    This is currently expected behavior. It provides an easier way to adjust
    the output size than having to specify a universal font size or custom
    CSS for print/PDF output of a given document. I understand that it's not
    necessarily intuitive, though, so I may add an export option to always
    print/export at 100%.

    Apologies if this is already answered, I've seen this topic come up in different contexts on but couldn't figure out the final answer.

    My goal is to produce a document with 10pt font (not by choice, FWIW, by requirement). I ended up doing the following:

    • Choose Swiss
    • Select 70% zoom because I see in CSS:

    body {
    font-size: 15px; --> 10/15 ~ .67 line-height: 21px; margin: 0 auto; }

    So this works Good Enough. What I'm not so clear on is the meaning of the option:

    "Custom font size for export ".

    Clicking On and Setting this to different values seems to change the exported output but not to 10 pt. Perhaps some sort of scaled-10-pt?

    The custom font size essentially adds a font-size: XXpx !important to the output, which should override whatever is in the style. It's a bit screwy right now, as half of the built-in styles are using rem/em to base sizes off of what's specified for the html/body. Because I assume that when setting a custom font size, users would still want headlines and other elements that differ from the paragraph font size to scale accordingly, I'm going to need to find a way to normalize the themes and provide a mechanism that will work with unpredictable custom themes.

    So at this point, the "Custom font size for export" is a bit of a gamble. If you need an exact output font size, the best bet right now is to create a custom theme that outputs exactly what you intend. All of the CSS for the default styles as well as a collection of custom styles is available at https://github.com/ttscoff/markedcustomstyles.

    Thanks for the detailed explanation. They accepted my zoom-ing hack for now, so I’m good. But if they get persnickety I’ll do as you say with the explicit CSS.
