How to Determine the Right Storage Unit Size

Choosing the right storage unit size is one of the most important steps when renting a self-storage unit. Selecting a unit that is too small can make it difficult to fit your belongings, while a unit that is too large may cost more than necessary. Choosing the right unit size from the start can also help you avoid common storage mistakes that cost renters time and money. We at BLTD manage several locations providing  storage units in Nashville , self-storage facilities in Deltona, located at  1381 Howland Blvd.  or  2969 Howland Blvd , as well as  storage units in Palm Bay, Florida . Be sure to check which one is near you and which will fit your storage needs.


Here’s a guide to help you determine the perfect storage unit size at Storaway Self Storage.

1. Take Inventory of Your Items

Start by making a complete list of everything you plan to store. Include furniture, boxes, seasonal items, and any specialty belongings like bicycles or appliances. Knowing exactly what you need to store will make it easier to determine the appropriate unit size.

2. Consider the Layout of Your Items

Think about how your items will be arranged inside the unit. Tall items can be stacked to save space, and boxes can be organized efficiently if they are uniform in size. Proper planning of your layout can help you choose a slightly smaller unit while still fitting all your belongings. Planning your layout in advance makes it easier to organize your storage unit efficiently and maximize every square foot.

3. Common Storage Unit Sizes and Uses

  • 5x5 Unit:  Suitable for small items like boxes, seasonal decorations, or a few small pieces of furniture.
  • 5x10 Unit:  Ideal for a small room’s worth of belongings, such as furniture, appliances, and boxes.
  • 10x10 Unit:  Fits the contents of a one-bedroom apartment, including large furniture and appliances.
  • 10x20 Unit:  Can accommodate the contents of a multi-bedroom home, including large furniture, appliances, and boxes.
  • 10x30 Unit:  Large enough for a multi-bedroom house, vehicles, or business inventory.

4. Account for Future Needs

If you anticipate acquiring more items while your unit is rented, consider choosing a slightly larger size to allow room for growth. This can prevent the need to upgrade your unit prematurely.

5. Consult Storage Experts

When in doubt, speak with the team at Storaway Self Storage. They can help you assess your inventory and recommend the best unit size for your needs. Many facilities also allow you to upgrade if necessary, providing flexibility for changing storage requirements. Determining the right storage unit size ensures your belongings fit comfortably, remain organized, and help you avoid unnecessary costs.
