How Old Is Jeremiah From The Summer I Turned Pretty

Okay, let’s talk about Jeremiah Fisher. You know, the golden-haired, fun-loving brother from The Summer I Turned Pretty. If you’ve been binging the show or flipping through the books, you’ve probably paused to wonder: how old is this guy, anyway?

Let’s break it down without making it feel like homework. In the books by Jenny Han, Jeremiah is 16 years old in the first summer. That makes him just a year younger than his brooding brother, Conrad, who is 17 at the start. Wait—does that make sense with the show?

The Show vs. The Books: A Tiny Age Gap

Here’s where it gets a little loose. In the TV series, Jeremiah is played by Gavin Casalegno, who was actually 22 when filming started. But the character is meant to be younger—around 15 or 16 in Season 1. Why the difference? Well, TV casting is a vibe, not a science lesson.

So if you’re asking for canon answers, stick with the books. Jeremiah Fisher is a sophomore in high school during the first summer. He’s that sweet spot of being old enough to drive his mom’s car but young enough to still be a little reckless.

Why Does His Age Even Matter?

Honestly, it’s not just about numbers—it’s about the vibe. Being 16 means you’re in that weird zone between childhood and, like, real heartbreak. Jeremiah is fun, easygoing, and always cracking jokes. But his age also explains why he’s so fiercely protective of Belly and his brother.

How old The Summer I Turned Pretty are compared to characters?

How Old Do You Feel Watching Him?

Here’s a fun curveball: if you’re watching the show as an adult, Jeremiah might feel older than 16. That’s because actor Gavin brings this mature, steady energy to the role. He’s like a golden retriever who secretly knows how to change a tire—you know?
