The shortest average height in the world is found in Timor-Leste (East Timor), a small nation in Southeast Asia. Adult men there average about 62.3 inches (158 cm) tall, and adult women average about 59.1 inches (150 cm). These figures come from a large global analysis of height trends published in the journal eLife in 2016, which pooled data from over 1,400 studies worldwide.
What Country Has The Shortest Average Height
Timor-Leste holds the top spot for the shortest average height in the world. The country sits on the island of Timor, northwest of Australia. Its population has experienced decades of political instability, food insecurity, and limited healthcare access — all factors that influence childhood growth and adult stature.
Other countries with very short average heights include Laos, Papua New Guinea, and several nations in South Asia and sub-Saharan Africa. But no country currently documented has a lower average adult height than Timor-Leste.
The global average height is about 69 inches (175 cm) for men and 63 inches (160 cm) for women. That means the average man in Timor-Leste is roughly 13 cm (about 5 inches) shorter than the global average for men.
Why Are People In Timor-Leste Shorter Than Average?
Height is not determined by genetics alone. Environment matters enormously, especially in the first few years of life. The clearest explanation for Timor-Leste’s short stature is childhood malnutrition and a high burden of infectious disease.
When a child does not get enough calories, protein, zinc, and other key nutrients, growth slows. If this happens during the first 1,000 days of life — from conception to age two — the height deficit is largely permanent. The body prioritizes survival over linear growth when resources are scarce.
Timor-Leste has one of the highest rates of childhood stunting in the world. Stunting is defined as being more than two standard deviations below the median height-for-age of a healthy reference population. In Timor-Leste, roughly half of all children under five are stunted, according to UNICEF data. That means the growth deficit starts early and carries into adulthood.
Infectious disease also plays a role. Repeated bouts of diarrhea or respiratory infections divert energy away from growth. Poor sanitation and limited access to clean water increase the frequency of these infections. The combination of undernutrition and infection creates a cycle that suppresses height gain.
Is Genetics A Factor In National Height Differences?
Genetics sets a range of potential height for each individual. But that range only becomes reality if nutrition and health conditions allow it. Within a single country, taller parents tend to have taller children. Across countries, however, environmental factors often explain more of the difference than genetics does.
Studies of migrants and siblings provide strong evidence for this. Children who move from low-income countries to higher-income countries at a young age often grow significantly taller than their peers who remain behind. The same genetic background produces very different heights depending on environment.
So while the people of Timor-Leste do carry genetic variants that influence height, their short average stature is primarily a reflection of living conditions. If nutrition and healthcare improved dramatically, average height in Timor-Leste would likely increase over several generations.
How Does Height Change Over Generations?
Height is not static. It changes with economic development, nutrition, and public health. The same eLife study that identified Timor-Leste as shortest also showed that many countries gained several centimeters per decade through the 20th century.
For example, South Korea saw one of the largest height increases in the world. As the country industrialized and diets improved, average height climbed sharply over the course of a few decades. This demonstrates how quickly height can respond to environmental change.
In contrast, some countries have seen height stagnate or even decline. The United States, for instance, has seen a plateau in average height since the mid-20th century, despite continued economic growth. This suggests that once basic nutrition is adequate, further gains become smaller and more dependent on other factors like healthcare quality and social equality.
For Timor-Leste, the path to taller average height runs through better childhood nutrition, improved sanitation, and expanded healthcare access. These are the same factors that drove height increases in countries that developed earlier.
What Other Countries Are Among The Shortest?
Timor-Leste is first, but several other nations have average heights that are only slightly taller. Knowing these can help put the global picture in perspective.
- Laos — Men average about 62.4 inches (158.5 cm); women about 58.7 inches (149 cm).
- Papua New Guinea — Men average about 62.6 inches (159 cm); women about 59.4 inches (151 cm).
- Guatemala — Men average about 63.2 inches (160.5 cm); women about 59.1 inches (150 cm).
- Bangladesh — Men average about 63.8 inches (162 cm); women about 59.8 inches (152 cm).
- Nepal — Men average about 63.9 inches (162.3 cm); women about 59.9 inches (152 cm).
These numbers come from the same global height analysis. The pattern is consistent: countries with higher rates of childhood malnutrition and poverty tend to have shorter average heights. Geographic region is less important than living conditions.
It is worth noting that some Central American countries like Guatemala also rank near the bottom. Indigenous populations in Guatemala have experienced generations of poverty and food insecurity, which shows up clearly in height data.
Does Short Average Height Affect Health?
Short stature itself is not a disease. Many people of short stature are perfectly healthy. The concern is what short average height indicates about a population’s overall health and development.
Childhood stunting is linked to more than just height. Stunted children tend to have lower cognitive development scores, weaker immune function, and higher risk of chronic disease later in life. These outcomes are not caused by being short — they are caused by the same malnutrition and infection that stunted growth in the first place.
At the population level, average height is sometimes used as a proxy for human development. It reflects how well a society meets the basic needs of its children. When a country like Timor-Leste has very low average height, it signals that many children are not getting adequate nutrition during critical developmental windows.
For an individual, being shorter than average does not mean poorer health. The relationship between height and health is complex and context-dependent. Taller people have slightly lower risk of heart disease but slightly higher risk of some cancers. These differences are small and not clinically meaningful for most people.
Can Average Height In Timor-Leste Increase?
Yes, but change takes time. Height improvements happen over generations, not years. The key interventions are well understood: maternal nutrition before and during pregnancy, exclusive breastfeeding for the first six months, adequate complementary feeding from six months onward, and treatment of childhood infections.
Improving sanitation and access to clean water reduces the infection burden. Vaccination programs prevent diseases that sap growth. Social safety nets that reduce extreme poverty help families afford better food. All of these measures have been shown to reduce stunting in other countries.
Some progress has already been made. Timor-Leste’s stunting rate has declined from extremely high levels in the early 2000s, though it remains among the highest in the world. The country’s health system is young and under-resourced, but international aid and national programs are working to address malnutrition.
It is important to be realistic about timelines. A child who is stunted at age two will not catch up fully in later childhood. The gains come from preventing stunting in the next generation of babies. That means the full impact of better nutrition today will be visible in adult height statistics roughly 20 years from now.
Frequently Asked Questions
What is the average height in Timor-Leste?
Adult men in Timor-Leste average about 158 cm (62.3 inches), and adult women average about 150 cm (59.1 inches). This is the lowest national average documented in global height studies.
Why are people in Timor-Leste so short?
High rates of childhood malnutrition and infectious disease are the main causes. Stunting during the first two years of life permanently limits adult height.
Is Timor-Leste the shortest country in the world?
Yes, according to the most comprehensive global height analysis, Timor-Leste has the lowest average adult height of any country. Laos and Papua New Guinea are close behind.
Can average height in a country increase?
Yes, average height increases when childhood nutrition, sanitation, and healthcare improve. South Korea and Japan showed large height gains in the 20th century as living conditions improved.
