Materials Calculator

These calculators are designed to give approximate amounts only. They will help you determine the quantity you need; however, variations in subgrade, compaction of subgrade, or inaccurate measurements, even a quarter of an inch of depth, can make a difference.

For gravel and decorative rock, these are recommended depths assuming normal conditions:
1 inch and below need to be around 2 inches deep, 1.5–2 inch gravel should be 3 inches, and 2–4 inch should be 4 inches deep.
The bigger the gravel size, the deeper it needs to be for good coverage.
