Walk through age, condition, and population to pick the right reference.
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 uses the Khamis-Roche regression with a child's age, sex, current height and weight, and both parents' heights. 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 view, who want a combined growth summary, or who want an informational adult-height estimate before discussing growth questions with a clinician.
When to use these calculators
Use the Growth Dashboard for a routine growth summary. Use the Height Predictor for an informational adult-height estimate, not treatment planning. 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?
- In the Khamis-Roche study sample, empirical 90% absolute-error bounds averaged across ages were about ±5.34 cm for boys and ±4.25 cm for girls. These are not standard errors or guaranteed ranges for an individual child, and the calculator should not guide treatment decisions.
- 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.
