I collected data on sizes of some 20 HTML-formatted messages that I received. I then looked at the sizes of the text in ASCII. The mean bloat factor was 3.7. Thus, a 25 KB ASCII message (your example) could easily exceed 90 KB if HTML-formatted. I also looked at the quality of the HTML in HTML-formatted messages. The mean number of errors reported by <http://validator.w3.org/> was 9.1 errors per KB of file size. Thus, your example of a 25 KB ASCII message converted into an HTML-formatted message might contain as many as 840 HTML errors. Of course, these statistics are highly dependent on the E-mail application used to format and send the message. I did not examine what applications were in use for the 20 messages.
