Libra 2 How to set default line spacing?

[Phssthpok]

I have a lot of books without any line-height specification in the CSS. They all seem to display with a default line spacing which seems to be equivalent to "line-height:1", which is too close together for my taste. I can manually adjust the spacing for each book individually, or I could add "line-height:1.2" to each and every book, but either way this is a lot of work.

Something, somewhere must be specifying the default line spacing. How do I change it?

It depends on the font you use. Some fonts have narrow line-spacing, others have wider.

Also, you don't have to add line-height to each book separately. You can use the Modify Epub plugin to add extra css to books in bulk.

I think you can also edit the Kobo configuration file, specifically Reading settings.

I have set up Bookerly as the default font, as it was Georgia before (which is missing many glyphs, as well as looking unpleasant. I can't remember how I did it, though...).

So the books involved all have the same font but a line spacing I would like to change.

Ah, that's where I set the font (readingFontFamily=Bookerly). It has "readingLineHeight=1.35". I'll try increasing it to see what happens.

Thanks!

Omitting it might work better.

Investigating further, one of the books with this problem has a base font size of 1.29167em, which is then rescaled in each paragraph style to 0.77419em. 0.77419 x 1.35 is 1.045em, which looks like the line spacing I end up with. A lot of books seem to do this -- I've never understood why.

Here is what you do. Take a book you've not opened and open it. Then set the font, font size, font weight, margins, and line height. Then that will become the default for any new books.

When you open any previously opened eBooks, just set the same settings from the Aa menu and you'll be good.

For any books that have the font size set at a different size to 1em be it larger or smaller, you'll have to go in and edit them to fix it.

Books with no font size for the body font will default to 1em and your font size setting will be as you want it to be.

Stupidity.

Unfortunately, the only options for books like this are to either edit every book you buy to delete such nonsense or to edit the font settings to compensate when you first open a book. I believe you can also use KOReader to override book CSS and force your own rules onto every book you read, but since I've never used KOReader myself, I don't know how effective the overrides are.

That is not a solution at all. The only solution is you edit every eBook to check the CSS for stupid stuff and fix it.

FWIW, I use calibre to do conversions (including epub to epub), and don't seem to have a problem with varying line heights between books.
