Height Prediction

If You're 5'10" at 13, 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)

6'6"

Range: 6'4" – 6'8"

5'10" at 13 is well above average for boys at 13 (roughly 90th–95th percentile).

Girls (Female)

6'1"

Range: 5'11" – 6'3"

5'10" at 13 is well above average for girls at 13 (roughly 90th–95th 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 13?

Boys

Boys at age 13 still have meaningful growth remaining — typically 6–10 more inches.

Girls

Girls at age 13 are approaching their adult height — typically 1–4 inches of growth remaining.

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 13, we estimate how many inches of growth remain for a typical person of that height and age.

For someone who is 5'10" at age 13: we calculate your expected remaining growth (boys: ~6–10 inches; girls: ~1–5 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 5'10" at 13 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 13 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 13.

Is 5'10" above average for a 13-year-old?

CDC median for 13-year-olds is about 5'2" for boys and 5'1" for girls. At 13, most girls are near or past their peak growth spurt, while many boys are still accelerating. 5'10" relative to 5'1"–5'2" tells you roughly where you are compared to your peers.

How much more do boys grow after 13?

Boys who are 13 and still early in puberty may have 6–9 more inches of growth ahead. Boys who are 13 and further along in puberty may have only 3–5 more inches. On average, CDC data shows boys at 13 grow about 8 more inches before reaching adult height. The growth spurt typically peaks around age 13–14 for boys.

Is it too late for girls to grow significantly at 13?

Not necessarily, but girls at 13 are usually past their peak growth year. CDC data suggests girls at 13 have an average of 2.5–3 inches of growth remaining. Girls who are late bloomers (puberty started later than average) may have more. By 15, most girls are within 1 inch of their final height.
