Coverage, bags, bulk, and delivery
One cubic yard covers 324 sq ft at 1 inch, 162 sq ft at 2 inches, or 108 sq ft at 3 inches, before any allowance. Choose your project below to turn that coverage into a material shopping list.
Start with the job, then estimate the materials together. Example quantities below exclude waste, settling and purchasing-rounding unless stated; choose depths for your own site.
If your soil-preparation plan calls for a 2-inch added layer over 500 sq ft, that is 500 × (2 ÷ 12) ÷ 27 = 3.09 cu yd before settling allowance. Adding soil is optional. Carry the same measured area between Topsoil and Sod, then choose depth and supplier roll/pallet coverage.
Plan lawn soil and sodA 200 sq ft patio at 4 inches compacted depth needs 2.47 cu yd in place. A 20% loose-volume allowance brings it to 2.96 cu yd, before supplier rounding. The Paver planner also includes bedding sand, joint sand, edging and pavers.
Plan a paver projectOne cubic yard covers 162 sq ft at 2 inches or 108 sq ft at 3 inches. A 2-cu-ft bag covers 12 sq ft at 2 inches or 8 sq ft at 3 inches. Choose depth, add your buffer, then compare rounded bags with bulk delivery.
Compare mulch bags and bulkA 4 × 8 ft bed filled 12 inches deep holds 32 cu ft, or 1.19 cu yd. Add beds with different dimensions, subtract any planned lower fill, and apply settling allowance before comparing bags and bulk.
Plan garden-bed soilMeasure the lawn, add cutting waste, then divide by the supplier’s coverage and round up. A 500 sq ft lawn with 10% waste needs 550 sq ft: 55 rolls at 10 sq ft each, or 2 whole pallets at 450 sq ft each.
Compare sod rolls and palletsA 100 sq ft area at 3 inches needs 25 cu ft, or 0.93 cu yd, before allowances. Choose waste and compaction for your use. Tons depend on material density; a bag’s weight alone does not tell you its coverage.
Estimate gravel quantitiesMeasure the area, choose an installation depth, and convert the result into cubic yards. Use the full calculators when you need irregular shapes, multiple areas, waste, settling, compaction, bags, or pricing.
Measure length x width.
Measure the diameter.
Measure base and height.
Divide the project into simple shapes, measure each section, and add the totals.
Record measurements in feet. Divide inches by 12 to convert them to feet.
| Project | Depth |
|---|---|
| Refresh existing mulch | about 2 inches |
| New mulch layer | about 3 inches |
| Lawn topdressing | about 1/4 to 1/2 inch |
| Decorative gravel | often about 2 to 3 inches |
| Filling or leveling soil | depends on the low area |
| Paver base | depends on project use, soil, and local conditions |
These are planning starting points, not universal installation requirements.
Area × Depth in feet ÷ 27 = Cubic yards
Already have your measurements? Skip the manual math and use the exact calculator for your project.
One cubic yard covers less area as installed depth increases.
| Installed Depth | Coverage from 1 Cubic Yard |
|---|---|
| 1 inch | 324 sq ft |
| 2 inches | 162 sq ft |
| 3 inches | 108 sq ft |
| 4 inches | 81 sq ft |
| 5 inches | about 65 sq ft |
| 6 inches | 54 sq ft |
Add extra for compaction, settling, uneven ground, and installation waste.
Different materials use different buying units. The calculators handle exact quantities, but this gives you the buying language to expect.
| Material | Common Buying Units | What to Confirm Before Buying | Calculator |
|---|---|---|---|
| Mulch | Bags or cubic yards | Bag volume and settling | Mulch Calculator |
| Topsoil | Bags or cubic yards | Settling and moisture | Topsoil Calculator |
| Gravel | Bags, cubic yards, or tons | Density and delivery weight | Gravel Calculator |
| Raised Bed Soil | Bags or cubic yards | Fill reduction and settling | Raised Bed Soil Calculator |
| Sod | Square feet, rolls, or pallets | Square feet per roll or pallet | Sod Calculator |
| Pavers | Pieces or pallets | Pieces per pallet and waste | Paver Calculator |
Use the bag volume printed on the product label. Not every material is sold in every size.

0.5 cu ft is sometimes used as a volume reference for bagged stone or sand, though many products are labeled primarily by weight.
The calculated volume is the starting point. Real projects often need a small adjustment before purchasing.
Add extra for cuts, curves, spills, and measurement uncertainty.
Order enough loose gravel to achieve the required compacted depth.
Allow for material settling after installation.
The right adjustment depends on the material and project. The full calculators include project-specific settings.

Quick rule of thumb
Price both options when your project needs about 1/2 to 1 1/2 cubic yards.
Volume tells you how much space the material takes. Weight determines whether your vehicle can safely carry or tow it.
Best for smaller or lighter loads. Check the vehicle payload before loading.
Useful when the load is too large for a pickup bed and your vehicle can tow it safely. Check trailer capacity, hitch rating, axle limits, and tow rating.
Usually the best option for large or dense orders such as gravel, sand, or wet soil.
Check vehicle payload, trailer capacity, hitch rating, axle limits, and tow rating. Do not judge only by whether the material physically fits.

Measure length and width in feet, multiply by depth in feet, then divide cubic feet by 27.
One cubic yard is 27 cubic feet, so 13.5 two-cubic-foot bags are equivalent. Buy 14 whole bags.
Bags are often easier for small projects or difficult access. Bulk can make sense for larger projects when delivery and staging space work.
It depends on the material and layout. Add for cuts, curves, compaction, settling, uneven ground, and measurement uncertainty.
Do not judge by volume alone. Check payload, axle, trailer, hitch, and tow ratings, especially for gravel, sand, or wet soil.
