Understanding the Results

The percentile result indicates where your baby's measurement falls compared to other babies of the same age. Here's what the different percentiles mean:

Below 3rd percentile: Your baby is smaller than most babies of the same age. This may warrant medical attention.
3rd to 10th percentile: Your baby is smaller than average but within the normal range.
10th to 90th percentile: Your baby is growing at a typical rate.
90th to 97th percentile: Your baby is larger than average but within the normal range.
Above 97th percentile: Your baby is larger than most babies of the same age. This may also warrant medical attention.

Percentile = (Number of babies with measurements below yours / Total number of babies in the study) × 100
