Boaz stood on the left and Jachin ("founding", Tiberian Hebrew יָכִין Yāḵîn) stood on the right. The pillars had a size nearly six feet (1.8 metres) thick and twenty-seven feet (8.2 metres) tall. The eight-foot (2.4 metres) high brass chapiters or capitals on top of the columns bore decorations of brass lilies.
The original measurement as taken from the Bible was in cubits, which records that the pillars eighteen cubits high and twelve cubits around, and hollow, four fingers thick. (Jeremiah 52:21–22). Nets of checkerwork covered the bowl of each chapiter, decorated with rows of two hundred pomegranates, wreathed with seven chains for each chapiter, and topped with lilies (1 Kings 7:13–22, 41–42).
The Romanesque Church of Santa Maria Maggiore at Tuscania has a recessed entrance flanked by a pair of free-standing stone columns intended to evoke Boaz and Jachin.

Some variants of the Tarot card The High Priestess depict Boaz and Jachin. The card appears in the deck of a traveling Mexican showman in Cormac McCarthy's novel, Blood Meridian: "The woman sat like that blind interlocutrix between Boaz and Jachin inscribed upon the one card in the juggler's deck that they would not see come to light, true pillars and true card, false prophetess for all."
