How to Automatically Enlarge Small Fonts in Safari on Mac
In Safari, you may be familiar with increasing or decreasing the font size on a website-to-website basis using the Command+Plus (“+”) and Command+Minus (“-“) keyboard shortcuts. But if you don't want to fiddle with those settings for every site, Safari allows you to increase the minimum font size and have it apply to all the websites you visit.
This is similar to Safari's Page Zoom feature. While the zoom feature enlarges both the content and the text, the font size feature retains the original page formatting and doesn't touch the media on the page.
To get started, open the Safari browser on your Mac. Click “Safari” in the top menu bar and choose “Preferences” from the drop-down menu.
In Safari Preferences, click the “Advanced” tab.
In the “Advanced” tab, locate the “Accessibility” section and click the check mark next to “Never Use Font Sizes Smaller Than.” In the drop-down menu, choose between “14,” “18,” or “24” -point font sizes.
If you find the text really hard to read, go with the 24-point font size, which will double the default text size for most websites. However, for some people, the 18-point size is the sweet spot.
Instantly, you will see the text in all open websites change to a larger size.
If you change your mind later and want the smaller font sizes back, click “Safari” in the menu bar and navigate to Preferences > Advanced, and then uncheck the “Never Use Font Sizes Smaller Than” option. Alternately, you can simply select a smaller font size from the menu.
If you'd like to do the same thing on your iPhone or iPad, you can't make a blanket change that applies to all websites, but you can increase or decrease the font size on any web page in Safari in just a few taps. Happy browsing!
