Choosing the Right Storage Unit Size
Selecting the right storage unit size prevents you from paying for unused space or cramming everything into a unit that is too small. This calculator estimates needed square footage based on your furniture, boxes, and appliances, accounting for stacking and walk-around space.
Standard storage unit sizes range from 5x5 (25 sq ft, like a small closet) to 10x30 (300 sq ft, like a large garage). A 5x10 unit typically holds the contents of a 1-bedroom apartment. A 10x10 fits a 2-bedroom home. A 10x20 can hold the contents of a 3-4 bedroom house.
To maximize space, disassemble furniture when possible, stand sofas and mattresses on end, stack boxes with heaviest on bottom, and leave a center aisle for access to items in the back. Climate-controlled units cost 20-50% more but protect sensitive items from temperature extremes and humidity.
Frequently Asked Questions
What size storage unit do I need for a 2-bedroom apartment?
A 10x10 (100 sq ft) unit is typically sufficient for a 2-bedroom apartment. If you have many large furniture items, consider a 10x15. A minimalist with mostly boxes may fit in a 5x10.
How much does a storage unit cost?
Average costs vary by location: 5x5 units cost $40-$75/month, 10x10 units cost $100-$175/month, and 10x20 units cost $150-$300/month. Urban areas and climate-controlled units cost more.
Should I get climate-controlled storage?
Climate control is recommended for electronics, wood furniture, leather, artwork, photographs, wine, musical instruments, and clothing. Standard units are fine for metal items, outdoor equipment, and sturdy plastics.
How can I reduce the storage unit size I need?
Disassemble all furniture, nest items inside each other (drawers inside dressers, pots inside pots), use vertical space by stacking, and declutter before storing. Selling or donating unused items reduces your storage needs and costs.
