That is indeed corect.  I used ghostscipt to create TIFF files using
the following two sets of options:

-sDEVICE=tiffg3 -r204x196 -sPAPERSIZE=letter

-sDEVICE=tiffg3 -r204x196 -sPAPERSIZE=a4

Using tiffinfo, both files were 1728 pixels in width, which works
out to the A4 dimension of 215 mm.  (The length of the letter page
was 11 inches though, but since most machines receive unlimited
page length this is not important.)

This is not a major issue, but it does clear up a bit of confusion
that I was having.
