Editors should avoid manually inserting large and small font sizes into prose. Increased and decreased font size should primarily be produced through automated facilities such as headings or through carefully designed templates. Below is one list of font sizing templates that have been tested and are available if needed:

Example: {{ big|Will make the text here larger}} renders as: Will make the text here larger

Also, works with Unicode and IPA. Example: {{ big|{{unicode|ὡ}}}} renders as: ὡ
