Optimus Prime vs Gorilla: the size gap, measured
Optimus Prime measures 8.5 m (27.9 ft) from the ground up, and a gorilla measures 1.3 m (4.27 ft) from the ground up. Optimus Prime comes to 6.54 times the height of a gorilla, a difference of 7.2 m (23.6 ft). Take 6 gorillas stacked up and you reach 7.8 m (25.6 ft), still 70 cm (27.6 in) short of Optimus Prime; one more would overshoot by 60 cm (23.6 in). Optimus Prime and a gorilla are both written in single metres, so the 6.54-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, Optimus Prime and Gorilla, 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
Optimus Prime has never been measured, only stated: the figure comes from its source and moves when the source is redrawn, while a gorilla can be checked with a tape, so this pair sets a decision against a measurement. Optimus Prime is drawn about 3.36 times as wide as a gorilla as well as 6.54 times its height, so the area it takes in the frame grows faster than the figure anyone quotes. Optimus Prime sits in the range with no handy yardstick: too big to hold against anything you have carried, too small to need a horizon, so it and a gorilla end up filed under the same vague heading of very large.
What each figure covers
Optimus Prime. The height is the live-action film design. The animated original was quoted far smaller, and the two have almost nothing in common at scale.
Gorilla. Gorillas are quoted standing height at the shoulder rather than upright on two legs. They move on their knuckles, so the standing figure is the one that matches how you ever see them.
Optimus Prime and a gorilla 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, Optimus Prime at 8.5 m sits within a tenth of AT-ST Walker at 8.6 m and TIE Fighter at 8.8 m. Gorilla at 1.3 m has Gimli at 1.37 m, Lord Farquaad at 1.37 m and A0 Paper at 1.19 m for company, within a tenth. Swapping any of those in for Optimus Prime would move its ratio to a gorilla by less than 10%.
