LandscapeYardage.com provides free calculators for estimating landscape materials — mulch, gravel, topsoil, river rock, pavers, and more — in cubic yards, tons, and bags.
Why we built this site
Ordering landscape material is one of those jobs where a small math mistake gets expensive fast: order too little and you pay a second delivery fee, order too much and you are left with a pile you cannot return. Our calculators show the exact formula behind every estimate, so you can verify the numbers yourself before you buy.
How our calculators work
Every tool on this site uses the standard volume formula — length × width × depth ÷ 27 — combined with published material density figures to convert between cubic yards, tons, and bag counts. We cite the density assumptions on each calculator page and update them when supplier specifications change.
