Garden Estimate is a collection of 10 free calculators built for home gardeners. Whether you’re measuring mulch for a new bed, planning plant spacing, or figuring out when to start seeds indoors, Garden Estimate gives you instant answers — no account, no ads in the way.
We cover the calculations most gardeners reach for every season: mulch and soil volumes, paver counts, compost quantities, frost dates by zip code, plant spacing, lawn fertiliser, seed starting dates, garden bed dimensions, and raised bed lumber estimates.
