You could make a program which does what "resize" does to find the
screensize: it moves the cursor and asks where it is. (I'm not
aware of an existing program which asks based on tab stops).

The control sequence that does the asking is the cursor position
report (CPR).

(also vt100.net).
Not all terminals implement this (for instance FreeBSD console probably
does not).
