Is Sadie Sink Tall Enough for Jean Grey? How She Compares to the Comics

After weeks of whispers, Sadie Sink finally gave fans one concrete thing to hold onto: she’s in Spider- Man: Brand New Day . That’s it —that’s the list. Marvel and Sony haven’t said who she’s playing or how big the role is, which has turned the internet into a guessing game with one frontrunner towering over the rest: Jean Grey.

Why Jean? Fans are connecting every dot they can find. Sink’s natural red hair lines up with the X‑Men icon’s trademark auburn. They’ve also flagged recent outfits in shades of green and gold—colors long tied to Jean’s Marvel Girl and Phoenix looks—as potential breadcrumbs. And while Tom Holland has publicly waved off the Jean Grey chatter, the theory hasn’t cooled.

The height math

Even height has entered the chat. Comic book bios list Jean at 5'6", and Sink reportedly stands around 5'3". That three-inch gap isn’t exactly a casting dealbreaker in superhero land, but it’s become another datapoint in the fan case file.

Jean Grey is commonly listed at 5'6" in the comics; Sadie Sink is about 5'3".

Here’s how that stacks up against past live-action Jeans:

• Famke Janssen — 6'0"
• Sophie Turner — 5'9"

Both previous versions were taller than the comic-book benchmark. If Sink ends up as Jean, she’d be the shortest live-action take so far—and about as close to the source height as Turner, just on the other side of the ruler.

Why she fits the vibe

Beyond looks, fans see a fit based on résumé. Sink’s Stranger Things run put her through psychic torment, possession, levitation, and world-ending stakes—story beats that rhyme with Jean’s telepathy-heavy, Phoenix-shadowed arc. If Marvel is eyeing a younger Jean, Sink has already logged years of the right kind of genre intensity.

For now, that’s all speculation. Sink’s involvement is official; her character isn’t. Holland has said she’s not Jean Grey, and Marvel hasn’t revealed anything more about who she plays in Spider-Man: Brand New Day.
