Frequently Asked Questions
Common questions about topsoil calculation and ordering.
How accurate is the topsoil estimate?
The calculator assumes flat areas and even depth. This is ideal for planning and ordering. Very uneven ground or heavy compaction may need a small extra safety margin, which you can add with the waste factor.
What depth of topsoil should I use for lawns?
Topdressing often uses a shallow layer (0.5-1 inch), while new turf or seed needs more depth. Many gardeners work between 3–6 inches depending on soil quality and whether they are levelling or building up a new surface.
How much topsoil do raised beds usually need?
Raised beds typically use the full depth of the bed, often 8–12 inches or more. The calculator can handle multiple beds at once so you can see a combined volume for your order.
What is the waste factor and why should I add it?
A small waste factor (for example 5–15%) covers spillage, settling, and low spots that only appear once you start spreading soil. It is easier to have a little extra than to run short near the end of a job.
Can I switch between metric and imperial units?
Yes. You can work in feet and inches or meters and centimetres. The calculator converts behind the scenes so your final volume is consistent in cubic yards or cubic meters.
Does soil type (loam, sand, compost mix) change the volume?
Volume depends only on area and depth. Soil type matters for drainage, nutrients, and weight, but one cubic yard still fills the same space regardless of whether it is sandy or rich loam.
Can I use this for slope or banks?
For gentle slopes you can still use plan measurements and a chosen depth. Very steep banks may need a local contractor to confirm volumes because extra soil is often required to stabilise the slope.
How do I convert the result into bags or bulk bags?
Many suppliers sell in 25 L, 40 L, or 50 L bags and in large bulk bags. Enter your preferred bag volume in the calculator and it will show how many bags match your total.
Can I estimate truckloads from the calculator result?
Yes. Once you know the volume in cubic yards or cubic meters you can compare it with your supplier's truck capacity (for example 1 yd³, 3 yd³, or more) and see how many loads are likely to be needed.
Is this calculator suitable for professional quotes?
Many landscapers and contractors use volume calculators like this as a starting point for quotes. You can export the figures into your own pricing sheets, then adjust for labour, access, and local material prices.
