The quickest way to shrink text on your screen

The fastest method on almost any computer is to hold Ctrl (on Windows or Linux) or Command (on Mac) and press the minus key (–) one or more times. Each press makes the text smaller. You can undo it by pressing Ctrl or Command and the plus key (+), or reset everything to normal size with Ctrl/Command + 0.

This keyboard shortcut works in web browsers, email programs, word processors, and most other applications. The text shrinks when ready, and the change stays in place until you enlarge it again or close the program.

If your keyboard does not have a separate minus key, you can also use the scroll wheel on your mouse while holding Ctrl or Command—scroll down to shrink, scroll up to enlarge.

Key Takeaways

  • Hold Ctrl (Windows/Linux) or Command (Mac) and press the minus key to make text smaller when ready in most programs.
  • The same shortcut with the plus key makes text larger again, and Ctrl/Command + 0 resets to the default size.
  • Scroll wheel zoom works in browsers and many applications—hold Ctrl or Command and scroll down to shrink text.
  • Operating system settings let you change the default text size for your entire computer, affecting menus, notifications, and system text.
  • Individual programs often have their own font size controls in the View or Format menu if you want permanent changes in that app only.

Changing font size in your operating system settings

If you want text to be smaller across your entire computer—not just in one window—you can adjust the system-wide font size. On Windows 10 or 11, go to Settings > Display > Scale and layout, then change the "Scale" percentage. Moving it down from 100% makes all menus, notifications, and system text smaller.

On Mac, open System Settings > Displays, then look for "Resolution" or "Scaled" options. Choosing a higher resolution makes everything on screen smaller because more pixels fit into the same physical space. You can also go to System Settings > Accessibility > Display and adjust "Text size" to change just the font in menus and notifications.

These system-wide changes take effect when ready but may require you to log out and back in, or restart your computer, for some programs to recognize them. Be aware that making text too small can make your screen harder to read and may cause some older programs to display incorrectly.

Adjusting font size in specific programs

Most applications have their own font size controls separate from the keyboard shortcut. In web browsers like Chrome, Firefox, and Safari, you can go to the menu (usually three horizontal lines or dots) and look for "Settings" or "Preferences," then find a "Fonts" or "Text size" option. Some browsers also let you set a minimum font size so no website can make text too small to read.

In Microsoft Word, Google Docs, and other word processors, you can select the text you want to change and use the font size dropdown menu in the toolbar—usually showing a number like "12" or "14." In Outlook and other email programs, look under Tools > Options > Mail Format to change the default text size for all new messages you compose.

For Windows Notepad and similar text editors, go to Format > Font to open a dialog where you can pick a smaller size. These program-specific changes usually explore only to that process and do not affect other programs on your computer.

Making text smaller in web browsers

Browsers remember your zoom level for each website, so if you shrink text on one site, it stays small the next time you visit. You can also set a default zoom level that applies to all websites. In Chrome, go to Settings > Appearance and adjust "Page zoom." In Firefox, go to Settings > Home > Fonts & Colors and change the minimum font size or default zoom level. Safari on Mac has zoom controls in View > Zoom In/Out.

If a website has text that is too small and the zoom shortcut does not help enough, you can also use your browser's reader mode (available in Firefox, Safari, and Edge) which reformats the page and lets you adjust text size independently. This strips away ads and sidebars, leaving just the article text in a size you choose.

Adjusting font size on your monitor itself

Some monitors have physical buttons or an on-screen menu that lets you change text size at the hardware level. Look for buttons on the bottom or side of your monitor labeled "Menu" or with arrows. Once you open the menu, look for options like "Text Size," "Sharpness," or "Clarity." This method is less common on modern monitors but can help if your monitor is displaying text unclearly.

This is different from changing your computer's settings—it only affects how the monitor displays the signal it receives. If your monitor has this feature, it is worth exploring if you find text blurry or hard to read even after adjusting your computer's zoom.

Troubleshooting when font size changes do not work

If the Ctrl/Command + minus shortcut does not shrink text in a particular program, the program may not support zoom. Try using the program's own menu instead—look under View, Format, Tools, or Preferences for a "Font Size" or "Text Size" option. Some older programs or specialized software do not respond to the standard keyboard shortcut.

If text is still too large after you have tried multiple methods, check whether your operating system's accessibility settings are overriding your changes. On Windows, go to Settings > Accessibility > Display and make sure "Text size" is not set to a larger value. On Mac, check System Settings > Accessibility > Display for any text size adjustments.

If you are using a projector or external monitor and text appears smaller than on your main screen, the issue is usually the resolution or scaling of that display. Right-click on your desktop (Windows) or go to System Settings > Displays (Mac) and adjust the resolution or scale for that specific monitor.

Frequently Asked Questions

Why does the font size shortcut not work in some programs?

Not all programs support the standard Ctrl/Command + minus zoom shortcut. Older software, specialized applications, and some desktop programs use their own font size controls instead. Check the program's View or Format menu for a font size option, or look in the program's settings or preferences.

Will changing my system font size affect all programs?

System-wide font size changes affect menus, notifications, and system text, but individual programs may override these settings with their own zoom level. For example, if you zoom a web page smaller, that zoom stays even if you later change your system font size. You may need to adjust both.

Can I set a different font size for different monitors?

Yes. On Windows, go to Settings > Display, select the monitor you want to adjust from the dropdown, then change the Scale percentage for just that monitor. On Mac, go to System Settings > Displays, select the monitor, and adjust the resolution or scaled setting independently for each display.

What is the difference between zoom and font size?

Zoom makes everything on the page or window smaller or larger together—text, images, buttons, and spacing all scale proportionally. Font size changes only the text itself. Zoom is usually what you want for readability; font size controls are better when you want to adjust just the words without changing layout.

How do I make text smaller on my phone or tablet?

Phone and tablet font size controls are different from computers. On iPhone or iPad, go to Settings > Accessibility > Display & Text Size and adjust "Larger Accessibility Sizes" or "Text Size." On Android, go to Settings > Display > Font size or Advanced > Accessibility and look for text size options there.
