Height Prediction

If You're 4'10" at 10, How Tall Will You Be?

Estimated adult height based on CDC growth trajectory data. Results shown for both sexes — scroll down for the full breakdown.

Boys (Male)

6'1"

Range: 5'11" – 6'3"

4'10" at 10 is above average for boys at 10 (roughly 75th–85th percentile).

Girls (Female)

5'8"

Range: 5'6" – 5'10"

4'10" at 10 is above average for girls at 10 (roughly 75th–85th percentile).

These estimates use CDC 50th-percentile growth trajectory data. Individual results vary based on genetics, puberty timing, and nutrition. ±2 inches for ~80% of individuals.

Growth remaining

How much more will you grow at 10?

Boys

Boys at age 10 still have substantial growing ahead — typically 13–17 more inches before reaching adult height.

Girls

Girls at age 10 still have meaningful growth remaining — typically 8–11 more inches.

About this estimate

How we calculated this.

This prediction is based on CDC National Health and Nutrition Examination Survey (NHANES) growth chart data — specifically the 50th-percentile height trajectory for boys and girls from ages 10 to 20. By comparing the median adult height (age 20) to the median height at age 10, we estimate how many inches of growth remain for a typical person of that height and age.

For someone who is 4'10" at age 10: we calculate your expected remaining growth (boys: ~13–17 inches; girls: ~8–12 inches), add it to your current height, and display the result. A ±2 inch confidence range covers approximately 80% of real-world outcomes.

Important limitation: this estimate does not account for your parents' heights, which influence about 60–80% of adult height variation. A child of two tall parents who is 4'10" at 10 is likely to end up taller than predicted here; a child of shorter parents may end up shorter. For a more accurate prediction, use our full Khamis-Roche calculator — it incorporates parent heights and reduces the error to ±1.7–2.2 inches.

Puberty timing also matters significantly. Early developers at age 10 have already grown through part of their spurt; late developers still have that growth ahead. Our Growth Plate Status quiz can help estimate where you are in your development timeline.

Frequently asked

Questions about height at 10.

Is 4'10" tall or short for a 10-year-old?

It depends on sex. The CDC 50th percentile for 10-year-old boys is about 4'6" and for girls is also about 4'6". Heights vary widely at age 10 because kids enter puberty at different times. Being taller or shorter than average at 10 does not predict final adult height very accurately.

How much do kids grow between ages 10 and 18?

Boys typically grow 13–17 inches between ages 10 and 18, with most of that growth during the pubertal growth spurt (ages 12–15). Girls grow 9–12 inches, with their spurt usually occurring earlier (ages 10–13). These are medians — early or late puberty shifts the timing significantly.

Can you predict final height at age 10?

A rough estimate is possible, but accuracy is lower at younger ages because the timing of puberty (which accounts for 2–4 years of major growth) is still unknown. The Khamis-Roche method improves accuracy by including the child's current height and parents' heights. Even so, ±2–3 inches is the realistic confidence range at age 10.
