Superscript generator

Superscript is the tiny raised text — ˡⁱᵏᵉ ᵗʰⁱˢ — and subscript is the tiny dropped version, ₗᵢₖₑ ₜₕᵢₛ. Both come from real Unicode characters, so they paste anywhere: a footnote marker in a comment, math-ish or chemistry-ish notation (H₂O, x², that sort of thing), or just a small-text aesthetic on a bio. The thing nobody tells you: Unicode never finished either alphabet. Superscript is missing a few lowercase letters (and most capitals) — they fall back to full size — and subscript is even patchier, covering only a handful of letters. So a word that's all lowercase letters Unicode happens to have will look great; one with the wrong letters or any capitals will look half-broken. If you want consistent small-looking text with a complete alphabet, small caps (also in the dropdown) is the better tool — it just doesn't sit above or below the line.

How to use it

Type in the box on the left. The style you’ve picked on the right updates as you type — no “generate” button. Click Copy and paste it wherever you need. On the home page you can also browse every style in the list below and click any row to load it into the panel.

Where it renders, and where it breaks

Where superscript and subscript render isn't really the issue — they're just characters, and they show up almost everywhere. The catch is internal: the alphabets have holes, so whether your specific word looks right depends on which letters it uses.

App / platform	Where	Status	Notes
Instagram	bio, captions, comments	Works	Displays fine — but any letter Unicode doesn't have a superscript form for will pop back to full size, which can ruin a word. Numbers always work.
TikTok	bio, captions, comments	Works	Same — fine to display, patchy by design for letters.
Discord	messages, nicknames, About Me	Works	Renders everywhere. Small caps reads more cleanly than superscript at nickname size.
X (Twitter)	posts, bio, display name	Works	Fine. The @handle stays plain.
WhatsApp / Telegram	messages, status, About	Works	Works. Subscript digits in formulas render well; subscript letters are very limited.
Math / chemistry notation anywhere	any text field	Works	Superscript and subscript digits are complete — x², H₂O, 10⁶ all come out right. This is the one use where there are no missing-character problems.
Games / usernames generally	in-game names	Partial	Hit-or-miss — partly the filters, partly the missing-letter fallbacks making a name look broken. Small caps is the more reliable small-looking option for names.

All of these are real Unicode characters, not images or font files, so the styling travels with the text wherever you paste it. The catch: a few apps with locked-down fonts will draw some glyphs as empty boxes — that's the receiving app, not the text, and switching styles fixes it. Bold (sans), Small Caps and Full-width render the widest. Checked May 2026; platforms change their font handling constantly, so treat the table below as a strong guide, not a guarantee. The full cross-app compatibility page goes wider.

Examples & use cases

What superscript and subscript are actually good for:

Footnote markers in a comment — A claim followed by ¹ and the source — the superscript digits are complete, so this always looks right, even where there's no real footnote feature.
Math notation — x², n³, 10⁶, E=mc² — superscript digits handle exponents cleanly in any plain text field.
Chemical formulas — H₂O, CO₂, C₆H₁₂O₆ — subscript digits are complete, so formulas come out correct. (Subscript letters are the limited part.)
A small-text bio (with a caveat) — ˡⁱᵗᵗˡᵉ ᵗᵉˣᵗ looks neat — until a word hits a missing letter and that letter jumps to full size. For a whole word or line, small caps (in the dropdown) stays consistent.
Small caps when superscript breaks — If a word comes out with full-size gaps, switch to ꜱᴍᴀʟʟ ᴄᴀᴘꜱ — complete alphabet, reads small and clean, just sits on the baseline instead of above it.

Common mistakes

Don't assume superscript has a full alphabet. It doesn't — several lowercase letters and most capitals have no superscript form, so they stay full size. Subscript is even more limited. For consistent small text, use small caps.
Don't expect it to actually shrink the font size. These are separate characters drawn small — not a size change. Nothing pasted as text can resize text; the app controls that.
Don't put capital letters in superscript and expect them small. Almost no capitals have superscript forms — they'll stay full size. If you need a small-looking capital, that's what small caps is for.
Don't use subscript for general 'small text'. Subscript covers only a handful of letters — it's built for chemical formulas and footnotes, not for styling a bio. Reach for small caps for that.

FAQ

Why are some of my letters full-size in superscript?

Because Unicode doesn't have a superscript version of every letter — several lowercase letters and most capitals just don't exist in that range, so they stay normal size. Subscript is even more limited. There's no fix; it's the character set's gap.

Superscript vs. subscript vs. small caps — what should I use?

Superscript for raised tiny text (footnotes, exponents). Subscript for lowered tiny text (chemical formulas). Small caps when you want a full word to read small and clean with no missing letters — it's the most reliable of the three for general 'small text'.

Can I write H₂O or x² with this?

Yes — the digits all have superscript and subscript forms, so numbers in formulas work well. It's letters where the gaps appear, not numbers.

Does this work in an Instagram bio?

Yes, in bios and captions. Just expect any unsupported letters to pop back to full size, which can ruin the effect — for a clean look across a whole word, small caps is the safer pick.

Why do superscript digits work but superscript letters don't?

Unicode defined a complete set of superscript (and subscript) digits because they're needed for math and chemistry notation, but only a partial set of letters. So numbers in formulas are fine; a word may have gaps.

Is there a superscript capital A, B, C…?

Mostly no. A handful of capital-ish superscript letters exist, but the set is far from complete, so most uppercase letters fall back to full size. If you need small-looking capitals, small caps gives you the whole alphabet.
