Bands are percentiles among adults of the same sex: shortest 3% "very short", tallest 20% "tall", tallest 3% "very tall" — the same scale as every "Is it tall?" page on this site. Not a medical definition.
In Iran, men under 166.3 cm (5′5″) are short (shortest 20%) and under 158.5 cm (5′2″) very short (shortest 3%). For women the limits are 152.2 cm (5′0″) and 144.9 cm (4′9″). Short or tall is just a statistical position.
