Okay, let’s settle the biggest mystery since who ate the last slice of pizza: how old is Steven in The Summer I Turned Pretty? You might think you know, but the math is more tangled than a pool floatie in a hurricane. Grab your metaphorical lemonade; we’re diving into the age drama.

The Not-So-Secret Canon Age

According to the books by Jenny Han, Steven Conklin is born in 1988, making him three years older than Belly. In season one of the show, Belly is turning 16, which puts Steven at a solid 19 years old. Wait—19? That’s old enough to buy scratch-off tickets but still young enough to cry over a breakup. It’s the awkward twilight zone of legal adulthood.

But here’s where it gets silly: the actor who plays Steven, Sean Kaufman, was actually 27 when filming started. That’s right—he was closer to 30 than to 19. So canonically, Steven is a teenager, but in reality, he could mentor the teenagers and collect a 401(k). It’s Hollywood magic, folks.

Why Does It Even Matter?

Because Steven’s age is the secret sauce to his entire personality. He’s supposed to be the responsible older brother, but at 19, he’s still a baby. He whines about his girlfriend, gets jealous of Jeremiah, and acts like a total goofball. If he were 27, he’d be a full-grown man with a mortgage and a midlife crisis.

Instead, he’s trapped in that “college sophomore” phase where you think you’re mature but still eat cereal for dinner. It’s perfectly awkward, and that’s why we love him. He’s old enough to drive Belly to school but young enough to steal her fries.

A Shocking Timeline Twist

Here’s a fact that will blow your mind: in the books, Steven graduates high school a year early. That means he’s actually 18 when the story starts, not 19. The show changed it to 19 for drama—because nothing says “summer romance” like a slightly older dude brooding on a beach. It’s a blatant age hack to make him seem more worldly.

And get this: Belly is 13 in the flashbacks, which makes Steven only 16. So their sibling dynamic is extra weird—he’s basically a toddler in guy years. No wonder he can’t handle his emotions.

The Verdict: He’s an Eternal Teen

Ultimately, Steven’s age is a beautiful, confusing blur. In your heart, he’s 19—a big kid with a driver’s license and zero life experience. But in the Hollywood math, he’s whatever age makes the plot work. Don’t overthink it; just enjoy his dramatic fits.

So next time you watch, remember: Steven is old enough to vote, but young enough to still live in his parents’ beach house. He’s the eternal teenager, and that’s the only answer that matters. Now pass the sunscreen—I’m sweating from all this math.
