Specify Minimum Font Size in Safari 10.0, macOS Sierra

Question

The Minimum Font Size option seems to be missing in Safari 10.0 / macOS Sierra. It's been replaced by Page Zoom (prefs > advanced). I'm specifically asking how to prevent Safari in Sierra from ever using a font size below a certain value. I don't want to have to fix this on a site by site basis.

Let's say I want to set 11px as the minimum font size in Safari on macOS Sierra. How do I do this?

Answer 1

use

defaults write com.apple.Safari com.apple.Safari.ContentPageGroupIdentifier.WebKit2MinimumFontSize -int 14

… restart Safari, be happy again! (replace 14 with whatever suits you)

edit: as OP said, paste the line into terminal, sorry for omitting this initially!

Answer 2

Since there's not currently a 'minimum font size' option in version 10 of Safari, I see two possible workaround options open to you:

1. Using a custom style sheet
2. Installing an extension

Style sheet

If you know how to create your own style sheet, then follow these steps:

1. Create a style sheet to set your font properties
2. Go to the Safari > Preferences menu
3. Select the Advanced tab
4. In the Style Sheet drop-down menu, select Other...
5. Navigate to your style sheet and select it
6. Exit the Safari preferences.

Note: If you want your style sheet to apply the font size to all elements, you can use an asterisk to imply that your code runs on all elements. For example:

* {
 font-size: your value;
 font-family: your font;
 font-weight: your value;
}

Extension

There are probably many extensions that will achieve what you want. Here are the steps for one that I'm aware of:

1. Go to: https://safari-extensions.apple.com/details/?id=com.sobolev.stylish-5555L95H45
2. Install the Stylish extension
3. Restart Safari
4. Take note that to the left of the address bar you should now see the Stylish S button
5. Go to: https://userstyles.org/styles/68263/global-font-size
6. Click on the Install with Stylish button
7. You've now installed this style

Now, if you need to customise this style, do the following:

1. click on the Stylish S button I referred to at Step 4 above.
2. Click on Manage
3. Under the Global Font Size option click on Edit
4. This displays the CSS code for this style. Edit it as you need.
5. Save your changes

Note: If you want your style sheet to apply the font size to all elements, you can use an asterisk to imply that your code runs on all elements. For example:

* {
 font-size: your value;
 font-family: your font;
 font-weight: your value;
}

Feedback

Anyone wanting Apple to return the 'minimum font size' option to Safari should send them feedback via the Safari feedback page.

Hope this helps.

Go to Finder then Applications click on Safari then go to view in the menu bar click and a drop down list appears click on, Show view options, and a drop down box appears Applications where you will see a text sizing box set to your preference and set as default.
