How big is Mount Rainier?

Elevation comparisons share sea level as a datum rather than a local valley floor.
Put the measurement in perspective
The recorded height is 0.71 times the height of Denali (6.19 km). This is a ratio of the labelled linear dimensions. It does not describe weight, area or volume.
Use the interactive comparison to see both drawings on one shared scale. You can choose another reference or enter your own height. If the sizes are very far apart, the smaller object may be almost invisible; an intermediate reference makes the progression easier to inspect.

The note above explains the specific value selected. Drawings are schematic; the stated measurement determines the scale. Report a measurement issue.
Check the convention
Summit elevation is relative to sea level; tree height and waterfall drop use a local vertical reference. The entry’s measurement note specifies which quantity is being compared.
