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:

Where:

• \( Width \) — Width in pixels
• \( Height \) — Height in pixels
• \( Ratio \) — Aspect ratio (unitless)

Explanation: The calculator divides the width by the height to get the decimal aspect ratio, then simplifies the ratio to its lowest terms.

3. Importance of Aspect Ratio

Details: Aspect ratio is crucial in photography, video production, web design, and display technology. It determines how content is displayed and affects composition, scaling, and compatibility across different devices.

4. Using the Calculator

Tips: Enter width and height in pixels. Both values must be positive integers. The calculator will provide both decimal and simplified ratio formats.

5. Frequently Asked Questions (FAQ)

Q1: What are common aspect ratios?
A: Common ratios include 16:9 (widescreen), 4:3 (standard), 1:1 (square), 21:9 (ultrawide), and 3:2 (photography).

Q2: Why is aspect ratio important in web design?
A: It ensures images and videos display correctly across different screen sizes and maintains visual consistency.

Q3: How do I choose the right aspect ratio?
A: Consider your display device, content type, and intended use. Widescreen (16:9) is standard for videos, while 4:3 works well for presentations.

Q4: Can aspect ratio affect image quality?
A: Yes, using the wrong aspect ratio can cause stretching, cropping, or black bars, reducing visual quality.

Q5: What's the difference between pixel dimensions and aspect ratio?
A: Pixel dimensions specify exact width and height, while aspect ratio describes the proportional relationship between them.
