How to calculate landscape materials
Measure each planting zone and add the areas. If one bed has different grades or depths, calculate those sections separately so the delivery amount follows the actual plan.
Choose material by purpose: topsoil supplies volume and structure, compost adds organic matter, mulch protects the surface, and gravel supports drainage or hardscape. Their densities and recommended depths are not interchangeable.
Bulk suppliers often deliver in practical increments. Round up, confirm truck access and placement, and ask whether delivery includes spreading or only the drop.
Formulas used
Cubic yards
area × depth ÷ 12 ÷ 27 × 1.05Converts depth to cubic yards and adds five percent for settling.
Material weight
cubic_yards × material_densityEstimates weight for delivery and handling conversations.
Frequently asked questions
What to know before you order.
How much topsoil do I need?
Multiply the bed area by the desired depth, convert the volume to cubic yards, and round to the supplier's delivery increment.
Should I choose topsoil or compost?
Topsoil provides bulk and structure; compost contributes organic matter. The right blend depends on existing soil and the planting plan.
Can one calculator cover mulch and gravel?
Yes for volume planning, but material density, depth, price, and the site use must still be checked separately.
