Gravel Calculator
Gravel — it computes volume as area × depth, converts to weight using the material density, and rounds up. This page runs that same calculation on your numbers, in your browser: no signup, no uploads, nothing stored.
Enter your length, width and depth and Gravel Calculator works out the volume and weight with area × depth and the material density — fast, free and private, with no sign-up or uploads.
Estimate only. Volume and weight depend on the area and depth you enter and on the material's density, moisture, settling and compaction, so round up when ordering.
About this calculator
Get gravel right and the rest of the task gets easier. It computes volume as area × depth, converts to weight using the material density, and rounds up. It matters before you buy: a clean volume estimate plus a waste allowance beats a guess every time. A path 10 m × 1 m × 0.05 m = 0.5 m³. At ~1.5 t/m³, that's about 0.75 tonnes of gravel. The tool above does the same computation in your browser — free, private, nothing stored.
How to use
- Enter the surface length in feet.
- Enter the surface width in feet.
- Enter the gravel depth in inches.
- Tap Calculate to see volume and the approximate tonnage.
Why use the Gravel Calculator
Instant
Every quantity is worked out on your device the moment you tap Calculate.
Private
The numbers you enter stay in your browser and are never uploaded or saved.
Free
No signup, no paywall, and no ads placed inside your results.
Works offline
Once the page has loaded it keeps working on a weak or dropped connection.
Mobile-first
Laid out for phones and tablets on site just as much as for desktops.
Planning estimates
Results are simplified planning estimates; real material needs vary by product size, waste, layout, local codes, and site conditions, so confirm before you buy or build.
Common uses
Use it when filling a bed or area to a depth
Use it for estimating soil, mulch or gravel volume
Use it when budgeting a landscaping job
Use it for outdoor and yard work
Use it when sizing a fill to an area and depth
Use it when reducing over-ordering
Technical notes
Gravel Calculator computes volume as area × depth, converts to weight using the material density, and rounds up.
A volume estimate from the dimensions you enter; allow for settling, compaction or spillage and round up when ordering.
Nothing you type is uploaded — the calculation happens entirely on your device.
Worked example
A path 10 m × 1 m × 0.05 m = 0.5 m³. At ~1.5 t/m³, that's about 0.75 tonnes of gravel.
FAQ
Is the gravel depth entered in inches?
Yes. Enter the gravel depth in inches; the tool turns it into feet before working out cubic feet.
Does the Gravel Calculator upload my area?
No. The Gravel Calculator runs in your browser and your figures are never sent to a server.
How is the gravel weight estimated?
Cubic yards are multiplied by about 1.4 tons, though the density varies by the type of gravel.
What depth suits a path?
A 2 to 4 inch layer is common for paths; heavier loads need a deeper, compacted base.
