These are subjective things, sure. My personal feeling upon seeing the shuttle was that it was not that big, because I've seen big airliners all my life. I was expecting the shuttle to be bigger. So when I looked at the parent's infographic and saw a 737 and the Statue of Liberty there, they didn't seem right (I've also seen the SoL in-person). So the size comparisons I think are quite misleading in that graphic, and yeah, I was surprised how much smaller the shuttle is than what I expected.
