Methodology & Editorial Standards

A HowHeight chart value is the landmark height displayed in the visualization. The editorial page does not invent a separate measurement layer. It presents the chart value clearly, then formats it in cm and feet/inches so users can compare landmarks without switching units.

The original height chart shows the landmark on its own terms. The human comparison chart adds visual scale, so the chart reads more quickly at a glance. The second image is for human-scale comparison only. The copy does not publish a numeric human comparison value.

HowHeight uses public reference materials together with editorial compilation. When a value is based on the chart visualization, the page says so directly. The site does not claim first-hand measurement where it does not have it, and it does not invent official sources to fill gaps.

Prepared by HowHeight Editorial. Source language is standardized across the library so the reader can see when a page is chart-led rather than tied to a single institutional publication.

Update the page when chart values, image assets, or normalization rules change. Keep the JSON source of truth, the visible page copy, and the image files aligned. Each landmark page keeps one canonical URL, and utility variants stay out of the index.

Last updated dates are carried at the page-data level so the rendered page, sitemap entry, and editorial record move together.

Prepared by HowHeight Editorial. The site follows a documented editorial workflow rather than ad hoc content updates, so each page can be reviewed, revised, and updated in a controlled way.

Page copy uses human comparison chart language. The tone stays factual and restrained. The goal is to make the chart readable, not to add extra claims or filler around it.

Method language is also fixed: the page uses the chart value shown in the visualization, then standardizes it into centimeters and feet/inches for consistent comparison.
