Countries by Coastline
Methodology
This is based on original research by me, the JetPunk quizmaster. I wrote a script to calculate the coastline of each country based on this original data source from Natural Earth.
Notes
- This does not include lakeshore
- It does, however, include oceanic seas and inlets such as the Black Sea, Mediterranean Sea, Puget Sound, etc..
- It does not include the Caspian Sea
- The coastline for Israel does not include Gaza
- The coastline for each country includes overseas regions, dependencies, and autonomous areas. For example, the number for Denmark includes Greenland.
- The length of coastline depends on the resolution of the data source. The higher the resolution, the longer the coastline.
- The source data is not 100% perfectly accurate but it is, in my opinion, the best data source available

Croatian sources say 526 km in a straight line, 1777 along the mainland coast and 5835 km with islands (74% of Adriatic coast)
Slovenia is usually given between 42 and 48, most often as 46.6 km. Especially when it's so small, it's easy to look at a detailed map or satelite photo and wonder why this bay or that wouldn't be included – in this blog you can see an image illustrating how you can arrive at different values. Further complicated (at this scale) by the port piers/docks and salt ponds.
