Sand And Gravel Calculator
Planning a construction or landscaping project often requires accurate estimates of materials like sand, gravel, or a mix of both. Whether you’re laying a foundation, building a patio base, or preparing a garden bed, miscalculating the amount of material can lead to delays, wasted money, or a shortage mid-project.
Our Sand and Gravel Calculator solves this problem by helping you accurately calculate the volume and estimated weight of materials needed, based on your project’s dimensions. This tool is ideal for both DIY homeowners and professional contractors.
What Does the Sand and Gravel Calculator Do?
The calculator takes three measurements — length, width, and depth — along with the type of material you’ll use (sand, gravel, or a mix), and instantly provides:
- Total Volume in cubic meters (m³)
- Estimated Weight in kilograms (kg)
- Material-specific density explanation to support transparency in the calculation
It uses standard material densities:
- Sand: 1600 kg/m³
- Gravel: 1500 kg/m³
- Sand & Gravel Mix: 1550 kg/m³
These values are common in civil and landscaping projects, offering realistic, professional-grade results.
How to Use the Sand and Gravel Calculator
Using this tool is simple and takes less than a minute:
Step-by-Step Instructions
- Enter Length (meters):
Measure the length of your project area and enter it in meters. For example, a pathway that is 4 meters long. - Enter Width (meters):
Enter the width of the area. For a 2-meter wide section, input “2”. - Enter Depth (centimeters):
Specify how deep the layer of sand or gravel needs to be. Most projects use 5–20 cm. This field accepts decimals, so “12.5” cm is fine. - Select Material Type:
Choose from three options:- Sand
- Gravel
- Sand & Gravel Mix
- Click “Calculate”:
The calculator processes your input and displays:- Total volume (in cubic meters)
- Estimated weight (in kg)
- Explanation of material and density used
- Reset if Needed:
Click “Reset” to clear all fields and calculate again with different inputs.

15+ Frequently Asked Questions (FAQs)
1. What is the difference between sand and gravel?
Sand has finer particles and is often used for smoothing surfaces or making mortar. Gravel is coarse and used for drainage and foundational support.
2. What does the calculator measure in?
Length and width are entered in meters, depth in centimeters, and the result is given in cubic meters (m³) and kilograms (kg).
3. Why does the depth use centimeters instead of meters?
Because many common applications (like laying base material) only require shallow depths of 5–20 cm.
4. How accurate are the density values?
They are average values based on industry standards. Real-world results may vary slightly depending on material moisture and compactness.
5. Can I use this for pea gravel or crushed stone?
Yes, but keep in mind their density might vary slightly. Gravel here assumes average compacted density.
6. How can I convert the result to tons?
Divide the weight in kilograms by 1000. For example, 2000 kg = 2 tons.
7. Can I use feet or inches instead of meters and centimeters?
No, this tool uses metric units. You can convert imperial to metric using:
1 foot = 0.3048 meters
1 inch = 2.54 centimeters
8. Is it suitable for wet sand or gravel?
The calculator assumes dry material. Wet materials are heavier due to water absorption.
9. What if I need to fill a circular area?
First, calculate the radius of the circle and use the formula for area:
π × radius². Then input that as the length × width (e.g., 3.14 × r² × depth).
10. Can I use this for concrete mix estimation?
No, this calculator is for raw materials (sand/gravel), not mixed concrete. Use a concrete calculator for that purpose.
11. Why is the output volume in cubic meters?
Cubic meters (m³) is the standard unit for bulk material volume in most international projects and supplier quotes.
12. Do I need to adjust for compaction?
For tightly compacted areas, you may need 5–10% extra material to account for settling.
13. What’s the best depth for a gravel driveway?
Typically 10–15 cm (4–6 inches) is sufficient, depending on traffic and soil condition.
14. Is this tool mobile-friendly?
Yes! It works smoothly on desktops, tablets, and smartphones.
15. How do I calculate material for multiple areas?
Use the calculator for each section separately, then add the results together for total volume and weight.
16. Where do I buy materials once I know how much I need?
Most hardware stores, landscaping supply centers, and quarries sell by cubic meter or ton — now you’ll know exactly what to ask for.
17. Is this calculator suitable for industrial projects?
Yes. While it’s simple enough for homeowners, professionals can use it for site planning and material estimation.
18. Can I save or print the results?
You can copy the results to a document or screenshot them for easy access later.
19. Why is material density important?
Different materials weigh differently even at the same volume. Accurate density ensures your weight estimate is reliable.
20. How can I share this calculator with my team?
Send them a link to the webpage or embed the calculator into your own project management or quoting systems.
