POKHARA, Nepal – Khagendra Thapa Magar is a little man facing a big day.

Today — his 18th birthday — he will officially be named the world’s shortest man, assuming his measurements read the expected 25.8 inches.

His family has been campaigning for years to get Thapa the crown, but earlier requests to Guinness World Records were rejected because of the possibility he might grow.

Once his measurements are taken three times in the span of 10 hours, he is expected to overtake Edward Nino Hernandez of Colombia, who measures 27 inches.

His father says he has no explanation for why Thapa never grew — his younger brother is a normal height for a boy of 13.

Thapa behaves like a young child and attends kindergarten.

While his father was excited for Thapa to finally enter the record books, the young man was more focused on his birthday festivities.

“I want a big chocolate cake with red decorations,” he said.
