To change the font size and / or font for a WSL (windows subsystem for linux) terminal on Windows 10, I was able to do so by doing the following:
- Right click in the top title bar of the terminal window (this is the likely gray part of the window with an orange circle on the left).
- From the menu that appears upon right click, select properties.
- Select Font, and choose the size you’d like (I prefer size 20 for my WSL windows)
- Then select OK (once OK is clicked the windows and the window text should resize to the selected font size).
Hope this helped!
