Brother bio for Instagram: lines for a big brother

For the one who walked ahead and still waits at the corner.

Big brother, first protector.
He fixed my bike, my phone and my confidence.
Older by years, wiser by a mile.
Big brother energy: calm in every storm.
The first friend I ever had was him.
He teased me, then he taught me.
My elder brother, my ready backup.
Taller than me, braver than me, there for me.
Bhaiya mode: always on.
The one who says, I will handle it.

For a little brother

Annoying, adored and the reason the house is loud.

Little brother, big trouble.
Born to borrow my chargers.
Small in size, huge in drama.
The baby of the family and boss of the remote.
Tiny tornado with my last name.
Cutest brat I know.
Little brother, full-time chaos.
I am the reason my brother learned patience.
Younger, louder and somehow always forgiven.

Getting more from these captions

Keep it under 150 characters
Instagram allows 150 characters in a bio, and every line here fits. Short lines leave space for a link or a tag.
Ask before you tag him
For an Instagram bio, brother lines work best when he would be glad to see them on your profile, so check with him before you tag his account or post his photo.
Match the joke to the sibling
A teasing line works when both of you laugh at it. If you are unsure, choose from the love set and save the roast for a private chat.

Questions

Can you suggest a good bio for my brother?

Say one true thing about him in a line: what he does for you, what he is like on a bad day, or a joke only the two of you get. Short and specific beats long and general.

Can I use a brother bio on my own profile?

Yes. A line like “Brother by birth, friend by choice.” works on a personal profile and tells people who matters to you.

What if I want captions, not a bio?

Open the brother captions page for photo lines, or the brother birthday page for his big day.

Should I mention my brother by name in the bio?

Only if he is comfortable with it. A line such as “Proud sibling of the loudest brother.” says the same thing without exposing his name or his account.
