Re: "How to set a default custom font size for mail message composition"
In the Mail app: Click "Mail" in the top menu > choose "Settings" > "Fonts and Colours"
Select the font, and font sizes, that you want to use.

Note that anything you set here is only a suggestion to the mail recipient. You can set your email in 128pt Comic Sans if you want, but there's nothing that says the recipient has to see it that way. Their mail client may be set to view only a plain text version of the email, or may override your font choices.
