The study behind it
The figure comes from Khan et al., BJU Int, 2011, which measured 610 men. Method: measured by clinician.
This study did not record a bone-pressed measurement, which means it will read roughly a centimetre lower than a bone-pressed study of the same men. When you compare this row against a bone-pressed one, part of what you are seeing is the ruler.
A sample of 610 men puts this in the mid-range of the studies used here.
How it compares
United Kingdom ranks #12 of the 24 countries in the game. That is essentially the median of this list.
Both of those comparisons are against a list of two dozen countries chosen by which studies exist, not by any sampling of the world. Treat the rank as a fact about this dataset rather than a fact about the planet.

What this figure is not
It is not a description of any individual man from United Kingdom. The spread between individual men inside a single country is several times larger than the gap between any two countries on this list, which means a national average carries almost no information about a person.
It is also not medical advice or a benchmark to measure yourself against. If size is something you have been worrying about, the guide on what the pooled data actually shows is a more useful page than this one, and a doctor is more useful than either.
