Average Height in Ireland (Men & Women)

Ireland's average height

Ireland's people are tall by world standards and, in the most recent cohorts, slightly taller than their British neighbors. In the NCD Risk Factor Collaboration (NCD-RisC) estimates for the 1996 birth cohort, Irish men average 178.9 cm (5′10″) and Irish women 165.1 cm (5′5″). Men rank 20th of 200 countries and women 24th.

That modern ranking hides a dramatic history. Ireland in the 19th century went through the Great Famine of 1845–1852, which killed about a million people and drove as many to emigrate. Irish men born in 1896 ranked only 42nd in the world for height. Their rise to 20th over the following century is one of the clearer improvements among high-income countries.

How the estimates are built

NCD-RisC's 2016 study in eLife pooled 1,472 population-based studies with measured heights for more than 18.6 million adults. Self-reported data were excluded because people tend to overstate their height. A statistical model estimated the average height that each birth cohort reached at 18. The figures above describe Irish adults born in 1996, who turned 18 around 2014; earlier cohorts, shown in the next section, are shorter. Ireland was also one of 62 countries with vital registration more than 80% complete that NCD-RisC used to test how height relates to mortality. Across those countries, the authors found that gains in average height between cohorts were associated with lower mortality in middle and older age, one reason population height is treated as a marker of health and living conditions.

A century of Irish height

Irish men gained 12.5 cm across the century and Irish women 11.1 cm, both above the global gain of about 8 to 9 cm that Our World in Data reports. Men's progress was steady: about 4 to 5 cm in each of the first two thirty-year periods, then 2.2 cm and 1.1 cm in the two most recent twenty-year periods. Women's ranking dipped to 55th in the 1926 cohort before climbing to 24th by 1996.

Unlike many Northern European countries, Ireland did not stall between the 1976 and 1996 cohorts. Both men and women gained 1.1 cm over those two decades, while men in Sweden, Norway, Finland and the Netherlands gained nothing or slightly lost height. NCD-RisC notes that height gains plateaued for two to three decades in English-speaking countries like the United Kingdom; Ireland, in its estimates, kept growing slowly.

Height after the Great Famine

The Great Famine is central to Irish history, and researchers have looked for its traces in the bodies of those who lived through it and their descendants.

Famine skeletons from Kilkenny

In 2012, Geber and Murphy published a study in the American Journal of Physical Anthropology of 970 human skeletons discovered in mass burials from the height of the famine in Kilkenny City. The famine, they explain, began with a blight that wiped out the potato, virtually the only food of Ireland's poor and their main source of vitamin C. The skeletons showed widespread scurvy, which the authors concluded had indirectly influenced famine mortality. They also found a sex and stature bias: men and taller individuals had significantly more scorbutic lesions.

The Harvard survey: Irish born 1840–1910

The most important source on post-famine Irish height is the Harvard Anthropological Survey of Ireland, carried out in 1934–1936. Young, Relethford and Crawford used its data on 4,900 men and 1,430 women born between 1840 and 1910 to examine height in post-famine Ireland. Their 2008 paper in the American Journal of Human Biology found:

• Significant height differences among men by occupation, education and the socioeconomic status of their father and maternal grandfather.
• Men employed in agriculture, or whose fathers or grandfathers were, were significantly taller than other men.
• For women, only occupation and the grandfather's socioeconomic status mattered significantly.
• An inverse correlation between the British Cost of Living Index and men's heights: when living costs rose, men were shorter.

The authors concluded that access to resources played an important role in nutritional status, as reflected in final adult height.

Rural western Ireland in the 1930s

An earlier analysis of the Harvard data by Relethford and Lees, published in 1981, focused on 347 adult men and 261 adult women measured in western Ireland in the 1930s. After correcting for the height people lose with age, they found a general increase in men's stature over time, except for a sharp drop among people born around 1878, which affected both sexes. Women otherwise showed largely random variation. The authors proposed historical explanations involving differential migration and survival, a reminder that mass emigration could change who was left to be measured.

