Breaking Down Each Storage Unit Size

5x5 Unit (The “Hall Closet”: This size is perfect for holiday decorations, mattresses, winter coats, small furniture pieces, or boxes of files. • 5x10 Unit (The “Small Room”): An ideal fit for small moves or decluttering a spare bedroom. It comfortably holds a mattress set, a dresser, and a collection of boxes.
10x10 Unit (The “Apartment”): One of our most popular sizes. It can fit the furniture from a one-bedroom apartment.
10x15 Unit (The “Medium Move”): If you are juggling a 1–2-bedroom move, this size offers the extra room needed for larger furniture like sectionals or dining sets.
10x20 Unit (The “Family Move”): This is designed for families or long-term storage needs, accommodating contents from a 2–3-bedroom house and garage items like bikes or lawn equipment. This is the ideal size for storing a vehicle.
10x30 Unit (The “Total Household”): For the large home move or business inventory storage, this provides the maximum space you need to stay organized.


How to Choose the Right Storage Unit Size

Before deciding which size you need, ask yourself these questions:
1. How much are you storing? Take inventory of large items first (beds, couches, appliances). Now is a good time to declutter.
2. Do you need room to walk inside? If you plan to access items regularly, go one size up, as this will allow you the space to make a walkway in the unit.
3. Can you stack items? Using shelving units can both organize your unit and allows you to utilize the vertical space. As an added bonus, this can also reduce the size you need.
4. Are you storing long-term or short-term? If you are storing long-term, consider using a climate-controlled storage unit.
