Gaoloumi dose not overestimate,their database underestimates because it has not been updated for a long time,in every city forum,data is very accurate because they were all locals and there are strict rules.
But as I have said,most cities forum don't statistical 150m-,big cities don't statistical 200m-,so there is no database about buildings 100m+ except for some small cities
And as far as I know,the Chinese government has not released official detailed data

I commend Isaidso for his efforts, but so many cities these days have buildings over 300m+ that I think it is just too overwhelming to try to count them and there are so many that they really do not stand out in a skyline these days. In today's big city skylines around the world, a skyscraper has to be at least 150 meters to even be noticed. That is why I prefer sticking to the 150 meter criterion.

I absolutely hate here in Miami when another developer puts up another condo that's less than 150 meters, especially when they are only a meter shy of it.

How about starting a new thread to count 200m+ (real skyscraper) only?

# of 200m+ Buildings Completed, U/C, Proposed

I think at 150m+ you can still get a good sized forest without having too many skyscrapers to count. I think starting at 200m+ cuts out a lot of skyscrapers in a lot of cities. What makes 200m+ a real skyscraper anyway? Is that your own personal criterion?

So lets start a new thread for 150m+ then.

SSC criteria

over 300m = supertall
200- 299m = skyscraper
100- 199m = highrise

The possibility of getting an accurate list is 0.00000000000001%. Why are people kicking off??

How was this established? Where is this printed?


Definition: A skyscraper is defined on Emporis as a multi-story building whose architectural height is at least 100 meters.

True! Even here in Miami, for instance, there are buildings that we know exceeded their original heights specifications and others that didn't meet their original height specifications, but we have no way of nailing down what height the building actually is. In cases where buildings exceeded the height specification for which they were approved, there might even be a penalty involved if the actual height of the building became known, especially in cases where the Federal Aviation Administration had to give approval.

What I don't understand is that the information must exist somewhere. Even in China, cities would know what buildings exist in their jurisdiction. When buildings go up the city would know how tall it is. How would they not? It's surely a matter of the information being kept in private and/or government hands.

What do you mean? If Miami wasn't mentioned till page 6 that was because there are about 100 cities to document, not bias for one over another. Was I supposed to do it all in one day? Do you have any idea how much work this thread was? There's a reason I haven't updated in ages, it became too much for me.

I think there is no official definition or height above which a building may be classified as a skyscraper. Different websites, organizations and even countries/cities follow different criteria to classify skyscrapers (taliking about height). Ten years ago a 12 storey or 35 meter building was considered as skyscrapers. Now some websites and cities considers only 200m+ as skyscrapers. In some small cities a 20 storey building is considered a skyscraper, but in big cities even a 40 strey building may not be called a skyscraper.

A skyscraper is a tall, continuously habitable building of many storeys, usually designed for office and commercial use. There is no official definition or height above which a building may be classified as a skyscraper.

The term "skyscraper" was first applied to buildings of steel framed construction of at least 10 storeys in the late 19th century, a result of public amazement at the tall buildings being built in major cities like Chicago, New York City, Philadelphia, Detroit, and St. Louis.[8] The first steel frame skyscraper was the Home Insurance Building (originally 10 storeys with a height of 42 m or 138 ft) in Chicago, Illinois in 1885.

A loose convention of some in the United States and Europe draws the lower limit of a skyscraper at 150 m or 490 ft.

I don't know whether it is printed somewhere or not but this is the standard method SSC is following over the years to classify buildings/projects which you can see in their homepage.

So i will go by SSC (200m-299m).

Sorry Isaidso, but I was confused by how you were going about this. Yes, I can imagine how much work it was.

According to Wikipedia and some others sites, a skyscraper is a building with at least 15 floors, or at least 100 meters, but there isn't any accurate estimates for the height of a skyscraper.

Yes, the information must exist somewhere,but the problem is wether there is authority for statistics
China Bureau of Statistics is not CTBUH.They are not responsible for statistics and published the number of 100m+
For example:The People's Republic of China Ministry of Housing and Urban-Rural Development,they publish a lot of official information,such as China Construction Yearbook,hundreds of pages,but they don't count the number of 100m+l

Maybe a private Chinese citizen will take it upon himself/herself to publish a comprehensive data base one day.

That would be nice. I don't think we have anywhere near the full story on Shanghai and Shenzen.

To be honest I totally agree. It's hard to keep up with London's proposals let alone somewhere like Shenzhen, Shanghai etc.

I think it's a case of doing the best you can with the data you can then.
