Landscaping Calculators

Free tools for gardeners, landscapers & hardscape DIYers. Calculate materials for mulch beds, gravel driveways, paver patios & retaining walls — all with real-time results.

Plan Your Outdoor Project With Confidence

Landscaping material estimates are notoriously tricky. Order too little and your project stalls mid-way. Order too much and you're stuck with a pile of leftover gravel or mulch taking up driveway space. Our landscaping calculators take the guesswork out — each one factors in standard depths, material densities, and waste percentages so you get a reliable number the first time.

These tools handle the three big outdoor project categories: softscaping (mulch, soil, compost), hardscaping (gravel, pavers, retaining walls), and drainage (base layers, backfill). Every calculator comes with a companion article covering best practices, common mistakes, and professional installation tips.
