How much is a yard of sand weigh? A standard cubic yard of dry sand typically weighs between 2,400 and 3,000 pounds. That’s about 1.2 to 1.5 tons. The exact weight can change a lot based on things like how much water is in the sand, the kind of sand it is, and how packed down it is.

Defining a Yard of Sand
When people talk about buying sand by the yard, they mean a cubic yard. This is a measure of volume, not weight.
What is a Cubic Yard?
Think of a box. If that box is 3 feet wide, 3 feet long, and 3 feet tall, its size is a cubic yard. That box holds 27 cubic feet (3 x 3 x 3 = 27).
Sand is often sold this way for big projects like building, landscaping, or filling areas. Sellers load this amount of sand into a truck or container.
Grasping Why Sand Weight Changes
Sand weight is not just one number. Many things make the weight of a cubic yard of sand different from one load to the next.
The Idea of Density
Density is a key idea here. Sand density per cubic yard tells you how much mass (weight) is packed into that cubic yard of space. Different things change this packing and the weight.
Main Factors Affecting Sand Weight
- Moisture: Wet sand is much heavier than dry sand. Water adds weight.
- Type of Sand: Sand comes from different places and is made of different stuff. This changes how heavy the tiny grains are.
- How Packed Down It Is: Sand can be loose or squeezed together. Tightly packed sand is heavier for the same space.
- Grain Size and Shape: Big, rough grains pack differently than small, round grains.
Typical Weights for Dry Sand
When people ask about sand weight, they often mean dry sand. This is a good starting point.
Cubic Yard Sand Weight – Dry
The common range for dry sand is 2,400 to 2,800 pounds per cubic yard. Sometimes it can be a bit higher, up to 3,000 pounds, if it’s very clean and dense.
Pounds Per Cubic Yard Sand – Dry
Using pounds makes the number bigger but is often easier to work with for smaller amounts. So, dry sand is typically 2,400 to 3,000 pounds per cubic yard.
Tons Per Cubic Yard Sand – Dry
For bigger projects, people might think in tons. Since 1 ton is 2,000 pounds:
* 2,400 pounds is 1.2 tons (2400 / 2000).
* 3,000 pounds is 1.5 tons (3000 / 2000).
So, how much does a cubic yard of sand weigh in tons when dry? About 1.2 to 1.5 tons.
Bulk Sand Weight
When you buy sand from a supplier, it’s called bulk sand. This is usually measured and sold by the cubic yard or by the ton. When sold by the yard, they often estimate based on typical dry weights.
Deciphering the Weight of Wet Sand
Water makes sand much heavier. This is a big deal because sand from a pile outside will almost always have some moisture. Rain, humidity, or washing the sand add water.
Why Wet Sand is Heavier
Sand grains don’t soak up much water themselves. But water fills the tiny spaces between the grains. Water is heavy. One gallon of water weighs about 8.34 pounds. There’s a lot of space in a cubic yard of loose sand that can fill with water.
How Much Heavier is Wet Sand?
The weight of wet sand can be 20% to 30% more than dry sand. Even a little moisture adds weight. Fully saturated sand (where all the spaces are full of water) can weigh up to 3,300 pounds or more per cubic yard.
Impact of Moisture on Sand Weight
Imagine you need 2,500 pounds of sand for a project. If the supplier measures by the yard and the sand is wet, a cubic yard might weigh 3,000 pounds instead of 2,500 pounds. You might get less sand than you expected for your project, measured by its dry weight need. Or, if you buy by weight, you’ll pay for the water.
It’s important to know if the sand is wet or dry when buying. Suppliers usually give an average weight, often based on typical moisture levels for their area.
Weight of Different Types of Sand
Not all sand is the same. The rock and mineral bits that make up the sand grains change the weight.
Common Sand Types and Their Weights
Here are some common types of sand and their average dry weights per cubic yard:
| Sand Type | Description | Average Dry Weight (lbs/cubic yard) | Average Dry Weight (tons/cubic yard) |
|---|---|---|---|
| Concrete Sand | Coarse, often used in concrete and drainage. | 2,600 – 2,800 | 1.3 – 1.4 |
| Masonry Sand | Fine, used in mortar for brick and block. | 2,700 – 2,900 | 1.35 – 1.45 |
| Play Sand | Very fine, washed, often used for sandboxes. | 2,500 – 2,700 | 1.25 – 1.35 |
| Washed Sand | Sand cleaned to remove fine particles and clay. | 2,600 – 2,800 | 1.3 – 1.4 |
| Fill Sand | Less refined, used for filling large areas. | 2,400 – 2,600 | 1.2 – 1.3 |
| Beach Sand | Varies greatly, often contains shells, fine to coarse. | 2,500 – 2,800 | 1.25 – 1.4 |
| Manufactured Sand | Crushed rock, angular shape. | 2,800 – 3,000+ | 1.4 – 1.5+ |
These are average weights. Actual weights can differ based on moisture and how pure the sand is.
