Mulch & Gravel Calculator
Estimate landscape material by depth for beds, paths, and tree rings. Get bags or bulk volume, with an optional weight estimate.
Measurement system
Material
Switching material keeps your measurements — weight presets are material-specific.
Bag, waste & weight assumptions
Bag size
2 ft³ is the most common retail bag. Bulk delivery? Use the volume figures in the results.
Waste allowance
%
Mulch settles and gravel compacts — 10% covers most projects.
Presets are supplier estimates — moisture, grading, and compaction change actual weight.
Shape
Volume = length × width × depth
