What measurements does this comparison use?

The reference values used here are 2,376.6 km for Pluto (Diameter, average) and 3,474.8 km for The Moon (Diameter, average). The table links to background sources; natural objects and manufactured variants can differ from these reference values.

How should I read the drawing?

The Moon spans about 1.5× as much as Pluto across the longest side of each drawing. This is a linear scale comparison, not a comparison of mass or volume. For maps, the table reports area; doubling a map’s width and height multiplies its area by four.
