1. What Factors Determine the Right Storage Unit Size
Before diving into dimensions, consider the following
-
Type and number of items: Are you storing furniture or just boxes
-
Duration of storage: Long-term storage may require more ventilation and accessibility
-
Access frequency: Will you need to walk in and out regularly, or is stackability more important
-
Extra features: Climate control needs, proximity to your location, and business vs personal use
These factors play a vital role in determining the optimal unit size.
