Which one do you need?
| Your question | Tool |
|---|---|
| I have a height in cm and need feet and inches, or the other way | Height converter |
| How tall will my child be as an adult? | Height predictor |

| Is my child (2 to 20) tall or short for their age? | Height and weight percentile |
| Where is my baby on the growth chart? | Baby height percentile |
Garbage in, garbage out
Every one of these tools is only as good as the height you type. A shoe, a slouch or a carpet is worth a centimetre or two, and on a child's growth chart that is several percentile points. Before trusting any result, read how to measure height accurately at home: it takes two minutes with a wall, a hardback book and a pencil.
No wall handy, or measuring something that is not a person? The Measure Height app for iPhone estimates height, width and depth from one photo and tells you how confident it is.
