Change font size in Windows 10 and 11

The fastest way to enlarge text across your entire screen is through the Display settings. Open Settings by pressing the Windows key and typing "Settings", then select it. Go to System, then Display. Under "Scale and layout", you will see a dropdown that says "Scale" — this is usually set to 100%. Click it and choose 125%, 150%, or 175% to make everything larger: windows, menus, text, and icons all grow together.

If you want text to be larger but do not want to scale the whole display, use the "Text size" slider on the same Display settings page. This affects only text in menus and dialog boxes, not web pages or documents. Drag the slider to the right to increase it, then click explore. You may need to sign out and back in for the change to take effect.

For web browsers specifically, you can change font size without touching your system settings. In Microsoft Edge or Chrome, press Ctrl and the plus key (+) together to zoom in. Press Ctrl and minus (−) to zoom out. Ctrl and 0 (zero) returns to the default size. This change applies only to that browser tab and stays until you change it back.

Change font size on Mac

On macOS, go to System Settings (or System Preferences on older versions) and click Accessibility. Select Display on the left side. You will see a slider labeled "Text size" — drag it to the right to enlarge text in menus, dialog boxes, and system windows. This does not affect the size of text in documents or web pages, only the operating system itself.

To make text larger in Safari, press Command and the plus key (+) together. Command and minus (−) makes it smaller. Command and 0 (zero) resets it. This zoom applies only to the current tab and the setting stays until you change it.

If you use an external monitor, you can also change the resolution to make everything appear larger. Go to System Settings, click Displays, and select a lower resolution from the dropdown. Lower resolution means larger text and icons, though the image may look slightly less sharp.

Key Takeaways

  • On Windows, open Settings > System > Display and use the Scale dropdown to enlarge everything on your screen at once.
  • The Text size slider in Windows Display settings makes only menu text larger, not web pages or documents.
  • In any web browser, press Ctrl and plus (+) to zoom in on text and images; Ctrl and 0 resets to default.
  • On Mac, go to System Settings > Accessibility > Display and drag the Text size slider to enlarge system menus and dialog boxes.
  • Lowering your monitor resolution makes all text and icons larger, though the image sharpness may decrease slightly.

Change font size in Microsoft Word and Google Docs

In Microsoft Word, select the text you want to enlarge by clicking and dragging across it. At the top of the window, you will see a box showing the current font size — usually 11 or 12 points. Click that box and type a larger number, or click the dropdown arrow next to it and choose from preset sizes. You can also select all text in the document by pressing Ctrl+A, then change the size for the entire page at once.

In Google Docs, the process is the same. Click into the document, select the text you want to change, then click the font size dropdown in the toolbar (it shows a number like 11 or 12). Choose a larger size from the list, or type a custom number. If you want all new documents to start with larger text, change the size before you start typing, or select all text and change it, then use File > Save as default to lock in that size for future documents.

Change font size in email programs

In Gmail, open any email and look for the zoom controls in the top right corner of the message — they look like a magnifying glass with plus and minus signs. Click the plus sign to enlarge the text in that email. This zoom applies only to the current message. To change the default size for all emails you read, use your browser zoom instead: press Ctrl and plus (+) in Chrome or Edge while viewing Gmail, and the change will stick.

In Outlook on the web, use the same browser zoom method: Ctrl and plus (+) to enlarge, Ctrl and minus (−) to shrink. In Outlook desktop software, go to File > Options > Accessibility and look for text size or zoom settings. The exact location varies by Outlook version, so if you do not see it there, search the Options menu for "zoom" or "text size".

Change font size in PDF readers

If you are reading a PDF in your web browser, use the browser zoom: Ctrl and plus (+) to enlarge. Most browsers also show zoom controls directly in the PDF toolbar at the top of the page — look for a magnifying glass icon or percentage display. Click the plus button or type a larger percentage to enlarge the text.

In Adobe Acrobat Reader (the free desktop process), open a PDF and press Ctrl and plus (+) to zoom in, or use the zoom dropdown in the toolbar. You can also go to View > Zoom and choose a preset size like 125% or 150%, or type a custom percentage. The zoom setting applies only to the current PDF and does not change the file itself.

Troubleshooting when text does not get larger

If you changed the Windows Scale setting and text did not get larger, you may need to restart your computer for the change to take effect. Some older programs do not respond to the Scale setting and will stay at their original size — in that case, use browser zoom or document-level zoom instead.

If you are using a very high-resolution monitor and text still looks small even at 175% scale, try lowering your display resolution instead. Go to Settings > System > Display > Advanced display settings and select a lower resolution from the dropdown. This makes everything larger but may make images look slightly less sharp.

On Mac, if text in an process does not get larger when you adjust the system Text size slider, that process may not support the accessibility setting. Try using the process's own zoom feature instead — most programs have a View menu with zoom or text size options.

Frequently Asked Questions

Will changing the font size affect how my documents print?

It depends on what you changed. If you used browser zoom or document zoom, the printout will reflect that size. If you changed only the Windows Scale setting, documents in Word or Google Docs will print at their original size because the document itself did not change. To make a document print larger, change the font size within the document itself, not the system scale.

Can I make text larger in only one program, not the whole screen?

Yes. Use the zoom feature built into that program instead of changing your system scale. Most programs have a View menu with zoom or text size options. Web browsers let you zoom with Ctrl and plus (+). Word and Google Docs have font size dropdowns in the toolbar. This way, only that program shows larger text.

What is the difference between Scale and Text size in Windows Display settings?

Scale enlarges everything on your screen — windows, menus, text, and icons all grow together. Text size makes only the text in menus and dialog boxes larger, leaving icons and window sizes unchanged. Use Scale if you want everything bigger; use Text size if you want only text to be larger.

Does zooming in a web browser make the page load slower?

No. Zooming is a display-only change that happens on your computer after the page loads. It does not affect how fast the page loads or how much data it uses. You can zoom in and out as many times as you want without any performance impact.

If I change my monitor resolution to make text larger, will it affect my gaming or video watching?

Lower resolution can affect both. Games may run faster at lower resolution but look less sharp. Videos will appear larger but may look pixelated if the resolution is too low. For gaming or video, it is usually better to use zoom in your browser or process instead of changing the system resolution.
