Mulch Gravel Soil Bulk Bag Estimator
Estimate how much mulch, gravel, topsoil, river rock, sand or compost a landscaping job needs. Enter the area shape (rectangle, circle, triangle or tapered bed/border), dimensions and depth, then pick a material from the built-in density table (or a custom density). The estimator returns volume (m³ / liters / yd³ / ft³), weight (kg / lb / tonnes), the count of 1 m³ or 1 yd³ bulk bags, small retail bag count, optional cost, plus depth and allowance warnings. Metric and imperial units supported.
Quick start
