Kosen was set to marry Merve Dibo -- who's about two-and-a-half feet shorter than he -- Sunday in the Turkish city of Mardin, the Anadolu Agency reported.
While preparing for his wedding, the Guinness Book of World Records-certified tallest man in the world told Anadolu Agency he had given up hope that he'd meet a life partner when an acquaintance introduced him to Dibo.
"Now I will have my own family and private life," Kosen said.
While saying it was "unfortunate I could not find a suitable girl of my own size," Kosen said, "but I believe I've found the person for me."
Kosen said all he really wanted now was a vehicle that can accommodate his frame so he can travel comfortably with Dibo, the news agency said.
Besides his record height, Kosen also is in the Guinness records because of his nearly 9-inch-wide hands and 14-plus-inch-long feet.
