Return your screen to normal size in seconds

Your screen is zoomed in too far, and text or icons look oversized. You can zoom back out using your keyboard, mouse, or your browser settings — whichever method you used to zoom in will work to zoom back out. The fastest way is holding Ctrl (or Command on Mac) and pressing the minus key (−) until the screen returns to normal size.

If that does not work, your zoom setting may be in your display settings rather than your browser, and you will need to adjust it there instead. The difference matters: browser zoom affects only web pages, while display settings zoom affects your entire screen, including your taskbar and icons.

Key Takeaways

  • Press Ctrl and the minus key together to zoom out in most browsers and programs; repeat until the screen looks right.
  • Press Ctrl and zero to reset zoom to 100 percent, which is usually the default size.
  • If keyboard shortcuts do not work, check your browser's View menu or your Windows/Mac display settings for a zoom or scale option.
  • Zooming in your browser only affects that browser window; zooming in your display settings affects your entire screen.

Zoom out using your keyboard

Hold down Ctrl (Windows) or Command (Mac) and press the minus key (−) on your keyboard. Each time you press minus, the screen zooms out one step. Keep pressing until everything looks the right size. This works in web browsers, word processors, spreadsheets, and most other programs.

To return to the exact default size of 100 percent, hold Ctrl (or Command) and press 0 (zero). This resets the zoom when ready rather than stepping down one level at a time. Make sure you are pressing the minus key on the main keyboard, not the minus key on the number pad — some programs respond to only one or the other.

Zoom out using your mouse or trackpad

If you have a mouse with a scroll wheel, hold Ctrl (Windows) or Command (Mac) and scroll the wheel backward (away from you). Scrolling backward zooms out; scrolling forward zooms in. This method works the same way as the keyboard shortcut and is useful if your keyboard is not nearby.

On a trackpad, hold Ctrl or Command and swipe two fingers downward to zoom out, or swipe upward to zoom in. The direction is opposite to scrolling on a mouse wheel, so pay attention to which way you are moving your fingers.

Reset zoom through your browser menu

If keyboard shortcuts are not working, your browser's View menu can reset zoom. In Chrome, Firefox, or Edge, click the menu button (three horizontal lines in the top right corner) and look for a "Zoom" option. You will see a percentage — click the minus button next to it, or click the percentage itself to type in a custom zoom level.

In Safari on Mac, click the Safari menu at the top left, select "View," and then click "Zoom Out." You can also use the keyboard shortcut Command and minus, which works the same way as other browsers. The menu method is slower but works when keyboard shortcuts do not respond.

Check your display settings if the whole screen is zoomed

If zooming in your browser did not fix the problem, or if your entire screen (not just one window) looks too large, the zoom setting is in your operating system, not your browser. On Windows 10 or 11, right-click on your desktop and select "Display settings." Scroll down to "Scale and layout" and look for a percentage — it is usually set to 100 percent. Click the dropdown and select a smaller percentage like 75 or 90 percent.

On Mac, click the Apple menu, select "System Settings" (or "System Preferences" on older versions), then click "Displays." Look for a "Resolution" or "Scaled" option. Select the option that says "Default" or shows the largest screen size — this is the normal, unzoomed view. You may need to restart your computer for the change to take effect.

Zoom settings that stick to one website

Most browsers remember your zoom level for each website. If you zoom out on one site and then visit it again later, it will still be zoomed out. If you want to reset zoom for just one website without changing your default, use the reset shortcut Ctrl + 0 (or Command + 0 on Mac) while on that site.

If you want to zoom a specific website every time you visit it, zoom in or out to your preferred level and close the browser — the setting will be saved automatically. There is no need to manually save zoom preferences. The next time you visit that site, your zoom choice will still be there.

Common reasons zoom gets stuck

If you zoom out but the screen does not change, check whether you are holding the right modifier key. Ctrl is correct on Windows; Command (the key with the Apple logo) is correct on Mac. Holding Alt or Shift instead will not work. Also verify that your browser window is active — if another window is in focus, the keyboard shortcut may not reach your browser.

If your entire screen is zoomed and keyboard shortcuts do not work, your zoom setting is in your operating system display settings, not your browser. Follow the Windows or Mac instructions in the section above. If you have recently updated your operating system or installed new software, restart your computer — sometimes zoom settings do not take effect until you restart.

Frequently Asked Questions

Why did my screen zoom in by itself?

You may have accidentally pressed Ctrl and the plus key, or Ctrl and scrolled your mouse wheel forward. Some programs also zoom in when you double-click text or images. Check whether you recently changed any settings, or restart your browser to see if the zoom resets to default.

Can I set a default zoom level so I do not have to reset it every time?

Yes. Zoom in or out to your preferred level in your browser, then close and reopen the browser — most browsers save your zoom preference for each website automatically. If you want to change the default zoom for all websites at once, look in your browser settings under "Appearance" or "Display" for a default zoom option.

Is there a difference between zooming in my browser and zooming in my display settings?

Yes. Browser zoom affects only the text and images on web pages; your taskbar, icons, and menus stay the same size. Display settings zoom affects your entire screen, including everything. If only your browser looks too large, use browser zoom. If your whole screen looks too large, use display settings.

What if I zoomed in on my phone instead of my computer?

On iPhone, pinch two fingers outward on the screen to zoom in, or pinch inward to zoom out. On Android, use the same pinch gesture, or go to Settings, select Accessibility, and look for a Magnification option. You can also try double-tapping with two fingers to zoom out quickly.
