Are these size calculations individual or approximate?

Every forecast is individualized based on the data points you provide. This ensures size recommendations are tailored specifically to your baby's growth profile.

Why do you need my baby's birth date?

Your baby's age is essential for calculating growth rates from WHO standards. The predictor uses age to apply the correct growth trajectory when forecasting future sizes.

My baby is around the 40th percentile, but the form only offers 25th or 50th. Which should I pick?

We recommend rounding up to the next percentile (50th) to avoid a too-snug fit. For maximum precision, switch to "Measured Height" mode and enter your baby's actual measurements.

When I'm asked for a percentile, is it compared to all babies of the same age, or specific to gender?

Percentiles are gender-specific: they compare your baby's measurements only to other infants of the same gender and age group.

How accurate are these predictions?

Forecasts become more consistent as your baby grows. In the first 3-6 months, percentiles can fluctuate, so we recommend using recent height measurements for that age range. After six months, percentile-based projections tend to be very reliable.

What information is shared when I generate a “Share My Sizes” link?

The link includes only your baby's name, date of birth, gender, and the 12-month size forecast. No other personal data is disclosed.

I can't tell which sizing system a garment uses when I'm shopping. What should I do?

Height-based sizing is the most reliable indicator of fit. EU sizes map directly to your baby's length in centimeters, so they typically deliver the truest fit when you don't know the brand's sizing chart.
