Formula
length × width × depth = volume; convert inches to feet before multiplying
A 10–15% buffer is useful for gravel because compaction and uneven subgrade can increase material needs.
Quick reference
| Project size | Common use | Planning note |
|---|---|---|
| 100 sq ft | Small bed or walkway | Good for testing bagged material prices |
| 250 sq ft | Medium garden or patio area | Bulk delivery may start making sense |
| 500 sq ft | Large lawn, driveway, or landscape zone | Measure carefully and add a buffer |
FAQ
How deep should gravel be for a walkway?
A decorative walkway is often 2–3 inches deep. A driveway or load-bearing area usually needs a deeper compacted base.
Should I order gravel by cubic yards or tons?
Suppliers often sell bulk gravel by tons, but measuring the area in cubic yards is the easiest first estimate.
