Measure the area and specified layer thickness, or convert a known cubic-yard quantity into tons.
Enter #57 layer depth.
Override supplier density when known.
What each input means
Starting measurement
Choose project area or known cubic yards.
Use known cubic yards from plans or area/depth from measurements.Project area
Surface area covered by #57 stone.
Unit: sq ft or m2. Measure or calculate total square feet.Known volume
Known cubic yards of #57 stone.
Unit: cu yd. Enter plan or supplier volume directly.Stone depth
Finished #57 stone layer thickness.
Unit: in or cm. Measure the specified layer depth.Supplier density
Editable #57 stone bulk density.
Unit: lb/ft3 or kg/m3. Replace the default with supplier tons per yard or density.Compaction allowance
Small allowance for settlement or placement.
Unit: percent. Set to 0 for loose drainage placement if appropriate.Extra / waste
Percent added for cuts, spillage, edge cleanup, and small estimating errors.
Unit: percent. Use 5 percent for simple square work and 10 percent or more for irregular work.Price per ton
Optional supplier price used to estimate material cost before delivery fees and taxes.
Unit: USD per US ton. Enter the quoted material price per US short ton. Leave 0 if you only need quantity.Check the calculation
Example: 200 sq ft at 4 inches deep equals about 2.47 cubic yards before allowances.
A 20 × 10 ft area at 4 inches deep contains 2.47 compacted cubic yards before allowances.
Total loose order 2.86 cu yd Total weight 3.86 US tons
Volume = area x depth, or use known cubic yards. Weight = volume x density.
Assumptions to check
- The calculator uses 100 lb/ft³ as a planning density.
- Regional #57 gradations and weights vary.
- Confirm whether your supplier sells by ton or cubic yard.
- Does not verify gradation compliance.
- Does not design drainage systems.
- Washed and unwashed products can behave differently.

Frequently Asked Questions
What does this #57 stone calculator calculate?
It uses project-specific inputs and the formula shown below. Volume = area x depth, or use known cubic yards. Weight = volume x density.
Are the presets exact specifications?
No. Presets are editable planning starting points. Confirm depths, materials, and densities with the supplier, manufacturer, or project designer.
Why can delivered weight differ?
Bulk density varies by supplier and moisture level. Moisture, gradation, compaction, and scale accuracy can change the delivered weight.
