How it works

Depth presets are conveniences; any custom depth works. Bag size always comes from the shelf.

Calculate quantities
Cubic feet and yards, bag counts, and where sourced data exists, tonnage — with the math visible.

Compare bagged vs bulk cost from your own prices, then copy, print or reset the summary.

Frequently asked questions
Are the calculators free?
Yes — every calculator on the site is completely free, with no account or sign-up.
Are my measurements kept private?
Yes. All calculations happen entirely inside your browser. We never receive the dimensions or prices you enter.
How accurate are the estimates?
Unit math (square feet, cubic yards, short tons) is exact. Real-world quantities still vary with moisture, compaction and how the supplier packs or delivers — every result is framed as a planning estimate, and the methodology page shows the formulas.
Do the calculators use US or metric units?
US customary by default (feet, inches, cubic feet, cubic yards, US short tons); metric equivalents are shown using exact conversions.
Can I use it on my phone in a store?
It is built mobile-first, and the results panel has a Copy button that puts the whole order summary on your clipboard — handy at the garden-center counter.
Why add a waste allowance?
Small measurement errors, spillage and settling add up — a 10% allowance is a common cushion. It is adjustable (including off) and shown separately from the base quantity.