Calculating Sand Weight Volume
Knowing the weight per cubic yard lets you figure out the total weight for a certain amount of sand, or the amount of sand you get for a certain weight. This is sand volume to weight conversion.
Simple Calculation Method
Here’s how to calculate sand weight volume:
- Find the Volume: Figure out how many cubic yards of sand you have or need. If you have measurements in feet, divide the total cubic feet by 27 to get cubic yards.
- Example: An area is 9 feet long, 9 feet wide, and 1 foot deep.
- Cubic feet = 9 ft * 9 ft * 1 ft = 81 cubic feet.
- Cubic yards = 81 cubic feet / 27 cubic feet/yard = 3 cubic yards.
- Estimate the Weight Per Yard: Use an average weight for the type of sand you have. Let’s use 2,700 pounds per cubic yard for dry sand.
- Multiply: Multiply the number of cubic yards by the estimated weight per yard.
- Total weight = Number of cubic yards * Weight per cubic yard.
- Example: 3 cubic yards * 2,700 pounds/cubic yard = 8,100 pounds.
So, 3 cubic yards of this dry sand would weigh about 8,100 pounds.
Converting Pounds to Tons
To find the weight in tons, divide the total weight in pounds by 2,000 (since 1 ton = 2,000 pounds).
* Example: 8,100 pounds / 2,000 pounds/ton = 4.05 tons.
The total weight of 3 cubic yards of this dry sand is about 4.05 tons.
Considerations for Calculations
- Moisture: Remember to adjust your estimate if the sand is wet. Add 20-30% to the dry weight for a rough guess.
- Compaction: Sand in a truck might be looser than sand that has been sitting for a long time or compacted during a project. Loose sand weighs less per cubic yard than compacted sand.
- Supplier Data: The best way is to ask your supplier for their average weight per cubic yard for the specific sand you are buying. They deal with this all the time.
Interpreting Sand Density Per Cubic Yard
Sand density per cubic yard is simply the weight of that cubic yard. When we say sand has a density of 2,700 pounds per cubic yard, we mean one cubic yard of that sand weighs 2,700 pounds.
Why Density Matters
Density is key for:
* Buying: Knowing the density helps you figure out if buying by weight or by volume is better, or how much you’re truly getting.
* Transporting: You need to know the weight to make sure your truck or trailer can safely carry the load.
* Project Planning: Calculations for concrete mixes, fill amounts, or base layers depend on knowing the sand’s weight and volume relationship.
How Sand Density Changes
The density is higher if the sand grains themselves are heavy (like minerals such as quartz, feldspar, or heavier minerals), or if the sand is tightly packed, or if it contains water. The density is lower if the grains are lighter, the sand is loose, or it’s completely dry.
How Much Does a Cubic Yard of Sand Weigh in Tons? Revisited
Let’s nail this down. A cubic yard of dry sand usually weighs between 1.2 and 1.5 tons. A cubic yard of wet sand can weigh more, potentially up to 1.65 tons or more.
Converting Cubic Yards to Tons
To convert cubic yards to tons, you need the sand’s density (weight per cubic yard).
* Formula: Number of Tons = (Number of Cubic Yards * Weight per Cubic Yard in Pounds) / 2000
Example: You have 5 cubic yards of concrete sand that the supplier says weighs 2,700 pounds per cubic yard.
* Total pounds = 5 cubic yards * 2,700 pounds/cubic yard = 13,500 pounds
* Total tons = 13,500 pounds / 2,000 pounds/ton = 6.75 tons.
So, 5 cubic yards of this sand would be about 6.75 tons.
Sand Volume to Weight Conversion in Practice
This conversion is useful when:
* You need a certain weight of sand for a mix (like concrete or mortar) but the supplier sells by volume.
* You need to fill a space (volume) but need to know the total weight for delivery or structural reasons.
Using Conversion Factors
You can use average conversion factors.
* 1 cubic yard dry sand ≈ 1.35 tons (using 2700 lbs/yd³ average)
* 1 cubic yard wet sand ≈ 1.5 tons (using 3000 lbs/yd³ average)
These are estimates. Always ask your supplier for their specific sand’s average weight if accuracy is critical.
