It could hardly be called a face-to-face encounter, and conversation must have been a little difficult.
But as they met for the first time, Sultan Kosen, the world's tallest man at 8ft 1in, and He PingPing, the world's smallest at 2ft 5.4in, clearly had a mutual respect.
The Turkish farm labourer and the pint-sized man from China were happy to pose at an event in Istanbul to mark the opening of the new Guinness World Records Live! Roadshow.
Kosen said: 'I've wanted to meet Pingping ever since I was awarded the title "tallest man" and I'm really happy that he was willing to travel to Turkey so we could both take part in the launch celebration of Guinness World Records Live! at Forum Istanbul - I can't wait to show him around our beautiful city.'
Also the world record holder for the largest hands and feet, Kosen, 27, seized the title of world's tallest man from China's Bao Xishun last September, beating his rival by 10cm.

Last year, He PingPing met Svetlana Pankratova, the woman with the world's longest legs - measuring 51.96in long
At the opposite end, He PingPing, 21, suffers from a condition known as Primordial Dwarfism.
He lives with his family in Inner Mongolia, China and has travelled the world since being recognised by Guinness World Records.
Last year, He PingPing met Svetlana Pankratova, the woman with the world's longest legs - measuring 51.96in long.
