Small text looks most deliberate when it plays a supporting role next to normal text.
- Subtitles. A name in normal letters with a role underneath in small caps, such as ᴡʀɪᴛᴇʀ ᴀɴᴅ ᴛᴇᴀᴄʜᴇʀ, looks like a printed masthead.
- Chapter and section labels. ᴄʜᴀᴘᴛᴇʀ ᴏɴᴇ is a familiar book convention, and Small caps keep it light.
- Footnote marks. A single raised digit after a claim, converted on its own with Superscript, points the reader to a note at the bottom.
- Whispered asides. A short remark in Small caps reads as quieter than the sentence around it.
Remember that Small caps fold upper and lower case into one set. A name such as iPhone or McDonald loses its capital letters when converted, because every letter becomes the same small capital, so use it for words where the capitals do not carry meaning.
For long passages, a different approach is better. Small caps are readable but unusual, and a paragraph of them slows people down. If your aim is a decorative profile, pair one small caps line with a clean, short plain line. The Facebook font generator shows your text in many styles at once if you want to compare before choosing.
