Hypotenuse Calculator: Find the Hypotenuse of a Right Triangle Instantly

Calculate Your Right Triangle's Hypotenuse

Enter the length of the first leg of the right triangle.
Enter the length of the second leg of the right triangle.

Instantly calculate the hypotenuse (side 'c') of any right-angle triangle using the Pythagorean theorem. Input the lengths of the two shorter sides ('a' and 'b') to get precise results for construction, carpentry, or academic needs.

Pythagorean Theorem Formula

The hypotenuse (denoted as c) in a right-angled triangle is the longest side, opposite the right angle. It is calculated using the Pythagorean theorem, which states that the square of the hypotenuse is equal to the sum of the squares of the other two sides (legs):

c = √(a² + b²)

  • c: The length of the hypotenuse.
  • a: The length of the first shorter side (leg).
  • b: The length of the second shorter side (leg).
