Storage Unit Size Calculator
Calculates the optimal self-storage unit dimensions (5x5, 5x10 walk-in closet, 10x10 average bedroom, 10x15 two bedrooms, 10x20 one-car garage, 10x30 multi-bedroom house) based on inventory volume in cubic feet and standard 8-foot ceiling heights.
Formula
Unit Size = Floor Area Sq Ft × 8 ft Ceiling; Monthly Rent = Base Sq Ft × ($0.95 to $1.65/sq ft)
1. Standard Unit Dimensions & Volumes: - 5x5: 25 sq ft / 200 cu ft (Fits 20 boxes, chair, small dresser) - 5x10: 50 sq ft / 400 cu ft (Fits queen mattress set, couch, 35 boxes) - 10x10: 100 sq ft / 800 cu ft (Fits 2 full bedrooms, appliances, 65 boxes) - 10x15: 150 sq ft / 1,200 cu ft (Fits 3 bedrooms, patio set, 90 boxes) - 10x20: 200 sq ft / 1,600 cu ft (Fits standard car or 4-bedroom house) - 10x30: 300 sq ft / 2,400 cu ft (Fits large estate home) 2. Monthly Rent: Climate-controlled = ~$1.45/sq ft/mo; Drive-up = ~$1.05/sq ft/mo

Worked example
Storing 2 bedrooms of furniture and 65 boxes during a transition.
Outcome: Recommended unit size is 10 ft × 10 ft (100 sq ft / 800 cu ft volume). Accommodates 2 queen mattresses, sofa, dining table with chairs, TV, and up to 65 stacked boxes while leaving a center walking aisle. Estimated monthly rent: ~$145 to $175/month.
When is a climate-controlled storage unit strictly required?
Climate control is essential for solid wood furniture (which warps/cracks in humidity swings), leather upholstery (which grows mold), musical instruments, electronics, artwork, family photographs, and delicate fabrics.
