Add your project measurements
Think of a cubic yard as a cube measuring 3 x 3 x 3 feet. Bulk materials are sold by the cubic yard or by ton, so ordering starts with turning your project area into one of those units. These tools calculate quantities for 24 stocked products using the actual weight of each cubic yard. Shredded mulch weighs about 600 lb per yard. Crusher run weighs 3,000 lb per yard. Both occupy the same cube, but crusher run is five times heavier, so a calculator matched to the material gives a more accurate tonnage than a general aggregate calculator.
Pick a material
Calculation method
Start by multiplying the length and width in feet. Convert depth from inches to feet by dividing by 12, then multiply it by the area to find cubic feet. Divide that total by 27 to find cubic yards. Apply the material density to the yardage to determine tons. This is the same calculation used when measurements are provided by phone.
Tons = cubic yards × density (0.3 for mulch, up to 1.55 for riprap)
Getting the depth right matters as much as measuring the area. A 10 x 10 patio at 2 inches uses half as much stone as that patio at 4 inches. Check the recommended project depths on each material page before estimating if you are not sure.
Compare all 24 materials
The calculators use the figures in this chart. It can also help you compare material options or review 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 |
Find the right material
- For a driveway or parking pad, place crusher run or road base below, then use driveway gravel or #57 stone as the top layer. Calculate the two layers separately.
- Use clean #57 or drain rock for pooling water, wet trenches, and French drains. Plan for 12 inches or more.
- Put shredded mulch in planted beds. Choose river rock for a border that does not need regular refreshing.
- Bare or sparse lawn: spread 4 to 6 inches of screened topsoil before adding seed or sod.
- To build up grade or fill a hole, use fill dirt for the main fill. Reserve topsoil for only the upper 4 to 6 inches.
- A paver patio calls for compacted base with an even 1 inch bedding-sand layer. Use the Paver Base and Paver Sand calculators to estimate each layer on its own.
- For playground fall areas, keep pea gravel at a maintained depth of 9 to 12 inches.
- For an eroding bank or shoreline, install riprap over fabric in layers of 12 inches or more.
