Marie Pearl Zelmer Robinson from the US set a Guinness World Record for the largest mouth gape at 7.62 cm, surpassing the previous record of 2.56 inches.
Marie Pearl Zelmer Robinson’s mouth measures an astounding 7.62 centimetres (3 inches).
In a revelation that’s as startling as it is fascinating, a woman from the United States – Marie Pearl Zelmer Robinson – has officially secured her place in the Guinness World Records as the woman with the largest mouth gape in the world, a distinction she claims was hiding in plain sight for years.
Measuring an astounding 7.62 centimetres (3 inches) when fully agape, Marie’s mouth easily eclipses the previous record of 2.56 inches held by Samantha Ramsdell. She can effortlessly fit a towering burger stacked with ten patties between her jaws – a feat that defies belief until witnessed in person.
But Robinson’s record-setting moment could have come much sooner – if not for an unfortunate scheduling conflict. Back in 2021, she had a chance to claim the title when her hometown hosted an event associated with Guinness World Records. Ironically, the occasion had nothing to do with mouths but with wellies: nearly 2,000 people gathered to break the record for the world’s largest Wellington boot race. Marie, however, had to miss the event – duty called at the courier business she runs with her husband.
It wasn’t until she stumbled across online videos showcasing the reigning male and female record-holders for the largest mouth gape that Marie realised she might have them beat – quite literally by a wide margin. “I was watching the videos and I thought, ‘Wait a second, there’s a record for that? And people are measuring it?'” she recalled with a laugh. “I grabbed a ruler, looked in the mirror, and thought – I can totally do that,” she said.

Marie’s unique ability to stretch her mouth isn’t just about muscle flexibility or freak genetics. In fact, the phenomenon has a physiological twist. She describes her jaw as being positioned unusually high – so much so that she can feel it extend into her ear canal, something she says is extremely rare.
“Most people, when they open their mouth wide, their jaw presses against tendons and muscles. But mine doesn’t – it just keeps going,” she explained. “It’s not something you’d notice unless you’re really paying attention to where your bones are. I always felt something different, but I never imagined it would be a world record,” she added.
And it’s not just burgers that showcase her talent. Marie boasts that she can comfortably fit three and a half Jenga blocks in her mouth – though she admits her penchant for talking probably trained those muscles well over the years.
