What measurements does this comparison use?
The reference values used here are 12.3 m for Tyrannosaurus rex (Length, estimate from fossils) and 4.9 m for Mid-size sedan (Length). The table links to background sources; natural objects and manufactured variants can differ from these reference values.
How should I read the drawing?
Tyrannosaurus rex spans about 2.5× as much as Mid-size sedan across the longest side of each drawing. This is a linear scale comparison, not a comparison of mass or volume. For maps, the table reports area; doubling a map’s width and height multiplies its area by four.
