- Choose either inches or centimeters.
4. Select Gravel Density
- Choose a density level based on the gravel type:
- Light (100 lb/ft³)
- Medium (105 lb/ft³) – typical for general landscaping gravel
- Heavy (110 lb/ft³) – dense, crushed stone types
5. Click “Calculate”
- The calculator will instantly show:
- Total volume in cubic feet
- Estimated weight in tons
- Volume in cubic yards
6. Optional: Reset the Form
- Click Reset to clear all values and start over.
Practical Example: Calculating Gravel for a Backyard Patio
Let’s say you’re building a 10-foot by 12-foot backyard patio and you want a 4-inch gravel base. Here’s how you’d use the calculator:
- Length: 10
- Width: 12
- Depth: 4
- Units: Length & Width in feet, Depth in inches
- Gravel Density: Medium (105 lb/ft³)
After clicking Calculate, you’ll get results like:
- Volume: 40 ft³
- Weight: ~2.1 tons
- Cubic Yards: ~1.48 yd³
You now know exactly how much gravel to purchase—saving you both time and money.
Why Use a Gravel Calculator?
Gravel is typically sold by the ton or cubic yard, and estimating manually can be confusing. Our calculator converts dimensions and weight across multiple units, making it perfect for:
- Homeowners planning small DIY landscaping projects
- Contractors needing quick estimates on-site
- Gardeners designing beds or walkways
- Builders preparing for base layers or drainage
Bonus: Gravel Density Breakdown
Different gravel types have varying densities, which can affect your total weight. Here’s a quick guide:
| Gravel Type | Density (lb/ft³) | Use Case |
|---|---|---|
| Pea Gravel | ~100 | Pathways, decoration |
| Crushed Stone | ~105 | General landscaping, driveways |
| Dense Grade Aggregate | ~110 | Foundation, road base |
Frequently Asked Questions (FAQs)
1. How accurate is the gravel calculator?
The calculator provides a very close estimate, ideal for ordering gravel. However, always order a little extra (5–10%) to account for compaction and spillage.
2. What units does the calculator support?
You can enter dimensions in feet, meters, inches, or centimeters. Results are given in ft³, yd³, and tons.
3. What is the difference between cubic feet and cubic yards?
1 cubic yard = 27 cubic feet. The calculator shows both for convenience.
4. How many tons of gravel are in a cubic yard?
It depends on density, but generally 1 cubic yard of gravel weighs between 1.2–1.5 tons.
5. What gravel density should I choose?
Choose based on gravel type. Use:
- 100 lb/ft³ for light gravel (pea gravel)
- 105 lb/ft³ for average landscaping gravel
- 110 lb/ft³ for heavy crushed stone or compact aggregate
6. Can I use this for driveway projects?
Absolutely. Just measure the area of your driveway and enter the depth of your gravel layer.
7. Should I include extra gravel in my order?
Yes. A 5–10% buffer is recommended to account for settling, compaction, or waste.
8. Does the calculator account for compaction?
No. The calculator shows raw volume. If compaction is expected, add extra material manually.
9. Can I calculate for multiple areas?
Yes, just calculate one area at a time or break your space into sections and sum the results.
10. What if my area isn’t a perfect rectangle?
Divide the area into smaller rectangles, calculate separately, then add the results together.
11. Is this calculator mobile-friendly?
Yes! It’s fully responsive and works seamlessly on phones and tablets.
12. Can I switch between metric and imperial units?
Yes. You can mix and match units (e.g., meters and inches) as needed.
13. Is gravel sold by weight or volume?
Gravel is typically sold by ton or cubic yard, depending on your supplier.
14. Do I need to compact the gravel after spreading?
For stability, yes—especially for driveways and walkways.
15. What if I use a gravel density not listed?
Use the closest density or average. For specific materials, consult the supplier for the exact value.
16. Can I use this for mulch or sand?
This tool is optimized for gravel. Mulch and sand have different densities and compaction behavior.
17. Is gravel environmentally friendly?
Yes, especially when sourced locally. It’s permeable, reducing runoff, and can be reused.
18. Does depth make a big difference in cost?
Absolutely. Doubling the depth doubles the volume—and the cost.
19. What’s the best depth for gravel pathways?
3–4 inches is typical for paths; driveways may need 4–6 inches.
20. Can I save or print the results?
While there’s no built-in save feature, you can screenshot or copy the results for reference.
