Calculate soil in cubic feet from common site dimensions. Review totals, waste, and coverage instantly. Export clean reports for estimating, ordering, and job planning.
The calculator first finds the area of the selected shape.
Rectangle area = length × width.
Circle area = π × radius².
Triangle area = 0.5 × base × height.
Trapezoid area = ((top width + bottom width) ÷ 2) × length.
Net cubic feet = area × depth × quantity.
Waste volume = net cubic feet × waste percentage.
Final cubic feet = (net volume + waste) × adjustment factor.
Estimated weight = final cubic feet × soil density.
| Project | Shape | Dimensions | Depth | Estimated Volume |
|---|---|---|---|---|
| Garden Bed | Rectangle | 12 ft × 4 ft | 0.5 ft | 24.00 cu ft |
| Round Planter | Circle | 8 ft diameter | 0.75 ft | 37.70 cu ft |
| Entry Fill Area | Trapezoid | 10 ft length, 6 ft bottom, 4 ft top | 0.5 ft | 25.00 cu ft |
Construction work often starts with volume planning. Soil is usually moved, bought, or removed by volume. Cubic feet gives a direct way to measure that volume. It helps when you plan beds, trenches, backfill zones, and small site grading jobs. It is also useful when suppliers list bags or loose material in smaller units.
Small mistakes in dimensions can create large ordering errors. A shallow fill across a wide area still adds up fast. Overordering raises hauling and storage costs. Underordering slows work and creates extra delivery charges. A calculator helps you check the numbers before you place an order. It also helps estimators explain quantities clearly to clients and crews.
This calculator supports several common shapes. It converts dimensions into feet, then calculates soil volume in cubic feet. It also shows cubic yards and cubic meters. That makes the result easier to compare with supplier quotes. Waste percentage is included because real projects rarely match perfect geometry. Adjustment percentage can be used for compaction or swell. Density is included for weight planning.
You can use this page for landscape beds, trench fill, planter boxes, slab edge fill, and excavation replacement. It works for one area or repeated sections with the quantity field. It is especially helpful on jobs where site notes use mixed units. The conversion happens inside the calculator, so the workflow stays simple.
Measure twice before you order. Use average dimensions if the area is irregular. Add realistic waste instead of guessing. Check whether the material will compact after placement. If you need truck planning, review the weight result too. These steps give cleaner estimates and fewer surprises on site.
Cubic feet measures the total soil volume needed to fill a space. It combines area and depth into one practical construction quantity.
Use waste percentage when you expect spillage, uneven grading, settling, trimming, or measurement uncertainty. It helps prevent underordering.
Many bulk suppliers quote soil in cubic yards. Showing both units helps you compare site calculations with supplier pricing faster.
It lets you increase or decrease the final volume for compaction, swell, or special project conditions after waste is applied.
Yes. Depth can be entered in inches, feet, yards, meters, or centimeters. The calculator converts everything automatically.
Enter the density your supplier gives you. If you only need volume, you can still calculate without changing the default density.
Yes. The page estimates how many half-cubic-foot and one-cubic-foot bags are needed from the final adjusted volume.
Yes, by splitting the site into simple shapes. Calculate each section separately, then combine the totals for a better estimate.
