How many tons of #57 stone are in a cubic yard?

Data checked October 2026

Short answer

A cubic yard of #57 stone weighs about 1.35 tons (2,700 lb) loose, as it comes off the truck — published factors run 1.3–1.65 tons.

Where the number comes from: Martin Marietta 1.32, Vulcan 1.30, Mulch Pros scale 1.35; Kokosing (OH) uses 1.65.
One ton is 0.74 cu yd (20 cu ft) and covers about 120 sq ft at 2 in, 80 at 3 in or 60 at 4 in.
In bags: 54 bags of 0.5 cu ft make a cubic yard; each weighs about 50 lb.
#57 stone is clean stone — it settles slightly but does not compact by volume like base gravel.
A single-axle dump truck (about 5 tons) carries roughly 3.7 cu yd; a tandem (up to 18 tons) about 13.3 cu yd.
Price check: $35–$55/ton national (American Rock Supply 2026); $58.95/ton at a GA yard; $72.65+/yd in NE Ohio. At the default $45.00/ton that is about $60.75 per cubic yard.

What's it for?

Project

Decorative gravel needs at least 2 in to hide fabric (Stone Center); larger rock looks best at 3 in or more (Roseville suggests 3–6 in).

How this was worked out

Weight converts yards to tons: tons = cubic yards × 1.35. A cubic yard is 27 cubic feet; spread 1 in deep it covers 324 sq ft, so coverage at any depth is 324 ÷ inches, and per ton it is 324 ÷ (inches × 1.35).

Quarry tables disagree because stone type, gradation and moisture change the weight, and because some list compacted rather than loose weights — Martin Marietta's "base" figures (1.90–1.95 t) are compacted-in-place values. If your yard prints a factor on its ticket or website, enter it in the calculator; it beats any average.

Short answer

A cubic yard of #57 stone weighs about 1.35 tons (2,700 lb) loose, as it comes off the truck — published factors run 1.3–1.65 tons.

Where the number comes from: Martin Marietta 1.32, Vulcan 1.30, Mulch Pros scale 1.35; Kokosing (OH) uses 1.65.

One ton is 0.74 cu yd (20 cu ft) and covers about 120 sq ft at 2 in, 80 at 3 in or 60 at 4 in.

In bags: 54 bags of 0.5 cu ft make a cubic yard; each weighs about 50 lb.

#57 stone is clean stone — it settles slightly but does not compact by volume like base gravel.

A single-axle dump truck (about 5 tons) carries roughly 3.7 cu yd; a tandem (up to 18 tons) about 13.3 cu yd.

Price check: $35–$55/ton national (American Rock Supply 2026); $58.95/ton at a GA yard; $72.65+/yd in NE Ohio. At the default $45.00/ton that is about $60.75 per cubic yard.
