#57 Stone Calculator

Calculate #57 stone volume from your measurements, then add the product's bulk density from your supplier if you also need an estimated weight.

Units
Area and depth

Section 1

Shape

For a square, enter the same length and width.

Enter the finished depth you plan to use.

Add another area — a second bed or a path, for example — to calculate a combined total.

Advanced optionsExtra material / handling allowance

Adds the percentage you choose to the order volume for waste, handling or contingency. It is separate from compaction.

Result

Your result will appear here

Enter your measurements and calculate to see volume in cubic yards, cubic feet, and cubic metres.

How this calculator works

Measure each area, choose its shape and enter the finished depth. The calculator multiplies area by depth and converts the result to cubic yards, cubic feet and cubic metres.

Volume = Area × Finished depth

Area and depth must use compatible units. The calculator converts them for you.

About #57 stone

“#57” is a size designation for crushed stone. The rock type, exact grading and quarry vary from supplier to supplier, so two #57 products can differ.

One product figure is not a #57 standard

A weight-per-yard figure published for one #57 product applies to that product. It is not a national #57 density. For weight, ask your supplier for the bulk density of the product you are buying and whether it is loose or compacted.

Common uses

Comparing with other crushed stone? See the Crushed Stone Calculator. For other materials, use the Gravel Calculator.

Worked example

Example: drainage layer 50 ft × 2 ft at 6 in deep

  1. Area: 50 ft × 2 ft = 100 ft²
  2. Depth: 6 in = 0.5 ft
  3. Volume: 100 × 0.5 = 50.0 ft³
  4. Cubic yards: 50.0 ÷ 27 = 1.85 yd³

Result: 1.85 cubic yards (1.42 cubic metres). The depth is an example input.

Frequently asked questions

How much does a yard of #57 stone weigh?

It depends on the product — rock type, grading, moisture and whether it is loose or compacted. Enter your supplier’s bulk density to get an estimate.

Is #57 stone the same everywhere?

The size designation is shared, but the rock and exact grading depend on the quarry. Treat each supplier’s #57 as its own product.

Can I use this for a French drain?

For a trench with a pipe, use the French Drain Gravel Calculator — it subtracts the pipe’s volume when the pipe sits fully inside the gravel.
