Am I just looking the wrong place?

If you are using an ANSI terminal emulator: The standard technique is to send the escape sequence to move to an absurdly large row and column position (<ESC>[999;999f) then query the cursor position (<ESC>[6n, which is responded to by <ESC>[{ROW};{COLUMN}R).

Telnet has command (NAWS) that reports changes in terminal sizes, but telnet commands are not available at the telnet stream level.

For Microsoft Windows console, I think in general you'd need native code.
