Soil, mulch & gravel volume

MEASURE FIRST

How to prepare your inputs

Break garden areas into rectangles or triangles and enter the combined area. Obtain material depth, density and bag coverage from your supplier.

How this calculation works

Volume = length × width × depth mm ÷ 1,000. Add order allowance. Mass = order volume × entered bulk density.

Assumptions & exclusions

Density is an illustrative placeholder. Soil, mulch and gravel have different moisture and bulk density. Obtain supplier values. This is not a compaction conversion or vehicle payload check.

Your next step

Confirm drainage, delivery access, finished levels, compaction and material suitability with your landscaper.

What if my shape or product is different?

Use dimensions and product data that match the stated method. For complex work, calculate separate sections or obtain a project-specific take-off. Do not apply simple geometry to structural or compliance decisions.

Why are quantities rounded up?

Whole bags, packs, sheets or cartridges round up to purchasable units. Decimal area or volume results are planning figures; confirm order increments with the supplier.
