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.
