How to use the country height reference tool
Start by choosing a country, selecting women or men, and entering your height. The summary shows your height, the selected country reference, the numeric gap when a value exists, and whether that country is part of the audited adult-source ranking.
The country selector deliberately shows source status. Audited adult sources are the cleanest comparison rows. Limited adult candidates can still be useful but carry caveats. NCD-RisC fallback rows are age-19 estimates, not all-adult averages. Missing rows remain unavailable instead of being filled from weak snippets.
Use the on-page visual chart when you want to explain the result. It places your height beside the available country references on one baseline, while the source details below the summary keep age range and method visible.
Source Standard
HowHeight data source standard
HowHeight prioritizes accuracy. Values are selected from official or authoritative public sources whenever possible, then checked against the most recent reliable public material we can find. Source URLs stay attached to the record.
Official national health surveys, government statistics, public health agencies, and clearly documented research sources are preferred over snippets or copied aggregator numbers.
When a strict adult source is not available, the page labels the row as a limited candidate, 19-year-old fallback, or missing value instead of hiding the limitation.
Expanded FAQ
Expanded FAQ
- What should I trust first?
- Prefer rows labeled as audited adult sources, then read the age range, measurement method, year, and source URL before comparing countries.
- Why not fill missing countries with a quick web answer?
- Weak snippets often hide age range, method, and original source. Missing values are safer than false precision.
- Can two sources give different values for the same country?
- Yes. They may measure different ages, survey years, methods, or populations. This page keeps those fields visible so the difference is explainable.
- Does unit switching change the source?
- No. Centimeters and feet plus inches are display formats for the same selected reference value.
- Can this tool assess a child or teenager?
- No. Use the height percentile calculator for age-specific child or teen reference charts.
