1. What is Aspect Ratio?

The aspect ratio of an image describes the proportional relationship between its width and height. It's commonly expressed as two numbers separated by a colon (e.g., 16:9).

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• Width — Horizontal dimension in pixels
• Height — Vertical dimension in pixels

Explanation: The ratio is calculated by dividing the width by the height. Common ratios include 1:1 (square), 4:3 (standard TV), and 16:9 (widescreen).

3. Importance of Aspect Ratio

Details: Aspect ratio is crucial in photography, video production, and web design as it affects how images appear on different devices and screens.

4. Using the Calculator

Tips: Enter the width and height in pixels. Both values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What does a ratio of 1.7778 mean?
A: This is the decimal equivalent of 16:9, the standard widescreen aspect ratio.

Q2: How do I convert the decimal ratio to X:Y format?
A: Multiply the decimal by a common denominator (like 1000) and simplify the fraction (e.g., 1.333 × 3 = 4:3).

Q3: Why is aspect ratio important in web design?
A: It ensures images display correctly without distortion across different screen sizes and devices.

Q4: What's the difference between aspect ratio and resolution?
A: Resolution is the total pixel count (e.g., 1920×1080), while aspect ratio is the proportional relationship between width and height.

Q5: What are common aspect ratios in photography?
A: Common ratios include 3:2 (35mm film), 4:3 (compact cameras), and 16:9 (widescreen).
