Choosing the right size storage unit matters. At Knight Owl Storage – HWY 90, we’ve helped thousands of Mobile residents and local businesses find the perfect fit. Whether you’re storing a few boxes or an entire household, this guide will walk you through how to pick the right unit size, so you don’t overpay or run out of room.

Why Unit Size Matters

Picking a unit that’s too small means you’ll be cramming and may need to move again soon. Picking one that’s too large means paying for space you don’t need. At our HWY 90 location, you’ll find both non‑climate‑controlled storage units and climate‑controlled storage units in a variety of sizes, with flexible terms and trustworthy service.

Typical Unit Sizes and What Fits

Small Units (5’×5’, 5’×10’)

– Ideal for seasonal gear, sports equipment, holiday decorations and off‑season tires
– Great for students or single persons freeing up closet or dorm space
If you’re starting small, ask our team about appropriate sizes and access hours.

Medium Units (10’×10’, 10’×15’)

– Fits the contents of a one‑bedroom apartment: sofa, mattress, boxes and small appliances
– Good for downsizing, staging a home for sale or storing business inventory
At our HWY 90 facility, your unit will be secure and accessible every day.

Large Units (10’×20’, 10’×30’)

– Suitable for a multi‑room home: bedrooms, living room furniture, lawn equipment or a vehicle
– Works well for long‑term projects, business overflow or RV/boat storage (depending on access needs)
Ask about our options and access gates when you have large items.

Climate‑Controlled vs Non‑Climate Options

If you’re storing sensitive items, wood furniture, antiques, electronics or paperwork, our climate‑controlled units are the smart choice. For standard items like boxes, patio furniture and common household things, a non‑climate unit offers great value. 

Extra Services To Make It Easier

At Knight Owl Storage on Highway 90, we go beyond just offering space. We also carry packing supplies so you can get ready in one stop. We’re also a U‑Haul dealer (see our Reserve a U‑Haul page), so moving and storing is simpler.

Tips For Choosing Your Unit

  • Estimate your storage needs by making an inventory list.
  • Visit the facility and visualize how items will stack and move.
  • Consider access frequency: Do you need to access your unit often, or will it be stored long-term?
  • If in doubt, go one size up; it’s always better than running out of space.
  • Ask about promotions and flexible terms.
