**Introduction:** The Diagonal Size Calculator provides a simple and efficient way to find the diagonal size of a display based on its width and height. Whether you’re dealing with a television, monitor, or any other screen, this calculator empowers users to obtain accurate measurements without the need for complex mathematical calculations.

**Formula:** The calculator relies on the Pythagorean theorem to calculate the diagonal size. In a right-angled triangle, the square of the hypotenuse (diagonal) is equal to the sum of the squares of the other two sides (width and height).

**How to Use:**

- Input the width of the display in inches.
- Input the height of the display in inches.
- Click the “Calculate” button.
- The result will display the diagonal size of the display in inches.

**Example:** Suppose you have a monitor with a width of 18 inches and a height of 12 inches. Using the Diagonal Size Calculator, you can quickly find that the diagonal size is approximately 21.60 inches.
