How do I set Arial as my permanent font?

I want Arial to be my permanent font in all documents. I cannot find page set up where I would normally make such changes. How can I accomplish this task? common

Posting answers as wiki may make sense in rare cases. A wiki question won’t.

All the new documents are derived from a default template or from a template created or imported by the user and made the standard subsequently.
Thus: You need to create a template per document class with the preferred fonts and whatever attributes set for the respective styles and make it your standard using the template manager (>Files>Templates>Manage Templates).
Read the guide about templates and make sure to basically understand heritage to be able to do a good job creating templates.

(By the way: Why Arial? It’ so ugly.)

For some reason it is easier for me to read. Maybe it has to do with my astigmatism. I will do as you suggested and I thank you for taking the time to answer the question.

All done Lupp!

If you generally prefer fonts without serifs for personal reasons, that’s ok, of course, as every personal decision. A little problem may arise for your templates because headings are set to such a font by default, this way distinguishing them from ordinary text.

A very personal remark by Lupp: There are many fonts without serifs, but a great many of these again are mimicking (somehow) the wrongly famous Helvetica. Arial is a specific example of this class. They all suffer from the absurd idea that abandoning serifs should also do away with curved lower ends - of lower case letters in specific for distinction, and that roughly straight lines should be represented by rectangular areas . For the sake of caprice the principle then is applied to “u” and “l” but not to “a” (which is a monster sui generis) and “t”. Just write “Ilias” (the story of the Troian war) in Arial to verify my criticism. Copy “tlIlt” in Arial and convert it then to serifs. Fun!
