How to Use this Planet Size Comparison Generator

The tool is actually quite easy to use. You just need to choose a planet from the dropdown list and add it to the chart for size comparison. With respect to removing any figure, you can achieve that under the ‘Remove’ tab.

Please note also you can modify the position of any figure on the chart by dragging.

It’s worth noting there is a maximum number of 5 figures that can be added to the chart. Of course, you can always remove existing figures if you reach the limit and want to add new ones.

In order to get the best visual results for comparing planet sizes, try to do the following:

  • When using a mobile device, make the view horizontal (i.e. landscape orientation)
  • Access the tool from a computer or large tablet if at all possible

The tool will allow you to compare the size of all 8 planets and 4 dwarf planets in the solar system.

All planet images used are colorful illustrations rather than real photos. And they appear to have been drawn pretty accurately.

We didn’t include the sun because it’s far bigger than any other planet, so there is no comparison really.

Please note that the size of planets (radius) was retrieved from Wikipedia.

Conclusion

Whatever planets you want to compare the size between, this accurate online tool will help you out. You just need to choose and add the desired planets to the chart.

It’s worth mentioning the chart axis shows the height measurement in both metric (i.e. kilometers) and imperial units (i.e. miles). So, you won’t need to worry about unit conversion.

Feel free to let us know if you find any size that’s inaccurate so we can correct it. Also, we would love to hear any suggestions or questions about this planetary tool.
