AZW3 files have different font size

Buhaj47 · 12-05-2021, 06:40 AM

I converted a couple of EBUB files into AZW3 and sideloaded to my Kindle, but they have a different font size at the same setting, i.e. one book at font size 3 has a bigger font than another one at the same value. Am I forgetting a setting in Calibre that ensures body text has the same size across all books? This is my current setting:

Look at the top of your screenshot, you have disabled font size rescaling.

Thanks, it crossed my mind it may be the case - what value should be set here so that all ebooks are following the device setting, i.e. when I set 20 in KOReader, it's really 20? 0.0 pts is best?

I've enabled font size rescaling and set the value to 0.0 pt - just opened a book in KOReader now (EPUB) and noticed its font is bigger nonetheless. Tested on several other books but those look fine. Does the 0.0 pt value not do anything or is it a matter of the specific EPUB file?

Actually just opened an EPUB with the "correct" size and its body CSS is like this:

Code:

.calibre5 {
    display: block;
    text-align: justify;
    text-indent: 1em;
    margin: 0
    }

while the one with too big font is

Code:

.calibre6 {
    -moz-hyphens: auto;
    -webkit-hyphens: auto;
    adobe-hyphenate: none;
    display: block;
    font-size: 1em;
    hyphens: auto;
    orphans: 2;
    text-align: justify;
    text-indent: 1.5em;
    widows: 2;
    margin: 0
    }

Wonder why the 2nd book has font-size to it?

You need the Big (CSS) Picture
CSS stands for Cascade Style Sheet

Body

Div

P

Any of those could affect the font size (and other attributes)

In the affected book it's the following

Code:

 <body class="level">
            <h1 class="ch">34</h1>

<p class="calibre6">

The two classes are

Code:

.level {
    -moz-hyphens: auto;
    -webkit-hyphens: auto;
    adobe-hyphenate: none;
    display: block;
    font-size: 1em;
    hyphens: auto;
    orphans: 2;
    padding-left: 0;
    padding-right: 0;
    text-align: justify;
    widows: 2;
    margin: 0
    }

Code:

.ch {
    -moz-hyphens: none;
    -webkit-hyphens: none;
    adobe-hyphenate: none;
    display: block;
    font-size: 1.66667em;
    font-weight: bold;
    hyphens: none;
    text-align: center;
    text-indent: 0;
    margin: 1.5em 0 3em
    }

Could you please also post the calibre6 class. The ch class (chapter header) is applying to the chapter number and would not affect the paragraphs.

The code is in post #4.

Interesting then since both level and calibre6 set the font size to 1em. Are there any @page entries in the CSS?

It might be easiest if the book was public domain, you could attach it to a message here. If the book is not public domain, use the ScrambleEbook plugin to generate a copy that you could attach here.
