How to Calculate Gravel for Your Project

Whether you're installing a new driveway, creating a decorative walkway, or improving drainage around your property, knowing how much gravel to order is essential. Our free gravel calculator converts your measurements into cubic yards, tons, and truckloads—helping you order the right amount and avoid costly mistakes.

Understanding Gravel Measurements

Gravel can be purchased by volume (cubic yards) or weight (tons). Understanding the relationship between these measurements helps you compare prices and plan deliveries:

• 1 cubic yard = 27 cubic feet
• 1 cubic yard of gravel ≈ 1.4-1.5 tons (2,800-3,000 lbs)
• 1 ton of gravel ≈ 0.67-0.71 cubic yards
• 1 cubic yard covers approximately 160 sq ft at 2" deep or 80 sq ft at 4" deep

Gravel Driveway Installation Guide

Proper Layer Structure

A well-built gravel driveway has three layers:

1. Base layer (4"): Large crushed stone (#3) for drainage and stability
2. Middle layer (3"): Medium crushed stone (#57) to fill gaps
3. Top layer (2"): Fine gravel or pea gravel for finished surface

Installation Steps

1. Excavate to 8-12 inches deep
2. Install landscape fabric (optional but recommended)
3. Add and compact base layer
4. Add and compact middle layer
5. Install edging/borders
6. Spread and rake top layer
7. Light compaction of top layer

Maintenance Tips

• Rake regularly to even out displaced gravel
• Add 1-2 inches of new gravel every 1-2 years
• Fill potholes promptly to prevent expansion
• Grade for proper drainage (slope away from structures)
• Control weeds with pre-emergent herbicide or fabric
