Chicago invented the modern skyscraper and - by the metric that matters - has largely resisted decorating them into dishonesty. Willis Tower, completed in 1974, carries a 6.7% Vanity Ratio and remains the most genuinely tall building the city has ever produced. It held the world height record for architectural top for 25 years; it would still be competitive on honest height today. The Skydeck observation deck on the 103rd floor at 412 metres is one of the most accurately-named observation decks in any major city.
Buildings ranked by Honest Height - the elevation of the highest occupied floor. Not architectural top. Not spires. Not decorative steel nobody rides an elevator to. The gap between the two is the Vanity Ratio. See the full methodology.

Top 3 in Chicago · Confirmed occupied height
The standard global ranking uses architectural top - the highest structural element regardless of whether anyone reaches it. The Honest Height ranking uses the highest occupied floor. For Chicago, the delta between the two metrics is tracked as the Vanity Ratio for each building.

Willis Tower was the tallest building in the world from 1973 to 1998. It still ranks 17th on the Honest 100 - a 50-year-old building, 412.4 metres of occupied steel, 6.7% Vanity Ratio. Chicago did not need to add a decorative crown to win. They just built the building.
