Accurate visual scale

Each subject is rendered on the same baseline so the height difference looks proportional instead of decorative.

Height calculator plus chart

You can use HowHeight like a height calculator for cm and ft plus in, then keep the result on a visual comparison chart instead of stopping at a number.

People, animals, objects, and characters

The same board supports human height comparison, people height comparison, animal references, objects, and fantasy lineups on one scale.

Simple tool-first interface

The public page stays focused on comparison, not dashboards, onboarding funnels, or account-first framing.
