Calculate Your Materials
Enter your project dimensions to estimate material quantities. Results are estimates — always add 10–15% for waste and cuts. Call us at (916) 363-4239 to verify.
Estimate includes 10% waste factor. Actual weight varies by stone type and thickness. Call us at (916) 363-4239 to confirm quantities before ordering.
Based on approximately 1.4 tons per cubic yard. Add 10–15% for settling and waste. Actual weight varies by material type.
Cobbles and pebbles are sold by the ton for bulk orders, or by the bag for smaller quantities. Call (916) 363-4239 for current pricing.
Boulder quantities are typically determined by visual selection at our yard rather than by calculation. However, here are typical usage guidelines:
| Boulder Size | Approx Weight | Typical Use |
|---|---|---|
| 6"–12" | 20–80 lbs | Accents, borders, waterfall edges |
| 12"–18" | 80–250 lbs | Garden focal points, water features |
| 18"–24" | 250–600 lbs | Walls, major water features |
| 24"–36" | 600–1,500 lbs | Retaining walls, large waterfalls |
| 36"+ | 1,500–4,000 lbs | Dramatic focal points (crane required) |
Large boulders (over ~800 lbs) typically require crane placement. We can provide a crane company referral. Call (916) 363-4239 to discuss your boulder project.
Measuring Tips
- For irregular shapes, break the area into rectangles and add them together
- For circles, measure the diameter and multiply by itself then by 0.785
- Always add 10–15% to your order for cuts, breaks, and future repairs
- Flagstone is sold by weight — actual coverage varies by stone type and thickness
- When in doubt, bring your measurements to our yard — we'll help you estimate
