Cubic Feet Averages Based On Truck Size

Many consumers are confused about what cubic feet actually looks like — specifically inside a box truck. This matters because several long distance moving companies calculate costs based on how much cubic footage a load takes up.

This guide is beginner friendly. After reading it you'll understand cubic foot averages by truck size, which helps you avoid inaccurate estimates and deceptive price increases based on an alleged cubic footage increase.

How Much Cubic Feet Fits In A Truck

The figures below show cubic foot capacity averages by truck size: 10ft, 15ft, 20ft, 26ft and 53ft.

1) 10 Foot Truck — 380 to 450 cubic feet

A 10 ft truck is one of the smallest moving vehicles and generally holds between 380 and 450 cubic feet. Because of the small capacity, this truck is not a common vehicle for long distance movers.

A 10 foot truck works for small studio moves consisting of mostly boxes and one to three pieces of furniture at most.

2) 15 Foot Truck — 760 to 850 cubic feet

A 15 foot truck is commonly used for short distance moves and generally holds between 760 and 850 cubic feet.

Small long distance loads can use a 15ft box truck with a shipment consisting of a few pieces of furniture and 15 to 20 boxes.

3) 20 Foot Truck — about 1,000 cubic feet

20 foot trucks are common for large 1 to 2 bedroom apartments or a downsized 3 bedroom unit. A 20 foot truck holds roughly 1,000 cubic feet, which is enough for mid-sized shipments.

You can fit a living room set, a bedroom set, dining room furniture, miscellaneous furniture pieces and boxes comfortably in a 20 foot truck. However, a 20 foot truck is not enough space for larger households with oversized furniture, or for people shipping more than basic furniture.

4) 26 Foot Truck — 1,600 to 1,800 cubic feet

26 foot moving trucks are the most common vehicle for household goods long distance relocations. A 26 foot truck holds between 1,600 and 1,800 cubic feet and can load a 3 bedroom or a downsized 4 bedroom. An article we published previously explains why a 26 foot truck may not be enough space for a full 4 bedroom home.

You can fit three rooms of furniture and a living room set comfortably in a 26 foot truck. If you have several additional spaces — a garage, office, den, basement or patio — a 26 foot truck will not fit your entire household. Consider two 26 foot trucks, or relocating with a semi instead.

A note on the numbers you'll see elsewhere: some rental sites claim a 26 foot truck handles a 5 to 7 bedroom home. It does not. That figure assumes minimal furniture and perfect loading. Plan for 3 bedrooms and treat anything beyond that as a bonus.

5) 53 Foot Trailer (18 Wheeler) — up to 4,000 cubic feet

A 53 foot trailer is used for larger households, typically 4+ bedrooms with several pieces of furniture and 100 or more boxes. These trailers hold up to roughly 4,000 cubic feet, meaning all of your items can be transported in one vehicle.

A 53 foot trailer can transport a 4 to 5 bedroom home comfortably, including furniture ranging from basic to oversized. A household shipping in a 53 foot trailer rarely runs into capacity issues, which makes it the go-to option for larger than usual shipments.

Why Your Load Never Fills The Whole Truck

Here's something the published numbers don't tell you: no shipment ever uses 100% of a truck's rated capacity.

Rated cubic footage is a measurement of empty space — length times width times height, corner to corner. Household goods are not rectangular. A sofa has curved arms, a dining table has legs, a mattress flexes, and nothing stacks perfectly against a wheel well.

In practice, a well-loaded truck uses about 80 to 85% of its rated cubic footage. A 26 foot truck rated at 1,700 cubic feet realistically carries around 1,400 cubic feet of actual household goods.

This is also why capacity figures vary between sources. Some publish the raw box measurement, others publish a realistic loading figure. Neither is wrong — they're measuring different things.

Truck Size Doesn't Set Your Price On A Shared Load

This is the part that confuses most consumers, and it's worth being clear about.

If you're moving on a shared load, your belongings ride alongside other households' shipments. Your shipment occupies the same 600 cubic feet whether it's loaded into a 26 foot truck or a 53 foot trailer. You are charged for the space your goods occupy, not for the vehicle they ride in.

So a mover telling you that a larger truck means a higher price is describing a dedicated truck, where you're paying for exclusive use of the vehicle. On a shared load, the truck size is a logistics decision, not a pricing one.

How To Sanity-Check A Cubic Footage Claim

If a mover tells you your shipment grew, these numbers give you a way to check.

Get the inventory in writing before load day. A cubic footage total has to come from somewhere. If the number changes, the inventory should have changed too — ask which items were added.

Use the truck as a visual reference. If your goods fill roughly half of a 26 foot truck, you're looking at about 800 cubic feet, not 1,400. A load that occupies a quarter of the same truck is closer to 400. You don't need a tape measure to notice when a claimed number and what you can see don't match.

Ask how the number was calculated. Cubic foot pricing is legal and widely used, and it isn't a scam on its own. Our guide on weight versus cubic feet estimates explains both methods. The problem isn't the method — it's a number that appears without an inventory behind it.

Remember the 110% rule. On a non-binding estimate, a carrier cannot require more than 110% of the estimated charges at delivery, with any remaining balance billed within 30 days. A cubic footage claim that pushes your bill well past that is not enforceable at your door.

Photograph the load. Before the truck leaves, take pictures of your goods in the truck. If a dispute follows, a photograph of your shipment occupying a third of the trailer is worth more than any argument.
