The largest iceberg on Earth in 2019 was A68A, which calved from the Larsen C Ice Shelf in the Antarctic Peninsula in July 2017. When it was born (and christened A68), the iceberg measured some 6,000 square kilometres (2,317 square miles). A68A is the largest remnant and currently around 152 kilometres (94 miles; 82 nautical miles) long and 48 kilometres (30 miles; 26 natutical miles) wide, according to NOAA's National Ice Center as of 29 November 2019. It's estimated to be around 200 metres (660 feet) thick. It is currently being carried northwards, where it will soon enter the South Atlantic’s "Iceberg Alley".

A much smaller chunk, which detached from A68 soon after the berg was born, is known as A68B and is over 100 kilometres (60 miles) to the north of A68A.

The largest iceberg that was produced in 2019 was D28, which calved from the Amery Ice Shelf in East Antarctica. This tabular iceberg covers 1,636 km² (632 sq mi) in area and is thought to be over 200 m (660 ft) thick.

For comparison, the largest confirmed iceberg (as measured by satellites) was B15, which calved from Antarctica's Ross Ice Shelf in March 2000 and had an initial surface area of around 11,000 km² (4,250 sq mi).
