Sand tiger shark is about 1.04× longer by these reference values.
These animals are effectively close in maximum-length terms, so measurement uncertainty can matter more than the apparent difference. Sand tiger shark's weight reference is about 1.45× 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 THE DATA CAN SAY
Size is not the whole animal.
Length and weight
Nurse shark is represented by recorded to 3.08 m / 10.1 ft; Sand tiger shark by reported to about 3.2 m / 10.5 ft. Length is a recorded maximum; mass is a rounded adult reference. Upper records vary by region and source.
Bite evidence
Nurse shark: Suction performance is central to feeding and is not captured by bite-force rankings. Sand tiger shark: A reliable comparable maximum was not found.
Living versus extinct
Both species are living, but record-sized individuals are rare. These upper references should not be read as normal adult size.
Ecology changes the matchup
A small mouth and powerful suction suit its bottom-feeding life. Its protruding teeth look dramatic, but appearance alone does not reveal bite force.
