How do you change the Markdown preview font size in IntelliJ IDEA?

Question

How do you change the Markdown preview font size in IntelliJ IDEA 2017.1? The default font size is so small it's useless.

I've tried changing:

Preferences > Editor > Colors and Fonts > Font > Primary font
Preferences > Editor > Colors and Fonts > Font > Secondary font
Preferences > Editor > Colors and Fonts > Markdown
  (this doesn't have any font or size options)
⌘->scroll wheel

I can change the font size in editor windows, but I haven't found the trick for changing the Markdown preview window font.

I also use

Preferences > Appearance & Behavior > Appearance > Override default fonts by

And even that doesn't change the font size.

I'm using

IntelliJ IDEA 2017.1

Answer 1

At the moment, font size for the preview can be changed only via custom CSS.

body {
    font-size: 80% !important;
}

As of 2.6.2024 (that is d.m.yyyy) you can go to File > Settings > Languages & Frameworks > Markdown > Preview Font Size. [1

Answer 3

File > Settings > Search for 'preview' > Page Zoom (allows values from 0.1 to 10). If you set this to around 1.5 it works well. Use the decimal places to get it just right.
