Child Height Predictor is a genetic height estimator, calculations run on your device, so amounts and personal figures are never uploaded.

Results update instantly when you change a value; copy them for your records.

Paste or type your content into the input field at the top, or press the sample button to load demo data.
Adjust the options below the input, such as output format, separators, letter case or precision.
Press the main button to run the conversion. Results appear instantly in the output panel without a page reload.
When the result looks right, use the copy button in the corner, or download it as a local file.

Clean up stray spaces and line breaks before pasting for more accurate results.

How accurate is it?+

Within about five centimetres, with pubertal timing adding further variance; treat it as a reference.

Can environment change height?+

Adequate sleep, balanced nutrition and regular activity help realise genetic potential but cannot greatly exceed it.

Is Child Height Predictor free to use?+

Yes. The tool is completely free with no usage limits, and you never need an account or a sign-in.

Is the text I enter uploaded anywhere?+

No. All processing runs locally in your browser, so the input never reaches a server and is never logged or stored.

Does Child Height Predictor work on a phone or tablet?+

Yes. The layout is mobile-first, so inputs and buttons stay comfortable on phones and tablets in both orientations.

Can I copy the result into my own document?+

Yes. A copy button in the output panel puts the result on your clipboard, and you can also download it as a text file.
