Mega Steelix Size Comparison: BETA
Mega Steelix is listed at 34' 5" (10.5 m) and shown in an in-chart visual comparison.
How is visual size determined?
Pokédex height is treated as the official listed measurement, but the chart uses pose-aware visual scaling so each sprite looks reasonable in a direct comparison.
For long or coiled Pokémon, the listed height may represent total body length rather than upright height. For Pokémon with floppy ears, leaves, feathers, antennae, wings, or other flexible features, the chart usually measures to the top of the solid, substantial part of the head or body instead of the tallest decorative feature.
The goal is not to replace the official height, but to make the artwork compare naturally at the size it appears to occupy.
