The 10x30 is the biggest standard storage unit most Miami facilities offer — 300 square feet, roughly the size of a two-car garage. It fits a 3-4 bedroom house's contents, a car plus furniture, or a small business's entire inventory. It's also the most expensive unit most people consider — $230-$520/month depending on neighborhood and climate control. This guide covers real Miami pricing, what fits, and when a 10x30 makes more sense than renting two smaller units. Compare 10x30 units across Miami.

What Actually Fits in a 10x30
A 10x30 gives you 300 square feet with an 8-foot ceiling — 2,400 cubic feet total. In practical terms:
- 3-4 bedroom house: full contents including all bedrooms, living room, dining room, kitchen appliances, and garage items
- Vehicle + furniture: one car (parked inside) plus a 1-bedroom apartment's worth of boxes and furniture on the remaining space
- Small business inventory: e-commerce stock, equipment, shelving — enough space to walk between aisles
- Large boat on trailer: some drive-up 10x30s accommodate boats under 30 ft — see our boat storage guide
- Contractor setup: tools, materials, equipment, and a workbench — a mini-warehouse for one operation
What doesn't fit: two cars side by side (you need a 10x40 or two 10x20s), a full 5-bedroom house, or a business operation that needs loading docks. For those needs, consider a
