About YardPlanHQ

YardPlanHQ is a free collection of practical landscaping calculators that help homeowners, DIYers, gardeners and small landscaping contractors estimate the materials they need for outdoor projects before they order.

What we make

Every tool on this site answers one real question with numbers you can act on — how much mulch a bed needs, how much pea gravel a path or driveway needs, or how much soil fills a raised bed. Each calculator shows the full result breakdown: base volume, waste allowance, adjusted total in cubic feet and cubic yards, bag counts for the bag size you choose, and cost estimates built from the prices you enter. We never show an invented price or a weight without a real density figure.

How it works

• All calculations run entirely inside your browser. The dimensions you enter are never sent to a server.
• No account or sign-up is required. Open the site, calculate, copy or print the result, order.
• Unit conversions use exact mathematical constants — 12 inches per foot, 27 cubic feet per cubic yard, 2,000 pounds per US short ton.
• Variable quantities (bag rounding, material density, actual delivered packaging) are always estimated transparently and labeled as such.

Why these estimates vary

Real-world material quantities depend on product specifications, moisture, compaction, site conditions, installation practices and supplier packaging. Treat every result as a planning figure and confirm final quantities with your supplier — the calculators are deliberately honest about that. For full details see Calculation Methodology.

Questions or corrections?

We want these numbers to be right. If you spot an error, tell us via the contact page. Corrections are always welcome and are applied to the calculation engine, not just the copy.
