In short
Where labels drift. The exceptions are the “strangers” above — e.g. at size 7, Converse Kids, Next Kids, Levi's Kids cut the same number differently. Check those before you trust the label.
Bottom line: for most sizes, a Janie and Jack number is a safe bet elsewhere — measure once, then double-check only the handful of “stranger” brands above.

What shoppers say about the fit
Community consensus
Shopper opinion · not Little & Youth’s measurementThis is what parents report anecdotally — crowd sentiment, not a Little & Youth determination. Our sizing above is computed from Janie and Jack’s own published chart; the notes here come from public parent discussion.
Janie and Jack runs big. Parents consistently find it generous across both boys’ and girls’ lines — a child stays in a size a long time, and slim or petite kids in particular usually size down. Girls’ dresses run especially roomy in length and neckline. It’s upscale, classic children’s wear, so size for the fit you want now rather than for growing room you may not need.
Based on anecdotal discussion from multiple publicly available online sources; your experience may differ.
