Landscaping Calculators & Guides

Plan common landscaping material quantities before ordering. These tools convert dimensions and coverage requirements into practical volume, weight or bag estimates.

Tools in this section

Topsoil Calculator

Estimate topsoil volume in cubic yards, cubic feet and cubic meters, with an ordering allowance.

Mulch Calculator

Calculate mulch volume and approximate bag counts for beds and planting areas.

Gravel Calculator

Estimate gravel volume and approximate weight for paths, beds and base layers.

Compost & Soil Mix

Calculate a blended volume from soil and compost proportions for raised beds.

Gravel & Road Base

Estimate aggregate volume and approximate weight for sub-base applications.

Mulch Coverage

Estimate mulch coverage from area, depth and package size.

Sod Calculator

Estimate turf area and pallet or roll quantities from lawn dimensions.

How to use these estimates

Start with measured dimensions and the actual product specifications where available. Volume is calculated from the geometry you enter; weight is then estimated using an assumed bulk density. Packaging, moisture, grading, compaction and supplier practices can change the final quantity.

Ordering note: Use the calculator result as a planning quantity. Before placing an order, compare it with the supplier's stated coverage, bag volume, pallet count or bulk-density information.
