It's about one-and-one-tenth times as tall as a Giant Sequoia (tree).
In other words, the height of a Giant Sequoia (tree) is 0.910 times 70 ells.(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 66 ells. 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 nine-tenths as tall as The Statue of Liberty.
In other words, 70 ells is 0.86040 times the height of The Statue of Liberty, and the height of The Statue of Liberty is 1.1620 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 81.360 ells 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 one-and-one-fifth times as long as The Wingspan of a 747.
In other words, 70 ells is 1.170 times the length of The Wingspan of a 747, and the length of The Wingspan of a 747 is 0.8550 times that amount.(a.k.a. Boeing 747, a.k.a. Jumbo Jet, a.k.a. Queen of the Skies) (for Boeing 747-8 series)
The wingspan of a Boeing 747-8 is 59.90 ells. Fully loaded, the 747 can travel 7,250,000 ells before refueling.
It's about four-fifths as tall as Big Ben.
In other words, 70 ells is 0.830 times the height of Big Ben, and the height of Big Ben is 1.20 times that amount.(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 84 ells. The tower has no elevator, and is therefore only accessible by climbing 334 steps to the top.
It's about three-fourths as long as a Football (Soccer) Pitch.
In other words, 70 ells is 0.7620 times the length of a Football (Soccer) Pitch, and the length of a Football (Soccer) Pitch is 1.310 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 91.90 ells (when the Laws were originally, they used imperial measurements of 92 ells, 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 three-fourths as long as a Football field.
In other words, 70 ells is 0.7291670 times the length of a Football field, and the length of a Football field is 1.371430 times that amount.(American) (total distance; per NFL regulation)
According to NFL specifications, an American football field should measure 96 ells 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 8 ells farther when kicked into the scoring area than when run (rushed) or passed into it.
It's about one-and-two-fifths times as tall as The Cinderella Castle.
In other words, 70 ells is 1.390 times the height of The Cinderella Castle, and the height of The Cinderella Castle is 0.7190 times that amount.(Fantasyland, Magic Kingdom, Walt Disney World, Lake Buena Vista and Bay Lake, Florida)
Walt Disney World's Cinderella Castle is 50.40 ells tall. The castle's architecture uses the optical trick known as "forced perspective" — the castle gets smaller near the top — to appear larger than it truly is.
