This calculator returns bulk gravel volume and tons from area, compacted depth and an editable density. Formula LAND-GRAVEL-001 v1.0.0. Fabric and edging stay off this tonnage line. Add the tons to an estimate. It is not a pavement section or a live quarry quote.
- Measure the finished gravel length, average width and compacted installed depth.
- Enter the supplier's density in tons per cubic yard for the selected material.
- Use the rounded volume and estimated weight as a starting point for a supplier quote and delivery discussion.
Size chart
Gravel pad chart (planning density 1.35 t/yd³)
Replace density with the quarry ticket. Decorative stone and compacted base do not share a density.
| Pad | Primary | Check |
|---|---|---|
| 10 × 10 ft × 3 in | 1.1 yd³ | 25 ft³ |
| 12 × 20 ft × 4 in | 3.3 yd³ | 80 ft³ |
| 20 × 20 ft × 4 in | 5.5 yd³ | 133.33 ft³ |
| 50 × 12 ft × 4 in | 8.2 yd³ | 200 ft³ |
Metric example — 15 × 4 m at 100 mm. A 15 × 4 m pad at 100 mm compacted depth, density 1.35 t/yd³ and 10% waste, returns 8.7 yd³. Replace density with the quarry ticket.
Bags vs bulk. Tons versus a leftover tenth: quarries sell delivery increments. A short driveway costs more than leftover stone.
- Density chart. Volume × bulk density ≈ tons. Density varies by rock, moisture and compaction. Replace 1.35 with the quarry ticket. Engineering ToolBox — bulk density of common materials
Add your project costs
Enter supplier prices and any labour, equipment or delivery costs. Pick a currency — badges, inputs, and totals follow.
Costs use the bulk-yard, bag or truck-load rate you type. Construclytic does not fetch quarry or nursery prices. Delivery, fabric and edging stay separate lines. For GCC projects, select QAR, AED, SAR, KWD, OMR or BHD and enter local supplier rates.
How this calculator works
A transparent gravel calculator takeoff.
Feroz SheikhWritten by Feroz Sheikh · founder
This calculator converts a rectangular gravel area and compacted depth into bulk volume, then applies a documented allowance before delivery rounding and density-based weight estimation.
Gravel uses area × depth × a density you can edit, then rounds to supplier tons. Construclytic does not pretend every region sells the same tons per yard.
Worked example. Example: a 12 ft × 10 ft area at 3 in depth holds about 1.11 yd³ before waste. With 10% allowance, the bulk order rounds to 1.3 yd³; at 1.35 tons/yd³, that is about 1.76 tons.
See the example inputs and calculated result
This separate example uses the calculator's starting values in imperial units. It stays unchanged when you edit the tool above. Example rates, yields and dimensions are assumptions, not recommendations for your project.
| Input | Example value |
|---|---|
| Area length | 12 ft |
| Area width | 10 ft |
| Installed depth | 3 in |
| Supplier density | 1.35 US tons / yd³ |
| Waste factor | 10 % |
Example result: Bulk gravel order — 1.3 yd³.
Area length × width × depth ÷ 27 × (1 + waste)
Use the labelled units above when reproducing this example. To work in metric, switch the calculator to Metric; applicable measurements are converted, while product-specific units remain labelled.
- 1. Measure the finished gravel length, average width and compacted installed depth.
- 2. Enter the supplier's density in tons per cubic yard for the selected material.
- 3. Use the rounded volume and estimated weight as a starting point for a supplier quote and delivery discussion.
Field notes that change the number
- Compacted base and loose decorative stone are different densities. Change the input.
- Driveway base often wants a compacted depth; decorative beds often do not.
- Delivery minimums and truck size still sit with the quarry, not this page.
Common mistakes
- Using a landscape-bed density for a compacted road base.
- Ordering by area and ignoring depth.
- Treating tons as cubic yards one-for-one.

Questions
Questions about gravel calculator
Why does gravel weight vary?
Weight changes with material type, moisture, compaction and source. Confirm the supplier's current density before ordering.
Does this design a base course?
No. Confirm depth, drainage, geotextile, compaction and local project requirements independently.
How much gravel for a 50x12 driveway?
A 50 × 12 ft run at 4 in compacted depth, density 1.35 t/yd³ and 10% waste, returns 8.2 yd³. Replace density with the quarry ticket.
Is density the same for every stone?
No. Decorative stone and compacted base do not share a density. Enter the number on the ticket.
What is the formula ID?
This gravel calculator publishes formula LAND-GRAVEL-001, version 1.0.0. The ID stays on the result and on the estimate line.
