Microsoft Edge Disable Zoom or Reset Zoom Level at Every Start

Microsoft Edge has a page zoom feature that you can configure by clicking More (the icon showing three docs) or with Ctrl + Mouse scroll like any other browser. Edge doesn’t maintain the zoom factor setting for individual websites.

Google Chrome, on the other hand, maintains the zoom settings per-website, and you can also choose the default zoom factor.

If you don’t use the zoom feature in Edge, to prevent accidental zoom using Ctrl + Mouse scroll, pinching, and stretching (in touch devices), you may want to disable zoom using the registry. Also, you can preset the (default) zoom factor before locking down the feature.

This post has the registry settings to disable Edge’s zoom feature, lock down the zoom level at 100%, or auto-reset the zoom level whenever you start Edge.

Note: Information in this article does not apply to the new Microsoft Edge (Chromium). It’s applicable to the old Microsoft Edge browser only.

Update [2019]: The registry edits in this article no longer work in Windows 10 v1809 and higher.

Disable zoom feature in Microsoft Edge [Lock it at 100%]

1. First, set your preferred zoom factor (say 100%) in Microsoft Edge before proceeding to disable the zoom option.

2. Start the Registry Editor (regedit.exe)

3. Go to the following branch:

HKEY_CURRENT_USER\SOFTWARE\Classes\Local Settings\Software\Microsoft\Windows\CurrentVersion\AppContainer\Storage\microsoft.microsoftedge_8wekyb3d8bbwe\MicrosoftEdge\Zoom

4. Create a DWORD value named ZoomDisabled

5. Double-click ZoomDisabled and set its data to 1

If you didn’t set the desired zoom level in step 1 or want to change it in the registry later, use these steps:

6. Create a DWORD value named ZoomFactor

7. Double-click ZoomFactor and set its data to 186a0 (for 100%). To fix the zoom factor at 125%, use 1e848

Lock / Fix the zoom level at	hex	decimal
100%	186a0	100000
110%	1adb0	110000
125%	1e848	125000

7. Exit the Registry Editor.

Reset zoom level (100%) automatically whenever you start Edge

There are situations where you need the zoom feature especially when browsing legacy and non-responsive webpages showing small fonts (with fixed “px” values) that don’t scale accordingly. So you may want to use the zoom feature for the current browsing session, but would like to have the zoom factor reset to 100% at every start. Here is a registry setting that does that exactly.

In the registry key mentioned previously, create a DWORD value named ResetZoomOnStartup2 and set the value data for ResetZoomOnStartup2 to 1.
