Moving Truck Size Calculator
Determine the exact box truck size (10ft, 15ft, 20ft, or 26ft) and cubic feet capacity needed based on home rooms, furniture, and box count.
Calculated Transportation Estimates
Household Cubic Volume & Truck Sizing Formula
Required Capacity = Base Room Cubic Volume + (Box Count × 3.5 cu ft) + Bulky Furniture Buffer (15%); Compare to Usable Truck Dimensions- 10–12 ft Truck: ~400 cu ft usable capacity (Studio apartment, college dorm, 1–2 rooms of light furniture).
- 15–17 ft Truck: ~760 cu ft capacity (1–2 bedroom apartment, small townhome, standard appliance loading).
- 20–22 ft Truck: ~1,015 cu ft capacity (2–3 bedroom home, sectional sofas, multiple mattresses, patio sets).
- 26 ft Commercial Truck: ~1,680 cu ft capacity (3–5 bedroom house, large garage workshops, max non-CDL payload).
- Stacking Factor: Realistic DIY packing rarely achieves 100% density; maintaining 80%–85% space efficiency prevents en-route shifting.
Step-by-Step Worked Example
Calculation Steps:
- Base 2-Bedroom Furniture Volume = 850 cu ft
- Box Volume Adjustment = 70 boxes × 3.5 cu ft = 245 cu ft
- Bulky Furniture Buffer (15% on 850 cu ft) = +128 cu ft
- Total Estimated Cargo Volume = 978 cu ft
- Recommended Size: 20-ft Box Truck (1,016 cu ft capacity · 96% utilization)
How to Use This Calculator
- 1Select your home size from studio to 4+ bedroom home.
- 2Enter your estimated box count if known (average: ~20–30 boxes per room).
- 3Check whether you have oversized sectional sofas, king beds, or large appliances.
- 4Check the recommended truck length, cubic capacity, and space utilization percentage.
Assumptions & Limitations
- Items are packed in stackable moving boxes with proper furniture disassembly.
- Truck capacities reflect standard domestic rental fleets (U-Haul, Penske, Budget).
Frequently Asked Questions
What happens if I rent a moving truck that is too small?
If your rental truck is too small, on a local move you will be forced to make multiple round trips, burning extra mileage fees and gasoline. On a one-way long-distance move, having an undersized truck is catastrophic, forcing you to rent an additional towing trailer, hire emergency movers, or abandon personal property.
