Why Choose Our 7' x 20' Storage Units?

✔️More Space for Less Hassle
Our 7x20 units offer about 140 square feet of space — ideal for storing the contents of a 1- to 2-bedroom apartment, business inventory, furniture, or hobby gear. Ceilings are 7' tall.

✔️Perfect for Long or Bulky Items
The extended 20-foot depth makes these units great for couches, shelving, building materials, kayaks, motorcycles, and other long or oversized items.

✔️Simple, Affordable Pricing
No need to shop around or wonder if you're getting the best deal. At Big Box, every storage unit is the same size and the same price — and we promise no rent increases after you move in.

✔️Plan for Easy Access
Store smarter! Stack boxes along the walls, leave a center aisle, and keep frequently-used items near the front for quick, easy access.

What Can You Store in a 7x20 Unit?

  • Household furniture and appliances
  • Business inventory and tools
  • Outdoor equipment and hobby gear
  • Motorcycle and small recreational vehicles (ATVs, dirt bikes, etc.)
  • Seasonal decorations, sports gear, and more

Note: Our 7-foot wide units are not suitable for most cars or full-sized trucks.

Great for RVs, campers, boats, work trucks, and utility trailers.
