Ho cercato e trovato una soluzione per Windows su:
http://code.activestate.com/recipes/440694-determine-size-of-console-window-on-windows/
e una soluzione per Linux qui.
Quindi ecco una versione che funziona sia su Linux, OS X sia su Windows / Cygwin:
""" getTerminalSize()
- get width and height of console
- works on linux,os x,windows,cygwin(windows)
"""
__all__=['getTerminalSize']
def getTerminalSize():

current_os = platform.system()
tuple_xy=None
if current_os == 'Windows':
tuple_xy = _getTerminalSize_windows()
if tuple_xy is None:
tuple_xy = _getTerminalSize_tput()
# needed for window's python in cygwin's xterm!
if current_os == 'Linux' or current_os == 'Darwin' or current_os.startswith('CYGWIN'):
tuple_xy = _getTerminalSize_linux()
if tuple_xy is None:
print "default"
tuple_xy = (80, 25) # default value
return tuple_xy
