UNDERSTAND YOUR GROWTH

When will I stop growing?

Get a rough finishing age, see how much growing time may be left, and check whether your recent growth is slowing down.

You may finish growing around 17 years old, in 2029.

A rough estimate using your age, sex, and average timing. Your actual finishing age may be different.

What your recent growth tells you

Add how much you grew in the past year to see your recent pace here. Add the year before, too, to see whether it’s slowing down.

These are reference heights, not a prediction of your own height.

How is my finishing estimate worked out?

We use one simple estimate: age 17 for boys or 14 years 6 months for girls with average timing. Early bloomer selects age 16 for boys or 14 for girls; late bloomer selects age 18 or 15. These are the earlier end, midpoint, and later end of common finishing ages—not a validated formula for an individual. We subtract your age to estimate time left and use today’s date to estimate the calendar year.

Your measured growth, growth-spurt stage, and family timing add context; they don’t turn this into a medical prediction. We don’t assume you’ll keep growing at last year’s pace. Cleveland Clinic: growth timing for boys ↗ · Nemours KidsHealth: teen growth ↗

If you’re concerned about your growth, a clinician can review measurements over time and, when appropriate, assess bone age. AAP: understanding growth measurements ↗

Where does the chart come from?

We use the US CDC 2000 median (middle) stature-for-age values. It is a population reference, not a target or a forecast for one child. We interpolate this site’s half-year values and stop at age 20. Hover, touch, or use the arrow keys to read the plotted height at each month; that is a reference height, not your predicted height. CDC stature-for-age data ↗

What do the early and late examples change?

The chosen timing changes the finishing-age estimate described above. In the chart, it also moves the pubertal part of the reference earlier or later by up to 0.6 years (about 7 months). These are illustrations, not medically validated early- or late-bloomer charts. Childhood values stay unchanged before the shift begins. Your optional answers do not automatically select an example or change the reference.

The shift fades in from ages 9 to 10 years 6 months for the male reference and 8 to 9 years 6 months for the female reference. All values stay inside ages 2–20. The late example at age 20 reads an earlier point on the reference, so its endpoint is not a prediction of final adult height.

Does family growth timing matter?

Later growth and puberty can run in families. A parent’s late growth spurt is useful background, but does not identify your own growth pattern or guarantee extra growth. Pediatric Endocrine Society: family growth patterns ↗

How should I measure my growth?

Compare heights measured about 12 months apart, without shoes and with the same measuring method. Subtract the older height from the newer one. Enter that difference as the amount grown, not your total height. If the dates are only a few weeks or months apart, leave the yearly growth question blank rather than treating that as a full year.
