Add project measurements
One cubic yard fills a cube measuring 3 x 3 x 3 feet. We sell bulk materials by cubic yard or ton, so ordering starts with turning the project area into one of those measures. These calculators make that conversion for 24 stocked products using each product's actual cubic-yard weight. Shredded mulch is about 600 lb per yard, while crusher run is 3,000 lb. The cubes are equal in size, but crusher run is five times heavier. A general aggregate calculator can miss that tonnage difference; a product-based calculator accounts for it.

Calculation method
First, multiply the length and width in feet. Multiply that result by the depth in feet, found by dividing inches by 12, to get cubic feet. Divide by 27 to get cubic yards. Then apply the material density to find tons. That is the same calculation used when project measurements are called in.
Tons = cubic yards × density (0.3 for mulch, up to 1.55 for riprap)
Most estimate errors come from the depth, not the area. For example, a 10 x 10 patio with 2 inches of stone takes half the material needed for that patio at 4 inches. If you are not sure on depth, check the project guidance on the material page first.

| Pea gravel (3/8") | ≈ 2,800 lb | 1.40 | 2-3" | 108 sq ft | Ton |
| Crushed stone #57 / 3/4" | ≈ 2,800 lb | 1.40 | 2-4" | 108 sq ft | Ton |
| Crusher run / road base | ≈ 3,000 lb | 1.50 | 4" compacted | 108 sq ft | Ton |
| River rock (1-3") | ≈ 2,700 lb | 1.35 | 2-4" by size | 108 sq ft | Ton |
| Mason / washed sand | ≈ 2,700 lb | 1.35 | 1-6" by use | 108 sq ft | Ton |
| Topsoil (screened) | ≈ 2,200 lb | 1.10 | 2-6" | 108 sq ft | Yard |
| Garden soil (blended) | ≈ 2,000 lb | 1.00 | 4-12" by bed | 108 sq ft | Yard |
| Fill dirt | ≈ 2,400 lb | 1.20 | as needed | 108 sq ft | Yard |
| Shredded mulch | ≈ 600 lb | 0.30 | 2-3" | 108 sq ft | Yard |
| RipRap / armor stone | ≈ 3,100 lb | 1.55 | 12"+ layers | n/a | Ton |
Find the right material
- For a new driveway or parking pad, figure the crusher run or road base below separately from the driveway gravel or #57 stone above. Use two calculators, one for each layer.
- For standing water, a wet trench, or a French drain, plan on clean #57 or drain rock at 12 inches or more.
- Put shredded mulch in planting areas. Choose river rock for borders that are not regularly refreshed.
- For a bare or sparse lawn, place 4 to 6 inches of screened topsoil before laying seed or sod.
- Fill dirt is used to raise grade or fill low spots. Use topsoil only for the upper 4 to 6 inches.
- A paver patio needs a compacted base beneath a strict 1 inch layer of bedding sand. Calculate those layers separately with the Paver Base and Paver Sand calculators.
- Playground fall zones need pea gravel maintained at 9 to 12 inches deep.
- Where a bank or shoreline is washing away, place riprap over fabric in layers of 12 inches or more.
