1. What is Screen Diagonal?

The screen diagonal is the measurement of a screen's size from one corner to the opposite corner, typically measured in inches. It's the standard way to describe the size of TVs, monitors, and other display devices.

2. How Does the Calculator Work?

The calculator uses the Pythagorean theorem:

Where:

• \( \text{width} \) — Horizontal measurement of the screen (inches)
• \( \text{height} \) — Vertical measurement of the screen (inches)

Explanation: The diagonal forms the hypotenuse of a right triangle where the width and height are the other two sides.

3. Importance of Screen Size Calculation

Details: Knowing the exact diagonal size helps when comparing displays, determining viewing distance, and ensuring proper fit in installation spaces.

4. Using the Calculator

Tips: Enter the width and height in inches. Both values must be positive numbers. The calculator will compute the diagonal measurement.

5. Frequently Asked Questions (FAQ)

Q1: Why is screen size measured diagonally?
A: Diagonal measurement became standard because it provides a single number that accounts for both width and height, making size comparisons easier.

Q2: Does this work for curved screens?
A: For curved screens, this gives the "flat" diagonal measurement - the actual viewing surface along the curve would be slightly longer.

Q3: How accurate is this calculation?
A: The calculation is mathematically precise for flat rectangular screens when exact width and height are known.

Q4: Can I use this for aspect ratio calculations?
A: While this gives diagonal size, aspect ratio is simply width divided by height (e.g., 16:9).

Q5: What about screen area?
A: Screen area is width × height, which is different from diagonal size. Both measurements are useful for different purposes.
