How big is an iPhone 16 next to an Irukandji jellyfish?
An iPhone 16 measures 14.8 cm (5.81 in) from the ground up, and an Irukandji jellyfish measures 3.2 cm (1.26 in) from the ground up. An iPhone 16 comes to 4.61 times the height of an Irukandji jellyfish, a difference of 11.6 cm (4.55 in). Take 4 Irukandji jellyfish stacked up and you reach 12.8 cm (5.04 in), still 1.96 cm (0.8 in) short of an iPhone 16; one more would overshoot by 1.24 cm (0.5 in). An iPhone 16 is written in tens of centimetres and an Irukandji jellyfish in single centimetres, a whole band of scale apart.
| Object | Real size | Axis measured | What the figure covers |

Height | Ground to highest point |
| Irukandji Jellyfish | 3.2 cm 1.26 in |
Height | Average Adult |
Both figures, iPhone 16 and Irukandji Jellyfish, come from the Size It Up measurement set, one real-world size and one measured axis per object, last checked in September 2026; outline provenance is listed on the sources page.
Why this one is hard to judge by eye
An iPhone 16 is drawn about 3.70 times as wide as an Irukandji jellyfish as well as 4.61 times its height, so the area it takes in the frame grows faster than the figure anyone quotes. Both shapes fit in a single glance here, which ought to make 4.61 to one obvious between an iPhone 16 and an Irukandji jellyfish, and it is not: at this size the eye compares whole outlines while the figures above compare one axis.
What each figure covers
iPhone 16. Phone heights are fixed to a tenth of a millimetre because cases are made to them. It is the most precisely specified object in this set and the one that dates fastest.
Irukandji Jellyfish. The figure covers the contracted animal, bell and tentacles together. Extended, the tentacles reach far beyond it, and the bell alone is barely a centimetre.
An iPhone 16 and an Irukandji jellyfish are both quoted as a height, which is what makes the ratio above a like-for-like figure.
What else is about that size?
Measured the same way, iPhone 16 at 14.8 cm sits within a tenth of Patrick Star at 15.2 cm, Mr Potato Head at 14 cm and Ostrich Egg at 15.6 cm. Irukandji Jellyfish at 3.2 cm has UK 50p Coin at 2.73 cm for company, within two fifths. Swapping any of those in for an iPhone 16 would move its ratio to an Irukandji jellyfish by less than 10%.
