How Old Are The Summer I Turned Pretty Characters

Ever found yourself completely hooked on The Summer I Turned Pretty and wondered exactly how old the characters are? You’re not alone. The ages are a huge part of why the show feels so messy, real, and totally addictive.

The Core Trio: Belly, Conrad, and Jeremiah

Our main character, Isabel “Belly” Conklin, is sixteen in the first season. She’s right in that awkward, magical space between being a kid and becoming a young woman. That age explains why she’s so dreamy and also why she makes some truly questionable decisions.

Then there are the Fisher brothers. Conrad Fisher is seventeen, just one year older than Belly. He’s a senior in high school, which gives him that brooding, “I know everything” energy that drives Belly crazy. Jeremiah Fisher is sixteen, the same age as Belly, which makes their friendship feel more equal and playful.

This tiny age gap—just one year between Belly and Conrad—is the engine of the whole love triangle. It creates that perfect tension of almost-but-not-quite.

The Adults and Timeline Shifts

The parents aren’t just background noise. Susannah Fisher and Laurel Conklin are in their late forties, and their friendship is the emotional backbone of the story. Their ages give them a wisdom (and a few health scares) that makes the teen drama feel grounded.

In the second season, the story jumps back to when Belly was fifteen. That’s a big deal because at fifteen, everything feels like life or death. Plus, you see the brothers at sixteen and seventeen, which helps explain why they act so differently in the present.

This time jump isn’t confusing—it’s genius. It lets you watch them grow up in front of your eyes, which is exactly what makes the show so binge-worthy.

Why Ages Matter So Much

Honestly, the show knows that being sixteen or seventeen is a special kind of terrible and wonderful. At that age, every text message feels monumental, and every summer kiss could change your whole life. Belly isn’t a mature adult making rational choices—she’s a teenager, and that’s why you root for her even when she’s a mess.

Conrad at seventeen is dealing with adult-sized heartbreak while still being a kid. Jeremiah at sixteen is trying to be the fun, carefree one while hiding his own pain. These ages make their flaws feel real, not annoying.

“It’s like the show bottled that feeling of being young enough to dream but old enough to get your heart broken.”

Even the adults feel age-appropriate. Laurel is a writer in her prime, Susannah is a mother facing serious challenges. Their ages add weight to the lighter poolside drama.

Quick Age Reference Table

Here’s the cheat sheet: Belly is 15-16, Conrad is 16-17, Jeremiah is 15-16, Steven (Belly’s brother) is 17-18, Laurel is late 40s, Susannah is early 50s. The ages shift slightly between seasons, but the core dynamic stays the same.

You’ll notice that Taylor, Belly’s best friend, is also sixteen. That’s why her drama with Steven feels so high school—because it is. Every character’s age fits their role like a glove.

The Magic of Being That Old

What makes The Summer I Turned Pretty so special is that it doesn’t try to make teens act like tiny adults. Belly gets jealous, makes mistakes, and says stupid things—because she’s sixteen. Conrad shuts down and acts moody—because he’s seventeen.

So if you’ve ever wondered why you can’t stop watching, it’s because the ages are perfectly picked. You get the thrill of first love, the mess of growing up, and the comfort of knowing that even at sixteen or seventeen, everything will eventually turn out okay.
