screen: Window Size

 
 11.10 Window Size
 =================
 
  -- Command: width ['-w'|'-d'] [cols [lines]]
      ('C-a W')
      Toggle the window width between 80 and 132 columns, or set it to
      COLS columns if an argument is specified.  This requires a capable
      terminal and the termcap entries 'Z0' and 'Z1'.  See the 'termcap'
      command (SeeTermcap), for more information.  You can also
      specify a height if you want to change both values.  The '-w'
      option tells screen to leave the display size unchanged and just
      set the window size, '-d' vice versa.
 
  -- Command: height ['-w'|'-d'] [lines [cols]]
      (none)
      Set the display height to a specified number of lines.  When no
      argument is given it toggles between 24 and 42 lines display.
