The quickest way to change font size on Windows 10

Windows 10 gives you three main ways to make text larger or smaller: you can scale everything on your screen at once, change just the text size in specific programs, or adjust the font size in individual applications. The fastest route for most people is the display scaling setting, which enlarges all text, icons, and windows together. This lives in Settings under System > Display, and you can jump there in seconds.

If you only want to change text in one place—like your email or web browser—you can adjust that program's own font settings instead. This leaves everything else on your screen the same size. The method varies by program, but most have a font or text size option in their View menu or settings.

Key Takeaways

  • Display scaling in Settings > System > Display enlarges everything on your screen at once, and you can choose from 100%, 125%, 150%, or 175%.
  • You can also make text larger without scaling everything else by going to Settings > Ease of Access > Display and turning on "Make text bigger."
  • Individual programs like Microsoft Edge, Outlook, and Notepad have their own font size controls, usually found in the View menu or settings.
  • If text is blurry after scaling, restart your computer or the program that looks blurry—Windows sometimes needs to refresh to display scaled text clearly.

Scaling your entire display to make everything larger

Display scaling is the most common way to enlarge text across your whole screen. Open Settings by pressing the Windows key and typing "settings," then select Settings from the results. Go to System, then Display. Under "Scale and layout," you will see a dropdown menu that currently shows a percentage—usually 100%.

Click that dropdown and choose 125%, 150%, or 175%. The higher the number, the larger everything becomes. Windows will ask you to sign out and back in for the change to take full effect, though you will see the change when ready on most programs. After you sign back in, all your text, icons, and windows will be larger.

If none of the preset options feel quite right, you can also create a custom scaling percentage. In the same Display settings, look for "Advanced scaling settings" at the bottom of the page. This lets you set any percentage between 100% and 500%, though very high numbers can make some programs look blurry or behave oddly.

Making only text larger without scaling everything

If you want text to be bigger but you do not want icons and windows to grow, use the text-only enlargement feature. Go to Settings > Ease of Access > Display. Toggle on "Make text bigger." A slider will appear below it—drag it to the right to increase text size, or to the left to decrease it.

This setting affects text in Windows menus, dialog boxes, and some programs, but not everything. Web browsers, for example, usually ignore this setting and use their own font controls instead. After you change it, you may need to restart some programs or sign out and back in to see the change everywhere.

Changing font size in Microsoft Edge and other web browsers

To make text larger in Microsoft Edge, press Ctrl and the plus sign (+) key together. Each time you press it, the text gets bigger. Press Ctrl and the minus sign (−) to make it smaller. Press Ctrl and 0 (zero) to return to the default size. These shortcuts work in most web browsers, including Chrome and Firefox.

You can also adjust text size in Edge through the menu. Click the three horizontal lines (menu button) in the top right corner, then select Settings. Go to Appearance, and under "Zoom" you can set a default zoom level for all websites. This zoom level will stay the same every time you open Edge, even after you restart your computer.

Adjusting font size in Outlook, Word, and other Office programs

In Microsoft Outlook, Word, and Excel, you can change font size in two ways. The quickest is to select the text you want to change, then look for the font size box in the toolbar—it usually shows a number like "11" or "12." Click it and choose a larger size, or type a custom size.

To change the default font size for all new emails in Outlook, go to File > Options > Mail > Stationery and Fonts. Select the font you want to change, click Font, and choose a new size. This will explore to all new messages you write, though it will not change the size of emails you receive.

Fixing blurry text after changing font size

Sometimes after you change the display scaling, text looks blurry or fuzzy. This usually happens because Windows has not fully refreshed the display yet. The simplest fix is to restart your computer. If only one program looks blurry, close that program completely and open it again.

If text is still blurry after restarting, go back to Settings > System > Display and check that your scaling percentage matches your monitor's native resolution. If you are using an older monitor or an unusual resolution, try scaling back to 100% or 125% to see if that clears it up. You can also try right-clicking the blurry program, selecting Properties, then Compatibility, and checking "Disable fullscreen optimizations."

When to use scaling versus individual program settings

Use display scaling when you want everything on your screen to be larger—text, icons, buttons, and windows all together. This is the best choice if you have trouble reading small text everywhere, or if you have a high-resolution monitor that makes everything look tiny.

Use individual program font settings when you only need text larger in one place. For example, if you read a lot of email but your other programs are fine, adjust Outlook's font size instead of scaling your whole display. This keeps your screen organized and prevents some programs from looking stretched or awkward.

Frequently Asked Questions

Will changing font size affect how programs look or work?

Display scaling can occasionally cause programs to look stretched or have buttons in odd places, especially older programs. Text-only enlargement and individual program font settings rarely cause problems. If a program looks wrong after scaling, try lowering the scaling percentage or using text-only enlargement instead.

Can I set different font sizes for different monitors?

Windows 10 allows per-monitor scaling if you have multiple monitors connected. In Settings > System > Display, select each monitor and set its scaling separately. However, this can sometimes cause programs to look blurry when you move them between monitors, so test it before relying on it.

What is the difference between scaling and zoom?

Scaling enlarges everything on your screen at the system level, including icons and windows. Zoom in a web browser or program only makes the content in that program larger. Scaling affects your whole display; zoom affects only what you are looking at right now.

Why does text look blurry on my high-resolution monitor?

High-resolution monitors sometimes display text too small by default. Windows 10 tries to scale automatically, but it does not always guess right. Go to Settings > System > Display and try increasing the scaling percentage to 125% or 150%. If text still looks blurry, your monitor may need a driver update from the manufacturer.
