Making every book have the same font size.

Hello,

I use Calibre to convert books to AZW3 for use with Kindle and Kindle apps, but I have a problem. Is there any way, during a mass conversion, to make sure that all books have the same base font size. I know that fonts can be resized int he reader, but a lot of times even the largest size is too small. Most times whatever font the books have can be changed while reading, but there are some books that start out with a smaller font and even increasing the size while reading doesn't make them as big as in other books. I know there is a checkbox in Calibre to overide the publisher font so you can use whatever one you want while reading, but this doesn't seem to help the actual size. I also know that you can fiddle witht he font size in individual books, but I would like to be able to just convert them all at once with settings that I know will make them all the same size to begin with so that if I increase the font size while reading, it will be as book on each book.

Thanks.

Not really.
Calibre can scale fonts, but that assumes they have the same starting point in each book. Some set the body High (>1 ) because the <P> was low (.755em appears frequently)

This is the reason I hand edit each book.
I use font-size: 1.2em for MY ,body class. (older eyes here), 1em might meet your BASE font needs This is always the same for ALL my books.

Basic P, (I assume (inherits) 1em start by using display:block, I remove any font-size.
I scale other tags (h#, div, hr) and spans as needed
(boierplate styles get ~ .9em )

By doing it this way, I KEEP dropcaps and other display font sizes

Without looking at the CSS (code) you don't know how the book was built. Either way could result in the same appearence.

Thank you, I'll try it. I just have so many books, I was hoping or a less time-consuming fix. Thanks very much for the info though. I'll do it on the ones I know are too small at least.

I have a few clips (I happen to use Sigil, because that was what I started with) that I can drop in the proper places in the CSS, once I resolve (reverse engineer) the coding . Note I replace CODE, not the CSS as a whole.
Most books take 5-10 minutes to fine tune.

Messy code (usually word conversions without a Word stylesheet. No 2 chapters coded the same ) can take over an hour (I start by applying a consistent style sheet to all chapters, I ignore fixing boilerplate pages )

Maybe if all of the input ebooks have the same base font size. If you uncheck Disable font size rescaling, see attached, you can specify the base font size used during conversion.

I use this on a case by case basis when after converting I find the fonts are too small. See attached for my settings.

Just curious:

I happen to see font sizes in the order of .7555em, .83333333em or similar. I have heard that this used to cause (in the past) the rendering engines some extra effort (hence delays) to accomplish that precision, while it hardly worth the effort as it is barley noticeable for the casual reader. Out of habit I just always replace the above sizes with .75em and .8em and equivalent.

What is the current opinion about this?

I have either the Default Output/Default Input or Nook for both input and output set up under Page Setup. Calibre conversion will code all my text for paragraphs to 1em (which is what I prefer), but when I code any text between .8em and .95em, Calibre conversion will change them all to .75em. Then I'll have to edit them all and change them back to what I had.

I've tried checking the "disable font size rescaling," but that has never worked for me, and the font sizes get messed up for some reason.

My opinion: The majority of the text should be the BODY FONT size (and family). All else is a explicit exception (bigger, smaller, bold, italic). Technically, most paragraphs should be a simple <p> p style would set the margins and indent... for the majority of the bodies.

The stylesheet overrides this for first paragraph text, centered text... Again: Exceptions to the majority
