Linux font configuration issue

Im using Linux Mint 4.15.0-20-generic / Cinnamon 3.8.8

I have an issue where all of the fonts on the sidebars and pop up windows are too large and unable to see the last half of the word. 
Here is a link to an image on my googe drive  showing the problem:  drive.google.com/open?id=1nLqf6O0JM8TbSpwedTIzPaT58zna-UfC
Where is the font size referenced in the program and how could I change it?

Thank you. 
Jay
