Lattice Polygon Area from Point Counts

How to use this tool

1. Enter interior lattice points, boundary lattice points.
2. Use the displayed units and confirm the model assumptions.
3. Calculate and compare the outputs against your input scenario.

Try this example

{
  "i": 12,
  "b": 10
}

Accuracy and scope

Pick theorem applies to a simple polygon with integer-grid vertices and no holes. Counts must include every boundary lattice point.
