I am currently experimenting with the new font-face feature in CSS3 to use custom TTF/OTF fonts. My question is: can I adjust the default font size ratio? For example, if I am using Tahoma with a default 9pt font size and want to switch to my own custom font file, the issue arises where the custom font at 9pt appears much smaller than Tahoma at 9pt when viewed in a browser that supports @font-face. Is there a way to increase the size ratio of the custom font to match Tahoma?
