Kenyon Lee, 18, has become a TikTok sensation in recent weeks for guessing people's heights based on just photos and math. Lee has 2.5 million followers and as many as 20,000 requests a day from people who want him to guess their height.

It started when he spotted a TikTok user issuing a challenge to guess their height. Lee figured it would make for interesting content if he could solve that problem, and — like a good math student — show his work.

By the evening after he posted a response, his video had one million views.

"I experimented with some other content, but every time I did a 'guess my height' video it just kept going up and up to the point where I did one video that got 17 million [views] in two or three days, and I was like, OK, I need to just adopt this as kind of my thing," Lee told As It Happens guest host Helen Mann.

His method involves a combination of detective work (by looking at their posted photos) and then calculations based on the established ratios of the human body.

"What I typically do is I try and find somebody's wingspan, which follows closely a one-to-one ratio with someone's height. And so typically I just find posts next to where people have, like, random objects in their pictures, and I use that to find their wingspans," Lee said.

Lee can't make money from his videos on TikTok, so he’s started a YouTube channel to see if he can build a presence on a platform where he can potentially earn some cash to help fund his education.

And for now, he's simply having fun with this project.

"Other people just see this as just, like, you know, really crazy, like I'm just some big celebrity," he said. "But, I don't know, it's like a hobby to me."
