Small caps, ALL CAPS, and Title Case all touch capitalisation but read very differently. Small caps is the only one that needs a tool, since it's a Unicode character style — get it from the small caps generator.
This guide compares the three and says when each is the right choice.
How they look and sound
ALL CAPS (LIKE THIS) is loud — full-height capitals read as shouting or high emphasis. Title Case (Like This) capitalises the first letter of each significant word — neutral, used for headings and names. Small caps (ʟɪᴋᴇ ᴛʜɪs) uses capital letterforms shrunk to x-height — quiet, even, refined.
When to use each
ALL CAPS: a single short label or a deliberate shout, sparingly. Title Case: headings, product names, anything that follows standard style rules. Small caps: a bio line, a subtitle, or a byline where you want structure without volume — it signals 'this is a heading' without raising the tone.
Why small caps needs a generator
Capitalisation is just which keys you press; small caps is a different set of characters that no keyboard types directly. A small caps generator does the substitution, and the result copies and pastes like normal text.
Readability
Small caps stays readable at length because every letter is the same height and weight. ALL CAPS gets tiring fast because there are no ascenders or descenders to help the eye. For a full styled bio line, small caps is the more comfortable read.
