Edge Zoom Level

September 14, 2015

I recently ran into a odd problem where the Edge browser’s default zoom level got stuck at 80%. The frustrating bit was that changing it only effected the current page, clicking any link to a new page resulted that page displaying at 80%.  In my search for a fix I found a few others with the same issue (although everyone seems to have a different percentage, and most seemed to be > 100%).

Before I explain how I resolved the problem there are a couple of vital caveats:

At the moment I’m unclear exactly how I got into a broken zoom state, but the fix seems to have held. I’ve been trying for a while to reproduce the problem but at the moment it seems to be holding steady.

Edge is a UWP application. As such, it’s registry settings are a bit buried; they live under HKEY_CLASSES_ROOT rather than CURRENT_USER or LOCAL_MACHINE. In particular they can be found at HKEY_CLASSES_ROOT\Local Settings\Software\Microsoft\Windows\CurrentVersion\AppContainer\Storage\microsoft.microsoftedge_8wekyb3d8bbwe\MicrosoftEdge.


From there you will find several subkeys, including one named Zoom. Zoom has a single DWORD value named ZoomFactor.


The value directly relates to the zoom percentage (which in my case was 80,000). Setting this value to 100,000 results in a 100% zoom.


Once I changes this to 100000, Edge began giving me the default I expected. For those looking for the “quick fix”, here is a Gist of the regex export:
