Praman married Amphansi Chansue (), née Thangsuphanit (). Amphansi was the eldest child of her family, which ran a business of importing products related to rice mills. She was Praman's childhood friend who lived near his house on
Soi Nom Chit () in Bangkok before World War II broke out. After the war, they accidentally reunited when they found each other living on the same
soi again, that is, Soi Si Nakhon (). The two developed their feelings into love and they were engaged before Praman travelled to the United States for studying at Yale University. Praman and Amphansi married on 3 October 1961. The two had the following three children, respectively: two sons, Ekkathet Chansue () and Ekkaphot Chansue (), and a daughter, Porama Chansue (). ==Honours==
