1. What is Aspect Ratio?

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

2. How Does the Calculator Work?

The calculator uses the aspect ratio formula:

Where:

• Width — The horizontal dimension in pixels
• Height — The vertical dimension in pixels

Explanation: The calculator also provides the simplified ratio by dividing both dimensions by their greatest common divisor.

3. Importance of Aspect Ratio

Details: Aspect ratio is crucial for responsive design, ensuring images and videos display correctly across different devices without distortion. It's particularly important for background images in Bootstrap websites where maintaining proportions is essential.

4. Using the Calculator

Tips: Enter the width and height in pixels (must be positive integers). The calculator will provide both the decimal value and simplified ratio (like 16:9).

5. Frequently Asked Questions (FAQ)

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

Q2: Why is aspect ratio important for Bootstrap?
A: Bootstrap uses aspect ratios to maintain responsive containers that scale properly across devices.

Q3: How do I use aspect ratio for background images?
A: Calculate the image's aspect ratio, then use CSS padding-top with percentage equal to (height/width)*100 to maintain proportions.

Q4: What's the difference between display and pixel aspect ratio?
A: This calculator computes pixel aspect ratio. Display aspect ratio refers to physical screen dimensions.

Q5: How do I maintain aspect ratio when resizing?
A: Multiply one dimension by the aspect ratio to calculate the other dimension proportionally.
