Whale shark is about 1.02× longer by these reference values.
These animals are effectively close in maximum-length terms, so measurement uncertainty can matter more than the apparent difference. Whale shark's weight reference is about 3.5× heavier.

Length bars use upper comparison values and do not show body depth, tail proportion or typical adult size. A long thresher tail, for example, does not equal whale-shark body mass.
THE NUMBERS
Side by side.
WHAT SETS THEM APART
More than a size contest.
Length and weight
Basking shark is represented by reported to 12 m / 40 ft; Whale shark by well documented near 12.2 m / 40 ft. The upper length is exceptional; the mass is a rounded comparison estimate. Exceptional historical lengths exist, but 12.2 m is a conservative comparison value.
Habitat and diet
Basking shark: Temperate coastal and offshore waters; zooplankton. Whale shark: Warm tropical and subtropical seas; plankton and small schooling animals.
Bite evidence
Basking shark: A comparable maximum-bite study is not available for this filter feeder. Whale shark: Whale sharks filter feed; a comparable maximum bite-force study is not available.
Records are not averages
Both species are living, but record-sized individuals are rare. These upper references should not be read as normal adult size.
