Increase font size chrome console

If you are on a Mac, are using a japanese keyboard, and want to zoom the console temporarily, the short-cuts are:

Zoom In: ⌘ ^

Zoom Out: ⌘ -

Reset Zoom: ⌘ 0

Other Applications are using + for zooming in, but because on japanese keyboards the plus-sign is on the second level, it is only accessible with shift. So: ⌘ ⇧ +

That where it gets weird, because to Chrome ⌘ ⇧ + apparently means "Zoom Content". If you are in the Javascript console, and do ⌘ ⇧ +, the window's content area in zoomed in. But doing a Zoom-out ⌘ - moves the focus back to the console and zooms it out. Result: The content is getting larger, the console smaller. Aaarggghhh.

If you just need a quick, temporary size bump you can press Ctrl + / - to zoom and Ctrl 0 to reset.

1. Open Browser
2. Open Console.
3. Press Ctrl+.

I hope it will help you

Here's a pretty recent blog post on the subject.

Basically, override Default/User StyleSheets/Custom.css in your user directory with something like:

/* Keep .platform-mac to make the rule more specific than the general one above. */
body.platform-mac.platform-mac-snowleopard .monospace,
body.platform-mac.platform-mac-snowleopard .source-code {
    font-size: 11px !important;
    font-family: Menlo, monospace;
}

body.platform-windows .monospace, body.platform-windows .source-code {
    font-size: 12px !important;
    font-family: Consolas, Lucida Console, monospace;
}

body.platform-linux .monospace, body.platform-linux .source-code {
    font-size: 11px !important;
    font-family: dejavu sans mono, monospace;
}
