Methodology & Editorial Standards
HowHeight uses the chart value shown in each visualization as the base measurement, then standardizes that value into centimeters and feet/inches for consistent reading across pages.
Each landmark page uses two images: the original height chart and the human comparison chart. The page copy stays focused on visual comparison, source clarity, and the exact chart value shown in the image.

What a chart value means
A chart value is the landmark height shown in the visualization. The same height is displayed in centimeters and feet/inches so you can compare landmarks using either unit.
Why there are two chart images
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.
Source handling
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 rules
Changes to a landmark’s stated height or source information may require a revision to its chart and accompanying explanation.
The “Last updated” date shows when the page information was revised. It does not indicate when the landmark was last measured.
Editorial ownership
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.
Comparison rules
Compare landmarks using the displayed chart values and units. Check the source notes when comparing figures from different references, as they may use different measurement points.
The centimeter and feet/inch figures are two ways of expressing the same chart height, so changing units does not change the height being compared.
