don’t stack well and often require a larger unit. Vehicles require an extra-large space with drive-up access.
Each of these may carry more or less weight for you than others, so it’s a good idea to decide ahead of time what is most important to you. Then, you can choose a unit size that accommodates your needs.
Common Storage Unit Sizes
Each facility typically has several units of different sizes for you to choose from. These can vary between companies, although most start at around 25 square feet and go up to several hundred square feet.
Small Storage Units
These units are typically 5 or 6 feet wide by up to 15 feet long with a standard ceiling height. Some units have extra tall ceilings, which allow you to stack items higher and reduce the amount of floor space needed.
Small units are good for storing household goods, smaller items of furniture, several boxes, or the contents of up to a one-bedroom apartment. If the small unit has drive-up access, you can use it for bicycles, a motorcycle, or an ATV if the facility allows indoor vehicle storage.
Medium Storage Units

Medium sizes for storage units are generally 10 to 12 feet wide by 10 to 30 feet deep. They are great for storing the contents of homes up to two or three bedrooms, large furniture items, and estate cleanouts. They can also accommodate bigger ATVs, side-by-sides, and some small boats.
Some people choose medium storage units for a hobby work space. If you plan on using your unit this way, be sure to discuss your plans with the management company since not all storage facilities allow it.
Large Storage Units
The largest storage units are at least 10 feet wide and over 30 feet deep, which is equivalent to a two-car garage. The largest storage units can easily reach 800 square feet. They often have ceilings reaching 14 feet or higher.
These are perfect for holding everything within a four or five-bedroom home, several vehicles, exercise equipment, or a good-sized boat. The largest storage units make an excellent base for repair, construction, and event-planning businesses.
Styles of Storage Units
In addition to several sizes, there are also different types of storage units. Be sure to ask about special features such as the following when making your selection:
- Access: Some units have drive-up access, while others are indoors. Each has pros and cons, so you’ll need to determine which is best suited for your application.
- Climate Control: If you plan to store items that can be affected by extreme temperature swings, such as collectibles or electronics, consider a unit with climate control. However, if you would otherwise store something exposed to the heat and humidity of your garage or a backyard shed, you are probably fine without this added feature.
- Electricity: Storage units sometimes have power outlets and lights, making it easy to find things, keep batteries charged, and run tools. If you are trying to find the size of storage unit you need to run a business, you’ll want to make sure it has power.
While these are some of the more common features available, they are not the only ones to consider. For example, security cameras and coded gate access may be important to you if you plan to store high-value items in your unit.
Tips for Choosing the Right Size Storage Unit

Once you know what to look for and what size units are most common, you can evaluate what size storage unit you need. The following tips will help you narrow your selection.
Take Inventory of Everything You Plan To Store
Taking inventory is the first step in deciding what size storage unit you need. Make a list of everything you plan to store in the unit, noting its size, shape, and stackability. You can then input the information into a storage unit size calculator to find what size will work.
Know Your Budget
Your budget will also be a factor in the decision. You may find that the large unit you want is out of reach financially. Be sure to read your contract carefully and stay up-to-date on state laws about rate increases.
Consider How You Will Use the Unit
How you plan to use a storage unit plays a major role in determining the correct size. If you want to store a car or construction equipment, you will need one that is sufficiently large. Additionally, if you plan to work or conduct a hobby, there should be enough space for your supplies and for you to move around while using them.
