Gravel driveway
Start with the Gravel Calculatorfor a single quantity, use theDriveway Planner for sub-base, base, surface and truckloads, then organize the wider job inProject Builder.
MetricSketch TOOLS
From one measurement to a complete project plan.
Choose a focused calculator when you need a fast answer, or use Project Builder when the job needs geometry, materials, costs and project output in one connected workspace.
PROJECT PLANNING
Build the whole project.
Best when you need more than a quantity: lay out the project, organize elements and turn the result into something you can review or share.

- Best when the job needs geometry, materials and cost planning together.
- Work in one connected workspace instead of jumping between separate estimates.
- Review the project visually before you buy or build.

Open calculatorCOMMON PLANNING PATHS
Move from a quantity to a complete plan.
Start with the calculation that answers the immediate question, then move into a specialized planner or Project Builder when the project needs more detail.
Paver patio or walkway
Use the Paver Calculator for pieces, pallets, base, bedding sand, joint sand and edging. Use theGravel Calculator when you need an independent aggregate quantity.
Concrete or asphalt paving
Choose the Concrete Calculatorfor slabs, footings and post holes, or theAsphalt Calculator for paved volume and tonnage. Continue inProject Builder when multiple elements belong to the same project.
NOT SURE WHERE TO START?
Start with Project Builder.
You can begin with a simple floor, then add walls, materials and costs as the project becomes more detailed.
