The fastest way to enlarge text on any computer

The quickest method works on almost every computer: hold down the Ctrl key (or Cmd on Mac) and press the plus sign (+) key. Each press makes text larger. To shrink it back, use Ctrl (or Cmd) and the minus sign (−). To reset to normal size, press Ctrl (or Cmd) and 0 (zero).

This keyboard shortcut works in web browsers, email programs, word processors, and most other applications. The change applies only to what you are looking at right now—it does not permanently alter your computer's settings.

If you want text to stay larger every time you use your computer, you will need to change your display settings instead. The steps differ between Windows and Mac, and the location of these settings has moved in recent versions of each operating system.

Key Takeaways

  • Hold Ctrl (or Cmd on Mac) and press the plus key to enlarge text in any open window; each press makes it larger.
  • This temporary zoom works in browsers, email, and most programs, but resets when you close the window or restart the process.
  • To make text permanently larger across your entire computer, change the display scaling in your system settings, not in individual programs.
  • Windows and Mac store these settings in different places, and the exact steps depend on which version of each operating system you have.
  • If you have vision difficulties, both Windows and Mac offer accessibility tools that enlarge text, cursor, and pointer across everything you do.

Making text larger in Windows 10 and Windows 11

Open Settings by pressing the Windows key and typing "settings," then press Enter. In the left sidebar, click System, then click Display.

Under the heading Scale and layout, you will see a dropdown menu labeled Scale. The default is usually 100%. Click the dropdown and choose a larger percentage—125%, 150%, or 175% are common options. Your screen will adjust when ready, and text, buttons, and icons will all grow larger.

If none of the preset sizes feel right, click the dropdown again and select Custom scaling at the bottom. You can then type any percentage between 100% and 500%. After you set a custom size, you may need to restart some programs or sign out and back in for the change to take full effect.

Making text larger on Mac

Click the Apple menu in the top-left corner and select System Settings (or System Preferences on older Macs). Click Displays in the sidebar.

At the bottom of the Displays window, you will see a slider labeled Resolution. Drag it to the left to make everything on your screen larger, including text. The option on the far left says Larger text and produces the biggest change. You can also click Scaled to see numbered size options if you prefer to pick an exact setting.

The change takes effect when ready. Unlike Windows custom scaling, Mac does not usually require you to restart programs.

Using accessibility tools for vision difficulties

Both Windows and Mac include built-in tools designed for people who have trouble reading small text. These go beyond straightforward scaling and can enlarge specific parts of your screen or change how text appears.

On Windows, open Settings, go to Accessibility, and click Magnifier. This tool enlarges a portion of your screen as you move your mouse, letting you zoom in on any area without making everything bigger. You can also go to Accessibility and select Text size to enlarge text in Windows menus and dialog boxes separately from your overall display scaling.

On Mac, click the Apple menu, go to System Settings, click Accessibility, and select Zoom. This lets you enlarge your entire screen or just a portion of it. You can also click Display in the Accessibility menu to increase text contrast or enable other visual adjustments.

Why text size changes do not always work in every program

Some older or specialized programs do not respond to your computer's display scaling settings. If you enlarge your display to 150% but a particular program still shows tiny text, the program may have its own text size controls.

Look in that program's menu for options labeled Preferences, Settings, or View. Many programs have a Font Size or Text Size option buried there. Web browsers almost always have this—in Chrome, Firefox, and Edge, you can use Ctrl (or Cmd) and the plus key, or look in the menu under Settings or Preferences for a zoom option.

If a program has no text size control and does not respond to your system settings, the program may be too old to support modern scaling. In that case, the keyboard zoom shortcut (Ctrl or Cmd plus the plus key) is often your only option.

Adjusting text size in specific programs

Microsoft Word, Google Docs, and most word processors have their own zoom controls. In Word, look for a zoom slider in the bottom-right corner of the window, or go to the View tab and click Zoom. In Google Docs, click View in the menu and select a zoom percentage.

Email programs like Outlook and Gmail also respond to the Ctrl (or Cmd) plus-key shortcut. If that does not work, check the program's Settings or Preferences menu for a text size or display option.

For reading PDFs, most PDF readers (including the one built into Windows and the Preview app on Mac) support the Ctrl (or Cmd) plus-key zoom. Some also have a dedicated zoom menu or buttons in the toolbar.

When to restart your computer after changing text size

On Windows, changes to display scaling usually take effect right away, but some programs may not resize properly until you close and reopen them. If you change custom scaling to an unusual percentage, restart your computer to may support all programs adjust correctly.

On Mac, you almost never need to restart. Changes to display resolution and zoom explore when ready to everything on your screen.

If you change text size and find that some windows or buttons look cut off or misaligned, try restarting the affected program first. If that does not fix it, restart your computer.

Frequently Asked Questions

Will enlarging text on my computer slow it down?

No. Changing display scaling or text size does not affect your computer's speed or performance. It only changes how large things appear on your screen.

Can I make text bigger in just one program without changing my whole screen?

Yes. Use the Ctrl (or Cmd) plus-key shortcut to zoom in that program only. The change stays in effect only while that program is open. Alternatively, look in the program's menu for a dedicated zoom or text size control.

What if I set my display to 175% and now some windows are too big to fit on my screen?

Lower the scaling percentage in your display settings. Try 150% or 125% instead. If a specific program has windows that do not fit, that program may not be designed to work well with high scaling percentages—try using its built-in zoom control instead.

Does changing text size affect printing?

Display scaling does not change what prints. When you print a document, it prints at its original size unless you change the zoom or scaling within that specific program before printing. Always preview your document before printing to see how it will look on paper.

Can I make the cursor or mouse pointer bigger along with the text?

Yes. On Windows, go to Settings, click Accessibility, select Mouse pointer and touch, and adjust the pointer size. On Mac, go to System Settings, click Accessibility, select Display, and look for pointer size options.
