Which measurement is bigger?
The recorded diameter of Jupiter is 11.209 times the recorded diameter of Earth. The selected measurements are 142,984 km and 12,756 km, respectively.
| Object | Metric size | Imperial size | Dimension |
|---|---|---|---|
| Jupiter | 142,984 km | 88,846.1 mi | diameter |
| Earth | 12,756 km | 7,926.2 mi | diameter |
What this comparison measures
Inspect NASA’s equatorial diameters on one shared scale. Jupiter is flattened by rotation, so its equatorial diameter differs from the mean-diameter figure you may have seen elsewhere.
Jupiter: Equatorial diameter; mean diameter would be smaller.
Earth: Rounded equatorial diameter; the polar diameter is slightly smaller.
The drawings use the same physical scale, but are simplified illustrations. They show a selected linear dimension rather than mass, surface area or volume. The space between objects makes the comparison readable and does not represent a real-world separation.
Inspect the sources
Both measurement sources are linked below the interactive board. The individual Jupiter entry and Earth entry provide the selected conventions and related objects.
Change either selection to explore another pair. The full size comparison tool also lets you enter a personal height. To practise estimating rather than reading the answer first, try the daily five.
