Their steel construction allows for normal swaying without endangering the building’s structural integrity nor the occupants inside. While some might find it unsettling to notice a tall building swaying in the wind, this natural movement is no cause for concern and actually means the skyscraper is working as designed.
Why Do Skyscrapers Sway in the Wind?
Because skyscrapers are so tall, their architects must be very precise in keeping the buildings upright. Skyscrapers are specifically designed to withstand extreme weather and geological events such as high winds or earthquakes. Allowing for movement helps these tall buildings sway and alleviate wind pressure, minimizing any fall risk.
In fact, most city skyscrapers are designed to stand tall against 100 mile-per-hour winds, with only slight movement detected from inside. Even during the windiest Chicago days, Skydeck visitors may not even feel the sway, noticing movement only through outdoor visual clues like flapping flags or leaves in the air.
How Much Do Skyscrapers Sway?
The height, location, and wind speed surrounding a skyscraper help determine how much it will sway. The higher the floor, the more apparent the building’s swaying will be. For example, the world’s tallest building—the Burj Khalifa in Dubai—can experience up to two meters in back-and-forth sway from its 163rd floor. Comparatively, the Willis Tower has 110 floors so it doesn’t sway as much.
Most skyscraper visitors won’t notice how much skyscrapers sway, as the movement is designed to be as imperceptible as possible. That being said, individuals who experience motion sickness may be more aware of tall buildings swaying and may need to move to a lower floor to eliminate the swaying sensation.

Plan a visit to Skydeck today to see if you can feel a skyscraper swaying in the wind!
Why do skyscrapers need to sway in the wind?
Skyscrapers are designed to sway slightly to absorb wind forces. If they were completely rigid, the stress could cause structural damage. Swaying helps the building distribute energy safely. It’s a natural part of how tall structures are engineered.
How much can a skyscraper move without people noticing?
Most skyscrapers can move a few inches to several feet at the very top, depending on height. Engineers ensure this movement is slow and controlled so most people don’t notice it. Occupants may feel slight motion during extreme wind conditions. For safety, the sway is always kept within engineering limits.
What design features keep skyscrapers safe when they sway?
Engineers use tuned mass dampers, flexible materials, and wind-resistant shapes. These features absorb and reduce movement during storms. Building codes require skyscrapers to meet strict sway limits. Together, these elements keep tall buildings both safe and comfortable.
