In draw.io how can I change the default font to use? Whenever I drag an item the default font is Helvetica, 17.

The font defaults to whatever the last font set on a cell is. Change the font family and font size on a cell and that will become the default.

To clear default styling, ensure nothing is and click "clear default styling" in the right hand format panel.

The diagram format panel in draw.io


Right click on a a shape e.g. box which has the text font as You wish to be as a default font, then in the "format pane" (Ctrl-Shift-P if You don't see it), from the tabulators "Style", "Text", "Arrange" select "Style", then click on "Set as Default Style" at the bottom! Good luck


Right click on a shape with text formatted as you need, select "Set as Default Style". Next element will have that style.


you can go customize the fonts in draw io by going onto the right and go in change fonts and put a random number for a random font
