Man with largest thumb in the world reveals daily struggles of trying to use cellphone

A Massachusetts man with one of the world’s largest thumbs has shown off how he uses everyday items like his phone.

Jacob Pina, 25, has gone viral for his five-inch thumb, which has helped him launch a successful YouTube channel and gain millions of online followers.

But while it has given him internet fame, it has made daily tasks a bit harder, including texting and using his cellphone.

At about five inches fully stretched, his right thumb is just slightly shorter than the six-inch iPhone 16.

He demonstrated this in a recent TikTok video, where he stretched out his thumb to scroll through social media on his phone.

The clip, which has hundreds of thousands of views, left viewers shocked and confused, with many questioning if it was edited or if the extreme stretch is painful.

One commented: “This makes me physically uncomfortable.”

One said: “Is it some sort of condition that causes this or is it edited?”

Another commented: “You don’t understand how confused i am.”

“Bro this is a sword,” one viewer said.

He also shared a video comparing his thumb to a normal thumb, with his looking to be three times longer.

Around one in 10 Americans have highly flexible or stretchy joints, also known as hypermobile joints – but doctors have no explanation for Mr Pina’s case.

Though hypermobility has been linked to genetic disorders, he said he doesn’t have any underlying health issues to explain his thumb.
