# About This Calculator

The aspect ratio of an image or screen is the proportional relationship between its width and its height. It is commonly expressed as two numbers separated by a colon, such as $16:9$.

In the digital age, aspect ratios are critical for video production, web design, and photography to ensure content is displayed correctly without stretching or cropping. Common standards include: - **16:9**: Modern widescreen (TVs, Monitors). - **4:3**: Traditional television and old computer monitors. - **21:9**: Ultra-widescreen cinema format. - **1:1**: Square (common on social media like Instagram).

Our calculator uses the Greatest Common Divisor (GCD) algorithm to perfectly simplify any set of pixel dimensions into its most readable ratio format.

How To Use

  1. Enter the **Width** (e.g., in pixels or inches).
  2. Enter the **Height**.
  3. The simplified **Aspect Ratio** will appear instantly.
  4. Use the GCD step to understand how the ratio was derived.
