How Much Gravel Fits in a Dump Trailer?

How much gravel fits in a dump trailer is really a question about weight. Most dump trailers can physically hold more gravel than they are rated to carry, because gravel weighs around 2,700 to 3,000 pounds per cubic yard. A common 10,000-pound GVWR utility dump trailer may carry roughly 3 to 3.5 tons of gravel, while heavier 14,000-pound trailers carry more. Always check the trailer’s own payload rating.

Know the ratings

GVWR: the maximum total weight of the trailer plus cargo.
Empty weight: the trailer’s weight by itself, often on the VIN plate or spec sheet.
Payload: GVWR minus empty weight. This is how much gravel you can carry.

Example: a 10,000 lb GVWR trailer weighing 3,000 lb empty has a 7,000 lb payload, or about 2.3 to 2.6 yards of gravel.

Typical capacities

Trailer GVWR	Typical payload	Approximate gravel
7,000 lb	About 4,000 to 4,500 lb	About 1.4 to 1.6 yards
10,000 lb	About 6,500 to 7,500 lb	About 2.3 to 2.7 yards
14,000 lb	About 9,500 to 10,500 lb	About 3.4 to 3.8 yards
16,000 lb	About 11,000 to 12,000 lb	About 3.9 to 4.3 yards

These are rough ranges. Your trailer’s actual empty weight and rating determine the real limit.

Volume of the box

A 6 x 12 foot box with 2-foot sides holds about 144 cubic feet, or 5.3 cubic yards, level full, far more than the payload allows for gravel. With gravel, the load often fills the box only partway. Side extensions add volume for mulch or brush, not for stone.

Don’t forget the tow vehicle

The truck must be rated to tow the loaded trailer, and the tongue weight counts against the truck’s payload. A 10,000-pound trailer usually calls for a heavy-duty three-quarter-ton or larger truck, depending on the model. Check the towing guide for your specific truck.

Loading tips

Tell the loader your payload limit in tons.
Place the load slightly forward of the axles for proper tongue weight, often about 10 to 15 percent of trailer weight.
Avoid stacking all the weight at the very front or rear.
Tarp the load as required.
Check tire pressure and lights before leaving.

Weigh it if unsure

Many quarries and scrap yards have scales. Public truck scales at truck stops are another option. Weighing confirms you are within limits.

Bottom line

A dump trailer’s gravel capacity is set by its payload, GVWR minus empty weight, not by box size. A 10,000 lb GVWR trailer often carries about 2.3 to 2.7 yards of gravel. Confirm ratings for the trailer and tow vehicle, load slightly forward of the axles, and weigh if in doubt.

Questions people ask

How many tons of gravel can a dump trailer hold?

It depends on payload. A 10,000 lb GVWR trailer often carries about 3 to 3.75 tons.

How many yards of gravel fit in a 6x12 dump trailer?

The box may hold over 5 yards by volume, but weight usually limits gravel to about 2 to 3 yards.

How do I find my trailer’s payload?

Subtract the trailer’s empty weight from its GVWR on the VIN plate.

What truck do I need to tow a loaded dump trailer?

Often a heavy-duty three-quarter-ton or larger truck. Check your truck’s towing and payload ratings.

Can I overload a dump trailer a little?

Overloading strains tires, axles, brakes, and hitches and can be illegal. Stay within the rating.
