Understanding Storage Unit Sizes
Storage units are typically measured in square feet, length by width, similar to a bedroom or small garage. But floor space isn’t the only factor to consider.
Many of our units feature 12’, 14’, and even 16’ ceilings, giving you the ability to pack, rack, and stack safely. That extra vertical space can make a meaningful difference when storing furniture, shelving, or boxed items.
Instead of simply choosing a larger footprint, it often helps to think about how efficiently you can use the full height of the unit.
8’ x 10’ Storage Unit
Best for:
  • Small apartment contents
  • Seasonal items
  • Extra household overflow

An 8’ x 10’ unit typically fits:
  • A couch
  • A mattress set
  • Several boxes
  • Small tables or dressers
  • Bikes or sporting equipment

This size works well if you’re decluttering or storing the contents of a one-bedroom apartment. With proper stacking and shelving, you can comfortably maximize the available space.
10’ x 10’ Storage Unit
Best for:
  • 1–2 bedroom apartments
  • Partial household storage
  • Small renovation projects

A 10’ x 10’ unit can typically hold:
  • Major appliances
  • Bedroom sets
  • Living room furniture
  • Multiple stacked boxes

This is one of the most popular storage unit sizes because it offers flexibility without feeling oversized. If you’re between sizes, this is often the safest starting point.
10’ x 15.5’ Storage Unit
Best for:
  • 2–3 bedroom homes
  • Mid-move transitions
  • Furniture-heavy households

These mid-sized units can typically accommodate:
  • Large sectional sofas
  • Dining room sets
  • Multiple bedroom sets
  • Appliances
  • Dozens of boxes

If you’re storing the majority of a home’s contents, this range gives you room to organize without overcrowding.
10’ x 20’ Storage Unit
Best for:
  • Full household storage
  • Long-term moves
  • Larger furniture layouts

A 10’ x 20’ unit can usually fit:
  • The contents of a 3–4 bedroom home
  • Large appliances
  • Multiple couches and beds
  • Business inventory overflow

For families relocating within Okotoks, South Calgary, or High River, this size provides breathing room during transitions.
12’ x 20’ Storage Unit
Best for:
  • Large homes
  • Combined residential and business storage
  • Long-term storage needs

This option is ideal when you need additional organization space or want to create structured shelving inside the unit. If you operate a small business and need to store inventory, tools, or equipment, this size allows for clean organization while maintaining access pathways.
How to Choose the Right Size Without Overpaying
Before deciding, consider:
  1. Measure Your Largest Items Couches, bed frames, appliances, and dining tables take up more room than you think. Start there.
  2. Think Vertically With taller ceiling heights available, using shelving or stacking properly can reduce the need for a larger footprint.
  3. Leave a Walkway You may need access to certain items before others. Plan for a small aisle if you’re storing long term.
  4. Consider Storage Duration Short-term moves may require tighter packing. Long-term storage benefits from easier access and organization. If you only need storage for a shorter period, ask us about our weekly prices.
If you’re unsure, it’s always better to slightly size up than to overload a unit. Our team can help you compare available sizes and determine the best fit.
