1. What is Aspect Ratio?

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

2. How Does the Calculator Work?

The calculator uses the aspect ratio formula:

\[ \text{Aspect Ratio} = \frac{\text{Width}}{\text{Height}} \]

Where:

Explanation: The calculator provides both the decimal aspect ratio and the simplified ratio format (e.g., 16:9).

3. Importance of Aspect Ratio

Details: Aspect ratio is crucial in photography, video production, web design, and display technology. It affects how content is displayed, cropped, and scaled across different devices and platforms.

4. Using the Calculator

Tips: Enter the width and height values in the same units (pixels, inches, etc.). Both values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What are common aspect ratios?
A: Common ratios include 4:3 (traditional TV), 16:9 (HDTV), 1:1 (square), and 21:9 (ultrawide).

Q2: How do I maintain aspect ratio when resizing?
A: Multiply the original height by the desired width divided by original width, or vice versa, to maintain proportions.

Q3: What's the difference between aspect ratio and resolution?
A: Aspect ratio describes the shape (width:height proportion), while resolution describes the number of pixels (e.g., 1920×1080).

Q4: Can aspect ratio affect image quality?
A: Yes, stretching or compressing an image to fit a different aspect ratio can distort it and reduce quality.

Q5: How do I calculate aspect ratio from resolution?
A: Divide the width by the height and simplify the fraction (e.g., 1920÷1080 = 16:9).
