how tall is empire state building

The Empire State Building is about 1,454 feet tall (roughly 443 meters) when you include its antenna, and about 1,250 feet (around 381 meters) to the main roof.

Those two numbers both get used depending on the question: if someone asks “how tall is the Empire State Building to the tip?” they usually mean the higher figure with the antenna, while the lower figure refers just to the main structure/roof height.
