Use dimensions
Choose Dimensions when you know the length, width and depth of a rectangular area such as a driveway, path, base or garden project.

Gravel Calculator
Estimate how much gravel you need in cubic yards or cubic meters, convert it to tons or tonnes, and calculate an optional project cost. Start with dimensions, a known area, or a known volume.

How the gravel calculation works
MEASSIVO calculates a base volume from your dimensions, area and depth, or from a volume you already know. It then applies your extra-material allowance and converts the result into volume, estimated weight and optional cost.
Volume = Length × Width × Depth
GRAVEL PLANNING GUIDE
How much gravel do I need?
The amount of gravel you need depends on the surface area, the planned depth and the bulk density of the material. This calculator keeps those parts separate so you can use the measurements you already have instead of forcing every project into the same input method.
Use a known area
Choose Area when you already know the square footage or square meters. Enter the area and the required depth to calculate the base volume.
Use a known volume
Choose Volume when you already have a cubic-yard or cubic-meter figure and mainly want to estimate weight, extra material and cost.
Understanding your gravel estimate
Cubic yards and cubic meters
Volume tells you how much space the gravel occupies. US projects commonly use cubic yards, while metric projects use cubic meters. MEASSIVO displays both so you can compare supplier information without doing a separate conversion.
Gravel weight and density
Weight is estimated from volume and bulk density. Gravel density varies with stone type, grading, moisture and compaction, so the material presets are planning values. If your supplier provides a density, enter that value as a custom density for a more project-specific estimate.
Extra material allowance
The extra-material field adds a percentage on top of the base volume. Use it to account for project conditions such as uneven grading, settlement, compaction or a small ordering margin. You can set the percentage to zero when you only want the calculated base quantity.
Estimated gravel cost
Enter a price per US ton or metric tonne to estimate material cost. The result covers the gravel quantity only; delivery, minimum-order charges, taxes, labor and equipment are not included unless they are already built into the price you enter.
Example: a 40 ft × 18 ft gravel area
A rectangular area measuring 40 ft by 18 ft has an area of 720 ft². At a depth of 4 in, the base volume is about 8.89 yd³. With a 10% extra-material allowance, the required volume becomes about 9.78 yd³. The weight then depends on the density selected for the gravel.
Calculator results are planning estimates. Confirm material density, delivery units and ordering requirements with your supplier before purchasing.
