Enter area dimensions and depth to get volume in m³, bag count and bulk delivery trucks for any landscape material.
30 m² × 0.075 m = 2.25 m³ of mulch. At 350 kg/m³ bulk density that is approximately 788 kg, or 45 × 50 L bags. This calculator works it out automatically for any area, depth and material type.
A standard 25 L bag of topsoil covers approximately 0.5 m² at 50 mm depth. For a 10 m² garden bed at 100 mm depth, you need 20 m² / (25 L / 1000 / 0.1) = 80 bags. Enter your exact dimensions in the calculator for a precise count.
Bulk delivery (typically 6 m³ truck) is cost-effective for orders of 0.5 m³ or more. Below 0.5 m³, bags from a garden centre are usually more economical as delivery charges often exceed material savings.
