How does one change the text for Chrome's address bar font size? I need to make it larger, more readable, especially for high-resolution monitor displays.

This font size is NOT for the displayed web-page content(s).

I'm running macOS 10.12.6, Chrome Version 67.0.3396.99 (Official Build) (64-bit). I want to do it for macOS 10.13, too.

Use TinkerTool to change the System font.

Problem is, making larger System fonts can do wonky things not only in Chrome but other apps/windows. Other than trying diff font sizes, how can I adjust for this in Chrome? Maybe I can increase the address-bar height somehow - possibly by making larger extension icon sizes, or some other customization settings I've not yet found? Suggestions welcome.

TinkerTool System font The following shows an example of problems with System = 24:

wonky font size makes Chrome silly (I'm the question author. Default System font size for my MacBook = 13.)

    After some "tinkering," System = 17 works pretty well for me. And it's a decent visual upgrade to see the 'https://...' text better on my 32", 4k display monitors. Jul 22, 2018 at 20:29

In addition to or separately from my other answer, you can change the display resolution to 'Larger Text', or a similar setting. This also changes the fonts for all screen elements in all applications - which may or may not be desired.

I experience good results when employing both this solution and the one from my other answer.
