- Comparing
- Length ↔ Length
- Relative size
- The two selected measurements are approximately equal.
How to read the visual
The labelled spans and stored measurements determine the scale; unmeasured illustration details do not.
- Poppy seed is labelled example; treat the displayed value as a comparison anchor rather than false precision.
