Change Default Font for Google Docs
Do you have a favorite font you like to use instead of the Google Doc Default font - Arial, size 11? If so, here is a simple way to change the default font so that all new documents will be set to the one you prefer.
- Type in some text
- Highlight the text and choose the font, size, format, etc. you want to make the default
- Keep the text highlighted and click on Normal text (in toolbar)
- Click arrow next to Normal text and choose Update ‘Normal text’ to match

- With the text still highlighted go back to the Normal text menu scroll to the bottom and choose options and Save as my default styles

Now all new documents or presentations you create will use this font unless you change the default option again.
