A little more perspective
A person can almost disappear beside a skyscraper. That is the scale doing its job. Zoom in to find the person again: making the figure artificially larger would change the comparison you came to explore.
For a classroom activity, predict the ratio first, then divide the taller height by the shorter one. Keep units consistent, record your chosen height, and explain that the figure is an illustration rather than a photograph of you.
Quick facts
A 1.75-metre reference person. Use “Add yourself” to enter your own height. This is a reference value, not a claim about the global average.
For a presentation or a research note, include the subject, the measurement definition, and the assumed measurement. A picture alone cannot explain those choices. The comparison guide explains how to export an image and its source notes together.
Sources and measurement notes
The default human height is a configurable reference chosen for the tool. It is not a sourced population average.
