Introduction
The Sand Calculator helps you figure out how much sand you need for your construction project. Whether you are filling a sandbox, laying a patio base, or preparing ground for a building, knowing the right amount of sand saves you time and money. Too little sand means extra trips to the supplier. Too much sand means wasted material and higher costs.
With this tool, you simply enter the length, width, and depth of the area you need to fill. The calculator then tells you how much sand you need in volume and weight. It takes the guesswork out of ordering materials so you can plan your project with confidence. Sand is one of the most common materials used in construction, and getting the amount right is one of the first steps to doing a job well. If you're working on a project that also involves other aggregates, you might find our Pea Gravel Calculator or River Rock Calculator helpful as well.
How to Use Our Sand Calculator
Enter the details of your project area and sand type below. This calculator will tell you how much sand you need in volume and weight.
Length: Enter the length of the area you need to fill with sand. This is how long the space is from one end to the other. You can use feet, meters, or other units. If you need help determining the area of your project space, our Square Footage Calculator can assist.
Width: Enter the width of the area. This is how wide the space is from side to side. Use the same unit you picked for length.
Depth: Enter how deep or thick you want the sand layer to be. This is often measured in inches or centimeters. A common depth for most projects is between 2 and 4 inches.
Sand Density: Pick the type of sand you are using or enter a custom density value. Different sands weigh different amounts. For example, dry sand weighs about 100 pounds per cubic foot, while wet sand weighs more. This helps the calculator figure out the total weight you need to buy.
Price Per Unit (optional): If you know the cost of sand per ton or per cubic yard in your area, enter it here. The calculator will estimate the total cost of sand for your project.
Sand Calculator
A sand calculator helps you figure out how much sand you need for your project. Whether you are filling a sandbox, laying pavers, or preparing a foundation, knowing the right amount of sand saves you time and money. Buying too little means extra trips to the store. Buying too much means wasted material and money.
How Sand Is Measured
Sand is usually measured by volume (cubic feet, cubic yards, or cubic meters) or by weight (pounds or tons). To find the volume you need, you multiply the length × width × depth of the area you want to fill. Once you know the volume, you can convert it to weight since sand has a known density.
Sand Density
The density of sand depends on how wet or dry it is and how tightly it is packed. On average, dry sand weighs about 100 pounds per cubic foot (1,600 kg per cubic meter). Wet sand is heavier, often reaching 120 pounds per cubic foot or more. Most suppliers sell sand by the ton, so converting volume to weight is an important step.
Common Types of Sand in Construction
- All-purpose sand – Used for general fill and mixing with cement. When mixing sand into concrete, our Concrete Calculator can help you determine the right proportions.
- Mason sand – A fine sand used for mortar, pavers, and sandboxes.
- Concrete sand – A coarser sand mixed into concrete for strength.
- Fill sand – Used to fill large holes or level ground before building.
Tips for Ordering Sand
Always order about 5% to 10% more sand than your calculation shows. Some material is lost during delivery and spreading. Sand also settles and compacts over time, so a little extra ensures full coverage. If you are working on a sloped area, you may need even more to account for uneven depth.
Using a sand calculator takes the guesswork out of your project and helps you order the right amount the first time. If your project also involves paving or surfacing, you may want to check out our Asphalt Calculator or Mulch Calculator for landscaping areas. For projects that require epoxy coatings over sand-leveled surfaces, our Epoxy Calculator can help you plan that step as well.
Frequently Asked Questions
How much sand do I need for a 10x10 area?
For a 10 ft × 10 ft area at 4 inches deep, you need about 1.23 cubic yards or roughly 1 ton of sand. At 6 inches deep, you need about 1.85 cubic yards or roughly 1.5 tons. Enter your exact measurements into the calculator to get a precise number.
How many bags of sand are in a cubic yard?
A cubic yard of sand equals about 27 cubic feet. Most bags of sand sold at hardware stores are 50 pounds each. Since a cubic yard of dry sand weighs about 2,700 pounds, you would need roughly 54 bags (50 lb each) to equal one cubic yard.
How do I convert cubic feet of sand to tons?
Multiply the cubic feet by the sand density in pounds per cubic foot, then divide by 2,000. For example, 50 cubic feet × 100 lb/ft³ = 5,000 lb ÷ 2,000 = 2.5 US tons. The calculator does this conversion for you automatically.
What is the difference between the Length & Width tab, Area tab, and Volume tab?
The Length & Width tab lets you enter length, width, and depth separately. The Area tab is for when you already know the square footage and just need to add depth. The Volume tab is for when you already know the total cubic feet, cubic yards, or cubic meters of sand you need.
Why does the calculator ask for sand type?
Different types of sand have different densities. For example, wet beach sand is much heavier than dry play sand. Choosing the right sand type ensures the weight and cost estimates are accurate for the specific material you plan to buy.
What sand density should I use if I don't know my sand type?
Use the Sand (Dry — General) option, which has a density of about 1,602 kg/m³ (100 lb/ft³). This is a safe average for most dry sand. If the sand will be wet or damp, choose Sand (Wet — General) at about 1,922 kg/m³ instead.
How much does a cubic yard of sand cost?
Sand typically costs between $25 and $50 per ton, depending on the type and your location. A cubic yard of sand weighs about 1.3 to 1.5 tons, so expect to pay roughly $30 to $75 per cubic yard. Enter your local price into the calculator for an exact estimate.
Why should I add extra for waste?
Sand is lost during delivery, spreading, and compaction. The ground may also be uneven, requiring more material in some spots. Adding 5% to 10% extra ensures you have enough to finish the job without a second trip to the supplier.
How do I switch between imperial and metric results?
Click the Imperial or Metric toggle button above the results cards. Imperial shows volume in cubic feet and weight in pounds. Metric shows volume in cubic meters and weight in kilograms. The detailed breakdown table always shows both units.
Can I enter a custom sand density?
Yes. Type any density value into the density field and the sand type will automatically switch to Custom. You can enter the density in kg/m³, lb/ft³, or lb/yd³ by choosing the unit from the dropdown next to the field.
How deep should sand be under pavers?
A sand bed under pavers is usually 1 inch thick. This is the leveling layer placed on top of a compacted gravel base. Enter 1 inch as your depth in the calculator along with the length and width of your paver area to find out how much sand you need.
How much does wet sand weigh compared to dry sand?
Wet sand is about 20% heavier than dry sand. Dry sand weighs roughly 100 lb per cubic foot (1,600 kg/m³), while wet sand weighs about 120 lb per cubic foot (1,920 kg/m³). Select the wet or dry option in the sand type dropdown to get the right density.
How many tons of sand fit in a dump truck?
A standard dump truck holds about 10 to 14 tons of sand, depending on the truck size. A smaller single-axle dump truck carries around 5 to 7 tons. Use the calculator to find your total weight, then divide by your truck capacity to know how many loads you need.
What is the difference between fill sand and mason sand?
Fill sand is coarse and used to fill holes, trenches, or level ground. Mason sand is finer and screened, making it ideal for mortar mixes, sandboxes, and under pavers. Mason sand has a slightly lower density (about 1,500 kg/m³) compared to fill sand (about 1,600 kg/m³).
How does the price per unit option work?
Enter the cost of sand and choose how it is sold — per US ton, per metric tonne, per pound, per kilogram, per cubic yard, per cubic foot, or per cubic meter. The calculator uses this along with the density and volume to estimate your total material cost, both with and without the waste percentage.
