1. What is Screen Diagonal?

The screen diagonal is the measurement of a screen's size from one corner to the opposite corner. It's the standard way to describe screen sizes for TVs, monitors, and mobile devices.

2. How Does the Calculator Work?

The calculator uses the Pythagorean theorem:

\[ diagonal = \sqrt{width^2 + height^2} \]

Where:

Explanation: The formula calculates the hypotenuse of a right-angled triangle formed by the width and height of the screen.

3. Importance of Diagonal Measurement

Details: Screen diagonal is the standard measurement used to compare display sizes across different devices and aspect ratios.

4. Using the Calculator

Tips: Enter width and height in the same units (inches, centimeters, etc.). Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Why is screen size measured diagonally?
A: Diagonal measurement provides a single number that represents screen size regardless of aspect ratio, making comparisons easier.

Q2: Does aspect ratio affect the diagonal measurement?
A: No, the diagonal is independent of aspect ratio. Two screens with the same diagonal can have different widths and heights.

Q3: What units should I use?
A: Any consistent units can be used (inches, cm, etc.). The result will be in the same units as your input.

Q4: How accurate is this calculation?
A: The calculation is mathematically precise. Any inaccuracy would come from imprecise width/height measurements.

Q5: Can I use this for non-rectangular screens?
A: No, this calculator is designed for standard rectangular displays. Curved or non-rectangular screens require different calculations.
