Type once, see your character and word count against 8 platform limits simultaneously. No signup, works entirely in your browser.
What counts as a character? Letters, numbers, spaces, punctuation, and emoji all count as characters. Most platforms count using UTF-16 code units, which means a simple emoji is usually 2 characters and a complex emoji with modifiers can count as 4 or more, even though it displays as a single image.
Every platform sets its own character limit based on how that field is used. Twitter/X allows 280 characters in a post because tweets are meant to be scannable at a glance. Instagram's 150-character bio limit forces a tight, curated profile summary. TikTok's 80-character bio is the shortest of the major platforms, reflecting its video-first design where the bio is secondary to content.
These limits also change over time as platforms redesign their profile pages, so treat the numbers on this page as accurate estimates and always confirm the exact limit in the platform's own interface before finalizing important text.
If you are pasting fancy Unicode text from the Font Generator, most styled characters count as exactly one character each, the same as plain text, so styling your bio does not cost you extra room against these limits.
