Dots per inch (DPI) is the physical measurement of number of pixels in a linear inch of a display. DPI is a function of display resolution and size; a higher resolution or a smaller size will lead to higher DPI, and a lower resolution or a larger size will lead to lower DPI. When a display has a higher DPI, pixels are smaller and closer together, so that the user interface (UI) and other displayed content appears smaller than intended.
Windows ensures that everything appears on the screen at a usable and consistent size by instructing applications (including the Windows desktop shell) to resize their content by a scale factor. This number depends on the display DPI as well as other factors that impact the userâ€™s perception of the display. Almost all desktop displays and most current laptop displays are in the range of 95-110 DPI; for these devices, no scaling is required, and Windows sets a scale factor of 100%. However, there are a number of new devices, particularly in the premium laptop and tablet markets, which have higher displays with over 200 DPI. For these devices, Windows sets higher scale factors to ensure that the user experience is comfortably viewable.
You can adjust the display DPI scaling level in Windows 11 to change the size of text, apps, and other items to appear larger or smaller until comfortable to see for you.
When you increase the display DPI scaling level, everything will appear larger on the display.
When you decrease the display DPI scaling level, everything will appear smaller on the display.
The default DPI scaling level is 100% (96 DPI).
This tutorial will show you how to change the DPI scaling level for all or specific displays to make everything appear smaller or larger on the display(s) for your account in Windows 11.
