Some web pages may use a font size that doesn’t render properly in different browsers on various platforms. If you find yourself squinting at a web page, this simple keyboard shortcut can help.


To increase the font size of the current web page, press command + by holding down the command key (with the apple and the squiggly) and pressing a plus key (no shift required).

To reduce the font size, press command - (command and minus).

I’ve tested this with Safari and Firefox. It may work with other browsers and applications.

  • Modern browsers have replaced this functionality with full-page zoom. So, you'll have to select a "Zoom Text Only" option beforehand. Also, keep in mind that most websites are not engineered with larger font sizes in mind. Because of this, many times the layout will break resulting in something that is not legible.
