Landscaping material calculators for Oregon
Put in the job dimensions, then calculate the amount to order. Use this quick estimator, or go to the calculator for your chosen material to see depth advice, coverage details, and example jobs.
Add your job measurements
A cubic yard fills a cube measuring 3 x 3 x 3 feet. Bulk products are ordered by that volume or by the ton, so the job is turning your project area into either unit. These tools calculate that for 24 stocked products using each product's weight per cubic yard. Shredded mulch runs about 600 lb for a yard, while crusher run comes in at 3,000 lb. The cube size is the same, but crusher run weighs five times as much, so a calculator tied to the material gives a better tonnage figure than a general aggregate tool.

Calculation method
Find the square footage first by multiplying the length and width in feet. Change depth from inches to feet by dividing by 12, then multiply it by the area for cubic feet. Divide that figure by 27 to get cubic yards. Apply the material density to the yardage to determine tons.
Tons = cubic yards × density (0.3 for mulch, up to 1.55 for riprap)
Most estimate mistakes come from the depth. Area gets measured carefully, but depth is often guessed. A 10 x 10 patio at 2 inches uses half the stone required for the same patio at 4 inches. Check the material page first when you need the proper depth for the job.

| 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 area, figure the lower crusher run or road base separately from the top layer of driveway gravel or #57 stone. Each layer needs its own calculation.
- For pooled water, wet trenches, or a French drain through winter clay, allow clean #57 or drain rock at 12 inches or deeper.
- Put shredded mulch in beds with plants. Choose river rock for a border that does not require regular refreshing.
- For a bare or patchy lawn, spread 4 to 6 inches of screened topsoil before installing seed or sod.
- Use fill dirt to build grade or fill a hole, then limit topsoil to the upper 4 to 6 inches.
- Build a paver patio with compacted base and an exact 1 inch bedding-sand layer. Calculate the base and sand as separate layers with the paver tools.
- Playground fall areas: maintain pea gravel at a depth of 9 to 12 inches.
- For an eroding bank or shoreline, install riprap over fabric in layers of 12 inches or more.
