It's about as tall as The Statue of Liberty.
In other words, the height of The Statue of Liberty is 1.004 times 38 lengths.(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 38.140 lengths 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 as tall as Big Ben.
In other words, the height of Big Ben is 1 times 38 lengths.(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 39 lengths. The tower has no elevator, and is therefore only accessible by climbing 334 steps to the top.
It's about nine-tenths as long as a Football (Soccer) Pitch.
In other words, 38 lengths is 0.8820 times the length of a Football (Soccer) Pitch, and the length of a Football (Soccer) Pitch is 1.130 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 43.10 lengths (when the Laws were originally, they used imperial measurements of 43.10 lengths, 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 four-fifths as long as a Football field.
In other words, 38 lengths is 0.8444440 times the length of a Football field, and the length of a Football field is 1.184210 times that amount.(American) (total distance; per NFL regulation)
According to NFL specifications, an American football field should measure 45 lengths 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 3.750 lengths farther when kicked into the scoring area than when run (rushed) or passed into it.
It's about one-and-one-fifth times as tall as a Giant Sequoia (tree).
In other words, the height of a Giant Sequoia (tree) is 0.830 times 38 lengths.(a.k.a. Sequoiadendron giganteum, a.k.a. Sierra redwood, a.k.a. Wellingtonia)
Giant Sequoias of the Giant Sequoia National Monument located in Sierra Nevada, near Visalia, California can grow to heights of 31 lengths. The wood from the Giant Sequoias is often brittle and prone to shattering when such trees are felled, and as a result the trees logged in the late nineteenth century were often usable only as shingles or matchsticks.
It's about one-and-one-third times as long as The Wingspan of a 747.
It's about seven-tenths as tall as The Great Pyramid of Giza.
In other words, 38 lengths is 0.710 times the height of The Great Pyramid of Giza, and the height of The Great Pyramid of Giza is 1.40 times that amount.(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 53 lengths. 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.