Irish children: a later growth spurt

Clinical growth standards for Irish children were published in 1987 by Hoey, Tanner and Cox. They measured a representative sample of 3,509 Irish children aged 5 to 19. Compared with other countries, Irish children had a significantly later pubertal growth spurt than children in either the UK or the US, yet their final adult height and weight were similar.

They also found that urban children were taller than rural children, and children from higher socioeconomic groups taller than those from lower groups, at all ages. But all groups ended up at the same final adult height, which suggests that by the 1980s the differences were mainly in the timing of growth, not in how tall children eventually became. The charts were similar to those of the UK but used colors to fit more information, making them more practical for clinical use.

Adults since 1990: taller, then heavier

The most recent evidence on Irish adults comes from four nationally representative nutrition surveys carried out between 1990 and 2024, analyzed by Donovan and colleagues in the European Journal of Nutrition in 2025. Across 4,357 adults, with measurements taken by researchers in three of the surveys and self-measured in the fourth, they found:

• Significant increases in mean height and weight between 1990 and 2011, for both men and women and for both adults aged 18 to 64 and those over 65.
• Obesity among 18- to 64-year-olds rose from 11.5% in 1990 to 23.7% in 2011, then fell to 17.3% in 2024.
• Mean weight and BMI decreased in the 2024 sample.

The authors cautioned that methodological differences between the surveys make the recent trend uncertain. The height increase between 1990 and 2011 is consistent with the NCD-RisC finding that Irish cohorts kept getting slightly taller later than many neighbors.

Ireland compared with its neighbors

Irish men are 1.4 cm taller than men in the UK, and Irish women 0.7 cm taller than British women. The comparison has reversed since the 1896 cohort, when UK men (166.9 cm) were 0.5 cm taller than Irish men. Ireland also now outranks the United States by 1.8 cm for men and 1.6 cm for women. In the 1896 cohort, American men were 4.7 cm taller than Irish men.

Ireland and Britain, cohort by cohort

The overtaking of the United Kingdom happened late and gradually. For most of the century, British men were slightly taller than Irish men; the crossover came between the 1956 and 1976 cohorts.

The decisive difference is the last twenty years of the series. British men gained nothing between the 1976 and 1996 cohorts, the plateau NCD-RisC describes for English-speaking countries, while Irish men added 1.1 cm. Irish women were actually slightly taller than British women in the 1896 cohort, fell behind in the middle of the century, and moved ahead again from the 1976 cohort.

Irish women: from 55th to 24th

The women's ranking has moved more than the men's. Irish women born in 1896 averaged 154.0 cm and ranked 42nd in the world. Thirty years later they had gained 4.3 cm, but other countries had gained more, and the 1926 cohort ranked only 55th. From there, Irish women climbed steadily: 43rd in the 1956 cohort, 35th in 1976 and 24th in 1996. Their gain over the last two decades of the series, 1.1 cm, matched the men's and was larger than that of women in the UK (0.6 cm), the Netherlands (a loss of 0.3 cm) or Sweden (a loss of 0.9 cm).

The gap between Irish men and women, 13.8 cm, is a little wider than the global gap of about 12 cm reported by Our World in Data for the same generation, and it has hardly changed since the 1956 cohort, when it was 13.3 cm.

Irish height in everyday terms

An average Irish man, at 178.9 cm, is about 5′10½″; an average Irish woman, at 165.1 cm, is about 5′5″. Actor Cillian Murphy, listed on this site at 172 cm (5′8″), is 6.9 cm shorter than the average Irish man of the 1996 cohort, which shows how wide the normal range of heights is within any country. Our World in Data notes that differences in height within a population are largely genetic, while differences between generations reflect nutrition and health. You can compare any two heights at true scale in the height comparison tool, or see where your height ranks with the height percentile calculator.

Summary

Irish men average 178.9 cm and women 165.1 cm, ranking 20th and 24th in the world. From a low point after the Great Famine, when Irish men born in 1896 ranked 42nd, height rose by more than 12 cm over the century and, unusually for Northern Europe, kept rising between the 1976 and 1996 cohorts. Famine skeletons, the 1930s Harvard survey, 1980s growth standards and national nutrition surveys since 1990 together trace how better resources made the Irish taller, overtaking both the British and the Americans.
