A little perspective
Tyrannosaurus rex vs Badminton court: length comparison
The length of a badminton court is about 1.12 times the adult length of Tyrannosaurus rex.
Tyrannosaurus rex was a large, meat-eating dinosaur from the late Cretaceous period, recognised for its massive skull and powerful jaws.
A badminton court is the marked rectangular playing surface used for games of badminton.
Both rulers start at the same zero and share one linear scale. Artwork keeps its original proportions. Horizontal rulers compare the selected spans; vertical brackets also identify height on the artwork.

Why this measurement?
Why we use 12 m
We compare the adult length of Tyrannosaurus rex. This is a representative comparison value; individual specimens or conditions can vary. The recorded range is 11 m to 13 m.
A representative large adult Tyrannosaurus rex at 12 m and 8 tonnes. Fossil reconstruction and mass models vary; these are rounded comparison values.
