Digits have better small-font coverage in Unicode than letters do — you can get raised, lowered, and circled numbers as plain copy-paste text. Generate them with the superscript generator, subscript generator, or bubble text generator.
This guide covers the three small-number styles and where each fits.
Superscript digits (⁰¹²³)
The smallest option. Complete set 0–9 plus + − = ( ). Used for exponents (x²), footnote markers, and ordinal suffixes (1ˢᵗ). See superscript numbers and exponents.
Subscript digits (₀₁₂₃)
Same size range, sits below the line. Complete set 0–9. Used for chemical formulas (H₂O) and indexed variables (xₙ). See subscript numbers for chemistry.
Circled and small digits (①②③, ⓪)
Circled numbers from the bubble set — larger than super or subscript but distinct, good for lists and rankings. Digits 0–9 all have a circled form.
Which to use
Exponent or power: superscript. Formula or index: subscript. A decorative numbered list or a rank badge in a name: circled. All three copy and paste as plain text and count as one character each.
