This and its sister species are the largest members of the Procellariidae. The southern giant petrel measures with a wingspan of . Both this and the northern giant petrel vary considerably in size, with southern colonies averaging larger than northern colonies, in line with Bergmann's rule
Bergmann's rule is an ecogeographical rule that states that within a broadly distributed taxonomic clade, populations and species of larger size are found in colder environments, while populations and species of smaller size are found in warmer ...
. Due to the large amount of size variability, it is difficult to determine which is the larger species, but the largest-bodied colonies of the southern species are slightly larger on average, in both mass and linear dimensions, than the largest in the northern giant petrel. Body mass can vary widely, from , with males averaging larger than females. The largest average weights come from Macquarie Island
