BBC Dimensions - How Big Is It Really?

BBC Dimensions, located at, is a neat tool for quickly comparing the size of famous objects and events to the size of your town, county, state, or country. BBC Dimensions runs on Google Maps. Here's how it works; pick one of the categories of objects or events then select an object and a small map will appear. Then enter your postal code or city name and BBC Dimensions will overlay your selected object over your city. Watch the Tekzilla video below to see BBC Dimensions in action.

This is what the Great Wall of China looks like when centered on my hometown.

Applications for Education
BBC Dimensions could be a useful tool for giving students a sense of the size of objects like the Three Gorges Dam or the size of Great Pacific Garbage Patch compared to their hometowns.
