Average Height in Sierra Leone (2026 Data)
The average height in Sierra Leone is approximately 5'6" (168 cm) for men and 5'2" (158 cm) for women, based on NCD-RisC pooled height estimates.
Average Height in Sierra Leone: Men and Women
Adult height in Sierra Leone reflects genetics, childhood nutrition, healthcare access, and living conditions. Pooled international estimates provide the best available figures for current average adult stature.
For men, the population mean is about 168 cm (5'6"); for women, about 158 cm (5'2"). These figures represent adults aged 18 and older and are typically measured barefoot in health surveys.
Height varies by region, ethnicity, and birth cohort within Sierra Leone. The averages below describe the national picture; individual heights span a wide range above and below these means.
Average Height by Age Group in Sierra Leone
| Age Group | Men (cm / ft-in) | Women (cm / ft-in) |
|---|---|---|
| 18–25 | 170 cm (5'7") | 159 cm (5'3") |
| 26–35 | 169 cm (5'7") | 159 cm (5'3") |
| 36–50 | 168 cm (5'6") | 158 cm (5'2") |
| 50+ | 167 cm (5'6") | 157 cm (5'2") |
Age-group estimates derived from NCD-RisC pooled height estimates. Younger cohorts typically measure slightly taller than older groups due to secular height trends.
How Sierra Leone Compares to the World and the US
Globally, the approximate mean adult height is about 171 cm (5'7") for men and 159 cm (5'2.5") for women, based on NCD-RisC pooled estimates. Compared to this, Sierra Leone men are 3 cm shorter than the global male mean and women are 1 cm shorter than the global female mean.
The United States averages about 175 cm (5'9") for men and 162 cm (5'4") for women (CDC/NHANES). Sierra Leone men are 7 cm shorter than US men on average; Sierra Leone women are 4 cm shorter than US women.
Sierra Leone's averages reflect West African ancestry and recovery from conflict-era nutrition setbacks.
Why Heights Differ: Genetics, Nutrition, and Trends
Height is roughly 80% genetic and 20% environmental, but nutrition in the first years of life matters enormously at the population level. Sierra Leone's averages reflect West African ancestry and recovery from conflict-era nutrition setbacks.
Like most populations, Sierra Leone has seen height changes across generations as nutrition, sanitation, and healthcare evolved.
Comparing your personal height to Sierra Leone's average is informative, but percentile rankings depend on which reference population you use. Our calculator compares against US CDC/NHANES data, which may differ from Sierra Leone's national distribution.
