Increase Ubuntu high resolution font size

I recently got a new laptop with Ubuntu 17.10 and a 14" screen. The screen is awesome and allows an awesome resolution of 1920 x 1080. However, this caused the fonts to appear very small. This small font issue was observed in,

• Titles of the windows
• The font  in general in several applications
• Browser, in my case Firefox

You can do away with all the trouble by simply choosing a lower resolution. But, if you want the higher resolution minus all the font troubles, read ahead.



After several trials and techniques, I finally found solutions that worked for me.

• Window Titles
• Settings -> Universal Access -> Large Text
  This would increase your font size of window titles and the OS UI.
  
• Applications
• Several applications will by default show small fonts. Adjust them as per your liking using their respective preferences.
• Kate Editor ( Version 17.04 )
• Settings -> Configure Kate -> Fonts & Colors -> Font
  Choose the font size you prefer.
• Konsole ( Version 17.04 )
• Settings -> Edit Current Profile (or whichever you prefer) -> Appearance -> Font
  
• Browser ( Firefox / Version 56)
• My browser was the one giving most of the trouble, I had to zoom in everytime I loaded a page. The solution is to open
  about:config ( Type this in the URL bar of your new tab ) in your firefox. Search for 'layout.css.devPixelsPerPx'. By default it is set to '-1'. I changed it to 1.3 and that works best for me. Change the values and choose the one that best matches your requirements.
