Next time, install Rightsizer Safari Ex... with 1-click

Rightsizer Safari Extension is a replacement for the "zoom text only" feature of Safari. Unlike Safari's built-in text zoom, Rightsizer lets you zoom specific kinds of text (that is, text elements of a particular class or ID), instead of all the text on a page. And it remembers your font size settings for every Web site and automatically reapplies them the next time you visit a site.

To use Rightsizer, click some text and keep the mouse button down. While the mouse button is down, press:

  • the A key to make the text bigger,
  • the Z key to make the more...

What's New

Version 1.2:
  • Added option to take over Safari's zoom hotkeys. If enabled, pressing ⌘+ or ⌘- will cause Rightsizer to zoom the whole page in or out. As usual, the zoom level will be remembered on a per-site basis. This option has no effect on Safari's menu items and toolbar buttons for zooming.


  • Mac OS X 10.5.8 or later
  • Safari 5.0.1 or later
