This tutorial will show you how to increase or decrease text size across the system for your account in Windows 11.
You can change the text size that appears throughout Windows and your apps without having to change the overall DPI scaling level of your system.
Changes to the text size are saved to the registry keys and values below.
Shell Icon Size
Open Settings (Win+I).
Click/tap on Accessibility on the left side, and click/tap on Text size on the right side. (see screenshot below)
Adjust the Text size slider to the percentage you want, and click/tap on Apply. (see screenshot below)
The default text size is 100%.
The text size in the Text size preview box will change as you adjust the slider to see a preview of the text size before you apply it.
When finished, you can close Settings if you like.
