To reset zoom in Chrome, press Ctrl + 0 on Windows, Linux or a Chromebook, or ⌘ + 0 on a Mac. That’s a zero, not the letter O. Google describes it as “Return everything on the page to default size” in its keyboard shortcut list. It resets the site you’re on. If every site still looks too big or too small, change the default Page zoom in Settings, as shown below.
Reset zoom on the page you’re viewing
Use any of these:
- Keyboard: Ctrl + 0 (Windows, Linux, Chromebook) or ⌘ + 0 (Mac).
- Address bar: when a page is zoomed, a zoom icon appears in the address bar. Select it, then select Reset.
- Menu: at the top right, select More (three dots). Next to “Zoom,” select Zoom in (+) or Zoom out (−) until it shows 100%.
Chrome remembers the zoom for each site, so a site you zoomed last week opens at that size again. Resetting it once fixes it for next time too.
Reset zoom for every site at once
If many sites open at odd sizes, clear all the saved zoom levels in one place (Google’s zoom help):
- Open Chrome.
- At the top right, select More > Settings.
- Select Privacy and security > Site settings.
- Select Additional content settings > Zoom levels.
- Select the X next to each site to remove its zoom setting.
You can also paste chrome://settings/content/zoomLevels into the address bar to go straight to that list.
Every page is too big or too small
If Ctrl + 0 doesn’t bring pages back to normal, your default zoom has probably been changed. The shortcut returns a page to the default, so it can only be as normal as that setting:
- At the top right, select More > Settings.
- Select Appearance.
- Next to “Page zoom,” select 100%.
If only the text looks wrong, check Font size on the same page and set it back to Medium (Recommended). Google notes that some websites don’t let browsers change only the text size.
Zoom keeps changing on its own
- Ctrl and the mouse wheel. Holding Ctrl while you scroll zooms the page on Windows and Linux. A stuck Ctrl key can make every scroll zoom.
- An extension. If an extension zoomed the page, the zoom icon in the address bar names it (“This page was zoomed by” the extension). Turn that extension off at More > Extensions > Manage Extensions.
The whole Chromebook screen is too big
If everything on a Chromebook is large, including the shelf and settings, the screen size changed, not Chrome’s zoom. Press Ctrl + Shift + 0 to reset the screen resolution to default (Chromebook keyboard shortcuts).
Reset zoom on Android
Chrome for Android has its own zoom setting (Google’s Android steps):
- Open Chrome and tap More > Settings > Accessibility.
- Next to “Default zoom,” move the slider until the preview text looks right.
A zoom level you set for one site with More > Zoom is saved for that site only. Open the site, tap More > Zoom and move the slider back. If Zoom isn’t in the menu, turn on Show zoom option in main menu in the same Accessibility settings.
Reset zoom on iPhone and iPad
Tap More > Zoom text, then use Zoom in or Zoom out at the top of the screen to get back to normal (Google’s iPhone and iPad steps).
