+Using a DE is pretty straightforward but you might be out of luck if you use something like dwm.

+Find correct DPI of your display currently used by X server
+```bash
+xdpyinfo | grep -B2 resolution
+```
+
+This si probably the correct value. If not, you can calculate it by converting your screen size to inches and dividing the resolution by display length.
+```bash
+xrandr | grep -w connected
+```
+
+{{% center %}}
+{{% figure src="/img/xrandr.png" title="The output on my machine" alt="Output of the last command" %}}
+{{% /center %}}
+
+The above block spits your screen resolution and physical size. Now divide it by display length in inches.
+
+Create/modify the file `~/.Xresources` and append the following line (replace 96 with your DPI)
+```
+Xft.dpi: 96
+```
+and have it processed by the startup file (like .xinitrc)
+```
+xrdb -merge ~/.Xresources
+```
