1. What Is Aspect Ratio?

Aspect ratio is the proportional relationship between the width and height of a display. It's expressed as two numbers separated by a colon (e.g., 16:9), representing width relative to height.

2. How Does The Calculator Work?

The calculator uses the greatest common divisor (GCD) algorithm:

Where:

• Width — Screen width in pixels
• Height — Screen height in pixels
• GCD — Greatest Common Divisor of width and height

Explanation: The calculator simplifies the width:height ratio to its simplest form using the GCD algorithm.

3. Common Aspect Ratios

Common Ratios: 4:3 (standard definition), 16:9 (HD and Full HD), 16:10 (some computer monitors), 21:9 (ultrawide displays), and 1:1 (square format).

4. Using The Calculator

Tips: Enter the screen width and height in pixels. The calculator will determine the aspect ratio and the decimal ratio value.

5. Frequently Asked Questions (FAQ)

Q1: Why is aspect ratio important?
A: Aspect ratio affects how content is displayed on screens, influencing everything from video playback to website design and gaming experiences.

Q2: What's the difference between aspect ratio and resolution?
A: Resolution refers to the number of pixels (e.g., 1920×1080), while aspect ratio describes the proportional relationship between width and height.

Q3: Can different resolutions have the same aspect ratio?
A: Yes, for example, 1280×720, 1920×1080, and 3840×2160 all have a 16:9 aspect ratio.

Q4: What is the most common aspect ratio for modern displays?
A: 16:9 is currently the most common aspect ratio for TVs, computer monitors, and smartphones.

Q5: How does aspect ratio affect content creation?
A: Content creators need to consider aspect ratio to ensure their work displays properly on different devices without cropping or distortion.
