Average Height in the US, UK, and Canada Compared

The United States, United Kingdom, and Canada are often grouped together culturally, yet their populations show distinct height patterns shaped by genetics, immigration history, healthcare, and how data is collected. All three nations rank above the global average for adult height, but differences of a few centimeters between them can surprise people who assume "Western countries" are identical.

This article compares average stature for young men and women in each country, explains why numbers vary between studies, and shows how to check your own height against national and global benchmarks using Height Tools.

How average height is measured

Before comparing countries, understand what "average height" means in research:

Age: Most international comparisons use young adults around age 18–19, when growth has typically finished.
Sex: Men and women are reported separately because biological sex strongly affects height distributions.
Data source: National health surveys, military conscription records, and research consortiums (like NCD-RisC) may produce slightly different figures.
Self-report vs measurement: People often overstate height in surveys by 1–2 cm. Measured data is more reliable.

Our Average Height by Country dataset aggregates peer-reviewed sources and presents consistent figures for roughly 100 nations, including the US, UK, and Canada.

United States average height

For American men near age 19, measured averages typically fall between 175 cm and 178 cm (about 5′9″ to 5′10″) depending on the survey year and demographic breakdown. American women in the same age range average roughly 161–164 cm (5′3″ to 5′5″).

Regional and demographic variation

The US is large and diverse. Average height differs by:

Region: Some analyses show slightly taller averages in the Midwest and Plains states versus parts of the Southeast, though differences are modest.
Ancestry: European, African, Asian, and Hispanic heritage populations each carry different genetic height distributions. National averages blend these groups.
Socioeconomics: Childhood nutrition and healthcare access correlate with attained height across generations.

Historical trend

Average American height increased through much of the 20th century as nutrition and public health improved, then plateaued or slowed in recent decades for some groups, a pattern also seen in other high-income nations.

United Kingdom average height

British men at age 19 often average around 178 cm (5′10″) in national health data. British women average near 163–164 cm (5′4″).

The UK frequently ranks slightly taller than the US for men in cross-national studies, though the gap is small, often only 1–2 cm.

Possible explanations

Population genetics: Northern and Western European ancestry is common.
Healthcare: Universal NHS access from birth supports childhood monitoring (though height outcomes depend on many factors beyond insurance alone).
Diet patterns: Historically high dairy and protein intake in childhood (trends shift over time).

Canada average height

Canadian men typically average 175–179 cm, with women near 162–165 cm: broadly similar to the US but sometimes closer to Northern European figures for men.

Canada's immigration profile strongly influences national statistics. Large communities of European, South Asian, East Asian, African, and Latin American descent each contribute to the composite average. Urban centers like Toronto and Vancouver may differ from national means.

Side-by-side comparison

Country	Men (approx.)	Women (approx.)	Men (ft/in)
United States	175–178 cm	161–164 cm	5′9″–5′10″
United Kingdom	177–178 cm	163–164 cm	~5′10″
Canada	175–179 cm	162–165 cm	5′9″–6′0″

Differences between these three are smaller than differences between any of them and much of South or Southeast Asia, or between them and the Netherlands: often the tallest nation for men (around 183–184 cm).

How they rank globally

Among ~100 countries in our database:

All three sit in the upper half worldwide, often top 30–40% for men.
None match the very tallest European nations (Netherlands, Montenegro, Estonia).
All are considerably taller on average than nations facing long-term nutrition challenges.

Why cross-country comparisons are tricky

Different survey years

A 2010 US study and a 2018 UK study are not perfectly comparable without adjustment.

Inclusion criteria

Military-only samples skew male and sometimes healthier-than-average. School-based samples miss dropouts. Each method has bias.

Immigration timing

A country with recent immigration of shorter or taller populations will shift averages over decades independent of genetics changing in place.

Self-identification

Gender reporting in surveys evolves. Height research traditionally uses sex assigned at birth for biological growth charts.

Treat country averages as population statistics, not judgments about individuals.

Height and health: what averages cannot tell you

Taller populations sometimes correlate with better childhood living conditions at the national level, but individual height says little about personal health. Short adults can be perfectly healthy; tall adults can have medical conditions.

Pediatricians care about growth velocity and percentiles for children, not whether a country averages 175 or 178 cm.

Comparing yourself to US, UK, or Canada

Measure your height accurately (morning, shoes off, heels to wall).
Convert units if needed with our Height Converter.
Open the relevant country page or comparison tool.
Add your height alongside the national average or friends.

Example: If you are a 180 cm man in the US, you are above the male average (often 5–7 cm taller). In the Netherlands, 180 cm is closer to average for young men.

Tallest and shortest within North America

Don't forget internal diversity:

Basketball and volleyball select for height at elite levels, not representative.
Some indigenous and immigrant communities differ substantially from national means.
Second-generation children of immigrants often exceed parental height due to improved childhood nutrition, the immigrant height gap narrows over generations.

Data sources we cite

Practical takeaways

US, UK, and Canada all have relatively tall populations by world standards.
UK men often edge US men by a centimeter or two in many studies; Canada overlaps both.
Women's averages differ by similar small margins.
Individual height varies far more than these national gaps, any country has men above 190 cm and below 165 cm.

Browse all countries, drill into United States, United Kingdom, or Canada, and compare visually to see where you stand. Numbers are only part of the story, but they are a useful starting point for context.
