How to Choose the Right Size of a Storage Unit

There are several factors you must consider before selecting the storage unit size. Follow the following steps to make an informed decision based on your specific needs. Here are some steps to follow:

Identify The Main Purpose Of The Storage Facility

Before selecting a storage unit size, identify the primary purpose of the storage space. Are you looking to store household items during a move, archive business documents, or keep seasonal equipment? Understanding the intended use will help you estimate the amount of space required.

Some typical questions to ask of yourself:

  • Will I need to store a boat or other recreational vehicle?

  • Will I require storage space to grow my business inventory?

  • Am I seeking temporary storage during a relocation?

  • Do I need long-term storage of certain items?

  • Will I be regularly rotating items in and out of the storage unit?

Make An Initial Inventory

Make a list of all the items you plan to store. This inventory will give you an idea of the volume and type of belongings you need to accommodate. Categorize the items based on their size, fragility, and any special storage requirements they may have.

Keep the following points in mind while you make your preliminary inventory:

  • Estimate the approximate number of moving boxes or totes that will be stored.

  • Identify the quantity of furniture items intended for storage.

  • If feasible, obtain rough measurements for larger furniture pieces.

Use Painter's Tape To Determine The Sizes Of Storage Units

Measure the dimensions of the storage units you are considering, and then use painter's tape or masking tape to mark off the corresponding size on the floor of a room in your home. This visual representation will help you gauge how much space you need and whether it will comfortably fit your belongings.

Think about the following factors while conceptualizing storage unit sizes:

  • Pay attention to the dimensions listed by the facility, keeping in mind that length and width may be flipped based on the unit's layout and the facility's design.

  • Understand the difference between units with dimensions like 5x10 and 10x5. While they provide the same floor space, one has a shorter length and a longer width, while the other is reversed.

  • Remember to research storage unit sizes and reach out to the facility for any additional questions.

  • Consider requesting a viewing of the unit from the storage manager before finalizing the rental agreement.

If You're Uncertain, Request One Size Bigger

If you're uncertain about the exact size you need, choosing a storage unit that is slightly larger than your estimated requirements is generally advisable. This extra space will provide flexibility and make it easier to access your items without feeling cramped. It's better to have a little extra room than to struggle with a unit that is too small.
