LEAF & LODGE · FREE GARDEN TOOLS
Work out how much garden soil, raised-bed mix, compost or topsoil your project needs. Use these free calculators to estimate quantities before you buy, so you can plan your garden with more confidence and less guesswork.
Find the right calculator ↓Start with the material you need and the kind of project you are planning. Each tool opens its own calculator page, keeping its existing features separate and unchanged.
Estimate the soil volume for a garden plot or planting area using your measurements. Use the result to help plan how much material to order.
Plan the amount of soil mix for a raised garden bed. Measure the inside dimensions and use the dedicated tool to estimate the fill you need.
Estimate compost for vegetable beds, flower borders, lawn top-dressing or soil improvement. Choose an application depth and enter your area.
Calculate topsoil volume from length, width and depth, then review estimated weight, pickup loads, bag quantities and example bulk costs.
For a rectangular area, volume is based on length × width × depth. Keep measurements in compatible units and convert depth to feet when calculating cubic feet. For example, a 10 ft × 4 ft bed filled to 1 ft deep has a volume of 40 cubic feet before allowing for settling or changes in the bed shape.
Measure the inside length and width of a raised bed, or the garden area you want to cover.
Decide how deep the material should be. Compost top-dressing and filling a new raised bed are different jobs.
Use the relevant calculator's volume estimate to plan bag quantities or discuss a bulk order with your local supplier.
Choose the tool that matches the material and task. Garden soil and raised-bed mix are generally used to fill growing spaces; compost is often applied as an amendment or surface layer; topsoil is commonly used to build up or level soil areas. Check product descriptions and local growing recommendations before choosing a material.
If you are filling a raised bed, start with the Raised Bed Soil Calculator. If you are spreading compost over an established bed or lawn, use the Compost Calculator. For a topsoil delivery or a garden area that needs additional topsoil, use the Topsoil Calculator. For a general garden plot, begin with the Garden Soil Calculator.
For a rectangular space, multiply length by width by depth after converting all measurements to the same unit. If dimensions are in feet, the result is cubic feet. Divide cubic feet by 27 to convert to cubic yards.
One cubic yard equals 27 cubic feet. Bag labels and bulk suppliers may use different units, so check the units shown in the calculator and on the product before ordering.
Consider an allowance if the ground is uneven, the material may settle, or the bed dimensions are approximate. The right allowance depends on your project and supplier, so avoid treating one percentage as universal.
Not automatically. Compost is usually an organic amendment, while garden soil and raised-bed mixes are intended to provide a growing medium. Many projects use compost as one part of a soil mix rather than as the entire fill; follow plant needs and product instructions.
No. Results are planning estimates. Actual quantities can differ because of irregular shapes, settling, compaction, moisture and how suppliers measure or deliver material. Confirm quantities and delivery requirements with your supplier.
