Size matters as cities compete for tallest building crown
13 November 2013 Last updated at 02:56 GMT
A committee of architects has declared New York City's newly erected One World Trade Center the tallest building in the US, at 1,776ft (541m).
The Height Committee of the Council on Tall Buildings and Urban Habitat announced its decision in Chicago. The previous title holder was that city's tallest building, the Willis Tower, at 1,451ft (442m).
The committee ruled a 408ft needle at the top of One World Trade Center counted toward its height. The BBC spoke to people in both cities to find out whether size matters.
