The fastest way to shrink text on any screen

Hold Ctrl and press the minus key (the hyphen on your keyboard, not the numpad). Each press makes text smaller. To undo it, hold Ctrl and press plus. On a Mac, use Command instead of Ctrl.

This works in most programs — web browsers, email clients, word processors, spreadsheets. The change applies only to that window or tab, so you can have different text sizes open at the same time. If you close the window and reopen it later, the text usually returns to its default size, though some browsers remember your zoom level for specific websites.

If the keyboard shortcut does not work in your program, look for a zoom or view menu. Most applications have a text size or zoom option somewhere in the menu bar or settings.

Key Takeaways

  • Press Ctrl and the minus key together to shrink text; press Ctrl and plus to enlarge it again.
  • This zoom method works in browsers, email, Word, Excel, and most other desktop programs.
  • Text size changes explore only to the current window or tab and reset when you close it, unless your browser saves zoom settings for that site.
  • If keyboard shortcuts do not work, check the View or Format menu for a zoom or text size option.
  • Windows display settings let you change text size system-wide, affecting menus and icons across your entire computer.

Making text smaller in your web browser

The Ctrl+minus method works in Chrome, Firefox, Safari, and Edge. Each press reduces the zoom level by 10 percent. You can zoom in or out as much as you want — most browsers let you go down to 25 percent or up to 500 percent of the original size.

If you want to change the default text size for all websites you visit, not just zoom the whole page, look in your browser settings. In Chrome, go to Settings > Appearance and adjust the font size slider. In Firefox, go to Settings > Language and Appearance and change the minimum font size. Safari on Mac has font size controls under Safari > Settings > Accessibility.

Some websites override your browser's text size settings and lock their text to a fixed size. If you cannot make text smaller on a particular site, try zooming the entire page instead of changing just the font size — this usually works even when the site has locked its text.

Changing text size in Microsoft Word and Excel

In Word, select the text you want to shrink, then use the font size dropdown in the toolbar — it usually shows a number like 12 or 14. Click the dropdown and choose a smaller size, or type a custom size. You can also highlight text and press Ctrl+[ (left bracket) to shrink it one size at a time, or Ctrl+] (right bracket) to enlarge it.

In Excel, the same method works: select cells, then change the font size from the toolbar or use Ctrl+[ and Ctrl+]. If you want all new documents to open with smaller default text, change the default font size in your template. In Word, go to Home > Normal > Modify, then change the font size before saving.

If you want to zoom the entire spreadsheet or document to see more on screen at once, use Ctrl+minus to zoom out, just as you would in a browser. This shrinks everything — text, images, and margins — proportionally.

Adjusting text size system-wide on Windows

If you want to make text smaller across your entire computer — in menus, window titles, icons, and notifications — go to Settings > Accessibility > Display. Under "Text size," move the slider to the left to make text smaller or to the right to make it larger. This change affects Windows itself and most programs that follow Windows display settings.

Some older programs do not respect this system-wide setting and keep their own text size. For those, you will need to change the text size within the program itself using its menu or settings.

You can also change the overall scale of everything on your screen — text, icons, and windows — by going to Settings > System > Display and adjusting the "Scale" slider. This is different from text size alone and affects the entire user interface.

Adjusting text size on a Mac

On macOS, go to System Settings > Accessibility > Display and turn on "Larger Accessibility Sizes" or adjust the text size slider. This affects system text in menus and dialogs. For individual applications, use Command+minus to zoom, just as on Windows.

Some Mac programs have their own text size settings in Preferences. Open the process, go to the menu bar, and look for the process name > Preferences or Settings, then search for text size or font size options.

When text is too small to read comfortably

If you find yourself constantly making text smaller or larger, your monitor distance or screen resolution might be the real issue. Sit about 20 to 26 inches from your screen — roughly an arm's length away. If text is still hard to read at that distance, your monitor may be too small for your needs, or your eyesight may have changed.

Before buying a new monitor, try increasing text size instead of decreasing it. Many people assume they need smaller text to fit more on screen, but larger text with more scrolling is often easier on the eyes and faster to read. Experiment with different sizes to find what feels comfortable for a full workday.

If you wear glasses, make sure your prescription is current for computer distance — many people need different glasses for screen work than for reading paper.

Troubleshooting when zoom does not work

If Ctrl+minus does not shrink text in a program, the program may not support zoom. Try using the View menu instead — most applications have a Zoom or Text Size option there. In some programs, it is under Format or Settings.

If a website locks its text size and you cannot zoom it smaller, try using your browser's reader mode if available. Firefox and Safari both have reader modes that strip away the website's design and let you control text size directly. In Firefox, click the book icon in the address bar; in Safari, click the lines icon.

If your entire screen text is too small and keyboard shortcuts are not working, restart your computer. Sometimes display settings get stuck, and a restart resets them.

Frequently Asked Questions

Does zooming text in one browser tab affect other tabs?

No. When you zoom with Ctrl+minus, the change applies only to the current tab. Other tabs keep their original size. If you close the tab and reopen the website later, most browsers remember the zoom level for that specific site and explore it automatically.

Can I make text smaller in PDF files?

Yes. If you open a PDF in your browser, use Ctrl+minus to zoom. If you open it in Adobe Reader or another PDF viewer, look for a zoom slider or use Ctrl+minus there as well. Some PDF viewers also have a "fit to width" or "fit to page" option that automatically shrinks the PDF to fit your screen.

Will changing text size in Windows settings affect my games?

Most games ignore Windows text size settings and use their own display settings. If text in a game is too small, look in the game's graphics or display settings for a UI scale or text size option. Some games do not offer this control.

What is the difference between zoom and text size?

Zoom shrinks or enlarges everything on the page — text, images, and spacing — proportionally. Text size changes only the font size while leaving images and spacing alone. Zoom is faster for making a whole page smaller; text size is better when you want to keep the layout the same but read larger words.

Can I set a different default text size for each program?

Yes, but it varies by program. Most applications remember your last zoom level when you close and reopen them. Some let you set a default in preferences. Word and Excel let you change the default font size in your template, which affects all new documents you create.
