How much does a yard of gravel weigh? A cubic yard typically weighs between 2,400 and 3,000 pounds (about 1.2 to 1.5 tons). For planning purposes, 2,800 pounds (1.4 tons) is a useful estimate, but the actual weight can vary by material and moisture.
The exact weight of your gravel will vary based on three main factors: the type of gravel, how much moisture it contains, and how compacted it becomes. This guide explains what affects gravel weight, gives you specific numbers for pea gravel and 3/4″ crushed stone, and shows you exactly how to calculate what you need for your project.
How Much Does a Yard of Gravel Weigh? The Quick Answer
So, how much does a yard of gravel weigh? A cubic yard weighs 2,400 to 3,000 pounds. For planning purposes, 2,800 pounds (1.4 tons) is a useful estimate.
Because a cubic yard contains 27 cubic feet, bulk densities around 90–110 pounds per cubic foot correspond to roughly 2,400–3,000 pounds per cubic yard. The 2,800-pound figure is a practical planning estimate within this typical range—but always verify the weight of your specific material with your supplier before ordering by the ton or loading a vehicle.
How Much Does a Yard of Pea Gravel Weigh?
If you’re asking how much does a yard of gravel weigh when using pea gravel, the answer is around 2,800 pounds. Pea gravel is a popular choice for walkways, patios, playgrounds, and drainage areas. Its smooth, rounded stones are naturally tumbled by water, which creates more air pockets (voids) between pieces compared to crushed rock.
| Measurement | Weight |
|---|---|
| Average weight per cubic yard | ~2,800 lbs (1.4 tons) |
| Typical planning range | 2,400–3,000 lbs |
| Compacted (settled) | Can reach 2,900–3,000 lbs |
Why the variation? Pea gravel’s rounded shape traps more air when poured loosely. When gravel settles or is compacted, the particles rearrange and reduce the amount of empty space between them. This increases the bulk density, meaning more gravel mass occupies the same measured volume.
How Much Does a Yard of 3/4″ Gravel Weigh?
If you’re wondering how much does a yard of gravel weigh for 3/4″ crushed stone, the answer is also around 2,800 pounds on average. 3/4″ gravel, also sold as 3/4″ crushed stone or 3/4″ minus, is a workhorse material for driveways, road bases, and drainage projects. It’s mechanically crushed, producing angular pieces that interlock with each other. It also often contains “fines” (smaller particles and dust) that fill gaps between larger stones.
| Measurement | Weight |
|---|---|
| Average weight per cubic yard | ~2,800 lbs (1.4 tons) |
| Typical planning range | 2,400–3,000 lbs |
| Well-compacted | Often at the higher end of the range |
Why the variation? Angular crushed stone packs more tightly than rounded pea gravel. The interlocking edges and fine particles reduce air gaps, so a compacted yard of 3/4″ gravel can weigh closer to 3,000 lbs than 2,400 lbs.
What Factors Affect the Weight of a Yard of Gravel?
Why does the weight vary so much? Three physical factors do most of the work.
1. Moisture Content
Stone is porous. Gravel left in the rain absorbs water and becomes heavier.
How much heavier? It varies significantly based on:
- The rock type (some stones are more porous than others)
- How long the material has been exposed to water
- The size of the gravel particles
A load of wet gravel can weigh noticeably more than the same volume of dry gravel. That’s why knowing how much does a yard of gravel weigh when wet versus dry is important for accurate ordering. If you’re ordering by weight (by the ton) rather than by volume, ask your supplier whether their stock is wet or dry. If material is sold by weight, moisture can affect the amount of water included in the measured load.
Practical tip: If you’re weighing your load on a truck scale, the reading may include water weight that won’t help your project. Ask your supplier for the weight of their material when dry to get a more accurate comparison.
2. Material Composition (Rock Type)
Not all rock is equally dense. The parent rock from which the gravel is crushed is one factor in its overall density.
| Rock / Material | General Tendency |
|---|---|
| Granite, limestone, quartz-based gravel | Often denser |
| Sandstone or shale-based gravel | Can be less dense |
A cubic yard of granite-based gravel will often weigh more than the same volume of sandstone-based gravel, even when both are dry and loose. However, bulk density also depends on particle size, grading, void ratio, moisture, and compaction—all of which are covered elsewhere in this guide.
