Our free online Height of a Triangle Calculator quickly determines the altitude of any triangle. Whether you have the base and area or all three side lengths, this tool simplifies complex geometry calculations. Ideal for students, educators, and professionals needing precise triangle height measurements for various applications.

Formula:

The fundamental formula for calculating the height (h) of a triangle is based on its area and base length:

h = 2 × Area / b

Where:

  • h = The height (altitude) of the triangle.
  • Area = The total area enclosed by the triangle.
  • b = The length of the base corresponding to the height h.
