She always knew she had a big mouth. Now Guinness says it’s the biggest.

TikTok is full of users with big mouths, but one star on the social media platform just proved hers is quite literally the largest.

Guinness World Records confirmed that Samantha Ramsdell, 31, of Norwalk, Connecticut, is the record holder for the world’s largest mouth gape for a female.

Her “mouth gape” measures 6.56 centimeters, or 2.58 inches. That’s the official vertical measurement between the edges of her teeth when her mouth is open its widest.

Her unstretched measurement across, corner to corner, is 4 inches.

Ramsdell said she has always known she has a big mouth, but it wasn’t until the “children of TikTok” pointed out she may have a record-sized mouth that she was encouraged to go for the record.

Her videos include one of her stuffing three doughnuts in her mouth. She can also fit in a large order of fries.

Ramsdell said she was bullied growing up for her mouth’s size. She didn’t even have anyone with whom to commiserate, as the rest of her family members have conventional-sized mouths.

“It was something that really I was so insecure about, something that I wanted to keep so small,” but it’s now “one of the biggest, best things about me,” she said.

“It’s your superpower. It’s the thing that makes you unique and special,” she said. “Everyone should be celebrating what makes them different.”

The male record is held by Isaac Johnson, a 16-year-old from Minnesota. He first grabbed the Guinness record with a 3.67-inch gap at age 14, was soon dethroned and then, after growing a little, reclaimed it at 4 inches. Ramsdell and Johnson have performed TikTok duets together.
