The Pick's Theorem calculator provides the approximate area of a polygon based on the number of lattice points inside the polygon, the number of points on the boundary and the size of a lattice square.

INSTRUCTIONS: Choose units and enter the following:

  • (i) Interior Lattice Points
  • (b) Boundary Lattice Points
  • (LSA) Area of Lattice Square

Pick's Theorem Area (A): The calculator returns the area in square meters.  However, this can be automatically converted to compatible units via the pull-down menu.

A=i+b/2-1=10

Pick's Theorem provides a simple formula for calculating the area A of a simple polygon constructed on a grid of equal-distanced points such that all the polygon's vertices are grid points. The following formula is used: A=i+b2-1A=i+b21, where:

  • ii = lattice points in the interior
  • bb = lattice points on the boundary
