Approximate volume

7.69 cu yd

High confidence

About 1.3 short tons per cubic yard for rounded pea gravel; rounded stone packs less densely than angular crushed stone. The inverse of the volume-to-weight figure. Compare against your compacted or settled requirement rather than the loose delivered figure.

Conversion factor applied
0.77 cu yd per short tons

A pea gravel tonnage converts to a slightly larger volume than crushed stone would, because rounded particles pack more loosely. The practical question is usually depth over an area, and pea gravel is generally laid shallower than angular aggregate for walking surfaces because deeper layers become difficult to walk on — the stones roll rather than key together. Where a firm surface is wanted, angular material or a bound system serves better, and the tonnage is better spent there than on more depth of loose round stone.

Add the equipment this sizes

This result is a specification — 7.692 cu yd — not a quantity. Put the thing it sizes into your project: how many, what you call it, and your supplier’s price.

Preliminary estimate, not certified engineering. This tool produces an indicative quantity calculation for planning purposes only — it is not a certified structural analysis, a guaranteed material takeoff, or a substitute for building department approval. Always verify measurements on-site and have a licensed contractor or structural engineer review any load-bearing, code-sensitive, or safety-critical work before purchasing materials or starting construction.

Frequently asked questions

How deep should pea gravel go?
Shallower than you might expect for a walking surface, since depth makes it harder to walk on. Decorative beds and drainage layers have their own requirements driven by the function rather than by appearance.
Why does it seem to disappear?
It migrates into soft ground and spreads past unrestrained edges. A geotextile separator underneath and proper edging solve both, and are cheaper than repeatedly topping up.
Is pea gravel good for drainage?
Very, because rounded uniform stone has large open voids. That is why it is used around perforated drainage pipe, where free flow matters more than load-bearing capacity.
