Here’s how Brooks Brothers Kids 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 Brooks Brothers Kids 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.
Pick the size your child wears at Brooks Brothers Kids 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.
Sizes shown use Brooks Brothers Kids’ girls’/unisex chart where the brand splits by gender; boys’ sizes at the same number can run slightly taller.
Where labels drift. The exceptions are the “strangers” above — e.g. at size 12, Noralee, Rylee + Cru, Mayoral cut the same number differently. Check those before you trust the label.
Bottom line: for most sizes, a Brooks Brothers Kids number is a safe bet elsewhere — measure once, then double-check only the handful of “stranger” brands above.

Brooks Brothers Kids-specific things the size number alone won’t tell you — drawn from its own charts.
Public fit reports are sparse; expect a roomy classic fit and go by your child's chest and waist rather than the age on the label.
Boys run 4–20 and girls 4–14 on separate ladders, so size by the matching line.
Which trimmer, roomier, or adaptive cuts Brooks Brothers Kids publishes alongside its standard sizes.
This is what parents report anecdotally — crowd sentiment, not a Little & Youth determination. Our sizing above is computed from Brooks Brothers Kids’ own published chart; the notes here come from public parent discussion.
Brooks Brothers Kids fit reports are split and sparse — expect a classic, fairly full cut, and go by chest and waist measurements. Almost all public discussion comes from small-framed adults who buy the boys’ line, not from parents: a 5’8”, 30-inch-waist man fits boys’ 20/XL and calls both Brooks Brothers and Ralph Lauren ‘big and boxy, including the children’s clothes’, while another buyer says the boys’ cuts are slimmer and cheaper than men’s; a 25-inch-waist woman finds the boys’ size-18 Advantage chinos slightly big but the closest fit she has found; several men wear boys’ 16 and 18 dress shirts and blazers and rate them as well made as the mainline. The consistent thread is quality and value rather than a fit direction. This block rests on about 15 comments across Reddit and DISboards, so treat it as provisional and use the brand’s published chest, waist and inseam chart.

Find my child’s size →Shop Brooks Brothers Kids ↗There is no clear consensus. The few shoppers who describe the cut split between 'big and boxy' (a 5'8" adult fits boys' 20/XL) and 'slimmer than men's'; a 25-inch-waist adult found boys' 18 chinos slightly big. With so little parent feedback, the safest approach is to measure chest, waist and inseam against the brand's chart and to plan on a tailor for suits and blazers.
Yes — this is the most common reason the line comes up online. Men around 5'8" and 160 lb report fitting boys' 20/XL, several buy boys' 16 and 18 non-iron dress shirts, and a petite 25-inch-waist woman wears the boys' 18 Advantage chinos. Buyers say to try on in store first and avoid assuming the outlet line is the same product.
Shoppers say yes for the mainline boys' suits, blazers and shirts — 'as good quality as mainline and significantly cheaper' is the recurring verdict — with the caveat that outlet (346) merchandise is a different, lower-grade line.
Brooks Brothers Kids publishes height, weight, chest, waist, hip, sleeve in its size chart. Height is the primary driver, and the chest/waist figures let you confirm body fit for a child between sizes.
From the bigger sizes up, Brooks Brothers Kids publishes separate girls’ and boys’ charts, so the same number can differ by gender. The figures on this page use Brooks Brothers Kids’ girls’/unisex chart.
Brooks Brothers Kids is sold on its own site and on Amazon, so you can pick the marketplace you prefer.
