mimicWhich case to use where
| Case | Good for | Watch out |
|---|---|---|
| UPPERCASE | A short hook or on-screen word | Hard to read in long captions |
| Title Case | YouTube titles, headers | Small words (a, of, the) stay lowercase |
| Sentence case | Captions and descriptions | Fixes ALL-CAPS text pasted from elsewhere |
| aLtErNaTiNg | Mocking or meme tone | Not for anything serious |
| Small caps | A styled name or short label | Unicode look-alikes: screen readers and search may not read them |
How it works
Upper, lower, title and sentence case change ordinary letters. Small caps swap each letter for a Unicode character that looks like a small capital, which is why it survives pasting into apps that don't let you pick a font.
With “leave hashtags alone” on, #tags, @mentions and links keep their exact spelling, so a #SkinCare tag doesn't turn into #SKINCARE.
Worked example
Input: “this serum changed my morning routine. here's why i'm never going back #skincare”
Title Case: “This Serum Changed My Morning Routine. Here's Why I'm Never Going Back #skincare”
Sentence case: “This serum changed my morning routine. Here's why I'm never going back #skincare”
Small caps: “ᴛʜɪꜱ ꜱᴇʀᴜᴍ ᴄʜᴀɴɢᴇᴅ ᴍʏ ᴍᴏʀɴɪɴɢ ʀᴏᴜᴛɪɴᴇ…”
Questions
How do I get small caps on Instagram or TikTok?
Convert your text here and paste it. The letters are Unicode characters, so they show without a special font.
Are small caps bad for accessibility?
They can be. Screen readers may read them as symbols, so use them for a word or two, not a whole caption.
Does Title Case capitalise every word?
No. Short words like a, and, of and the stay lowercase unless they start or end the title.
Will it change my hashtags?
Not with “leave hashtags, mentions and links alone” on, which is the default.
