1. What is Aspect Ratio?

The aspect ratio of an image or screen is the proportional relationship between its width and height. It's expressed as two numbers separated by a colon (e.g., 16:9). Aspect ratios are fundamental in photography, video, and display technologies.

2. How Does the Calculator Work?

The calculator uses the aspect ratio formula:

\[ \text{Ratio} = \frac{\text{width}}{\text{height}} \]

Where:

\( \text{width} \) — The horizontal dimension in pixels
\( \text{height} \) — The vertical dimension in pixels

Explanation: The calculator also provides the simplified ratio by dividing both dimensions by their greatest common divisor.

3. Common Aspect Ratios

Details: Common aspect ratios include 1:1 (square), 4:3 (standard TV), 16:9 (HDTV), 16:10 (computer monitors), and 21:9 (ultrawide displays).

4. Using the Calculator

Tips: Enter width and height in pixels (must be positive numbers). The calculator will provide both the decimal ratio and simplified ratio.

5. Frequently Asked Questions (FAQ)

Q1: Why is aspect ratio important?
A: Aspect ratio determines how content fits on screens and affects composition in photography/videography.

Q2: What's the difference between 16:9 and 4:3?
A: 16:9 is wider (more rectangular) while 4:3 is more square. 16:9 is standard for HDTV and most online video.

Q3: How do I maintain aspect ratio when resizing?
A: Scale both dimensions by the same percentage or use aspect ratio constraints in editing software.

Q4: What's the aspect ratio of a square?
A: 1:1 - width and height are equal.

Q5: Can aspect ratio affect image quality?
A: Yes, stretching an image to a different aspect ratio can cause distortion and quality loss.
