A photo has emerged on social media showing Joe and Jill Biden dwarfing Jimmy and Rosalynn Carter.

The picture was first shared by the official Twitter account of The Carter Foundation, a non-profit organization established by Jimmy Carter in the wake of his administration as President of the United States.

Take a look at the photograph right here:

Former POTUS Jimmy Carter, and ex FLOTUS Rosalynn Carter, were visited by the incumbent President Joe Biden and First Lady Jill Biden at their home in Plains, Georgia, on Tuesday, May 4,

A spokesperson for the foundation captioned the image:

"We're pleased to share this wonderful photo from the @POTUS and @FLOTUS visit to see the Carters in Plains, Ga.! Thank you President and Mrs. Biden! [sic]"

But it wasn't long before a number of Twitter users were left bemused by the image, which appeared to show a kneeling Joe and Jill towering over the oddly diminutive-looking Carters.

One social media user wrote: "Dude what is with the size difference between these people what the hell is going on here?"

Another person tweeted: "Not sure who photoshopped this photo but they did a horrible job."

Meanwhile, a third Twitter user asked: "Hello, Carter Center, Why do Flotus and Potus look gigantic next to the Carters, it is a nice photo, but it looks very bizarre, how did that happen?"

A fourth added: "Why do The Carter’s look like miniatures?! They are amazing wonderful people [...] The proportions here are off somehow. Who else agrees?! [sic]"

One Twitter user then tried to use photoshop to enlarge the Carters, to make them match the proportions of the Bidens in the shot. "There. I fixed it," they wrote.

For the record, no, Joe and are not gigantic, and Jimmy and Rosalynn Carter are of average stature. Joe Biden is 6 foot tall, Jill Biden is 5"6, Jimmy Carter is 5"10, while Rosalynn Carter is 5"5.

Since the image became viral online, social media users believe the photographer used a strong flash and a wide-angle lens to capture the group in a tight space; inadvertently creating an optical illusion in the process.
