Calculate Percentile

Companion tools that complement the per-chart percentile calculators. The Growth Dashboard combines weight, length/height, head, and BMI percentiles into a single all-in-one view (the WHO 0-24 baseline). The Height Predictor estimates adult height from current height and parental heights using the mid-parental method. The 'Which Chart?' tool guides users to the appropriate growth chart based on age, condition, and clinical context.

These tools are entry points for users who don't know which specific chart to look at, who want a single combined assessment, or who want to predict the adult height for planning purposes (e.g., orthodontia, scoliosis surgery timing).

When to use these calculators

Use the Growth Dashboard for routine well-child summary screening. Use the Height Predictor for adult-height planning conversations. Use 'Which Chart?' when you're unsure which reference is appropriate (preterm? Down syndrome? Chinese population? WHO vs CDC?).

Frequently Asked Questions

How accurate is the Height Predictor?
The mid-parental method has typical error of ±2 inches (5 cm) at one standard deviation, which is fine for clinical conversations but not for high-stakes timing decisions. More accurate methods (Bayley-Pinneau, Roche-Wainer-Thissen, Greulich-Pyle) require bone-age X-rays.
What does the Growth Dashboard use as its reference?
The Growth Dashboard uses WHO 0-24 month standards by default. For older children or non-WHO references (CDC, Olsen, Zemel, Chinese), use the per-chart calculators on this site.
Which chart should I use for my child?
The 'Which Chart?' tool walks through age, condition (term/preterm), syndrome status (none/Down), and population (international/U.S./Chinese) to recommend the appropriate chart from the site's catalog.
