You can make the text (and other things like icons) larger without changing the screen resolution of your monitor or laptop screen. That way, you can make text easier to see and still keep your monitor or laptop set to the best possible resolution.
Open Screen Resolution by swiping in from the right edge of the screen, tapping Search (or if you're using a mouse, pointing to the upper-right corner of the screen, moving the mouse pointer down, and then clicking Search), entering Display in the search box, tapping or clicking Settings, and then tapping or clicking Display.
Choose one of the following:
Smaller - 100% (default). This keeps text and other items at normal size.
Medium - 125%. This sets text and other items to 125% of normal size.
Larger - 150%. This sets text and other items to 150% of normal size. This option appears only if your monitor supports a resolution of at least 1200 x 900 pixels.
Tap or click Apply.
To see the new text size, close all of your apps, and then sign out of Windows. The change will take effect the next time you sign in.
Also, you can change the text size for specific items in Windows, like window title bars or tooltips, without changing the size of anything else on the screen.
Under Change only the text size, choose the item you'd like to change and pick a text size. If you want the text to be bold, select the Bold check box.
You'll see the change the next time you sign in to Windows.
You can also make text appear larger or smaller by changing your screen resolution, but if you're using an LCD monitor or laptop, it's a good idea to set your screen to its native resolution to avoid blurry text. This is the resolution that a monitor or laptop screen was designed to display based on its size. For more info, see Get the best display on your monitor.
If you have a 1080p touchscreen device, you might need to adjust the size of the items on your screen to make sure touch works correctly. By default, some 1080p touchscreen devices show text and other items at 150%, and some of your apps might not work at that size. To fix the problem, follow these steps:
Tap or click Smaller - 100% (default).
Then tap or click Apply.
You can't change the default font or font color used for items in Windows (like window title bars, menus, or tooltips). But you can change the color of your window borders and taskbar, or use a High Contrast Theme to make the items on your screen easier to see. For more info, see Get started with themes.
