JR,

I'm not changing my CSS in Calibre. I've hacked my ROM using Boroda's Russified ROM (1.05k) and changed the default CSS on the reader (under the "epub" directory). It really is a piece of cake.

Few epubs specify a font in their CSS, so the default takes over. Some DO specify the font size(s) . . . I haven't figured how to clean that up in Calibre yet.

As for the CSS code, mine's not much different that yours (or Boroda's default CSS):

Spoiler:

@font-face {
font-family: "Custom", serif, sans-serif;
font-weight: normal;
font-style: normal;
src: url(res:///Data/epub/FONT/ArialRndNrw/Serif_Regular.ttf);
}

@font-face {
font-family: "Custom", serif, sans-serif;
font-weight: normal;
font-style: italic;
src: url(res:///Data/epub/FONT/ArialRndNrw/Serif_Italic.ttf);
}

@font-face {
font-family: "Custom", serif, sans-serif;
font-weight: bold;
font-style: normal;
src: url(res:///Data/epub/FONT/ArialRndNrw/Serif_Bold.ttf);
}

@font-face {
font-family: "Custom", serif, sans-serif;
font-weight: bold;
font-style: italic;
src: url(res:///Data/epub/FONT/ArialRndNrw/Serif_BoldItalic.ttf);
}

body {
font-family: "Custom", serif, sans-serif;
text-align:left;
font-size: xx-small;
line-height: 1.2em;
margin-top: 1em;
margin-left: 0.25em;
margin-right: 0.25em;
padding-right:0.25em;
padding-left:0.25em;
}

Aside from the obvious (different fonts) the differences I see are:

- calling out the "serif" and "sans-serif" values for the font-family
- setting the justification to "left" in the body selector
- specifying the font-size in the body selector
- defining the margin sizes in the body selector

The first and third (and maybe your font file) are probably the source of your headaches.

To test which font I preferred, I used this CSS and swapped out font names in these 4 positions (pointing them toward the "regular" font instead of the appropriate bold/italic). I then pulled up the attached epub.

The epub lists 2 short paragraphs of the Lorem ibsum, repeated for each B/I combo. Using the 4 combinations, I could quickly compare 4 fonts, keep my favorite, compare against the next three, and so on.

For me, once I saw that I could drop Arial down to XS (with an XXS base font) and still read it clearly, it didn't take long for it to trounce the competition.

BTW, I downloaded the Arial MT Rounded Bold font from here. I got the link from over in the Kindle's forum.
