Perimeter of a Polygon Calculator: Find Any N-gon Perimeter

Calculate the Perimeter of Your Polygon

Separate each side length with a comma (e.g., 5, 7, 3 for a triangle).

Easily find the perimeter of any polygon, from a simple triangle to complex n-gons. Our online Perimeter of a Polygon Calculator streamlines geometry calculations, providing accurate results instantly. Just input the lengths of each side and get your answer. Perfect for homework, design, or quick reference.

Formula:

The perimeter (P) of any polygon is the sum of the lengths of its sides.

Formula: P = s1 + s2 + s3 + ... + sn

  • P = Perimeter
  • s1, s2, ..., sn = Lengths of the individual sides of the polygon