3. Compaction and Air Gaps
This is about the void space inside a cubic yard.
- Loose gravel has more air gaps between stones, so fewer actual pounds fit into a cubic yard
- Settled or compacted gravel closes those gaps, so more material fits into the same volume
- Rounded stones (like pea gravel) create larger air gaps than angular crushed stone, which nests more tightly
This is why a cubic yard of compacted 3/4″ crushed stone can weigh more than a cubic yard of loose pea gravel, even though their averages are similar.
Recommended Gravel Depth for Your Project
Before you can calculate how much does a yard of gravel weigh for your project, you need to know how deep to lay the gravel. Depth varies by application.
| Project | Typical Planning Range |
|---|---|
| Decorative ground cover / mulch alternative | 1–2 inches |
| Walkways and pathways | 2–3 inches |
| Patios (under pavers) | 2–4 inches |
| Driveway top layer | 4–6 inches |
| Driveway full base + top | 6–8 inches (often built in layers) |
| Drainage base / French drains | 6–12 inches |
Important: These are planning ranges, not construction specifications. For driveways and structural applications, the correct depth depends on soil type, drainage, traffic load, climate, and your specific project design. Always verify requirements with a qualified professional or local building standards.
How to Calculate Gravel Weight for Your Project
To determine how much does a yard of gravel weigh for your specific project, follow these steps.
Step 1: Find the Volume
Measure the length, width, and desired depth of your project area, then convert to cubic yards.
Cubic feet: Length (ft) × Width (ft) × Depth (ft) = Total Cubic Feet
Remember to convert inches to feet—e.g., 3 inches = 3 ÷ 12 = 0.25 feet
Cubic yards: Divide total cubic feet by 27 (there are 27 cubic feet in a cubic yard)
Formula: (Length × Width × Depth) / 27 = Cubic Yards
Example: A 10-foot by 10-foot patio with a 3-inch (0.25-foot) layer of pea gravel.
- Cubic feet: 10 × 10 × 0.25 = 25 cubic feet
- Cubic yards: 25 ÷ 27 ≈ 0.93 cubic yards
Step 2: Add a Compaction/Waste Buffer
Gravel settles after delivery, and real-world areas rarely measure out perfectly. Many people add an allowance for settling, spillage, and measurement differences, but the appropriate amount depends on the project and material.
Example (continued): 0.93 cubic yards × 1.10 ≈ 1.02 cubic yards
Depending on the supplier’s ordering increments, you might order 1 to 1.1 cubic yards for this project.
Step 3: Estimate the Weight
Multiply your final volume by the estimated weight per cubic yard for your gravel type. Now you know exactly how much does a yard of gravel weigh for your project.
Formula: Cubic Yards × Weight per Cubic Yard = Total Weight
Example (continued): Using the planning estimate of 2,800 lbs per yard: 1 × 2,800 = 2,800 pounds (1.4 tons)
Step 4: Convert Weight Back to Volume (If You Already Have the Weight)
If you have a load of gravel and know its weight—for example, from a dump truck scale ticket—you can calculate how many cubic yards you received.
Formula: Total Weight ÷ Weight per Cubic Yard = Cubic Yards
Example: You receive a load weighing 5,600 lbs. 5,600 ÷ 2,800 = 2 cubic yards.
This is useful for verifying that you received the amount you ordered.
Step 5: Let the Calculator Do the Work
Manual calculation works, but it leaves room for rounding errors, especially across multiple areas or irregular shapes. TheCalcYard.com Gravel Calculator does this automatically—enter your project dimensions and select your gravel type, and it calculates volume and estimated weight for you, including a compaction buffer.
Quick Reference: Weight Conversions
| Volume | Approx. Weight |
|---|---|
| 1 cubic foot | ~100–105 lbs |
| 1/2 cubic yard | ~1,400 lbs |
| 1 cubic yard | ~2,800 lbs (1.4 tons) |
| 2 cubic yards | ~5,600 lbs (2.8 tons) |
| 5 cubic yards | ~14,000 lbs (7 tons) |
These figures use the 2,800-lb planning estimate, equivalent to about 104 pounds per cubic foot. Lighter materials (sandstone-based) or very dense ones (quartz or granite-based) will shift these numbers by a few hundred pounds per yard in either direction.
