On average, one cubic yard of decomposed granite weighs between 2,600 and 2,900 pounds, with 2,800 pounds (1.40 US short tons) serving as the most commonly accepted industry benchmark for loose, dry material. However, bulk density is not a static constant: moisture, compaction state, particle gradation, and mineral composition can push that weight as high as 3,100 pounds per yard after heavy rain.
Understanding decomposed granite weight is vital for two primary reasons: first, quarries frequently bill commercial accounts by the ton rather than the yard; second, aggregate is exceptionally dense, and underestimating its payload can quickly overload consumer pickup trucks and utility trailers. If you are calculating a job with complex dimensions, you can use our interactive decomposed granite calculator to adjust bulk density and see exact ton-to-yard conversions instantly.
Decomposed Granite Volume-to-Weight Reference Table
The conversion table below shows estimated weights across various cubic yard volumes based on the typical reference density of 2,800 lbs/yd³ (1.40 US short tons/yd³), alongside metric equivalents.
| Material Volume | Weight in Pounds (lbs) | Weight in US Short Tons | Weight in Metric Tonnes |
|---|---|---|---|
| 0.25 cubic yard (6.75 cu ft) | 700 lbs | 0.35 tons | 0.32 tonnes (318 kg) |
| 0.50 cubic yard (13.5 cu ft) | 1,400 lbs | 0.70 tons | 0.64 tonnes (635 kg) |
| 0.75 cubic yard (20.25 cu ft) | 2,100 lbs | 1.05 tons | 0.95 tonnes (953 kg) |
| 1.00 cubic yard (27.0 cu ft) | 2,800 lbs | 1.40 tons | 1.27 tonnes (1,270 kg) |

Bulk Density vs. Solid Granite Density
A frequent source of confusion when reading geological data sheets is the distinction between mineral density and bulk aggregate density:
- Solid Granite Rock: An unweathered granite boulder or polished kitchen slab weighs approximately 165 to 170 pounds per cubic foot, or about 4,500 pounds per cubic yard.
- Loose Decomposed Granite: Because DG is composed of fractured particles ranging from 1/4-inch gravel down to silt-like rock flour, there are air spaces (voids) between the grains. In an uncompacted truck bed, these air voids represent roughly 35% to 40% of the total volume. Consequently, loose DG weighs substantially less: approximately 100 to 110 pounds per cubic foot (2,700 to 2,900 lbs/yd³).
- Compacted In-Place DG: Once rolled, tamped, and wetted on a pathway, void spaces collapse. In a finished installation, the in-place dry density climbs to approximately 120 to 135 pounds per cubic foot (3,240 to 3,600 lbs/yd³).
This is why ordering loose cubic yards must account for compaction: if you need 1 yard of compacted material, you must order roughly 1.20 to 1.25 loose yards. For details on how this translates to square feet, see our decomposed granite coverage chart.
The 4 Key Factors Influencing Delivered Weight
1. Moisture Content
Moisture is the single largest variable. Dry stockpiled DG in summer typically contains 2% to 4% moisture. After heavy rains or when sprayed for quarry dust suppression, moisture can spike to 8% to 12%. On a 10-ton dump truck load, a 10% moisture gain means you are paying for nearly one full ton of water.
2. Particle Gradation & Fines
Standard landscaping DG is sold as 1/4-inch minus or 3/8-inch minus, meaning all particles pass through a specified sieve, including fine rock dust. Mixtures with higher concentrations of silt and clay pack denser even in a loose state, increasing bulk weight compared to washed or screen-classified pea gravels.
3. Mineralogy & Regional Quarry Source
Granite is an igneous rock comprised of quartz, feldspar, mica, and hornblende. Formations rich in iron oxides, amphiboles, or dense feldspars naturally register higher specific gravities than quartz-heavy or decomposed sandstone blends.
4. Presence of Stabilizing Binders
Premixed stabilized DG contains added organic plant-based mucilage or dry polymeric binders. While the additive weight is small (1%–3% by mass), stabilized blends are blended to specific target moistures at the plant, resulting in consistent delivered bulk weights around 2,850 to 3,000 lbs/yd³.

