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 (Termcap), 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.
