1. What is Image Diagonal?

The diagonal of an image is the straight-line distance from one corner of the image to the opposite corner. It's calculated using the Pythagorean theorem based on the image's width and height dimensions.

2. How Does the Calculator Work?

The calculator uses the Pythagorean theorem:

Where:

• \( width \) — Horizontal dimension in pixels
• \( height \) — Vertical dimension in pixels

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

3. Importance of Diagonal Calculation

Details: Knowing the diagonal dimension helps in comparing image sizes, determining aspect ratios, and understanding the actual size when displayed on screens with different pixel densities.

4. Using the Calculator

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

5. Frequently Asked Questions (FAQ)

Q1: Does this work for any rectangular image?
A: Yes, this formula works for any rectangular image regardless of its aspect ratio.

Q2: How is this different from screen size measurements?
A: Screen sizes are typically measured in inches diagonally, while this calculates the diagonal in pixels.

Q3: Can I use this for non-image dimensions?
A: Yes, this formula works for any right-angled triangle, not just images.

Q4: Does pixel density affect the result?
A: No, this calculation is purely based on pixel dimensions, not physical size or pixel density (PPI).

Q5: What about non-rectangular images?
A: This calculation only applies to rectangular images. For other shapes, different methods are needed.
