He’s fictional. Everyone knows that. Doesn’t matter, because Jeremiah Fisher from The Summer I Turned Pretty still gets talked about like a real ex someone’s still not over. Played by Gavin Casalegno, all golden retriever charm, and yes, the guy Belly almost married before the finale pulled the rug out.
- Jeremiah Fisher is played by Gavin Casalegno, born 2 September 1999 in Dallas.
- Casalegno is 26 right now, turning 27 this September.
- He’s around 6 feet tall. No studio has ever put an exact number on it.
- Belly ends up with Conrad, not him.
- The show writes him as bisexual. The books didn’t.
- A movie’s been filming since April 2026, though nobody’s confirmed a release date yet.
How Old Is Jeremiah Fisher, Really?
Here’s the thing about Jeremiah’s age – the show just never says it. So fans do the obvious thing and dig up Gavin Casalegno’s actual birthday instead. He was born on 2 September 1999, which makes him 26 in 2026. And yeah, that means he spent years playing a character who’s supposed to be a teenager while being closer to 25. Classic teen drama move really. Nobody wants a 16-year-old actor doing 12-hour set days, so you cast someone a decade older and hope the lighting does its job.

How Tall Is Jeremiah Fisher? Here’s What We Actually Know
Nobody’s officially confirmed it, but most sources put Gavin Casalegno at around 6 feet. Makes sense too – he towers over Belly in nearly every beach scene, and that’s not just clever camera angles.
Jeremiah Fisher’s Real Name Isn’t What You’d Think
Here’s a fun one – Jeremiah isn’t even his real name – he’s fictional. The actual person is Gavin Perry Casalegno, a Texas kid who started modelling before he could probably read, then spent years doing bits and pieces nobody really remembers, a small part in Noah, young Damon in The Vampire Diaries. Then 2021 rolls around, he books Jeremiah, and that’s genuinely the moment everything shifted. Before that, he was just “that kid from Noah, maybe.” After, he’s got fans dissecting his every Instagram post.
Wait, Is Jeremiah Fisher Gay?
No, he’s bisexual, and that’s not an accident. In Jenny Han’s original 2009 book, Jeremiah’s only ever into girls. The show changed that on purpose. Han’s talked about writing him as sexually fluid early on, someone still working things out. Later seasons make it clearer, with Jeremiah mentioning past flings with guys and girls both. Hans said the heart of the character never changed – it’s just a different, more modern take on him.
