Storage Unit Size Guide

Small Storage Units

Small storage units actually have a lot of space if you pack them efficiently. If you are packing up a dorm or clearing out storage space in your home, do not be afraid to consider a 5×5 storage unit (the smallest of the industry standard sizes). These can fit up to a full size mattress and a few other large pieces of furniture. After those are in the unit, pack your boxes and bins around your larger items. Other popular items for small storage units include:

  • Small dressers and desks
  • Seasonal clothing
  • Christmas trees
  • Shed tools

Lorain OH small storage units (temperature control): 5×5, 5×6, 5×7, 5×10, 7×10, 5×15 

Penn Hills PA small storage units (temperature control): 5×5, 9×4, 5×10, 5×13, 7×10

Medium Storage Units

You are not always able to bring with you all the contents of your old place to your new place right away in a move. Medium storage units can hold about 2-3 bedrooms’ worth of items, perfect for an apartment or condo renter. While most smaller storage units cannot fit larger mattresses, medium storage units have no restrictions for them and can fit multiple king sizes if need be. They can also store:

  • Water sports vehicles (jet skis, kayaks, canoes, etc.)
  • Small trailers
  • Washer/dryer
  • Bicycles
  • Motorcycles

  • Living room furniture
  • Dining room furniture
  • Patio furniture
  • Shed equipment (lawnmowers, snowblowers)
