The rules are optional.

Getting more from these captions

Stay under 150 characters
Instagram allows 150 characters in a bio and every line here fits. Short lines look sharper next to a dark, simple profile photo.
Back the line with proof
A bio about discipline reads better above posts that show it: a training log, a project, a routine. Match the words to what you post.
Do not overdo the slang
One sigma line is a style; three in a row is a costume. Pair it with a plain fact such as your city, your sport or what your page is about.

Questions

What does sigma mean in a bio?

In internet slang, a sigma is a lone-wolf type: independent, quiet and happy to do without a crowd. It is as much a joke as a personality, so a little humour helps.

Can girls use a sigma bio?

Yes. Lines about discipline, calm and walking your own path work for anyone. Swap he or boy for she or girl where needed.

How do I change my bio?

Open your profile, tap Edit profile, paste the line into the Bio box and save. You can change it as often as you like.

Is sigma a real personality type?

No. It is an internet label, not a psychological category. People use it for fun or as a style, so treat a sigma bio as a mood for your profile rather than a claim about who you are.
