The boilerplate listings say 5.5 inches, which has got a few people worked up, but the Hasbro staff have said that they are taller (they proclaimed them voyagers, as if that helps with the height these days). And if you look at the size of the (non-partsforming) limbs and compare them to the Aerialbots (which we know are average-height deluxes that come apart in the middle to fit on the Superion frame), you can work out that they are indeed larger. So I would hazard a guess of average, perhaps even slightly above-average, height for a 2025 voyager-price-point toy.
