What Size Storage Unit Do I Need?

 

One of the most common questions is: how much space do I actually need? The answer depends on what you’re storing. Small boxes and seasonal clothing require less space, while furniture, appliances, or vehicles will need larger units.

 

How Tall Are Storage Units?

 

Most storage units are 8 to 10 feet tall, giving you plenty of room to stack boxes, furniture, and equipment. For oversized vehicles or boats, certain facilities offer taller garage-style units.

Small Storage Units

 

Small storage units (5x5 or 5x10) are a great choice if you’re looking for an affordable way to store a limited number of items. Think of them as an extension of your closet or hall storage at home.

  • Common Uses:
    • Seasonal clothing, decorations, or sports gear.
    • Dorm room furniture and boxes for students on summer break.
    • Storing business documents, office supplies, or marketing materials.
    • Bikes, camping gear, or smaller hobby equipment.
  • Benefits:
    • Cost-effective option for those who don’t need a large space.
    • Easy to organize and access quickly.
    • Helps declutter your home or office without committing to a bigger unit.

A small unit is perfect if you just need to reclaim space in your home, prepare for a move, or store valuables that you don’t want in a garage or attic.

 

Medium Storage Units

 

Medium storage units (commonly 10x10 or 10x15) offer more flexibility and can hold the contents of a one- to two-bedroom apartment. These are the most popular sizes for families and renters.

  • Common Uses:
    • Storing furniture during a move or renovation.
    • Temporary storage while downsizing.
    • Business owners storing inventory, tools, or equipment.
    • Keeping large items safe, like mattresses, sofas, appliances, or dining sets.
  • Benefits:
    • Big enough to store entire rooms of furniture.
    • Provides flexibility if your storage needs grow over time.
    • Ideal for medium-term needs, such as life transitions or growing a business.

Medium units are a great balance between cost and capacity. If you’re not sure whether a small unit will cut it, sizing up to a medium gives you peace of mind and extra space to work with.

 

Large Storage Units

 

Large storage units (10x20, 10x30, or bigger) are designed for maximum capacity and flexibility. They are roughly the size of a standard garage or larger, which makes them ideal for both residential and commercial storage.

  • Common Uses:
    • Entire households during a move, remodel, or relocation.
    • Long-term storage for families or businesses with lots of items.
    • Vehicle, boat, or RV storage.
