For the mode line, you can diddle the font size etc by customizing the variables mode-line and mode-line-inactive.  Dunno about the echo area.
Hope this helps.
Cheers.

Hi list members,

I have been looking around for a way to resize the text displayed in the
echo area. I found that for the buffer, C-x + and C-x - does the sizing
for the buffer alright, but I haven't found how to do this for the echo
area / mode line?

Ideally, if there is a clever way to automatically increase the default
text size in the echo area and buffer when changing input mode (to
chinese-tonpy)?

Thanks!
