1. What is Aspect Ratio?

Aspect ratio is the proportional relationship between the width and height of an image or screen. It is expressed as two numbers separated by a colon (e.g., 16:9), representing width and height respectively.

2. How Does the Calculator Work?

The calculator uses the greatest common divisor (GCD) to simplify the ratio:

\[ \text{Aspect Ratio} = \frac{\text{Width}}{\text{GCD(Width, Height)}} : \frac{\text{Height}}{\text{GCD(Width, Height)}} \]

Where:

Width — Horizontal resolution in pixels
Height — Vertical resolution in pixels
GCD — Greatest Common Divisor of width and height

Explanation: The calculator finds the largest number that divides both width and height evenly, then divides both dimensions by this number to get the simplified ratio.

3. Importance of Aspect Ratio

Details: Aspect ratio is crucial in photography, videography, web design, and display technology. It determines how content is framed and displayed, affecting composition, compatibility, and viewing experience across different devices.

4. Using the Calculator

Tips: Enter the width and height in pixels (must be positive integers). The calculator will automatically compute and display the simplified aspect ratio.

5. Frequently Asked Questions (FAQ)

Q1: What are common aspect ratios?
A: Common ratios include 4:3 (standard definition), 16:9 (HD and Full HD), 16:10 (some computer monitors), and 21:9 (ultrawide displays).

Q2: How does aspect ratio affect image quality?
A: Aspect ratio doesn't directly affect quality but determines how content is framed. Mismatched ratios can cause letterboxing, pillarboxing, or image cropping.

Q3: Can I calculate aspect ratio for non-integer dimensions?
A: This calculator works with integer pixel values. For non-integer dimensions, you would need to convert to a common unit first.

Q4: Why simplify the ratio?
A: Simplifying makes ratios easier to understand, compare, and standardize across different resolutions and devices.

Q5: How is aspect ratio different from resolution?
A: Resolution specifies the number of pixels (e.g., 1920×1080), while aspect ratio describes the proportional relationship between width and height (16:9 in this case).
