Not if the college is deliberately trying to hide that information—they'll make the acceptance and rejection letters the same size.
Most systems have a finite limit to the sizes of the messages they can handle. (If nothing else there are practical limits to both the maximum transfer rate and the operators' patience.) It's inefficient, but you can pad all messages to that length regardless of the size of the plaintext.
