Formula and method
This calculator computes Decimal ratio, Total pixels directly in your browser without sending data to an external server.
Mathematical formula
- Decimal ratio:
width ÷ height - Total pixels:
width × height ÷ 1000000
Variables and parameters
- Width (width): default value 1920 px.
- Height (height): default value 1080 px.
Some formulas are undefined for certain input combinations (such as division by zero or logarithms of non-positive numbers). In those cases the live tool displays an alert instead of NaN.
Examples
- Example: with Width = 1920 px, Height = 1080 px, this calculator returns Decimal ratio = 1.7778 :1, Total pixels = 2.07 MP.
Aspect Ratios in Web & Video Production
Aspect ratio defines the proportional ratio between width and height ($W:H$), regardless of physical screen size or resolution pixel counts. Common ratios include 16:9 for widescreen video, 4:3 for classic displays, and 1:1 or 9:16 for social media formats.
When scaling responsive images or web video embeds, maintaining fixed aspect ratios via CSS `aspect-ratio` or padding tricks prevents Layout Shift (CLS) errors in Web Vitals audits.
