Who is Finneas O’Connell?
Born July 30, 1997. So Finneas O’Connell’s age in 2026 is 28 years old. Which is crazy when you think about everything he’s accomplished already. 28! Most people are still figuring out their careers at that age, and this guy has already won every major Grammy category.
He’s a Leo, apparently. I don’t know if you care about astrology, but. Creative, confident, natural performer—it kind of fits, actually.
born and raised in Los Angeles. Specifically, Highland Park which used to be this artsy, kinda affordable neighbourhood before everyone discovered it. His childhood home, where they recorded all those early songs, is probably worth like 3 million dollars now knowing LA real estate.
Finneas O’Connell Height
Okay, the Finneas O’Connell height question. He’s about 6 feet tall, give or take. Some sources say 6’0″ others say maybe 6’1″—honestly does it matter that much? That’s around 183 cm if you’re not American. Next to Billie who’s pretty short (5’3″ or so) he definitely looks tall but he’s not like, basketball player height or anything.
Funny thing is. I saw them perform together at a festival once—might’ve been 2023?—and on stage he seemed taller than in photos. Could’ve been the platform shoes everyone wears now. Could’ve been the angle. Who knows.
Finneas O’Connell’s Net Worth: How Rich Is He?

Where does it all come from, though?
**Production fees.** This is huge. After you win Producer of the Year at the Grammys, your rates go up significantly. Like, significantly. He produces for Billie obviously but also Selena Gomez, Demi Lovato, Kid Cudi, bunch of others. Each project pays well.
**Songwriting royalties.** The gift that never stops giving. Every stream of “Bad Guy” or “Everything I Wanted” or “What Was I Made For?”—a little piece goes to Finneas. Those songs have billions of plays combined. The math adds up fast.
