3/4 Gravel Calculator
Whether you’re building a driveway, laying a patio base, or planning a landscaping project, estimating how much gravel you need can be a challenge. Buying too much gravel means wasted money; buying too little causes delays. That’s why we created this 3/4″ Gravel Calculator — a free, easy-to-use tool that quickly gives you the volume and weight of gravel required for your project, based on your specific dimensions and unit preferences.
In this guide, we’ll walk you through how the tool works, how to use it step-by-step, and why it’s essential for your planning process. Plus, we’ve included practical examples, use cases, and a robust FAQ section to help you make the most of your project.
🔧 What Does the 3/4″ Gravel Calculator Do?
The gravel calculator is designed to estimate two main things:
- Volume in Cubic Yards – This is the amount of space your gravel will occupy.
- Weight in Tons – This gives you an approximate weight based on standard 3/4″ crushed stone (approx. 1.4 tons per cubic yard).
Using your inputted dimensions—length, width, and depth—the calculator converts your measurements into feet (if needed), computes the total volume in cubic feet, then converts that to cubic yards and finally into tons.
📝 How to Use the Gravel Calculator (Step-by-Step)
Using the tool is simple and only takes a minute. Follow these steps:
Step 1: Input the Length
Enter the length of your project area. You can select whether your measurement is in feet or meters.
Step 2: Input the Width
Next, enter the width and choose your desired unit (feet or meters).
Step 3: Input the Depth
Enter how deep you want the gravel layer to be. For depth, you can choose inches or feet as your unit.
Step 4: Click “Calculate”
Hit the Calculate button. The tool will instantly show:
- The volume in cubic yards
- The estimated weight in tons
Step 5: Review or Reset
If you want to start over, click the Reset button to clear the inputs and try again.
💡 Example: Planning a Driveway
Let’s say you’re building a 20-foot-long by 10-foot-wide driveway with 4 inches of gravel.
- Length: 20 feet
- Width: 10 feet
- Depth: 4 inches
Calculation:
- 4 inches = 0.333 feet
- Volume = 20 × 10 × 0.333 = 66.6 cubic feet
- Cubic Yards = 66.6 ÷ 27 = 2.47 cubic yards
- Tons = 2.47 × 1.4 = 3.46 tons
So, you’ll need approximately 3.46 tons of 3/4″ gravel for your driveway.
🌍 Why Accurate Gravel Estimation Matters
🛠️ Cost Efficiency
Overestimating means spending more than necessary. Underestimating may cause project delays.
♻️ Environmental Impact
Only ordering what you need helps reduce waste and environmental impact.
📦 Delivery Logistics
Gravel is heavy. Knowing the exact tonnage helps with scheduling proper transport and delivery equipment.
✅ Common Use Cases
- Driveways and private roads
- Walkways and garden paths
- Patio bases or shed foundations
- Landscaping and drainage solutions
- French drains and retaining walls
- Utility trench backfilling
❓ Frequently Asked Questions (FAQs)
1. What is 3/4″ gravel used for?
It’s commonly used for driveways, drainage projects, patios, and as a base layer for construction projects due to its good compaction and drainage properties.
2. How many cubic feet are in a cubic yard?
There are 27 cubic feet in one cubic yard.
3. How much does 1 cubic yard of 3/4″ gravel weigh?
On average, about 1.4 tons (2,800 pounds).
4. Can I enter metric units?
Yes! The tool accepts both feet/meters for length and width, and inches/feet for depth.
5. Is this calculator accurate?
Yes, it provides reliable estimates based on standard gravel density and dimensional conversions.
6. What if my area is irregular in shape?
Break it into smaller rectangular sections, calculate each separately, and add the results.
7. What depth should I use for a driveway?
Typically 4 to 6 inches, depending on expected load and usage.
8. Can this tool be used for other materials?
It’s optimized for 3/4″ gravel, but you can use it for similar-density materials with caution.
9. How do I convert meters to feet?
The calculator automatically does this for you. 1 meter = 3.28084 feet.
10. Is delivery included in tonnage estimates?
No. Delivery cost depends on the supplier, not the weight alone.
11. Do I need to compact the gravel before measuring?
No, but be aware compacted gravel takes up slightly less space.
12. Can I use this tool on mobile?
Absolutely. The calculator is responsive and works on all devices.
13. What type of gravel is best for drainage?
3/4″ crushed gravel is ideal due to its size and ability to allow water flow.
14. Do I need to include extra gravel for settling?
Yes, consider ordering 5–10% extra to account for settling and spillage.
15. How many tons fit in a standard dump truck?
Most trucks carry 10–14 tons, depending on the truck and legal limits.
16. Is gravel sold by cubic yard or ton?
Both. Suppliers may offer pricing in cubic yards or by the ton, so knowing both helps.
17. Can I reuse gravel from another project?
Yes, but ensure it’s clean and uncontaminated before reuse.
18. Does moisture affect gravel weight?
Yes, wet gravel can weigh more due to water content.
19. Can I calculate gravel for a circular area?
Yes, but first calculate the area of the circle and use it as the width × length value:Area = π × radius²
20. Where can I buy 3/4″ gravel?
Local landscaping supply companies, hardware stores, or aggregate suppliers.
