How big is that iceberg, really?
Icebergs and glacier-calving events are reported in square kilometres or compared to cities, and both are hard to picture. Enter an iceberg's area (or its length and width) and this tool places it next to familiar references, from Manhattan to whole parks, so the scale finally clicks.
For context, read how a Manhattan-sized block broke off Greenland's Petermann Glacier in our explainer on the calving.
Common questions
How do you measure an iceberg's size?
Usually by surface area in square kilometres, estimated from satellite images. You can also multiply an approximate length by width, which this tool accepts.
Why compare icebergs to cities?
A number like 130 km² means little on its own. Placing it next to a city or park you know turns the figure into something you can actually picture.
A schematic comparison for scale. Real icebergs are irregular and extend far below the waterline.
