Here is a comprehensive reference for normal weight and height in children aged 1–10 years, based on CDC growth charts (NCHS 2000) as published in the Textbook of Family Medicine, 9th Edition.
Normal Height & Weight: Ages 1–10 Years
The values below represent the 50th percentile (median) for each sex, drawn from CDC growth charts. The normal range spans the 5th to 95th percentile — any child tracking consistently along their own percentile curve is considered growing normally, regardless of the absolute value.
📊 Boys — 50th Percentile (Approximate Median)
| Age | Height (cm) | Height (in) | Weight (kg) | Weight (lb) |
|---|---|---|---|---|
| 1 yr | ~75–76 | ~29.5–30 | ~10.0 | ~22 |
| 2 yr | ~87–88 | ~34–34.5 | ~12.5 | ~27.5 |
| 3 yr | ~95–96 | ~37.5 | ~14.5 | ~32 |
| 4 yr | ~103 | ~40.5 | ~16.5 | ~36 |
| 5 yr | ~110 | ~43 | ~18.5 | ~41 |
| 6 yr | ~116 | ~45.5 | ~21 | ~46 |
| 7 yr | ~122 | ~48 | ~23 | ~51 |
| 8 yr | ~128 | ~50.5 | ~25.5 | ~56 |
| 9 yr | ~133 | ~52.5 | ~28.5 | ~63 |
| 10 yr | ~138 | ~54.5 | ~32 | ~70 |
📊 Girls — 50th Percentile (Approximate Median)
| Age | Height (cm) | Height (in) | Weight (kg) | Weight (lb) |
|---|---|---|---|---|
| 1 yr | ~74–75 | ~29–29.5 | ~9.5 | ~21 |
| 2 yr | ~86–87 | ~34 | ~12 | ~26.5 |
| 3 yr | ~94–95 | ~37 | ~14 | ~31 |
| 4 yr | ~102 | ~40 | ~16 | ~35 |
| 5 yr | ~109 | ~43 | ~18 | ~40 |
| 6 yr | ~115 | ~45 | ~20.5 | ~45 |
| 7 yr | ~121 | ~47.5 | ~23 | ~51 |
| 8 yr | ~127 | ~50 | ~25.5 | ~56 |
| 9 yr | ~133 | ~52.5 | ~29 | ~64 |
| 10 yr | ~138 | ~54.5 | ~33 | ~73 |

Key Clinical Points
- Normal growth velocity: Height gain decreases from ~25 cm/year in the first year of life to ~5–6 cm/year by age 6–7 years.
- Normal range: 5th to 95th percentile is considered normal. Values outside this range (>95th or <5th) warrant evaluation but may still be normal.
- Trend matters more than a single measurement: A child tracking consistently along their own curve — even if below the 5th or above the 95th percentile — is likely growing normally for that individual.
- BMI classification in children (age 2+):
- <5th percentile = underweight
- 5th–84th percentile = healthy weight
- 85th–94th percentile = overweight
- ≥95th percentile = obese
- Recumbent length is used until age 2 (child lying down); standing height is used from age 2 onward.
