A Length of Hypotenuse Calculator is a simple yet powerful geometry tool that helps determine the length of the hypotenuse in a right-angled triangle. The hypotenuse is the longest side of a right triangle and is always opposite the 90-degree angle. This calculator uses the well-known Pythagorean Theorem to calculate the missing side accurately and instantly.
Whether you are a student solving geometry homework, a teacher preparing classroom examples, an engineer working on structural designs, or a carpenter measuring building components, calculating the hypotenuse is a common mathematical task. Instead of performing manual calculations, our calculator provides quick and reliable results with just two input values.
The Length of Hypotenuse Calculator is designed for ease of use and delivers precise answers in seconds. It is suitable for educational, professional, and everyday applications where right-triangle measurements are required.
What Is a Length Of Hypotenuse Calculator?
A Length of Hypotenuse Calculator is an online mathematical tool that calculates the longest side of a right triangle when the lengths of the other two sides (known as the legs) are provided.
The calculator is based on the Pythagorean Theorem, one of the most fundamental principles in geometry. This theorem states that the square of the hypotenuse is equal to the sum of the squares of the other two sides.
This calculator eliminates manual calculations and reduces the possibility of errors, making it ideal for both learning and practical work.
Formula Used
The calculator uses the Pythagorean Theorem:
Hypotenuse = √(a² + b²)
Where:
- a = Length of the first side
- b = Length of the second side
- √ = Square root
- Hypotenuse = Longest side of the triangle
This formula is universally accepted and is used in mathematics, engineering, architecture, construction, and physics.
Required Inputs
The calculator requires only two essential inputs:
- Length of Side A
- Length of Side B
Both values must represent the two sides that form the right angle.
Output
After calculation, the calculator displays:
- Length of the Hypotenuse
- Accurate Result
- Calculated Triangle Side
The result is presented using the same unit of measurement entered by the user, such as centimeters, meters, inches, or feet.

Practical Example 1
Given:
- Side A = 3
- Side B = 4
Calculation:
Hypotenuse = √(3² + 4²)
Hypotenuse = √(9 + 16)
Hypotenuse = √25
Result:
5
Practical Example 2
Given:
- Side A = 8
- Side B = 15
Calculation:
Hypotenuse = √(8² + 15²)
Hypotenuse = √(64 + 225)
Hypotenuse = √289
Result:
17
Practical Example 3
Given:
- Side A = 12
- Side B = 16
Calculation:
Hypotenuse = √(12² + 16²)
Hypotenuse = √(144 + 256)
Hypotenuse = √400
Result:
20
