Welcome to the forum.
If you go to Tools>Options>Document properties>dimensions
you will see all of the settings to change various aspects of dimensions,
text fonts, text heights etc. These settings are tied into the standards selected.
I would set these in your default templates this way they always come in set.
Another thing is for archived type files you can save these settings out to a file
then import these in and it will automatically set everything. Go to Tools>Options>Document Properties>Standards.
I hope this helps you.
