Scale Or Perspective?

it is sometimes so difficult to relate the size of objects,

most New Yorkers know how big Central Park is, but a super tanker as sea has no comparison to judge it's size, enter college student Kevin Wisbeth, creator of the Youtube series “A Quick Perspective,” puts size in layman’s terms for those who might not be able to conceptualise the world’s largest oil tanker into New York’s Central Park, to give the tanker some idea of scale, if the Seawise Giant (1,504 ft), the largest oil tanker ever produced, was placed into the main lake in New York City’s Central Park, it would only have 350 feet of extra room in the front and back of the tanker,

 if the Titanic (882 ft) was placed on the deck of the U.S.S. Ronald Reagan, the ship would have 210 feet of deck room left,

 the M-1 Rocket motor was designed back in the 1950s for the NASA space program and would have been the biggest motor ever built had it been constructed, it’s designed diameter was 14 feet, or wide enough to fully cover a Smart Car with 2 feet to spare on either side,

but for me this is the scary one, I have always known that prehistoric bugs were larger than average day bugs due to the higher oxygen levels, the Pulmonoscorpius kirktonensis was a species of scorpion that grew to 24 inches long, or the size of a normal house cat, I would not like to meet one of those on a dark night, well any night for that matter!
