Instagram Bio
120+ original instagram bio you can copy in a single tap. Every line is written in-house for Saylines — nothing here is scraped or reposted — and every card is free to download and share.
An Instagram bio has a hard 150-character limit, which is the single constraint that shapes everything about writing one. A line that would work fine as a caption often has to be cut in half before it fits, and the cut usually improves it.
Bios that mention a specific person — a best friend, a sibling, a child — work differently from generic ones. They date the profile to a relationship, which is the point: the bio is telling visitors who matters, not describing a personality in adjectives.
The collections below are grouped by who the bio is about, with short lines, warmer lines, and a few with some humour. Everything is written in-house and free to use.

30+ Instagram Bio Ideas About Your Cousin
Cousins occupy an odd space: family by default, friends by choice, and usually the people who have known you longest outside your own house. These bio lines lean into that rather than treating a cousin as a generic relative.

Frequently asked questions
How many characters can an Instagram bio be?
Instagram allows 150 characters, including spaces and line breaks. Most bios that read well use far fewer than that.
Should a bio mention a specific person?
It works when that relationship is genuinely central to the account. A bio naming a best friend or a child reads as sincere; a bio naming whoever is current tends to age badly.
Can I add line breaks to an Instagram bio?
Yes, though the app sometimes strips them when typed directly. Writing the bio in a notes app and pasting it in usually preserves the breaks.
Are these Instagram bio lines free to use?
Yes. Every line here is original to Saylines and free to use without credit.
