Topsoil Calculator

How to measure your area

1. For rectangles: area = length × width. For circles: area = π × r².
2. For lawns, measure sections and add them for total area.
3. Convert depth to feet (in ÷ 12) or meters (cm ÷ 100).

Assumptions to double-check

• Use average depth—topdressing and leveling often vary across the area.
• If you’re filling low spots, include extra volume for those areas.
• Bulk topsoil may settle; a buffer prevents running short.

Buying tips

• Confirm whether you need screened topsoil for a smoother finish.
• Round up to delivery minimums and keep a small amount for touch-ups.
• If you add compost, adjust the mix ratio and volume accordingly.
