AZW3 to PDF for iPad Pro 10.5-inch: Recommended Settings?

[teleos]

I would like to convert an AZW3 to a PDF that will display optimally on my iPad Pro 10.5-inch. (My iPad's screen resolution is 2,224 x 1,668, and I primarily use PDF Expert to read PDFs on the device.)

Using Calibre's default settings, the results are quite decent, but I'm wondering if further improvements are possible...

Can anyone recommend which conversion settings I should select or change to yield best results? I realize a lot of this may boil down to user preference, but I am new to Calibre and looking for some good suggestions with which to begin -- or any options that are universally a good idea to choose given my setup.

Thanks!

Although I am no expert ...I use this setting for the 10.5" ipad pro:

@page {
size: 6.5in 8.5in;
margin: 5mm 5mm 5mm 7mm !important;
}

I like larger font sizes so I set the font to 1.4em and select a font that has a slightly heavier weight than regular.
This combination is perfect for the screen size. You can play around with the margin settings.

These settings are in the prince pdf stylesheet of the Prince sigil plugin that I use to convert to pdf.
There is also a calibre prince pdf plugin (windows) that allows you to adjust the settings, so you don't need to leave calibre to do the conversion.

Many thanks! I'm now experimenting with Prince in its various forms (with Calibre, with Sigil, and as a standalone).

Do you mind sharing your entire stylesheet? The default one I'm working with seems to be creating some odd-looking output!

Is the odd output from the sigil prince pdf epub conversion?
After trying various combinations of prince style.css with the epub stylesheet I settled on a very simple prince style.css. I am not into printing pdfs for books so all the @page referencing counters and left and right pages etc, I don't have in my prince stylesheet. I also prefer to add page numbers post processing.

Basically I just have something like this (fonts as required).

@font-face {
font-family: serif;
src: local("Linux Libertine")
}

@font-face {
font-family: serif;
src: local("Noto Serif")
}


@page {
size: 6.5in 8.5in;
margin: 5mm 5mm 5mm 7mm !important;

}

@prince-pdf {
prince-pdf-open-action: zoom(fit-page)
}

body {
widows: 1;
orphans: 1;
text-align: justify;
font-size: 1.4em;
hyphens: auto;
}

Prince reads the epub css first so I specify font family weight and style there.

I have duplicates of sigil prince plugins set to different sizes. So the general pdf layout is the same except for screen size and font family/size.

I want as much text as possible to fill the ipad screen, so I leave the margins clean of things like author names/chapter titles.

One thing I do in the epub stylesheet before conversion to pdf is have the toc link 2 ways. Entries in toc>ch heading, ch heading>toc.
