Gravel Yard Calculator
Planning a landscaping or construction project often involves calculating how much gravel you’ll need. Whether you’re filling a driveway, building a garden path, or laying a foundation, accuracy is key. Our Gravel Yard Calculator takes the guesswork out of estimating gravel volume and weight, helping you save time, money, and resources.
This easy-to-use tool converts your input dimensions (in feet or meters, inches or feet for depth) into cubic yards, cubic feet, and provides an estimated weight in tons, based on a standard average density of 1.4 tons per cubic yard. Let’s walk through how this calculator works, how to use it effectively, and answer common questions to help you make the most of it.
How to Use the Gravel Yard Calculator: Step-by-Step Guide
Using the Gravel Yard Calculator is simple. Here’s how to get accurate results:
1. Enter the Length
- Input the length of the area to be covered.
- Choose your preferred unit: feet or meters.
2. Enter the Width
- Input the width of the area.
- Again, select either feet or meters for the unit.
3. Enter the Depth
- Type the depth of gravel you need.
- Choose between inches, feet, or meters depending on your project requirements.
4. Click “Calculate”
- The tool will instantly compute:
- Cubic Yards
- Cubic Feet
- Estimated Tons of gravel needed (using the industry standard of 1.4 tons per cubic yard).
5. View the Results
- Your results appear just below the calculator with easy-to-read numbers.
- Click “Reset” to clear your inputs and start a new calculation.
Practical Example: Gravel for a Driveway
Let’s say you’re planning to build a gravel driveway that’s:
- 40 feet long
- 10 feet wide
- 4 inches deep
Here’s how you’d use the calculator:
- Length = 40, Unit = Feet
- Width = 10, Unit = Feet
- Depth = 4, Unit = Inches
- Click “Calculate”
Output:
- Cubic Yards: 4.94
- Cubic Feet: 133.33
- Estimated Weight: 6.91 tons
So you would need roughly 5 cubic yards of gravel or about 7 tons to complete the job.

FAQs: Gravel Yard Calculator
1. How many cubic feet are in a cubic yard?
There are 27 cubic feet in one cubic yard.
2. What is the weight of one cubic yard of gravel?
On average, 1 cubic yard of gravel weighs around 1.4 tons (2,800 lbs) depending on moisture and type.
3. Can I change units mid-calculation?
Yes, the calculator lets you choose between feet or meters for length and width, and inches, feet, or meters for depth.
4. What if I use meters instead of feet?
The calculator automatically converts meters to feet internally to ensure accuracy, so your results are always reliable.
5. Is this calculator suitable for sand or mulch?
While designed for gravel, it can give a rough volume estimate for other materials. However, weight estimations may not be accurate for lighter or denser substances.
6. How accurate is the tonnage estimate?
The tool uses the industry standard of 1.4 tons per cubic yard, which is a general average. For precision, consult your supplier’s material specs.
7. Can I use this for circular areas?
No, this tool is built for rectangular or square areas. For circular or irregular shapes, divide the area into smaller rectangles and calculate separately.
8. Does it factor in compaction?
No. The calculator gives loose fill volume. If compaction is necessary, multiply the total volume by an appropriate factor (e.g., 1.1–1.2).
9. How deep should gravel be for a driveway?
Typically, driveways require 4 to 6 inches of gravel. For high-traffic areas, go up to 8 inches or add multiple layers.
10. Can I use the calculator for concrete base prep?
Yes, this tool is great for calculating the gravel base layer volume under concrete slabs.
11. Why are results shown in both cubic feet and yards?
Some suppliers sell by cubic feet, while others sell by cubic yards. We provide both for flexibility.
12. Is there a mobile-friendly version?
Yes, the calculator is fully responsive and works great on both desktop and mobile browsers.
13. What types of gravel does this apply to?
This estimate works for pea gravel, crushed stone, and general landscaping gravel, but weight may vary slightly.
14. Do I need to account for wastage?
Yes, it’s good practice to add 5–10% extra to your total to account for compaction, spreading errors, and wastage.
15. Can I export or print the results?
While not built-in, you can screenshot or copy the results into a spreadsheet or print them from your browser.
16. How do I reset the form?
Click the “Reset” button, and all fields will clear automatically.
17. Is this calculator free to use?
Yes, it’s completely free and requires no login or subscription.
18. Will this work for raised garden beds?
Absolutely. It’s ideal for calculating how much gravel you need at the base of planter boxes or raised beds.
19. Is the result instant?
Yes. Once you enter your dimensions and hit “Calculate,” results are displayed immediately.
20. Can I trust the results for large commercial projects?
For small to medium jobs, yes. For large-scale commercial projects, we recommend using this as a preliminary tool and confirming with a site engineer or materials supplier.
