The fastest way to enlarge text on any computer

Hold Ctrl and press the plus key (+) on your keyboard. Each press makes text larger. To make it smaller again, hold Ctrl and press the minus key (−). To reset to normal size, hold Ctrl and press 0 (zero).

This method works in most web browsers, email programs, and document editors. It enlarges only what you are looking at right now — the next time you open that program or website, it returns to its default size unless you change it again.

If you want text to stay larger every time you use your computer, you will need to change your system-wide settings instead. The steps differ between Windows and Mac.

Key Takeaways

  • Ctrl + plus key enlarges text in any open program; Ctrl + minus key shrinks it; Ctrl + 0 resets it to normal.
  • Windows lets you enlarge all text on your screen through Settings > Accessibility > Display, which affects everything you see.
  • Mac users can increase text size in System Settings > Accessibility > Display, or use the Zoom feature to magnify the entire screen.
  • If you use a web browser often, you can set a permanent zoom level for each website so it stays enlarged the next time you visit.

Making text larger in Windows

Open Settings by pressing the Windows key and typing "settings", then press Enter. Click Accessibility in the left sidebar. Under the Display section, you will see a slider labeled Text size. Drag it to the right to make all text on your screen larger — this affects menus, buttons, window titles, and most programs.

The text size slider usually goes from 100% (normal) to 225% (very large). Changes take effect right away. Some older programs may not respond to this setting, but most modern software will.

If you want to enlarge only the text in a specific program, use the Ctrl + plus key method instead. That is faster and does not change your system settings.

Making text larger on a Mac

Click the Apple menu in the top left corner and select System Settings. Click Accessibility in the sidebar. Under Display, you will see a slider for Text size. Drag it to the right to enlarge text throughout your system.

If you want to magnify your entire screen rather than just make text bigger, stay in Accessibility and click Zoom. Turn on the zoom feature and use the keyboard shortcut Option + Command + 8 to toggle it on and off. You can also adjust how much the screen magnifies by changing the zoom level in the same menu.

Like Windows, the text size change affects most programs when ready. Older or specialized software may not respond to the setting.

Permanent zoom for websites you visit often

If you read the same websites regularly and want them to stay enlarged, most browsers let you set a permanent zoom level for each site. In Chrome, Firefox, Edge, or Safari, use Ctrl + plus key (or Command + plus on Mac) to enlarge the page, then close the browser. The next time you visit that same website, it will open at the enlarged size you set.

This works because your browser remembers the zoom level for each individual web address. If you visit a different website, it will open at its normal size unless you have also enlarged that one.

To reset a website back to normal size, visit it and press Ctrl + 0 (or Command + 0 on Mac).

When text stays small no matter what you do

Some programs ignore your system text size settings. This happens most often with older software or specialized tools that set their own display rules. If Ctrl + plus key does not work, try right-clicking inside the program window and looking for a menu option like "Zoom", "Text Size", or "Display Settings".

If that does not appear, check the program's main menu — usually under File, View, or Edit. Many programs hide their zoom controls there. If you still cannot find it, the program may not support text enlargement, and you may need to use your operating system's built-in magnifier tool instead.

On Windows, search for "Magnifier" in Settings and turn it on to magnify a portion of your screen. On Mac, the Zoom feature in Accessibility does the same thing.

Using your computer's magnifier tool

Both Windows and Mac include a magnifier that enlarges a section of your screen, useful when text size adjustments are not enough. On Windows, press the Windows key and type "Magnifier", then press Enter. A small window appears showing a magnified view of whatever is under your cursor. You can adjust the magnification level from 100% to 300%.

On Mac, go to System Settings > Accessibility > Zoom and turn on the feature. Use Option + Command + 8 to toggle it on and off, or Option + Command + equals to zoom in and Option + Command + minus to zoom out.

The magnifier is slower to use than straightforward enlarging text, because you have to move it around to see different parts of your screen. Use it as a backup when text size settings do not work.

Frequently Asked Questions

Does enlarging text on my computer slow it down?

No. Changing text size or using the magnifier does not affect your computer's speed or performance. It is purely a display setting that changes how large things appear on your screen.

Will my text size changes stay if I restart my computer?

Yes, if you changed the system-wide text size in Settings or Accessibility. Those changes are saved. If you used Ctrl + plus key in a single program, the change is lost when you close that program.

Can I make text larger on just one monitor if I have two?

System-wide text size changes affect all your monitors at once. To enlarge text on only one monitor, use Ctrl + plus key in individual programs instead, or use the magnifier tool on that monitor only.

What if the text is still too small after I enlarge it?

Try combining methods: enlarge the system text size, then use Ctrl + plus key in the specific program you are using, then use the magnifier tool if needed. You can layer these adjustments for maximum enlargement.

Does font size enlargement work the same way on tablets and phones?

The concept is the same, but the steps are different. Tablets and phones have their own accessibility settings in their operating systems. On an iPad or iPhone, go to Settings > Accessibility > Display & Text Size. On Android, go to Settings > Accessibility > Display and Text.
