Is 4′9″ tall? How it compares with US adults
For a man, 4′9″ is very short (below the 5th percentile). A normal-curve estimate puts it rarer than 1 in 10,000. For a woman it is very short (below the 5th percentile). A normal-curve estimate puts it at roughly 1 in 120.
| Group | Where 4′9″ falls | Median height | Difference |
|---|---|---|---|
| Men 20 and over | below the 5th percentile | 175.4 cm | −30.6 cm (−12.1 in) |
| Women 20 and over | below the 5th percentile | 161.3 cm | −16.5 cm (−6.5 in) |
| Men 20–29 | below the 5th percentile | 176.0 cm | −31.2 cm (−12.3 in) |
| Women 20–29 | below the 5th percentile | 162.8 cm | −18.0 cm (−7.1 in) |
