For a long time, I wished there is a simple way to increase font size in Windows so that it will be a bit easy on my eyes. Sure, we can increase font size using some registry tricks but that is not user-friendly or viable in the long run. That all changes with the October 2018 update. Among all the other new features, you can now enlarge system font size in Windows 10 by simply dragging a slider in the PC settings app. No need for any tricky registry changes.
The good thing is, once you set font size it will be applied system-wide. System, first-party, and third-party apps will have proportionally increased font size, as long as the apps are using system font settings. This is completely different from DPI scaling which increases the size of everything on your screen. The new option will only increase the font size. Without further ado, let me show you how to increase system font size in Windows 10.
Check your Windows 10 version:
To increase system font size in Windows 10, you should have October 2018 update (v1809) or higher installed on your machine. If you don't know, you can verify that easily by checking the Windows version number. The simplest way to know what version of Windows you are using is to use a run command. Press Win + R, type winver and press Enter. In the About Windows window, see the second line. It should say "Version 1809" or higher. You can safely ignore the OS Build number. Unlike the version, the OS Build number will change every time you install a Windows update.
Increase Font Size in Windows 10 Using PC Settings App
You can increase Windows font size using the Ease of Access page in the PC settings apps.
1. First, open PC Settings app by pressing the keyboard shortcut Win + I. Now, go to the "Ease of Access" page.
2. In the ease of access page, select "Display" on the left panel. On the right panel, you will see a new option called "Make text bigger". Under that, simply drag the slider to increase font size.
3. Helpfully, the settings app will show a preview of the font size. Once you have the desired font size, click on the "Apply" button. Windows will instantly apply the new font size to your entire system.
Personally, I try to keep around 70 centimeters to 80 centimeters distance between me and my computer screen. For that distance, 110% text size looks just perfect. But your mileage may vary depending on the screen size and resolution. So, I encourage you to try different font sizes to find the perfect fit for you. Generally, if you have vision problems or for elderlies, I recommend using around 125% to make reading text easier on your eyes.
Though you can see the changed font size across Windows almost instantly, you might want to restart applications or the Windows system to apply the new font size properly. This because the applications that are working in the background cannot be updated with the new font size while they are being used.
Change Font Size Back to Normal (Decrease Font Size)
To revert back to default text size in Windows, just drag the slider all the way back to left (100%) and you are good to go. Again, restart your system to apply the changes system-wide.
Hope that helps. Let me know what font size you are using for Windows system font and to what size you've increased the system font in Windows 10. Also, check out how to change OEM information in Windows and how to delete clipboard history in Windows 10.