Practical Considerations: Ordering and Hauling Gravel
Knowing how much does a yard of gravel weigh isn’t just an academic exercise. It affects how you buy the material and how you get it home.
Buying by Volume vs. by Weight
Suppliers typically sell gravel either by the cubic yard (volume) or by the ton (weight).
| Method | Best For |
|---|---|
| Ordering by volume (cubic yards) | DIY projects where you measure your space and order a specific volume |
| Ordering by weight (tons) | Large commercial jobs where material density can vary; more precise for bulk pricing |
If your supplier prices by the ton, use the conversion table above to translate your project’s volume into an expected weight. This lets you compare a per-ton quote against a per-yard price.
Also consider: Heavier, denser gravel may cost more to ship by weight. If you have a choice between lighter and heavier material for a non-structural project, factor in delivery costs too.
One more tip: If a delivered load comes in noticeably lighter than expected for its stated tonnage, ask whether the material was wet when weighed. Moisture can significantly affect the volume-to-weight ratio.
Understanding Your Hauling Limits
If you’re hauling gravel yourself rather than having it delivered, payload capacity matters—and it varies far more by vehicle than people expect.
The “half-ton” naming trap: “Half-ton,” “3/4-ton,” and “1-ton” are legacy naming conventions, not literal payload limits. Payload capacity varies widely among modern half-ton pickups, depending on the make, model, configuration, and trim.
Why this matters: A single cubic yard of gravel can weigh close to 2,800 pounds. A full yard may exceed what some half-ton trucks can safely carry, while others can handle it with room to spare.
Before loading up:
- Check your specific truck’s payload rating on the door-jamb sticker or in the owner’s manual. Do not assume based on the “half-ton” label.
- Remember payload includes passengers and any other cargo in or on the vehicle, not just what’s in the bed.
- Leave a safety margin rather than loading to the exact rated limit. Wet gravel or measurement error can push you over.
- If you’re unsure or your project needs more than one yard, splitting the load into smaller trips, or having the supplier deliver—is the safer option.
Frequently Asked Questions
How much does a yard of gravel weigh exactly?
A cubic yard of gravel typically weighs about 1.4 tons on average, though it can range from roughly 1.2 to 1.5 tons depending on the gravel type and moisture content.
How much does 1 cubic foot of gravel weigh?
Around 100 to 105 pounds for an average gravel mix. At the 2,800-lb planning estimate, one cubic foot weighs about 104 pounds: 2,800 ÷ 27 ≈ 103.7 lbs.
Which is heavier, pea gravel or 3/4″ gravel?
Their averages are close (both around 2,800 lbs per yard). However, 3/4″ crushed stone can edge out pea gravel at the higher end of the range once compacted, because its angular shape and fine particles pack more tightly and leave less air space.
Can I use a gravel calculator for my fish tank?
Yes, the same volume-times-density approach works. However, aquarium gravel can have a very different density depending on whether it is made from quartz, natural stone, ceramic, glass, or another material. Check the product’s listed weight or density when calculating the amount needed.
Where does the 2,800-pound average come from?
The 2,800-pound figure is a practical planning estimate within the typical range for common gravel. Bulk densities around 90–110 pounds per cubic foot correspond to roughly 2,400–3,000 pounds per cubic yard. Because actual density varies by material, grading, moisture, and compaction, the exact weight should be confirmed with your supplier.
Conclusion
So, how much does a yard of gravel weigh? The honest answer is a range: roughly 2,400 to 3,000 pounds, with 2,800 pounds (1.4 tons) as a commonly used planning estimate. Where you land in that range depends on the type of gravel, how wet it is, and how compacted it becomes after delivery.
For most projects, that’s enough to get a solid ballpark. But if you want an exact figure for your specific dimensions and gravel type—including a built-in buffer for compaction, TheCalcYard.com Gravel Calculator does the calculation for you in seconds. Enter your measurements, select your material, and get volume, weight, and practical ordering recommendations.
