Blue whale vs City bus Size
Using the game’s measurements, a blue whale has approximately 2.492× the length of a standard city bus.
The bars compare the named dimensions, not area, volume or weight.
The relationship
2.492× the reference size.
The largest blue whales can stretch to roughly two and a half standard city buses.
The whale and bus are both measured end to end. A whale photographed underwater has few familiar objects beside it, so a bus makes a more memorable length anchor.

This game pairs an upper-end 29.9 m blue whale with a representative 12 m city bus. It does not mean every blue whale is this long or every bus uses this model.

Measurement conventions ↗Why photos can fool your sense of scale
Distance from the camera, lens choice and cropping change how large an object appears. Check the named measurement before comparing images. The bars above put both measurements on the same numerical scale, so a longer bar corresponds to the same multiple of the stated dimension.
