Simply run following command on terminal:

gsettings set org.gnome.desktop.wm.preferences titlebar-font 'Ubuntu Bold 11'

Number 11 is default font size for title bar font, I believe you want to adjust their size to your preferred size.

Install unity-tweak-tool:

sudo apt install unity-tweak-tool

After than you can adjust the fonts for the different locations in that tool

You can also change this setting graphically using Tweaks. Install it, if you haven't already, using:

sudo apt install gnome-tweaks

Then open Tweaks → Fonts → change Legacy Window Titles to the desired font and size.
