The length of time until one stops growing taller mainly depends on age and biological factors. Generally, most people stop growing taller by the end of puberty, which for females is around 16-18 years old and for males is around 18-21 years old. After this period, growth plates in the bones close, and height increase typically ceases. If the question is about an individual still in their growing years, growth can continue for a few more years depending on their current age and stage in puberty. For adults over 21, significant height increase is usually not expected. To provide an accurate estimate on how much longer until growth in height stops, knowing the person's current age and puberty status would be helpful. In summary:
- Females usually stop growing taller by about 16-18 years old
- Males usually stop growing taller by about 18-21 years old
- Height generally does not increase significantly after these ages when growth plates close
If the person is younger than these ages, they may grow taller for a few more years. If older, height growth has likely ended. This average is based on human biological development and growth plate closure timelines noted in medical studies.
