Use stringwidth to find the width of the strings using a convenient font 
size. Divide the media size in 2, use the string width to calculate what 
scale factor is required to fit the string into that width. Use the 
scale operator to scale the drawing operations using that scale factor.

You can, of course, use the previous answers for charpath/pathbbox to 
get both the width and height of the text and use that to calculate 
scaling in each direction independently.

Of coruse, the full stop might end up being huge, but then what did you 
want ? Its not completely clear to me what you want to do.
