A free tool that tells you what size your baby wears in each brand, using the brands' own size charts.
Hi, I'm Amzad. I built Baby Size Finder and I keep it up to date. For about ten years my work has been checking and organizing data for businesses, making sure every number in a list matches its source. This site applies that same habit to baby clothes.
Baby sizes don't agree from one brand to the next. A 6M at one store can be a 3–6M or a 9M at another, and each brand's chart lives on its own website. I built Baby Size Finder so parents and gift-givers can enter a baby's weight and height once and see every brand's answer in one place.
Every size comes from the brand's own chart. You can see where each number comes from, and when it was last checked, on How we check sizes.
This site gives clothing sizes only. It is not medical advice, and the growth forecast is not a way to judge whether your baby is growing well. For questions about growth, talk to your pediatrician or health visitor.
Baby Size Finder is not affiliated with, sponsored by or endorsed by any clothing brand. Brand names are used only to say whose size chart a result comes from. No brand pays to be listed or to change a result.
Spotted a size that doesn't match a brand's chart, or want a brand added? Email me at amzad@babysizefinder.com. I check every report and fix confirmed errors within a week.
