On Windows and, if I'm not mistaken, on Linux, it's possible to zoom in and out in Google Chrome using the mouse wheel. However, this doesn't seem to be working on Mac OS X.

Does anybody know if this feature can be enabled? Or is there any alternative solution (plugin, script, etc.)?

You can pinch to zoom, which will simulate Command ⌘+ and Command ⌘-

You can also try the extension, which was mentioned by in Danijel's answer.

Otherwise, you can hold down Control ^ and the screen will zoom in and out. It ends up looking like this though (which I don't think you want):

  • The extension mentioned does not work on recent Macs. – Aidan Feb 20 '15 at 10:48
  • Hold down control in some OS should work only if the option Use scroll gesture with modifier keys to zoom is flagged – JeanValjean Oct 3 '16 at 11:16
  • Pinch is a good alternative solution, but it doesn't work on a mouse with an actual physical scroll wheel. :( – Jon Freed Apr 2 at 13:57

Using this extension from taharactrl I was able to zoom with ctrl+mouse wheel on all websites.

OSX El Capitan + Chrome 47

Note : after installing the extension, for it to work on existing opened tabs you have to reload them.

  • I can confirm this works under OSX El Capitan & Chrome 54 (Nov 2016). – Hotschke Nov 21 '16 at 16:46

Use Command and the + button to zoom in!

  • True, but the question was about how to do it with the mouse scroll wheel, presumably so you don't have to take your hand off the mouse. – Jon Freed Apr 2 at 13:52

In yosemite, you can activate it at the system level. For example:

Preferences > Accessibility > Zoom > Use scroll gesture with keys to zoom

Select ^ control

Then use control and the mouse scroll to zoom.

(Alternatively, tough that's not what's asked, in chrome, you can pinch to zoom by default)

    The problem with this approach is that it actually zooms the screen. It does not simply change the font size and spacing. (use em's people) – DRaehal May 27 '16 at 17:40

There's a Google Chrome extension you can use to do this.
Note: This no longer works!


Hold down Control as you scroll and it will zoom in/out.
Note: Use this instead!

    -1 On OS X Yosemite: Tried extension. It said to hold right mouse button and scroll to zoom - that worked on 1 page but inconsistently, and not at all on 9 other pages I tried (including this one). Also, <kbd>Control</kbd> scroll and <kbd>command</kbd> scroll don't work by default - that's what the question is. – Stan Kurdziel Feb 5 '15 at 19:22

    Indeed the extension does not work on OS X Mavericks either. – Aidan Feb 20 '15 at 10:49
  • Does not work in Chrome 69 on MacOS 10.13 – Nate Sep 17 '18 at 19:41
