How to Choose the Right Storage Unit Size
Choosing the wrong storage unit size costs you money - too small and you will need to upgrade, too large and you are paying for empty space. This comprehensive guide helps you choose the perfect size the first time.
Why Choosing the Right Size Matters
Selecting the appropriate storage unit size is one of the most important decisions you will make when renting self storage. Get it wrong, and you could face:
- Wasted money - Paying for space you do not use every month
- Moving hassle - The inconvenience and cost of transferring to a larger unit
- Damaged items - Cramming too much into a small space can damage belongings
- Access problems - Not leaving enough room to walk through and find items

Step-by-Step Guide to Choosing Your Size
Step 1: Make a Complete Inventory List
Walk through your home or business and list EVERYTHING you plan to store. Include:
- All furniture pieces with approximate dimensions
- Number of boxes (estimate high rather than low)
- Large items like appliances, mattresses, sporting equipment
- Vehicles or large equipment
- Seasonal items you will add or remove throughout the year
Step 2: Measure Your Largest Items
You do not need to measure everything, but measure your biggest items:
- Sofas and sectionals (length, depth, height)
- Beds and mattresses
- Wardrobes and large cabinets
- Dining tables
- Appliances (fridges, washing machines)
- Vehicles (if storing cars, boats, or caravans)
Step 3: Consider Vertical Space
Storage units have vertical space you can use. Items you can stack include:
- Stackable plastic bins and uniform boxes
- Suitcases and bags
- Furniture with surfaces (tables, dressers)
- Appliances as a base for lighter items on top
Pro tip: Bring or install shelving units to maximize vertical space and keep items organized.
Step 4: Add 10-15% Buffer Space
Always choose a unit slightly larger than your minimum requirements. This extra space allows you to:
- Walk through your unit to access items at the back
- Reorganize items as needed
- Add more items in the future without upgrading
- Stack items safely without overcrowding

Money-Saving Tips for Storage Unit Sizing
1. Start Smaller If You Can
With Storage Genie's month-to-month leasing, you can always upgrade to a larger unit if needed. Starting with a smaller size and upgrading costs less than paying for unused space every month.
2. Declutter Before You Store
Sell, donate, or discard items you no longer need. Storing items costs money every month - if you have not used something in 2+ years, consider whether it is worth storing.
3. Disassemble Furniture
Take apart bed frames, remove table legs, and disassemble shelving units. This can reduce the space needed by 30-40% and allow for better stacking.
4. Use Uniform Box Sizes
Same-sized boxes stack efficiently and use vertical space better than random-sized containers. This can save you from needing a larger unit.
5. Pack Smart
Fill boxes completely to prevent crushing when stacked. Use dresser drawers and appliances to store smaller items. Hang clothes in wardrobe boxes to save space.
6. Utilize Furniture Interiors
Store items inside fridges, ovens, washing machines, drawers, and cabinets. This maximizes every cubic meter of your unit.
What If I Choose the Wrong Size?
Do not worry - Storage Genie makes it easy to adjust:
Too Small?
Upgrade anytime: With month-to-month leasing, you can move to a larger unit when one becomes available. Contact your facility manager to discuss availability.
Too Large?
Downsize when ready: If you realize you have too much space, you can move to a smaller unit. You will only pay the difference in monthly fees.
Seasonal Changes?
Some customers upgrade for seasonal needs (storing outdoor furniture in winter, adding holiday inventory) then downsize afterward.

How to Maximize Any Storage Unit Size
Create an Aisle
Leave a pathway down the center or side of your unit so you can access items at the back without moving everything.
Stack Strategically
Heavy, sturdy items on the bottom. Lighter, more fragile items on top. Place frequently needed items near the front.
Label Everything
Label boxes on multiple sides so you can see contents without unstacking. Create an inventory map showing where each category is located.
Use Shelving Units
Freestanding shelves let you organize boxes vertically and keep items off the floor. This improves access and protects against moisture.
Store Furniture Upright
Stand sofas and mattresses on their sides to save floor space. This is especially effective in taller units.
