General

1.   What is the world's tallest building?

Burj Khalifa, also known as Burj Dubai, in Dubai, United Arab Emirates.

This diagram shows the historical world's tallest buildings.


2.   How tall must a building be in order to be considered a skyscraper?

Since the term was first used in the late 19th century, buildings of 12 storeys or more have been considered skyscrapers.


Building Data

3.   How can I submit new information or corrections?

There is a special section of the forum for this, submit new information & corrections. Review the guidelines posted there.


4.   How are building heights defined and measured?

Some building heights include mechanical penthouses, and some do not. We do not know which buildings use which form of measurement unless something tells us. Many building heights that are recorded do not follow a specific standard of measurement, so we really have no way of knowing for every building (there putting into question the validity of comparing buildings by heights, or at least the heights we use).


5.   How is official height determined?

The official height of a building is the maximum of the roof and/or spire heights.

If a building does not have a spire, such as the Sears Tower, then its official height is its roof height.  If a building does have a spire, such as the Petronas Towers, then its official height is its spire height.


6.   Are estimated heights used?

Estimated building heights are used, but they are not displayed at all. Because of the visual comparison between buildings in the diagram it is usefull to use estimated heights for some buildings.

For example, we have the roof height of the Petronas Towers estimated at 425 meters so that if a diagram is sorted by roof height these buildings are put in the proper position. It would be no use to anyone to know that we estimate the roof at this height, so we do not display our estimates.

It would be incorrect for us to display the estimated heights because we only want to display accurate information, and do not want to spread inaccurate information.


7.   Why isn't there an approved status category?

We have chosen not to differentiate between proposed and approved buildings/projects because when a project is approved by government, it is still essentially a proposed project and does not necessarily have a better chance of being built.  It is still a proposed project until constuction begins.

There may also be several levels of government which must approve a project, making it difficult to know when all levels have given approval.


8.   Can you give me more information on a certain building?

No, all the information we have is already listed in our database.  If you can't find the information you want here, try asking in our discussion forum.


9.   Where do we get building data from?

Most of the information we have comes from other websites, city hall websites and planning departments, and books.


10.   Can I download or purchase a custom set of building data?

We do not offer this service.


Diagram

11.   How can I print a diagram?

We do not allow printing of our diagrams.  If you would like a printed copy of our work please purchase one of our posters.


12.   Can I obtain a license to use your material?

Please see the Commercial License Inquiry page.


13.   How can I add my drawings to the diagram?

The drawing submission system is in an early stage of development right now. You can add drawings if you are logged-in.

Find the building in the diagrams which you want to add a drawing of, and click on its image to open a new window. On that page will be a link to "Add new drawing".

There is no way to add a new buildings yet, you can only add new drawing for buildings which already exist in the database.
