How do you choose the right storage unit size for your home or business?
When booking self storage or looking for a storage facility rental, guessing your unit size can be tricky. People searching for storage lockers near me in Niagara Falls or St. Catharines face two common fears. They worry about renting a unit that is too small, or paying too much for unused space.
According to spatial efficiency guidelines published by the Canadian Self Storage Association (CSSA), renters who take full advantage of vertical ceiling heights typically reduce their required square footage footprint by up to 25% to 30% compared to flat ground packing.
At HJ Storage (5584 Ramsey Road), all our storage units in Niagara Falls, Ontario feature ground-level drive-up access and 8-foot ceilings. Here is our room-by-room guide to help you pick the best unit size for your move.
5 × 8 Drive-Up Unit (40 sq. ft.)
This unit feels like a large walk-in closet. It is ideal for seasonal tools, student moves, camping gear, and extra household items.
10 × 10 Drive-Up Unit (100 sq. ft.)
This space equals half of a one-car garage. It works well for home renovations, apartment moves, or temporary home staging.
10 × 15 Drive-Up Unit (150 sq. ft.)
This size is slightly smaller than a standard garage. It fits multi-room moves, patio sets, appliances, or trade contractor equipment.
10 × 20 Drive-Up Unit (200 sq. ft.)
This size matches a full one-car garage. It holds an entire home or serves as a secure space for self storage for automobile and car parking.
What are the best pro-tips to maximize vertical space in your unit?
Use sturdy boxes from our on-site supply store. Same-size boxes stack neatly into tall towers without falling.
Wrap your couch in moving pads and stand it upright. This simple trick saves up to 15 square feet of floor space.
Leave an 18-inch walking path down the middle. This allows you to reach boxes in the back without emptying your unit.
