🪨 Gravel Calculator

Calculate the volume and weight of gravel needed for driveways, paths, gardens, and construction projects. Supports imperial and metric with multiple gravel types.

Gravel Depth Guidelines

ApplicationRecommended Depth
Walkways / paths2 inches (5 cm)
Driveways4 inches (10 cm)
Garden beds / mulch alternative2–3 inches (5–7.5 cm)
Drainage trenches6–12 inches (15–30 cm)
Base course (road sub-base)6–8 inches (15–20 cm)
'Should I order extra gravel for waste?', 'answer' => 'Yes — order 5–10% extra to account for compaction (gravel settles 10–15% after rain/traffic), irregular subgrade depth, and spillage at edges. For large projects, add 15%. It is usually cheaper to have a small surplus than to re-order a partial load.'], ]" />
