Çocuklar ve Gençler İçin BMI Hesaplayıcı (2–20 Yaş)
2–20 yaş arası çocuklar için ücretsiz pediatrik BMI hesaplayıcı. Çocuğunuzun BMI'sini, kilo durumunu ve büyüme eğrisi persentil tahminini öğrenin.
CDC büyüme eğrisi persentilleri ile çocuklar için yaşa göre BMI hesaplayın.
BMI for children is calculated the same as adults but interpreted using age- and sex-specific growth chart percentiles.
Formula: BMI = weight (kg) ÷ height (m)²
CDC Weight Status Categories
| Category | Percentile |
|---|---|
| Underweight | Below 5th |
| Healthy weight | 5th–84th |
| Overweight | 85th–94th |
| Obese | 95th+ |
How to Use
- Select sex (male/female)

Examples
Example 1 — 10-year-old boy: 35 kg, 140 cm → BMI = 35 ÷ 1.96 = 17.9 (Healthy weight — below 85th percentile of 18.9)
Example 2 — 12-year-old girl: 50 kg, 152 cm → BMI = 50 ÷ 2.31 = 21.6 (Overweight — between 85th percentile 21.3 and 95th percentile 23.4)
Example 3 — 15-year-old boy: 75 kg, 170 cm → BMI = 75 ÷ 2.89 = 26.0 (Obese — at or above 95th percentile of 26.1)
FAQ
Why not use adult BMI categories for children? Body fat changes dramatically through childhood and adolescence and differs between sexes. The CDC growth charts account for these changes using age- and sex-specific percentiles.
What if my child is classified as overweight? This is a screening result, not a diagnosis. Consult a paediatrician for full assessment including growth trend, physical exam, and family history.
Can a child outgrow a high BMI? Yes. Height increases can normalise BMI during growth phases. Growth trends over time are more informative than a single reading.
How accurate are the percentile estimates? This tool uses simplified lookup tables with approximate 5th, 85th, and 95th percentile cutoffs. For clinical-grade results, use the CDC’s official BMI Percentile Calculator.
Is BMI the best measure for children? No. BMI is a population screening tool. More accurate body composition methods (DXA, skinfolds, BIA) exist but are not used in routine care for healthy children.
