It's about one-and-one-fifth times as tall as The Great Pyramid of Giza.
In other words, the height of The Great Pyramid of Giza is 0.83 times 520.97 feet.(a.k.a. Pyramid of Khufu, a.k.a. Pyramid of Cheops) (Cairo, Egypt) (estimated original height)
The Great Pyramid of Giza has an estimated original height (without loss due to erosion) of 430 feet. The Pyramid was the tallest structure in the world for almost 4,000 years — from its construction ca. 2551 BCE until it was overtaken by the Lincoln Cathedral in Lincoln, England, built in the year 1300.
It's about seven-tenths as tall as The Golden Gate Bridge.
In other words, the height of The Golden Gate Bridge is 1.43 times 520.97 feet.(San Francisco, California and Marin County, California) (height above water)
The height of each tower of Golden Gate Bridge is 745 feet above the surface of the San Francisco Bay. One of the key designers of the bridge, Charles Ellis, had no engineering degree when he began working on the project, but would later go on to write what became a standard textbook on structural engineering, and would ultimately be forced to complete his calculations on the bridge by working without pay for five months.
It's about one-and-two-fifths times as long as a Football field.
In other words, 520.97 feet is 1.44714 times the length of a Football field, and the length of a Football field is 0.691018 times that amount.(American) (total distance; per NFL regulation)
According to NFL specifications, an American football field should measure 360 feet from end to end. Because each team's goalpost is located at the far end of the scoring area (end zone), a ball on a scoring play may need to travel as many as 30 feet farther when kicked into the scoring area than when run (rushed) or passed into it.
It's about one-and-a-half times as long as a Football (Soccer) Pitch.
In other words, 520.97 feet is 1.51 times the length of a Football (Soccer) Pitch, and the length of a Football (Soccer) Pitch is 0.662 times that amount.(a.k.a. Football Field, a.k.a. Soccer Field) (field length, a.k.a. touchline distance)
According to the Laws of the Game, a football pitch should measure between 344 feet (when the Laws were originally, they used imperial measurements of 345 feet, and later converted to the metric units used today). The goal markess were defined as part of the pitch by the original rules of the game in the late 16th century, but it was not until the mid 19th century that the crossbar and the net were added
It's about one-and-seven-tenths times as tall as Big Ben.
In other words, the height of Big Ben is 0.59 times 520.97 feet.(officially the clock tower of Palace of Westminster, a.k.a. Houses of Parliament) (London, England)
The clock tower of the Palace of Westminster, which houses the bell known as "Big Ben," rises 310 feet. The tower has no elevator, and is therefore only accessible by climbing 334 steps to the top.
It's about one-and-seven-tenths times as tall as The Statue of Liberty.
In other words, 520.97 feet is 1.708 times the height of The Statue of Liberty, and the height of The Statue of Liberty is 0.5855 times that amount.(a.k.a. "Liberty Enlightening the World," a.k.a. La Liberté Éclairant le Monde) (Liberty Island, New York City, New York) (pedestal base to torch peak)
The Statue of Liberty reaches 305.1 feet including the pedestal. The statue was designed using an optical trick known as "forced perspective" to make the statue appear proportionally correct when viewed from its base and is, in actuality, disproportionately large at the top.
It's about half as long as The QE2.
In other words, 520.97 feet is 0.54 times the length of The QE2, and the length of The QE2 is 1.85 times that amount.(a.k.a. RMS Queen Elizabeth 2) The QE2 has a total length of 965 feet. During its voyaging lifetime from 1969 through 2008, it travelled more than 31,500,000,000 feet, the furthest cumulative distance by any ship in modern history.
