What is the right font-size??

[augfan77]

Hi guys,
I have been associated with a financial site for the last 9 months. It is forum based site. A few days ago we had changed the font-size in the home page. We want to make sure that we have the perfect font-size for the visitors.Could you guys suggest the most user friendly size?
Looking forward to some replies.
Thanks,
Augastin

Look at http://www.phpbb.com/styles/demo.php

then look at the source code; at one place it shows

/* General text */
.gen { font-size : 12px; }
.genmed { font-size : 11px; }
.gensmall { font-size : 10px; }

/* The content of the posts (body of text) */
.postbody { font-size : 12px; line-height: 18px}
a.postlink:link { text-decoration: none; color : #006699 }
a.postlink:visited { text-decoration: none; color : #5493B4; }
a.postlink:hover { text-decoration: underline; color : #DD6900}


so that gives you some idea. The font size never seems to be over 12px and a lot of the general text is 10px.
