What Size Storage Unit Do You Actually Need? A Simple Guide

Choosing a storage unit often starts with one simple question: how much space do I really need?

Renting too small can leave you frustrated and cramped. Renting too large can mean paying for space you don’t use. The good news is that with a little planning, you can confidently select the right size for your situation.

Here’s a practical breakdown to help you decide.

Start With What You’re Storing

Before choosing a unit, make a quick inventory of your items.

Are you storing:

• Seasonal decorations and a few boxes?
• The contents of one bedroom?
• Furniture during a renovation?
• The majority of a home during a move?

Small Units (5x5 or 5x10)

Best for:

• Boxes and totes
• Small furniture items
• Holiday décor
• Business documents
• Sports equipment

A 5x5 unit is similar to a small closet. A 5x10 can typically hold the contents of a small bedroom or studio apartment.

If you plan to store items long-term, review A Guide to Storing Furniture Long-Term to ensure everything stays protected.

Medium Units (10x10)

Best for:

• One to two bedroom apartments
• Multiple furniture pieces
• Appliances
• Mattress sets
• Stacked boxes

A 10x10 unit is one of the most popular sizes because it offers flexibility without excessive unused space.

Large Units (10x15 and Up)

Best for:

• Multi-room homes
• Larger furniture sets
• Business inventory
• Long-term household storage

Think About Access, Not Just Fit

When estimating size, don’t just calculate how tightly everything can fit.

Leave:

• Walking space
• Access to frequently needed items
• Room for additional boxes if needed

Packing strategically can help you maximize every square foot.

Still Unsure? When in Doubt, Size Up Slightly

It’s usually better to have a little extra space than not enough. Proper airflow and accessibility make a big difference, especially for longer storage periods.
