Height is the best guide, then weight; age labels are only a rough guide because babies grow at different rates. Brands differ — check the brand's own chart. EU sizes are the child's height in cm.

Baby clothes are labelled by age, but babies grow at different rates — height is the best guide, then weight. Enter your baby's height, weight or age to get the right size in US/Indian labels (Newborn, 0–3M, 3–6M, 2T…), UK age sizes and EU sizes (which are the child's height in cm).
If your baby is near the top of a size, buy the next one up.
