The average height for a woman in the U.S. is about 5 feet 4 inches (roughly 163 cm), though some sources report 5 feet 3.5 inches depending on the dataset and year.

Quick Scoop

  • U.S. average: about 5'4" for adult women.
  • Another recent estimate: 5'3.5" in the U.S..
  • Global average: varies a lot by country; there isn’t one single worldwide number.
  • Typical range: a few inches above or below the average is usually normal.

What affects height

  • Genetics is the biggest factor.
  • Nutrition and childhood health also matter.
  • Height averages differ by country and region.
A simple way to think about it: if someone says the “average woman is 5'4",” that’s a rough population benchmark, not a rule for any individual.

Bottom line

If you just want the number, about 5 feet 4 inches is the most common U.S. average to use.
