That’s where our Gravel Calculator comes in—a fast, reliable, and easy-to-use tool designed to give you precise results in seconds.
What Is the Gravel Calculator Tool?
The Gravel Calculator is a user-friendly online tool that calculates the area, volume, and weight of gravel required for any project. Simply enter the length and width in feet and the depth in inches, and the tool instantly provides:
- Total area in square feet
- Volume in cubic yards
- Estimated gravel needed in tons
This tool is perfect for homeowners, landscapers, contractors, and DIY enthusiasts who want a quick and accurate estimate without manual math.
How to Use the Gravel Calculator: Step-by-Step
Using this tool is as simple as 1-2-3:
1. Input the Length
- In the first field, enter the length of the area you plan to cover, measured in feet.
2. Input the Width
- In the next field, enter the width of the area, also in feet.
3. Input the Depth
- Input the desired gravel depth in inches. This is often 2–4 inches for walkways or patios and up to 6 inches or more for driveways.
4. Click “Calculate”
- Hit the “Calculate” button to get your results.
5. View the Results
- Instantly, the tool displays:
- Area in square feet
- Volume in cubic yards
- Estimated gravel weight in tons
You can then use this information to purchase the correct amount of gravel from your local supplier.
Example: Calculating Gravel for a Driveway
Let’s say you’re laying gravel for a 20-foot by 12-foot driveway with a 4-inch depth:
- Length: 20 ft
- Width: 12 ft
- Depth: 4 inches
Step-by-Step Calculation:
- Area = 20 × 12 = 240 sq ft
- Depth in feet = 4 ÷ 12 = 0.33 ft
- Volume = 240 × 0.33 = 79.2 cubic feet
- Volume in yards = 79.2 ÷ 27 = 2.93 cubic yards
- Tons needed = 2.93 × 1.4 = ~4.10 tons
Result: You’ll need approximately 4.10 tons of gravel to complete the project.

FAQs: Everything You Need to Know About Using the Gravel Calculator
1. What does the gravel calculator measure?
It calculates the area in square feet, volume in cubic yards, and gravel weight in tons.
2. How accurate is the tool?
It uses standard conversion formulas based on average gravel density (1.4 tons per cubic yard) and is accurate for most general use.
3. What if I need gravel for multiple areas?
Use the calculator for each area separately, then add the totals to get a final amount.
4. How do I convert inches to feet for depth?
The tool automatically converts inches to feet in the background—no need for manual conversion.
5. What is the gravel weight conversion used?
The calculator assumes gravel weighs 1.4 tons per cubic yard, which is standard for crushed stone or road base.
6. Can I use this for other materials like mulch or sand?
While the math is similar, the weight per yard varies. This calculator is specifically optimized for gravel.
7. What if I enter invalid numbers?
If you input a non-numeric or negative value, the tool will prompt you to correct the input.
8. Is it okay to round up the gravel tonnage?
Yes. It’s always safer to round up slightly to account for settling or spillage.
9. Do I need to factor in compaction?
Yes, if compacting the gravel, add about 5–10% extra to your final estimate.
10. Can I use feet and inches together?
The tool accepts length and width in feet only and depth in inches, simplifying input for typical U.S. measurements.
11. How deep should gravel be for driveways?
Typically, 4–6 inches deep is recommended for most gravel driveways.
12. How much area does 1 ton of gravel cover?
Roughly 80–100 sq ft at 2 inches deep. This varies with gravel type and size.
13. Is the result in U.S. tons or metric?
The tool calculates in U.S. tons (short tons). 1 U.S. ton = 2,000 lbs.
14. Does gravel settle over time?
Yes, especially under load. Add 5–10% extra to compensate.
15. How do I reset the calculator?
Click the “Reset” button to clear all inputs and results.
16. What devices can I use this on?
The calculator works on any internet-enabled device, including phones, tablets, and desktops.
17. Does it account for different gravel types?
No, but the estimate is accurate for common types like crushed stone, pea gravel, or road base.
18. Can I embed this on my site?
If you’re the site owner or developer, yes. Otherwise, contact the site admin for permissions.
19. Do I need an internet connection?
Yes, the tool runs on your browser, so an active connection is required.
20. Where can I buy the gravel?
Use the tool to estimate your needs, then order from local landscaping or construction material suppliers.
