Stone, Gravel & Driveway Calculators

Estimate material quantities for a particular driveway, drainage or landscape project. Identify the material first, then choose the right calculator for its volume and ordering assumptions.

Which calculator should I use?

Use the product specified for your project. A calculator measures quantities; it does not select a safe driveway or drainage design.

Project	Calculator	Estimates	Check first
Crushed limestone driveway or path	Crushed Limestone Calculator	Layer volume, approximate weight	Verify limestone grade, depth and product-specific bulk density.
Crusher run base course	Crusher Run Calculator	Finished volume and supplier order quantity	Verify grading, density state and any loose-to-finished factor.
Recycled asphalt millings driveway	Asphalt Millings Calculator	Finished layer and delivery quantities	Confirm reclaimed material, compacted density and delivery basis.
Drainage trench or rock bed	Drain Rock Calculator	Rock-filled volume and approximate weight	Confirm clean aggregate grading, pipe suitability and gravel-filled depth.
Specified stone dust or fines layer	Stone Dust Calculator	Volume, weight or bag quantity	Confirm the fines product is appropriate; do not assume it is bedding sand.

Understand material differences

Supplier terminology and grading affect which calculator and ordering assumptions are appropriate.

Crushed limestone vs. crusher run

Crushed limestone names the source rock; crusher run is typically a dense blend of graded stone and fines and need not be limestone. Confirm the exact product.

Read the crusher run guide

Drain rock vs. dense-graded base

Drain rock is selected for water movement and system compatibility. Dense-graded aggregate contains finer particles that can reduce open flow space.

Understand drainage rock

Asphalt millings vs. stone aggregate

Reclaimed asphalt pavement contains recovered asphalt-bound material. It is not new hot-mix asphalt or a substitute for every crushed-stone layer.

Loose versus compacted millings

Stone dust vs. bedding sand

Crushed-rock fines are not automatically suitable bedding sand for interlocking concrete pavers. Follow the applicable system and manufacturer specification.

Compare bedding materials

Plan a material order in seven steps

Record how you reached a quantity estimate before asking a supplier to convert it to a purchase order.

Identify the project. Decide whether you need a driveway surface, compacted base, drainage aggregate or other specified material.
Check the specification. Confirm product grade, fines, suitability and installation requirements.
Measure dimensions. Record area, length, width and actual material-filled depth.
Open the relevant calculator. Choose the tool matched to your material.
Confirm density. Use compatible units and distinguish loose from compacted states.
Review allowances. Consider losses, pipe deductions, compaction and order rounding only when justified.
Confirm with the supplier. Check selling unit, minimums, delivery fees and access.

There is no universal tons-per-cubic-yard conversion or compaction percentage for every stone material. US short tons and cubic yards are not equivalent units.

Questions before you calculate

Which calculator should I use for a gravel driveway?

First identify the supplier's actual surface or base product. Crushed limestone, crusher run and asphalt millings have different specifications. Compare the tools by material, then open the one that matches.

How do I calculate cubic yards?

For a rectangular layer, multiply length × width × depth in feet to get cubic feet, then divide by 27. Split irregular areas into measurable sections. Use the matching calculator for the complete material estimate.

Why does tons per cubic yard vary?

Bulk density depends on grading, voids, moisture and measurement state. Use a supplier figure compatible with loose delivery or finished compacted conditions rather than a universal number.

Are crusher run and drain rock interchangeable?

No automatic substitution is justified. Dense-graded crusher run generally contains fines, whereas an appropriate drainage aggregate may need open grading and a compatible filter.

How do I estimate an amount to order?

Start with geometric volume, then use a material-specific density or documented loose-volume factor if needed. Confirm supplier rounding, minimum orders, delivery charges and unloading arrangements.
