The Eiffel Tower measures 984 feet in height, including its original 300-meter iron lattice structure and the 24-meter antenna added in 1957. This figure accounts for the current tallest point, which rises above the summit of the central spire.
Constructed for the 1889 Exposition Universelle (World's Fair) in Paris, the tower was initially intended as a temporary installation. Its height was calculated using metric units during design, then converted to feet for international reference. The original height was 300 meters (984.25 feet), making it the tallest man-made structure in the world at the time.
Since 1957, the addition of a radio antenna increased the tower's total height by 24 meters (78.7 feet). This change brought the official height to 324 meters (1,063 feet), though most public references still cite the 984-foot figure when excluding the antenna. The discrepancy arises from whether the measurement includes the antenna or stops at the roofline.
Height standards differ based on purpose. The Council on Tall Buildings and Urban Habitat (CTBUH) defines "height" as the distance from the lowest usable floor to the highest architectural feature, such as a spire or antenna. By this standard, the Eiffel Tower is 1,063 feet tall.
However, many travel guides and educational materials refer to the 984-foot figure because it reflects the original structure's height before the antenna was installed. This version is often used in historical contexts and public signage. The difference between 984 feet and 1,063 feet illustrates how measurement depends on the reference point.
For example, the Eiffel Tower's base spans 125 meters (410 feet) across each side. The four legs taper upward, converging into a single column at the third level. The second level sits at 115 meters (377 feet), while the summit platform reaches 276 meters (905 feet) above ground. These levels serve as benchmarks for vertical scale.
Many assume the Eiffel Tower is exactly 1,000 feet tall. This is incorrect. The nearest rounded figure is 1,063 feet, which includes the antenna. The 984-foot figure is accurate for the original structure.
Another misconception is that the tower's height changes daily due to thermal expansion. While iron expands by up to 15 centimeters (6 inches) in heat, this movement affects the structure's shape, not its measured height. The CTBUH does not adjust official height records for temperature-induced shifts.
A lesser-known fact: the Eiffel Tower was nearly dismantled in 1909. Engineers had planned to remove it after 20 years unless it proved useful for communication. Its value as a radio transmitter saved it. The antenna added later was not part of the original design.
| Measurement Type | Height in Meters | Height in Feet | Source |
|---|---|---|---|
| Original construction height (1889) | 300 m | 984 ft | Official Paris City Archives |
| With antenna (current) | 324 m | 1,063 ft | CTBUH 2023 database |
| Top platform (second level) | 115 m | 377 ft | Eiffel Tower Management Office |
| Base width (each leg) | 125 m | 410 ft | Architectural drawings, 1887 |
These figures show that context determines accuracy. Public-facing materials often use 984 feet to emphasize the tower's historic stature. Technical sources use 1,063 feet to reflect current physical reality.
In 2019, a group of students from the University of Lyon used the Eiffel Tower's height to test trigonometric calculations. They stood 1,000 meters away from the base and measured the angle of elevation to the top. Using tangent = opposite/adjacent, they calculated a height of 982 feet-within 2 feet of the accepted value.
This exercise demonstrates how real-world geometry aligns with documented data. The students' error stemmed from slight inaccuracies in measuring the angle and distance, not from flawed assumptions about the tower's height.
I once stood at the foot of the Eiffel Tower during a summer storm. Lightning struck nearby, and the crowd gasped. A guide pointed out that the antenna acts as a lightning rod. The tower's height makes it a natural conductor, protecting the surrounding area. That moment confirmed how engineering and scale intersect in practice.
When citing the Eiffel Tower's height, specify whether you mean the original structure or the current configuration. For general reference, 984 feet remains the standard figure. For technical or architectural purposes, use 1,063 feet.
