Snakes are measured in length: the orange bar is their true length, next to the man. The photos (coiled) aren’t to scale.
Dogs: shoulder height of males, the tallest in the FCI breed standard. Cat: average measured height (no source gives a maximum). The others: maximum adult length (or shell, or leg span). Photos are scaled by eye on the measured point: the real size is the number. Photo authors and licenses: in “Sources and method”.
Always ask your vet: this site helps you understand, it doesn’t replace a checkup.
