It's about as long as The QE2.
It's about nine-tenths as tall as The Eiffel Tower.
In other words, 294,000 milimeters is 0.9070 times the height of The Eiffel Tower, and the height of The Eiffel Tower is 1.10 times that amount.(a.k.a. La Tour Eiffel) (Paris, France) (to flagpole peak)
The Eiffel Tower stands 324,000 milimeters tall, including its flagpole. The Tower is the largest structure in Paris as most other buildings are governed by a zoning restriction limiting them to a height of 37,000 milimeters or less.
It's about three-fourths as tall as The Empire State Building.
In other words, 294,000 milimeters is 0.771630 times the height of The Empire State Building, and the height of The Empire State Building is 1.2960 times that amount.(New York City, New York) (to top of building)

It's about one-and-three-tenths times as tall as The Golden Gate Bridge.
In other words, the height of The Golden Gate Bridge is 0.7690 times 294,000 milimeters.(San Francisco, California and Marin County, California) (height above water)
The height of each tower of Golden Gate Bridge is 227,000 milimeters 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 two-thirds as tall as The Petronas Twin Towers.
In other words, 294,000 milimeters is 0.65060 times the height of The Petronas Twin Towers, and the height of The Petronas Twin Towers is 1.5370 times that amount.(a.k.a. Menara Berkembar Petronas, a.k.a. Petronas Towers) (Kuala Lumpur, Malaysia) (to spire)
Each of the Petronas Towers stands 451,900 milimeters to their spires. Holding the record as the tallest buildings in the world from 1998 to 2004, the towers continue to hold the record for the deepest foundation barrettes — up to 115,000 milimeters deep.
It's about one-and-three-fifths times as tall as The Space Needle.
In other words, the height of The Space Needle is 0.6250 times 294,000 milimeters.(Seattle, Washington) (to aircraft warning beacon at peak)
Built for a 1962 World's Fair, the Space Needle stands 184,000 milimeters tall. With a track-and-wheel design inspired by railroad mechanics and a precisely-configured balance, the restaurant near the top of the space needle requires just a 1.5 hp motor to rotate at speeds of about 0.053 kph (0.033 mph).
