I think the way to determine the width of the current terminal is
terminal-dependent.  You could use curses.

If memory serves, when a window gets resized the process(es?)
associated with it gets sent a WINCH signal.  I don't know whether
curses traps this for you; if so, just keep rechecking the
terminal width via curses at appropriate moments.
