Instagram enforces two very different limits: the bio caps at 150 characters, and captions allow up to 2,200 - but only the first line or so shows before the 'more' link. So the real constraint is double: fit the cap, and make the visible opening carry the post.
WordLimit compresses bios and captions to an exact character target while keeping your personality, your keywords, and your call to action. Write the full thought first, then cut it to fit - it beats composing inside a 150-character box.
150 characters is one job: who you are and why to follow. Cut credentials that do not change a visitor's decision.
Only the opening line shows before 'more'. Put the payoff, question, or hook there and let the detail live below the fold.
Hashtags consume caption characters. If you run long, move them to the end and trim the prose first - the tags are not what readers came for.
As of 2026: 150 characters for the bio, 2,200 characters for captions and comments, and 125 characters is the commonly cited visible portion of a caption before truncation.
Paste your draft into WordLimit, set a 150-character target, and it trims to fit while keeping the words that define you. Writing long and cutting precisely beats squeezing from scratch.
Yes. The same character-based reduction fits TikTok captions (2,200 characters), YouTube titles (100), and any other field with a hard cap.
