How To Change Display DPI Scaling In Windows 11

Dots per inch (DPI) is a physical measurement of the number of pixels in a linear inch of a screen. DPI is a function of screen resolution and size; higher resolution or smaller size will result in higher DPI and lower resolution or larger size will result in lower DPI. When the screen has a higher DPI, the pixels get smaller and closer together, so the user interface (UI) and other visible content appear smaller than intended.

Windows ensures that everything displays on the screen at the right size and is usable by instructing applications (including the Windows desktop interface) to resize their content according to the size of the screen. ratio factor. This number depends on the DPI of the monitor as well as other factors that affect the user's perception of the screen. Almost all desktop monitors and most laptop screens these days are in the 95-110 DPI range; for these devices, no scaling is required and Windows sets the scaling factor to 100%. However, there are some new devices, especially in the premium laptop and tablet market, that have taller screens with more than 200 DPI. For these devices, Windows sets a higher scaling factor to ensure a comfortable viewing experience.

You can adjust the display DPI scaling level in Windows 11 to resize text, apps, and other items to display larger or smaller until you're comfortable.

When you increase your monitor's DPI scaling, everything will appear larger on the screen.

When you decrease your monitor's DPI scaling, everything appears smaller on the screen.

The default DPI scaling level is usually 100% (96 DPI), but can vary by display as "recommended".

This guide will show you how to change the DPI scaling level for all or specific monitors to make everything display smaller or larger on the monitor(s) for your account in Windows 11.
