Gravel Calculator – Estimate Gravel Tons, Cubic Yards & Cost
🪨 Gravel Driveway & Pathway Estimator
🪨 Let me save you from a common gravel estimating mistake...
Early in my landscaping career, I ordered gravel for a 500 sq ft driveway. I thought I had it figured out. I was off by 4 tons. The delivery truck dumped a mountain of gravel, and I had to pay extra to have the excess hauled away. That mistake cost me $300.
That's when I learned: gravel estimation isn't just length × width × depth. Here's what most people get wrong:
- Different gravel types have different densities — Pea gravel: 1.4 tons/yd³, Crushed stone: 1.5 tons/yd³, River rock: 1.6 tons/yd³
- Depth matters for different uses — Pathways: 2 inches, Driveways: 3-4 inches, Drainage: 4-6 inches
- Compaction reduces volume — Gravel settles 10-15% after installation and rain
- Always add 10-15% extra — Uneven ground, spillage, and settling add up quickly
This calculator handles all of it. Enter your dimensions, get exact cubic yards, tons, and cost. No more guessing or costly mistakes.
📖 How to Use This Gravel Calculator
- Measure your area — Length and width in feet
- Enter depth — 2-3 inches for pathways, 3-4 inches for driveways
- Add cost per ton — Optional, for budget estimation
- Click calculate — Get cubic yards, tons, and total cost
💡 Pro tip: Always order 10-15% extra for settling and uneven ground. Gravel compresses over time.
📊 Gravel Coverage Guide (per ton)
| Depth | Coverage (sq ft per ton) | Best For |
|---|---|---|
| 1 inch | 240 sq ft | Decorative topping |
| 2 inches | 120 sq ft | Walkways, pathways |
| 3 inches | 80 sq ft | Driveways, light traffic |
| 4 inches | 60 sq ft | Heavy traffic driveways |
| 6 inches | 40 sq ft | Drainage, base material |

💡 5 Gravel Tips I Wish I Knew
- Add 10-15% for settling. Gravel compacts significantly after installation and rain. Order extra to avoid running short.
- Different gravel types have different weights. Pea gravel: 1.4 tons/yd³, Crushed stone: 1.5 tons/yd³, River rock: 1.6 tons/yd³.
- Order delivery on a dry day. Wet gravel is heavier (costs more per ton) and harder to spread evenly.
- Install landscape fabric first. Prevents weeds from growing through your gravel and reduces maintenance.
- Use crushed stone for driveways. It locks together better than rounded gravel. Pea gravel shifts too much under tires.
📐 How This Gravel Calculator Works
The calculator multiplies length × width × depth to find cubic feet, then converts to cubic yards (÷27) and tons (×1.4). Cost is calculated by multiplying tons by price per ton.
The Formula: Cubic Yards = (Length × Width × (Depth/12)) ÷ 27. Tons = Cubic Yards × 1.4.
