Landscaping material calculators for Utah
Begin with the dimensions of your project to estimate the amount needed. For depth guidance, coverage charts, and examples, you can also open the calculator for the material you selected.
Add project measurements
Bulk materials are measured by cubic yard or ton. A cubic yard fills a cube 3 x 3 x 3 feet, so the ordering step is to turn your project area into one of those units. These calculators handle that for 24 specific products, using each material's actual weight per cubic yard. Shredded mulch weighs around 600 lb per yard, while crusher run weighs 3,000 lb per yard. The cube is the same size, but one weighs five times more, so material-specific calculations give a different tonnage result than a general aggregate calculator.

Calculation steps
Start by finding square footage: multiply the length and width in feet. Convert depth to feet by dividing inches by 12, then multiply by the area for cubic feet. Divide that result by 27 to find cubic yards, then use the material density to calculate tons.
Tons = cubic yards × density (0.3 for mulch, up to 1.55 for riprap)
An accurate depth matters because it can change the total substantially. A 10 x 10 patio at 2 inches requires half the stone needed for that same patio at 4 inches. If the right depth is unclear, refer first to the project depth listed on the material page.

The calculators use the figures in this chart. Use it to compare material weights 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, calculate the lower crusher run or road base layer separately from the driveway gravel or #57 stone finish.
- Use clean #57 or drain rock at 12 inches or more for standing water, a wet trench, or a French drain.
- Use shredded mulch in planted areas, or choose river rock for borders that do not require regular replacement.
- For sparse grass or bare ground, spread 4 to 6 inches of screened topsoil, followed by seed or sod.
- When filling a hole or raising the grade, use fill dirt for the supporting layer. Use topsoil only for the upper 4 to 6 inches.
- A paver patio needs a compacted base and an even 1 inch layer of bedding sand. The Paver Base and Paver Sand calculators measure these layers separately.
- Playground fall zones: maintain pea gravel at a depth of 9 to 12 inches.
- For an eroding shoreline or slope, install riprap over fabric in layers of 12 inches or more.
