Set outline thickness for BBText

I can add an outline to my BBText using this:

[outline=white]This text has a white outline[/outline]

But the thickness/size of the outline seems quite large:


Is there a way to define the outline size to make it smaller?

Hi I think is not possible to set the size, one thing I do to avoid this is just to add Effect Outline to the BBText so this way I can change the outline size


Ah, nice! Thanks for that suggestion. It seems to work well.
