How big is Blue whale?
For this comparison, Blue whale measures 33.5 m in length (110 ft). Up to 110 feet for Antarctic blue whales; an upper size, not a typical adult.
Body length runs from the front of the head to the tail. The silhouette measures that full length.
Put the measurement in perspective
The recorded length is 19.722 times the height of A 1.70 m person (1.7 m). This is a ratio of the labelled linear dimensions. It does not describe weight, area or volume.
Use the interactive comparison to see both drawings on one shared scale. You can choose another reference or enter your own height. If the sizes are very far apart, the smaller object may be almost invisible; an intermediate reference makes the progression easier to inspect.

Check the convention
An animal’s size can vary with sex, age, population and individual. A selected upper limit or illustrated adult value is not a species-wide average.
Read our methodology for the selection and scoring rules. Practise these dimensions in the animals size guessing game.
