Why Programmers Should Use Portrait Mode Screens

Assume you have 1680x1050 (WSXGA+) monitor.

Window border + Menu bar + Tool Bars = 175px (vertical)
Status Bar + Horizontal Scroll Bar   =  55px
Total                                = 230px

Landscape Mode Active code area      = 1050px - 230px
                                     =  820px

Portrait  Mode Active code area      = 1680px - 230px
                                     = 1450px

Ratio                                = 1450/820
                                     = 1.768

Vertical coding area gained          = (1450-820)*100%/820
                                     = 76.83%
