How to calculate crushed stone for any project (2026)
Whether you're planning a new driveway, patio base, retaining wall backfill, or walkway, using a crushed stone calculator ensures you buy exactly the right amount. Overordering wastes money, underordering causes project delays. Our 3/4 crushed stone calculator and crusher run stone calculator are designed for US homeowners, landscapers, and contractors.
Why use a crushed stone calculator?
Manual estimation often leads to errors. Our crushed stone calculator in tons applies the industry formula: Volume (cubic yards) × Material Density (tons/yd³) = Tons needed. We incorporate shape (rectangle/circle), depth, and waste factor. Whether you need how much crushed stone do i need calculator for a 20x10 driveway or a 12-ft round fire pit area, we've got you covered.
Step-by-step: calculate crushed stone for driveway & patio
Length × Width (rectangle) or π × r² (circle)
Depth (inches) ÷ 12 = depth in feet
Then ÷ 27 → cubic yards
Add waste factor (5-15%)
Crushed stone coverage & tonnage reference table
| Stone type | Density (tons/yd³) | Coverage at 2” depth (sq ft per ton) | Coverage at 4” depth (sq ft per ton) |
|---|---|---|---|
| 3/4" crushed stone | 1.4 | ~115 sq ft | ~57 sq ft |
| #57 stone (¾" clean) | 1.35 | ~120 sq ft | ~60 sq ft |
| Crusher run (3/4" minus) | 1.5 | ~108 sq ft | ~54 sq ft |
| ½" crushed stone | 1.3 | ~124 sq ft | ~62 sq ft |
| 2" crushed stone | 1.4 | ~115 sq ft | ~57 sq ft |
*Estimates based on compacted base. Use calculator for exact project numbers.
3/4 crushed stone calculator vs. crusher run: which to choose?
3/4 inch crushed stone is angular, ideal for drainage and driveways. Crusher run (3/4" minus with fines) compacts better for solid bases. Use our crushed stone base calculator to adjust density. For crushed stone driveway calculator, we recommend crusher run base (1.5 tons/yd³) topped with clean 3/4 stone for aesthetics. Also our crushed stone patio calculator works perfectly for paver bases.
Original insight: 2026 material cost & delivery trends
Based on Q1 2026 market analysis, average crushed stone prices range $35–$65 per ton depending on region (Midwest, Northeast, South). Add delivery fees ~$100–$200. Our calculator helps you request accurate quotes from suppliers like Home Depot, Lowe’s, or local quarries. Use crushed stone cost calculator feature: simply multiply tons × local price per ton. For example, 8.5 tons × $50 = $425 material cost.
How to calculate crushed stone for circle / round area
Many fire pits and garden circles require a crushed stone calculator circle. Formula: radius² × π × depth (ft) ÷ 27 = cubic yards. Our built-in shape switcher handles it automatically. Perfect for DIY landscapes.
Quick checklist before ordering crushed stone
- ✓ Confirm measurements – double-check length, width, depth (inches).
- ✓ Select correct stone type – 3/4" for drainage, #57 for septic, crusher run for base.
- ✓ Add waste factor – 10% minimum for irregular shapes or compaction.
- ✓ Check local delivery – ask about “tri-axle” vs “pickup” load limits.
- ✓ Consider depth – Driveways require 4–6 inches base; patios 4 inches.
Metric conversion? Not needed for US projects
Our crushed stone calculator yards and tons output is US customary. If you're working with cubic feet, we display that too. Crushed stone yard calculator helps landscape architects.
Common crushed stone sizes & applications
- 3/4 inch crushed stone – driveways, French drains, pathways
- #57 stone (3/4" clean) – concrete aggregate, drainage
- Crusher run / 3/4" minus – base material for pavers, roads
- 1/2 inch crushed stone – walkways, playground surfaces
- 2" crushed stone – large drainage, heavy base layers
- 3/8 crushed stone – underlayment for artificial turf
Our calculator supports all these via custom density selection. You can also manually enter density if known.
