Choosing the right storage unit size is the most important decision you'll make when renting storage. Too small and you can't fit everything; too large and you're paying for empty space. This guide will help you pick the perfect fit.

Tips for Estimating What You Need

  1. Make a list of every item you plan to store before visiting facilities.
  2. Think vertical — most units have 8–10 ft ceilings. Stack boxes safely.
  3. Round up — it's better to have a bit more space than to cram everything in.
  4. Climate-control matters for anything heat/moisture-sensitive: wood furniture, electronics, artwork, wine.