Fathoming Bulk Sand Weight
Bulk sand is sand sold in large amounts, not bags. It’s what you get delivered by a dump truck.
Buying Bulk Sand
Suppliers sell bulk sand by the cubic yard or by the ton.
- Buying by the Yard: You pay for a specific volume (a 3ft x 3ft x 3ft box’s worth). The weight will vary depending on moisture and type.
- Buying by the Ton: You pay for a specific weight (2,000 pounds). The volume you receive will vary depending on moisture and type.
If sand is wet, buying by the ton means you get less sand volume for the same weight because you’re paying for the water too. If sand is very dry and light, buying by the ton might give you more volume.
Why Knowing Bulk Weight Matters
It helps you compare prices. A yard of sand might cost less from one place, but if their sand is heavy/wet, you might get less useful material (dry sand) than a slightly more expensive yard from another place with lighter/drier sand.
It also ensures you order the right amount. If your project needs a certain volume, you need to know how many yards to order. If it needs a certain weight for a mix, you need to know how many tons.
Planning for Transport: Weight Is Key
Moving sand requires knowing its weight.
Truck Capacity
Every truck, trailer, and vehicle has a weight limit. This is called its Gross Vehicle Weight Rating (GVWR) or payload capacity. Exceeding this is dangerous and illegal.
If a cubic yard of sand can weigh up to 3,300 pounds (1.65 tons) when wet, even a small pickup truck might only be able to carry 1/3 or 1/2 of a cubic yard safely. A larger dump truck can carry many cubic yards, but its capacity is also limited by weight, not just the size of its bed.
Estimating Your Load
Use the average weights to estimate how much your load will weigh.
* Need 2 cubic yards of concrete sand? Estimate dry weight: 2 yards * 2700 lbs/yard = 5400 lbs (2.7 tons).
* Consider if it’s wet! Add maybe 20%: 5400 lbs * 1.20 = 6480 lbs (3.24 tons).
* Check your truck/trailer’s weight limit. Can it handle 6500+ pounds?
Always be cautious and assume the sand might be heavier than you expect, especially if it looks damp.
Summing Up Sand Weight
A cubic yard of sand weighs between 2,400 and 3,000 pounds when dry. That’s 1.2 to 1.5 tons. This is a key number to remember.
But moisture, sand type, and how packed it is change this number. Wet sand is much heavier. Different types of sand have slightly different weights.
Knowing the weight helps you order the right amount, compare costs, and safely move the sand. Always ask your supplier for the most accurate weight for the sand you plan to buy. Use our guide to make good estimates and plan your project well.

The weight per cubic yard (its density) for dry sand is typically 2,400 to 3,000 pounds. This depends on the type and moisture.
h5 Is sand sold by the ton or yard?
Sand is commonly sold by both the cubic yard (volume) and the ton (weight) in bulk. Bagged sand is sold by weight (e.g., 50 lb bag).
h5 How many pounds are in a cubic yard of sand?
There are usually 2,400 to 3,000 pounds of dry sand in one cubic yard.
h5 How many tons are in a cubic yard of sand?
There are usually 1.2 to 1.5 tons of dry sand in one cubic yard. (1 ton = 2,000 pounds).
h5 Does wet sand weigh more than dry sand?
Yes, absolutely. Water fills the spaces between sand grains and adds significant weight. Wet sand can be 20-30% heavier than dry sand.
h5 How do I calculate sand weight from volume?
- Find the volume in cubic yards.
- Get the estimated weight per cubic yard for your type of sand (ask supplier or use averages).
- Multiply cubic yards by the weight per cubic yard. (Example: 2 cubic yards * 2700 lbs/yd³ = 5400 pounds).
h5 How do different types of sand weigh differently?
Yes, they do. Sands made of heavier minerals or with different grain sizes and shapes will pack differently and have slightly different densities. For example, concrete sand and masonry sand can have slightly different average weights per cubic yard.
h5 What is bulk sand weight?
Bulk sand weight refers to the weight of sand sold in large quantities, typically measured by the cubic yard or ton, rather than in small bags. Its weight per volume varies like any other sand.
h5 Why is knowing sand weight important for delivery?
Knowing the weight is crucial for transport. Trucks and trailers have weight limits (payload capacity). You must not exceed these limits for safety and legal reasons. Knowing the sand’s weight helps you order the right amount that your vehicle or the delivery truck can carry safely.
h5 Can I estimate the weight of sand by looking at it?
It’s hard to be accurate just by looking. You can guess if it’s wet (it will look darker and clumpier), which tells you it will be heavier than dry sand. But the exact type and compaction are hard to tell visually. Always use estimated weights or ask the supplier.
