The name Tiengemeten refers to an ancient area measurement; one gemet is comparable with one acre so the name means ten-acre island. Ten gemets would be about 100 by 400 metres (330 by 1,310 feet), while the island is actually about 7 km (4 mi) long and 2 km (1 mi) across at its widest.

The statistical area "Tiengemeten" had a population of around 10 until 2007.^[1] On 10 May 2007, the island was officially allowed to revert to its natural state after its inhabitants were relocated.^[2]

The Rien Poortvliet museum is located on the island.
