The fastest way to change font size depends on what you're looking at

If you want larger text on your screen right now, use your keyboard: hold Ctrl and press the plus key (+) to make text bigger, or Ctrl and minus key (−) to make it smaller. This works in most web browsers, email programs, and document editors. To reset to the original size, press Ctrl and 0 (zero).

If you want to change the default font size across your entire system — so all text appears larger when you start your PC — you'll go through Windows Settings instead. The path and the options available depend on whether you're running Windows 10 or Windows 11, and whether you want to enlarge just text or your whole screen.

Key Takeaways

  • Press Ctrl and the plus key together to enlarge text in any open program, and Ctrl and minus to shrink it.
  • Windows Settings lets you change the default text size system-wide, but the steps differ between Windows 10 and Windows 11.
  • Display scaling enlarges everything on your screen at once — text, icons, buttons — rather than text alone.
  • Some programs like Microsoft Word have their own font size controls in the toolbar that override system settings.

Enlarging text in a single program using your keyboard

The quickest fix for text that's too small is the keyboard shortcut. Hold down Ctrl and tap the plus key (on the main keyboard or the numeric keypad) as many times as you need. Each press makes the text one size larger. You'll see the change happen when ready in most programs.

To go back to normal size, press Ctrl and 0 (zero). To make text smaller, use Ctrl and the minus key. This shortcut works in web browsers like Chrome, Edge, and Firefox; in email programs like Outlook and Gmail; and in document editors like Word and Google Docs. It does not work in every program — some older or specialized software may ignore it — but it's worth trying first.

Changing default text size in Windows 10

To make text larger by default across your whole system in Windows 10, open Settings by pressing the Windows key and typing "settings," then press Enter. Select Ease of Access from the left menu, then click Display.

Under "Make text bigger," you'll see a slider. Move it to the right to enlarge text system-wide. The slider offers three sizes: 100% (normal), 125%, and 150%. After you adjust it, you may need to sign out and sign back in, or restart your PC, for the change to take effect everywhere.

This setting changes the size of text in menus, dialog boxes, and system labels, but not always in individual programs. Some applications like Word have their own text size controls that override this setting.

Changing default text size in Windows 11

Windows 11 moved this setting. Open Settings (Windows key + I), then go to Accessibility in the left menu. Click Text size.

You'll see a slider labeled "Text size." Drag it to the right to enlarge text, or to the left to shrink it. Windows 11 offers more granular control than Windows 10 — you can adjust the size in smaller increments rather than jumping between three fixed sizes. The change takes effect when ready in most places, though you may need to close and reopen some programs to see the difference.

Using display scaling to enlarge everything at once

If you want to enlarge not just text but also icons, buttons, and images across your entire screen, use display scaling instead of text size. This is useful if you have a high-resolution monitor and everything feels cramped.

In Windows 10, go to Settings > System > Display. Under "Scale and layout," you'll see a dropdown menu showing your current scaling percentage (usually 100%). Click it and choose a larger percentage — 125%, 150%, or higher depending on your monitor.

In Windows 11, open Settings > System > Display. Scroll down to "Scale" and click the dropdown to choose a new percentage. After you change the scaling, you may need to restart your PC for all programs to display correctly.

Changing font size in Microsoft Word and other Office programs

Microsoft Word, Excel, and Outlook have their own font size controls that work independently of your system settings. In Word, open any document and look at the toolbar near the top. You'll see a box showing a number (usually 11 or 12) — this is the current font size in points.

Click that box and select a larger number from the dropdown list, or type a custom size. This changes only the selected text in that document, not the default for all future documents. To change the default font size for all new Word documents, select the text you want to change, then go to Home > Styles > right-click Normal > Modify > change the font size > OK.

Excel and Outlook work similarly — find the font size box in the toolbar and click it to choose a new size.

Changing font size in web browsers

Most web browsers let you adjust text size on individual websites without changing your system settings. In Chrome, Edge, and Firefox, the keyboard shortcut Ctrl and plus works on any webpage. You can also access this through the menu: click the three-dot menu icon in the top right, look for a zoom or text size option, and adjust from there.

Some browsers also let you set a default zoom level for all websites. In Chrome, go to Settings > Appearance and look for "Page zoom." In Edge, go to Settings > Appearance > Zoom. These settings explore to every website you visit unless you override them on a specific site.

Frequently Asked Questions

Why does text look blurry after I change the font size?

Blurry text usually happens when you change display scaling and don't restart your PC afterward. Some programs cache the old scaling information and need a fresh start. Restart your computer and the blur should disappear. If it persists in one specific program, try closing and reopening that program alone.

Can I make text bigger in Windows without changing the whole display?

Yes. Use the text size slider in Accessibility settings (Windows 11) or Ease of Access (Windows 10) rather than display scaling. This enlarges text in menus and system labels without scaling icons and buttons, which some people find clearer. Individual programs like Word still have their own font size controls too.

What's the difference between font size and display scaling?

Font size changes only text. Display scaling enlarges everything — text, icons, buttons, images — proportionally. Scaling is useful if your monitor is very sharp and everything feels tiny; text size is better if you want larger words but don't mind smaller icons.

Will changing font size affect how my documents print?

It depends. If you change the text size in a document itself (like in Word), the printed version will reflect that change. If you change only your system text size or display scaling, the document will print at its original size. Always preview your document before printing to see what will actually come out.

How do I change font size in Notepad or other text editors?

In Notepad, go to Format > Font and choose a new size from the dialog box. In other text editors, look for a Format or Edit menu with a Font option. The keyboard shortcut Ctrl and plus may also work depending on the program.