How to Convert Decomposed Granite: Tons to Cubic Yards
When you receive a quote in tons but your landscape architect drew plans in square feet and inches of depth, use these quick mathematical formulas:
At 2,800 lbs/yd³: US Tons = Cubic Yards × 1.40. Example: 4 cubic yards × 1.40 = 5.60 tons.
At 2,800 lbs/yd³: Cubic Yards = US Tons ÷ 1.40 (or Tons × 0.714). Example: 10 tons ÷ 1.40 = 7.14 cubic yards.
If your supplier bills by the ton, comparing their unit pricing to yard-based rates is easy using our guide on decomposed granite cost per ton and yard.
Can My Pickup Truck Carry One Yard of Decomposed Granite?
In most consumer pickup trucks, the answer is NO.
This is one of the most dangerous misconceptions in DIY landscaping. While the bed of a standard half-ton pickup truck (such as a Ford F-150, Chevy Silverado 1500, or Ram 1500) has physical volumetric space for 1.5 to 2 cubic yards, payload capacity is limited by weight, not bed dimensions.
| Vehicle Class | Typical Safe Bed Payload | Max Decomposed Granite Capacity |
|---|---|---|
| Mid-Size (Tacoma, Ranger, Colorado) | 1,000 – 1,400 lbs | 0.35 to 0.45 cubic yard (max 0.6 ton) |
| Half-Ton (F-150, Silverado 1500, Ram 1500) | 1,500 – 2,000 lbs | 0.50 to 0.65 cubic yard (max 0.9 ton) |
| Three-Quarter Ton (F-250, 2500 Series) | 3,000 – 3,800 lbs | 1.0 to 1.25 cubic yards (1.4 – 1.7 tons) |
| One-Ton Single/Dually (F-350, 3500 Series) | 4,000 – 6,500 lbs | 1.5 to 2.25 cubic yards (2.1 – 3.1 tons) |
*Always check your vehicle's specific driver-side door jamb tire & loading placard for exact Gross Vehicle Weight Rating (GVWR) minus curb weight.
Loading a full cubic yard (2,800 lbs) into a half-ton pickup bottoms out the leaf springs, strains the transmission, and severely compromises braking distances. If your project requires more than 1 cubic yard, having the material delivered in a tri-axle dump truck is significantly safer, cheaper, and more convenient.
Frequently Asked Questions About Decomposed Granite Weight
How many tons are in a yard of decomposed granite?
At an industry-standard bulk density of 2,800 lbs/yd³, there are 1.40 US short tons in one cubic yard. If the material is lighter or drier (2,600 lbs/yd³), it equals 1.30 tons; if damp or heavily compacted, it can reach 1.45 to 1.50 tons per yard.
How many cubic yards are in 1 US ton of DG?
One US ton (2,000 pounds) equals approximately 0.714 cubic yards (roughly 19.3 cubic feet) at the baseline density of 1.40 tons per yard.
How much does a 50 lb bag of decomposed granite equal in cubic feet?
A 50 lb bag of decomposed granite provides approximately 0.48 to 0.50 cubic feet of material. It takes about 54 bags to equal one full cubic yard (27 cubic feet).
Does decomposed granite weigh more than gravel or crushed stone?
Decomposed granite is slightly denser than clean washed gravel of the same mineral source because DG contains fine rock dust and sand particles that fill the spaces between larger stones, leaving fewer open air voids. Clean 3/4-inch crushed gravel typically weighs 2,500 to 2,700 lbs/yd³, whereas DG averages 2,700 to 2,900 lbs/yd³.
How much does wet decomposed granite weigh?
Saturated decomposed granite can absorb 8% to 12% moisture by weight, increasing bulk density from 2,800 lbs up to 3,050 to 3,150 pounds per cubic yard (over 1.55 tons per yard). Always request delivery during dry periods if buying by weight.
Summary: Plan Your Hauling and Orders Safely
Remember the fundamental benchmark: 1 cubic yard = 2,800 lbs = 1.40 US short tons. Always verify your vehicle payload limits before visiting the quarry, and factor in moisture when calculating weight-based quotes.
