Choose a Rental Truck Size (Without Guessing)

U-Haul, Penske, Budget, Enterprise. Cube math instead of bedroom math.

Every rental company has a chart that says things like "15 ft truck fits a 2-bedroom apartment."Like storage unit charts, these numbers are vague guides at best. Pick the wrong size and you're either making two trips or paying for space you don't need.

The right way to pick a truck is the same as picking a storage unit: start with your actual inventory, not your bedroom count.

How Do You Get a Real Inventory Number?

Call a moving company and ask for an estimate with weight (lbs) or volume (cubic feet). Quick conversion for household goods:

1 cubic foot ≈ 7 lbs.

So 7,000 lbs ≈ 1,000 cu ft. 3,500 lbs ≈ 500 cu ft.

How Do You Match Inventory to a Truck Size?

Here's what actually fits, assuming tight packing (~85% of the cargo cube). Numbers below are averages across U-Haul, Penske, Budget, and Enterprise for that length class.

Truck LengthUsable cu ftWeight FitTypical Home
Cargo van~200up to ~1,400 lbsStudio, dorm, single room
10-12 ft~340up to ~2,400 lbsSmall 1-bedroom apartment
15-17 ft~640up to ~4,500 lbs1-bedroom, small 2-bedroom
20-22 ft~935up to ~6,550 lbs2-bedroom, small 3-bedroom
26 ft~1,445up to ~10,100 lbs3 to 4-bedroom house

Assumes ~85% packing efficiency. Real rental trucks vary a bit by brand, but the differences are small within a length class.

Which Truck Length Should You Rent?

The big four rental fleets don't all offer the exact same sizes. If you're landing between sizes, shop around.

  • U-Haul: cargo vans, 10 ft, 15 ft, 20 ft, 26 ft
  • Penske: 12 ft, 16 ft, 22 ft, 26 ft
  • Budget: 12 ft, 16 ft, 22 ft, 26 ft
  • Enterprise: 12 ft, 15 ft, 20 ft, 26 ft (availability varies by location)

A Few Things the Calculator Doesn't Capture

  • Heavy-dense loads(workshop tools, books, gym equipment) can hit the truck's weight limit before you fill the cube. Check the payload rating.
  • Tall items (tall dressers, wardrobes, standing lamps) need vertical clearance. Most rental cargo boxes are 7 to 8 ft tall.
  • Loading angle matters. A ramp at a loading dock is different from a steep driveway ramp at your house. Plan for dolly access.

Frequently Asked Questions

Straight answers to the questions we hear most.

A 20 to 22 ft truck holds about 935 usable cubic feet, up to roughly 6,550 lbs, which fits a 2-bedroom or small 3-bedroom home. Rather than trust the bedroom count, get a weight or volume estimate from a mover and match it to the truck. When you land between sizes, go one size up.

For household goods, 1 cubic foot is about 7 lbs. So 7,000 lbs is roughly 1,000 cubic feet, and 3,500 lbs is about 500 cubic feet. Call a moving company for an estimate in weight or volume, then use that conversion to match your inventory to a truck size instead of guessing from your bedroom count.

Always go one size up from the cube math. An extra $20 to $40 on the rental is cheap compared to making a second trip or leaving items behind, and a half-empty truck is easier to load well than a stuffed one. The big rental fleets do not all offer the same sizes, so if you land between sizes, shop around.

A 15 to 17 ft truck holds about 640 usable cubic feet, up to roughly 4,500 lbs, and fits a 1-bedroom or small 2-bedroom. A small 1-bedroom apartment may only need a 10 to 12 ft truck at about 340 cubic feet. Match your real inventory number to the truck, and go one size up if you are close to the limit.
