Shed, patio, and wall base
Size gravel for a shed foundation, compacted patio base, bedding and joint sand, and block for hardscape projects.
Calculator index
Every calculator turns a measured area and a depth or rate into cubic yards, tons, bags, waste, and a printable material list. Pick a project below to get a planning estimate before you buy bags or order a bulk load.
Popular planning routes
Patios, walls, paths & driveways
Estimate base gravel, bedding sand, blocks, mortar, and decorative or driveway stone for hardscape projects.
Beds, lawns, soil & compost
Estimate soil, compost, mulch, grass, sod, and fill for beds, raised boxes, lawns, and grading.
Project paths
Size gravel for a shed foundation, compacted patio base, bedding and joint sand, and block for hardscape projects.
Estimate the cover, amendment, and soil volumes for beds, borders, and raised boxes.
Compare seed, sod, topsoil, and fill quantities before repairing bare or uneven areas.
Start with the general gravel calculator for yards and tons, or choose a focused tool for decorative stone, paths, and driveways.
Need a chart before choosing a calculator? The yard material coverage chart shows how far one cubic yard spreads at common depths, typical tons per cubic yard by material, and how many bags equal one cubic yard. Use it as a quick check, then open the calculator for the project-specific waste, density, and bag-size settings.
Most yard projects come down to area times depth. If you are filling, covering, or topping something — gravel, soil, mulch, compost, or paver base — start with the calculator for that material, enter the length, width, and depth, and read the cubic yards and bag count. Walls and lawns work a little differently: the concrete block calculator works from wall face area, and the grass seed calculator works from a seeding rate per 1,000 square feet.
If a project needs more than one material, use a few calculators together. A patio, for example, usually pairs the paver base calculator for base gravel and bedding sand with edging and pavers you measure separately. A new raised bed pairs the raised bed soil calculator with the compost calculator to plan the blend.
Each page shows the formula and the default assumptions it used, converts the result into cubic feet, cubic yards, tons, and bag counts, and builds a plain material list you can print or copy. A quick-reference table on each page shows coverage or rates at common depths. Everything is a planning estimate: supplier density, moisture, bag fill, and site conditions vary, so confirm the final amount with the product label or your local supplier before buying.
