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
Build #IC-171.3780.95, built on March 20, 2017
JRE: 1.8.0_112-release-736-b13 x86_64

IntelliJ 2022.3.3 seems to match the preview font size with whatever font size is set in the editor (for example, using ⌘+scroll wheel) – Cypro

Answer 1

Settings | Languages & Frameworks | Markdown | Preview font size.

Original answer for older IDE versions:

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

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

If you are interested how the default CSS looks like, it can be found on GitHub here: github.com/JetBrains/intellij-plugins/blob/master/markdown/… – Promulgate

@Promulgate 's link is broken now that the code was moved to the Intellij Community Repo. The default CSS can now be found here – Holmium

That's a bit unfortunate that it's not easier. Even scrolling with mouse-wheel doesn't adjust it, even if set to adjust for codes. – Pelotas

This comment is no longer the only working way of achieving this. Going through the Settings Dialogue is likely going to be a lot easier for most people. – Divertissement

Answer 2

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.
