Compare the figures

Each bar starts at zero. The longest bar is the highest value shown for that measure, not a rating.

Land areakm²

  2. India2,973,190 km²

Bars begin at zero and use one shared scale. This is a land-area comparison, not a score or recommendation. The source years are shown separately and may differ.

How the size ratio is calculated

The calculator converts each cited land-area value to square kilometres, then divides the larger area by the smaller. The difference is the larger value minus the smaller. It uses published area values, not pixels measured from the map outline.

For a broader comparison of land area, population, and calculated density, use the interactive country and U.S. state map. International state and province comparisons are not yet supported.
