Choosing the right storage unit size in Sarnia is the first step to a stress-free experience. Rent a unit that's too small, and you're playing a frustrating game of tetris. Rent one that's too large, and you're wasting money.
This guide will help you find the perfect fit for your needs and your budget, with a special focus on common Sarnia storage scenarios.
The Goldilocks Guide: Matching Unit Sizes to Your Life in Sarnia
Here’s a breakdown of the most common storage unit sizes and what they can hold.
📦 5x5 Unit (25 sq ft) - The Closet-Sized Solution
What Fits: Think of a small hallway closet. Perfect for about 10-15 small boxes, a small mattress set, a few small pieces of furniture (like a nightstand or chairs), and seasonal decorations.
Ideal For:
Sarnia students needing to store a dorm room's worth of belongings for the summer.
Storing your seasonal tires.
Clearing out clutter from a spare room or apartment.
Sarnia Tip: This is our most popular size for Lambton College students storing mini-fridges, microwaves, and boxes of books over the summer break.
📦 5x10 Unit (50 sq ft) - The Single Room Saviour
What Fits: The contents of a standard small bedroom. This includes a mattress and box spring, a dresser, a small sofa, several boxes, and appliances like a TV or microwave.
Ideal For:
The contents of a one-bedroom apartment.
Homeowners during a small-scale renovation.
Business owners storing office files, supplies, or inventory.
Sarnia Tip: A 5x10 is ideal for storing your patio furniture and summer gear during Sarnia's winter months, freeing up valuable garage space.
📦 10x10 Unit (100 sq ft) - The Family-Sized Favourite
What Fits: The furnishings of a full one-bedroom apartment, including major appliances, multiple large furniture pieces, and many boxes. You can walk around inside comfortably.
Ideal For:
Storing the entire contents of a one or two-bedroom apartment or condo.
Homeowners during a larger renovation or when staging a home for sale.
Business storage for larger equipment or a significant amount of inventory.
Sarnia Tip: Many Sarnia families use a 10x10 unit as a "seasonal rotation" space, seamlessly swapping out summer and winter belongings.
🚗 10x20 Unit (200 sq ft) - The Garage Alternative
What Fits: The contents of a multi-bedroom house, including large appliances and bulky furniture. Most importantly, it can fit a car, boat, or RV (with careful planning).
What Fits (Vehicle-Specific):
Car, Motorcycle, or ATV: Plenty of room for your vehicle with space to walk around it.
Boat: Can accommodate a small to medium-sized boat on a trailer.
RV/Camper: Perfect for securing your RV during the Sarnia off-season.
Ideal For:
Full household moves or long-term storage during relocation.
Sarnia car enthusiasts, boat owners, and RV adventurers needing secure vehicle storage.
Storing large business equipment or commercial inventory.
Sarnia Tip: This is the go-to solution for storing your pleasure boat from Lake Huron or your RV during the winter. It’s like having a second, highly secure garage.
Your 4-Step Sizing Checklist
Still unsure? Follow these steps:
Inventory Everything: Make a list of all the items you plan to store. Don't forget the big, bulky stuff!
Disassemble What You Can: Take apart bed frames, table legs, and other large furniture. This saves a tremendous amount of space.
Think Vertically: The right way to pack a unit is to stack boxes and furniture to the ceiling. A 5x10 unit holds more than you think if you pack it well.
Create Aisle Space: If you need to access your belongings, remember to factor in a walking path when visualizing the space.
