How much topsoil do you need?
Enter area and soil depth to calculate cubic yards, bag counts, and coverage.
Enter your measurements
Measure the area you plan to cover. Soil settling depends on moisture, texture, and project conditions; use a suitable allowance.
Your estimate
Enter your dimensions to see your material estimate.
Calculate first. Order with confidence.
Length × width × depth (in feet) ÷ 27 = cubic yards. A bag estimate uses your chosen bag volume in cubic feet and rounds up.
Results are estimates, not a substitute for checking on-site dimensions, local requirements, packaging labels, or supplier specifications. Cost fields do not include delivery, taxes or labor unless you incorporate them into your entered price.
Understand the calculationsKnow what is included
Volume conversions use 27 cubic feet per cubic yard. Concrete bag-yield presets come from the QUIKRETE Concrete Mix No. 1101 data sheet. Gravel bulk-density values are editable examples—not universal constants.

How much topsoil do I need for a garden bed?
Multiply the bed length and width in feet by the desired depth in feet. Divide by 27 for cubic yards and add a reasonable allowance.
How many bags of topsoil are in a cubic yard?
That depends on the bag’s labeled volume. One cubic yard is 27 cubic feet, so 27 bags of 1 cubic foot each is the theoretical equivalent before extra allowance.
Does this calculate topsoil weight in tons?
No. Soil weight changes substantially with moisture and material. Ask the supplier for its current tons-per-yard conversion.
