Sonic Character Height Chart (Main Series and Sonic Boom version)
So, since there were no official heights for the Boom characters, I decided to see if I could succeed in figuring things out on my own.
Obviously I needed a reference, so this height chart relies on the idea that both Doctor Eggman and his Boom counterpart are the same height, 6′ 1″ (185 cm). After that, I took screenshots from the show and tried to estimate heights based on them.
The weird thing is that heights seem to fluctuate in the show. I had two different heights of Eggman and Amy standing right next to each other, but Amy’s height wasn’t consistent. I dunno if there was some weird perspective going on or not, but I still did my best.
Now, for this chart, I tried to take into account how characters are leaning or bending, hence why main!Eggman doesn’t line up perfectly on the height chart, but is still the same height as his counterpart. The soles of their shoes also don’t count obviously and I measure heights based on the spot between their ears (so since Sonic’s quills go up the further back they go, I don’t count it; in my experience, it helps make heights look more correct. If I do it this way and Amy and Sonic were the same height, they’d look it because their eyebrows/eyelashes match up)
Again, this is all estimation, so don’t ask why the Boom characters are so much taller than the main series characters. There weren’t a ton of shots with the characters standing close enough to each other to where I could get a good enough comparison, but hopefully my effort isn’t in vain either.
