Is 5'6 Tall for a Man?

How 5'6 Compares to US Adult Men

For US males aged 20 and older, adult height follows a roughly bell-shaped distribution centered near 5'9" (175 cm), according to CDC/NCHS NHANES body-measure data. Comparing any specific height to this reference population gives a clear, data-backed answer.

When people ask if 5'6" is "tall," they are usually comparing to other adult men. At the 16th percentile, a man at 5'6" (168 cm) is shorter than about 84% of US adult men. This is below average, so the height is not tall by any standard measure.

What Percentile Is 5'6" for a Man?

Using NHANES-based height distributions, 5'6" (168 cm) corresponds to approximately the 16th percentile for US adult males. A percentile tells you what share of the reference population is shorter than you.

For context, the 50th percentile (median) for US men is about 5'9" (175 cm). At the 16th percentile, 5'6" is several inches below that midpoint—which is why it is not considered tall.

What "Above or Below Average" Really Means

"Average" adult male height in the US is about 5'9", but average is not the same as typical range. Most men cluster within a few inches of the mean—roughly 5'6" to 6'0" covers a large share of the population (approximately the 16th to 84th percentiles).

At 5'6", a man is below that cluster. Percentiles clarify what "below average" means numerically: the 16th percentile is precise, while words like "kind of short" are vague. 5'6" is not tall—it is measurably below the US mean.

Social perceptions of "tall" often kick in around the 75th–85th percentile (roughly 5'11"–6'0"). At 5'6", a man is well below that threshold, even though the height is common and unremarkable in daily life.
