Formula and method
This calculator computes First screen area, Second screen area, Area increase directly in your browser without sending data to an external server.
Mathematical formula
- First screen area:
first² × ratioW × ratioH ÷ (ratioW × ratioW + ratioH × ratioH) - Second screen area:
second² × ratioW × ratioH ÷ (ratioW × ratioW + ratioH × ratioH) - Area increase:
(second²-first²) ÷ first² × 100
Variables and parameters
- First diagonal (first): default value 27 in.
- Second diagonal (second): default value 32 in.
- Aspect ratio width (ratioW): default value 16.
- Aspect ratio height (ratioH): default value 9.
