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) or as a decimal value.

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 simplified ratio by finding the greatest common divisor of the width and height values.

3. Importance of Aspect Ratio

Details: Aspect ratio is crucial in photography, video production, web design, and graphic design. It affects how images are displayed on different devices and maintains proper proportions when resizing images.

4. Using the Calculator

Tips: Enter the width and height of your image in pixels. Both values must be positive integers. The calculator will display the aspect ratio as a decimal value and in simplified ratio format.

5. Frequently Asked Questions (FAQ)

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

Q2: Why is aspect ratio important in web design?
A: Aspect ratio ensures images maintain their proportions across different screen sizes and devices, preventing distortion.

Q3: How do I maintain aspect ratio when resizing images?
A: When resizing, lock the aspect ratio to prevent distortion. Most image editing software has this option.

Q4: Can aspect ratio affect image quality?
A: Yes, changing aspect ratio without proper cropping can lead to stretched or squashed images, reducing quality.

Q5: 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).
