Allow to change the default font size in editor.

What problem does this address?

In gutenberg Editor it would be nice to have capability to change the default font size.

What is your proposed solution?

It would be great to add_action or add_filter in functions.php for this small enhancement.

Thank you for submitting the issue.
You can change the default font size in the following way:

On Classic Theme

Register a style sheet describing the following style via add_editor_style().

body {
  font-size: 20px;
}

On Block Theme

You can configure this in theme.json.

{
  "version": 2,
  "styles": {
    "typography": {
      "fontSize": "20px"
    }
  }
}
