How big is Pikachu compared to Patrick Star?
Pikachu measures 40 cm (15.7 in) from the ground up, and Patrick Star measures 15.2 cm (6 in) from the ground up. Patrick Star would have to grow by 162% to match Pikachu, which is 2.62 times its height. Take 2 Patrick Stars stacked up and you reach 30.5 cm (12 in), still 9.52 cm (3.75 in) short of Pikachu; one more would overshoot by 5.72 cm (2.25 in). Pikachu and Patrick Star are both written in tens of centimetres, so the 2.62-to-one gap has to be read off the digits rather than off the unit.
| Object | Real size | Axis measured | What the figure covers |

Both figures, Pikachu and Patrick Star, 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
Pikachu is drawn about 3.45 times as wide as Patrick Star as well as 2.62 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 2.62 to one obvious between Pikachu and Patrick Star, and it is not: at this size the eye compares whole outlines while the figures above compare one axis.
What each figure covers
Pikachu. Pikachu is quoted at its official entry height, unchanged since 1996. Forty centimetres is smaller than almost every drawing of it suggests.
Patrick Star. The height is the studio figure for the character. Sea stars in reality are measured across the arms rather than vertically, so the standing pose is a cartoon convention.
Pikachu and Patrick Star 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, Pikachu at 40 cm sits within a tenth of Woody at 40 cm, A3 Paper at 42 cm and Emperor Zurg at 38 cm. Patrick Star at 15.2 cm has Ostrich Egg at 15.6 cm, iPhone 16 at 14.8 cm and Mr Potato Head at 14 cm for company, within a tenth. Swapping any of those in for Pikachu would move its ratio to Patrick Star by less than 10%.
