About LandscapeCalc
A free online calculator built for Australian homeowners and landscapers.
What is LandscapeCalc?
LandscapeCalc is a free, easy-to-use online calculator designed specifically for Australian homeowners, landscapers, and DIY enthusiasts. We help you calculate exactly how much landscape material you need for your projects, whether that's mulch for your garden beds, soil for a new lawn, gravel for a driveway, or roadbase for a construction project.
Our calculator provides instant results in cubic metres, tonnes, bags (25L), and bulka bags (1m³), making it easy to order from any Australian landscape supplier.
Why We Built This
We've seen too many Australians either order too much material (wasting money) or too little (requiring additional deliveries). Our goal is to help you get it right the first time with accurate calculations based on Australian material densities and common project requirements.
How It Works
Simply select your material type, enter your area dimensions and desired depth, and our calculator does the rest. We use industry-standard material densities specific to Australian suppliers to ensure accurate weight conversions.
Materials We Cover
- Mulch: Wood chip, bark, pine bark, cypress, eucalyptus, and sugar cane mulch
- Soil: Topsoil, garden mix, veggie mix, turf underlay, sandy loam, and potting mix
- Gravel: Blue metal, crushed granite, river pebbles, sandstone, limestone, and decorative pebbles
- Sand: Washed sand, brickies sand, plastering sand, paving sand, and play sand
- Road Base: DGB20, DGB10, FCR, recycled roadbase, quarry rubble, and crusher dust
Accuracy & Disclaimer
Our calculator uses industry-standard material densities that are typical for Australian suppliers. However, actual material densities can vary based on:
- Moisture content
- Particle size and composition
- Source quarry or supplier
- Compaction level
We recommend adding 5-10% extra to your calculated amount to account for variations, settling, and wastage. For large or critical projects, always confirm material specifications with your supplier.
This calculator is provided for estimation purposes only. LandscapeCalc accepts no responsibility for over or under ordering of materials. Always verify quantities with your supplier before placing orders.
Independence Statement
LandscapeCalc is an independent resource and is not affiliated with any landscape supply company, quarry, or material manufacturer. We do not sell materials or receive commissions from suppliers. Our goal is simply to provide a useful, free tool for the Australian community.
