Sperm whale vs Blue whale
What are they, and what does the difference actually look like?
Two things. One honest scale.
Meet the pair
What these two things are
Blue whale
A blue whale is a baleen whale that feeds by filtering small animals from seawater.
25 mNose-to-tail lengthThe nose-to-tail length of Blue whale is about 1.56 times the length of Sperm whale.

Measurements, assumptions & sources +
Sperm whale
A chosen 16 m, 40 tonne adult male. Length is measured from nose to tail extremity.
Defined examples — our methodology
The marked length is calibrated. Unmeasured illustration details are representative.
Blue whale
A chosen 25 m, 100 tonne adult blue whale (Balaenoptera musculus). Population, sex and age matter: this is a representative comparison specimen, not a record animal.
The marked nose-to-tail length is calibrated. Unmeasured illustration details are representative.

Why these numbers?
The visual compares length with nose-to-tail length. The records below preserve each value’s basis and caveats.

- Comparing
- Length ↔ Nose-to-tail length
- Relative size
- Blue whale is larger on this measurement by a factor of about 1.56. Blue whale's selected measurement is approximately 56.3% greater than Sperm whale's.
How to read the visual
The labelled spans and stored measurements determine the scale; unmeasured illustration details do not.
- Sperm whale is labelled defined specimen; treat the displayed value as a comparison anchor rather than false precision.
- Blue whale is labelled representative; treat the displayed value as a comparison anchor rather than false precision.
