Topsoil Calculator
Spread a new soil layer for sod or planting. Enter bed dimensions and depth to get cubic yards or meters.
Step 1: Units
Step 2
Enter project measurements
Use decimals if needed (e.g. 3.5).
Step 3
How to use this calculator
Measure the coverage rectangle and average depth you want after compaction. Deeper sections can be averaged or split into multiple runs.
What the math is doing
Volume is length × width × depth. Weight multiplies volume by a typical bulk density for that material.
How to measure
Stake the area and run a string line for straight edges. Depth is from existing grade to finished grade.
Frequently asked questions
How deep for lawns?
Often 4–6 in of good topsoil over prepared subgrade.
Screened vs unscreened?
Screened is easier to rake; volume math is the same.
Blend with compost?
Treat blends as similar density for quantity planning.
Raised beds?
Use interior box dimensions for each bed section.
