Look at the documentation for the WIDTH keyword in XYOUTS.
To make sure e.g., that a text is shorter than the width of
a window, something like this should do:
DEVICE,GET_GRAPHICS_FUNCTION=OLDGRAPH
DEVICE,SET_GRAPHICS_FUNCTION=5 ; GXnoop --
xyouts,0.,0.,text,width=text_width,/normal
device,set_graphics_function=OLDGRAPH
xyouts,0.,0.,text,charsize=1./width ;; Adjust charsize to fit.

If you are happy using normalized coordinates, then the WIDTH
keyword to the xyouts procedure should give you the information
you seek. Check it out!
If you are happier using data coordinates, you may need to
use convert_coord as well.
