1. What is Aspect Ratio?

The aspect ratio of an image is the proportional relationship between its width and height. It's expressed as two numbers separated by a colon (e.g., 16:9) or as a single decimal value (e.g., 1.777).

2. How Does the Calculator Work?

The calculator uses the aspect ratio formula:

Where:

• \( width \) — Image width in pixels
• \( height \) — Image height in pixels

Explanation: The calculator also provides the reduced form of the ratio by dividing both dimensions by their greatest common divisor (GCD).

3. Importance of Aspect Ratio

Details: Aspect ratio is crucial in photography, videography, web design, and print media as it determines how images will be displayed and cropped across different devices and mediums.

4. Using the Calculator

Tips: Enter the width and height of your image in pixels. Both values must be positive numbers. The calculator will provide both the decimal aspect ratio and the simplified ratio.

5. Frequently Asked Questions (FAQ)

Q1: What are common aspect ratios?
A: Common ratios include 1:1 (square), 4:3 (standard TV), 16:9 (HD video), and 3:2 (35mm film).

Q2: How does aspect ratio affect image quality?
A: Using the wrong aspect ratio can lead to stretching, cropping, or letterboxing of images, affecting composition and quality.

Q3: Can I calculate aspect ratio from physical dimensions?
A: Yes, aspect ratio can be calculated from any consistent units (inches, cm, etc.), but pixels are most common for digital images.

Q4: What's the difference between aspect ratio and resolution?
A: Resolution is the total number of pixels (width × height), while aspect ratio is the proportional relationship between width and height.

Q5: How do I maintain aspect ratio when resizing?
A: When resizing, lock the aspect ratio to prevent distortion, then adjust either width or height while the other dimension changes proportionally.
