Here’s how Burt's Bees Baby fits your child compared to other brands you might be considering, so you know before it’s in your cart.
Enter your child’s measurements once — we’ll size them in Burt's Bees Baby and at 100+ other brands, each from that brand’s own published chart. Height and weight are required; add chest, waist, hips and inseam to sharpen the fit.
Burt's Bees Baby publishes one unisex chart, so that is what we size against.
Pick the size your child wears at Burt's Bees Baby to see which brands have the same label and measurements (twins) and which run shorter or longer (strangers) — based on each brand’s own chart.
Where labels drift. The exceptions are the “strangers” above — e.g. at size 2T, Garanimals, Macy's Epic Threads, Macy's First Impressions cut the same number differently. Check those before you trust the label.
Bottom line: for most sizes, a Burt's Bees Baby number is a safe bet elsewhere — measure once, then double-check only the handful of “stranger” brands above.
