Create aesthetic bio text that fits within character limits and looks stunning on all smartphones.
The same styled line has to fit different budgets. Instagram: 150 characters, emoji count two. TikTok: 80 characters. X: 160. Discord: the About Me is 190. LinkedIn headline: 220. WhatsApp About: 139. Threads: 500. Styled letters count one each on all of them; frame symbols add their count. The strategy that works across all of them is a short styled signature (a name or one phrase, 15 to 25 characters) followed by plain text that carries the searchable words. That fits TikTok's 80 with room and leaves most of the budget on the others.
Each platform sets its bio in a different typeface and size, and a style that reads well in one can fail in another. TikTok's bio font is light, and small caps and sans-serif bold read as deliberate against it. Instagram's is regular weight and mid-size, and takes script for a single line. X's is small and dense, and wants structural styles only. Discord's About Me is roomy and takes almost anything. The phone icon on each row previews Instagram, Discord and X at their real sizes. For a signature that has to work everywhere unchanged, sans-serif bold with no frame is the choice that never fails.
TikTok, at 80 characters. A styled signature of 15 to 25 characters plus one plain line fits it, and the same text then fits Instagram (150), X (160) and Discord (190) with room.
Sans-serif bold with no frame. It renders everywhere, stays legible at every platform's bio size, and reads as emphasis rather than as a different font.
Not on Instagram, where emoji count as two characters and styled letters as one. On most other platforms both count as one. The count under each result here counts styled letters and frame symbols only.
