The font size option lists size 8 to 72. However, when one chooses any of the font sizes, the actual size result is not the same as the true font size. I customarily use font size 12 in documents and the posting size on this site is much smaller--both in the preview and actual posting--than the real font size. To get it to look like a size 12 I have to choose size 18.
Why? Can someone in web administration fix this?
