I'm finally able to properly portray the enormity of a Reaper. The late-21st-century structures in the game are far taller and larger than in our time, so it made the Reapers look smaller than it really are. At 2 kilometers (6,561 ft) long, it's 2.4 times taller than the currently tallest building in the world, Burj Khalifa (829.8 m/2,722 ft), the tower in the center. 

Can you see the 5 bold brown-gold bars at the Burj? From the base, it marks its height from around 50 m, 150 m, 250 m, 400 m, and 500 m respectively, so it's useful for comparison.

Just imagine and compare:

Its front "leg" alone is about 300 m long, nearly as long and probably as big as a Nimitz-class aircraft carrier (333 m/1,092 ft).

  Most incarnation of Godzilla puts him and his enemies at around 50-100 m (164-328 ft). The closest building on the right side of the Burj is around 50 m, and the tallest incarnation of Godzilla at 100 m would stand around the 1st and 2nd bar.

 Gipsy Danger from Pacific Rim is 79 m (260 ft), about the same height as the first setback (a step-looking recession at the building) on the right. Most Kaijus are around 92-96 m, which is slightly more than the 1st setback. The largest Kaiju ever seen, Slattern, estimated to be 181 m tall, would be able to look at the 2nd setback windows on the right.

In front of the Reapers, humans really are just mere protozoa, which is really saying something considering one of those lowlifes is able to screw up their plans and annoy them.
