How do you change the default paragraph setting for a textbox

[Old Man]

When I open a textbox the paragraph has a setting of 12 point before, even
though this is not the case for the document itself. How do I change this
setting for textboxes so that it changes for all documents I create (ie make
it a default).

When you create a textbox, Word uses the style named Normal to format it. To
force Word to default to a different spacing setting, you would need to
change the formatting of Normal.
