A cubic yard is a cube measuring 3 x 3 x 3 feet. Bulk material is ordered by the yard or by the ton, so the job is to turn your project area into one of those units. These calculators handle that for 24 materials, using the actual weight assigned to each cubic yard. Shredded mulch runs around 600 lb per yard, while crusher run comes in at 3,000 lb. Both fill the same cube, but one weighs five times as much. That is why the calculator needs to match the material.

Calculator method
To find volume, start with the project area and add depth. Multiply the length and width in feet. Divide the depth in inches by 12, then multiply that by the area to get cubic feet. Divide by 27 to get cubic yards, then apply the material density for tons. That is the calculation used when measurements are given over the phone.
Tons = cubic yards × density (0.3 for mulch, up to 1.55 for riprap)
A wrong depth can throw off the estimate. The area may be measured right, but depth is often guessed. A 10 x 10 patio at 2 inches takes half the stone needed for the same patio at 4 inches. If you are uncertain, check the material page for project-specific depth recommendations.

This is the information behind the calculators. Use the chart to compare materials or look over a quote from another yard:
| Material | Weight per yd³ | Tons per yd³ | Typical depth | 1 yd³ covers at 3" | Sold by |
|---|---|---|---|---|---|
| Driveway / walkway gravel | ≈ 2,800 lb | 1.40 | 2-4" (6" new drive) | 108 sq ft | Ton |
| 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 |
Pick material for the project
- For a driveway or parking pad, calculate the crusher run or road base underneath separately from the driveway gravel or #57 stone surface.
- Use clean #57 or drain rock at 12 inches or deeper for standing water, wet trenches, and French drains.
- Put shredded mulch in planting beds. For borders that do not need refreshing, use river rock.
- For a sparse or bare lawn, spread 4 to 6 inches of screened topsoil, then add seed or sod.
- Fill dirt is for building up grade or filling holes. Use topsoil only for the upper 4 to 6 inches.
- Paver patio: install compacted base, then keep bedding sand at 1 inch. Use the Paver Base and Paver Sand calculators to estimate both layers.
- For playground fall areas, maintain pea gravel at a depth of 9-12 inches.
- For a washing-out bank or shoreline, place riprap over fabric in layers at least 12 inches deep.
