Here’s how Lacoste Kids fits your child compared to other brands you might be considering, so you know before it’s in your cart.
Find your child’s Lacoste Kids size on the left. Twins wear the same number the same way — your size carries straight over. Strangers use the same number but cut it shorter or longer, so don’t trust the label alone.

Sizes shown use Lacoste Kids’ girls’/unisex chart where the brand splits by gender; boys’ sizes at the same number can run slightly taller.
Where the number just works. At 1, Lacoste Kids lines up with every brand we track — the size carries straight over.
Where labels drift. The exceptions are the “strangers” above — e.g. at size 8, Garnet Hill, Old Navy, Converse Kids cut the same number differently. Check those before you trust the label.
Bottom line: for most sizes, a Lacoste Kids number is a safe bet elsewhere — measure once, then double-check only the handful of “stranger” brands above.

Which trimmer, roomier, or adaptive cuts Lacoste 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 Lacoste Kids’ own published chart; the notes here come from public parent discussion.
Lacoste kids runs small and shrinks — size up, and air-dry. The signature pique polos are cut slim and narrow, and reviewers report they shrink noticeably in the wash, so parents routinely go up a size or two (sometimes more) and skip the dryer. It uses French sizing by age in years (2A, 4A…), which reads smaller than US sizes, so lean on your child’s measurements over the age label.
Based on anecdotal discussion from multiple publicly available online sources; your experience may differ.
Enter your child’s measurements once. We’ll show their Lacoste Kids size and their size at 100+ other brands, each from that brand’s own chart.
Find my child’s size →Shop Lacoste Kids ↗On Amazon ↗Most parents go up one or two sizes — some more for a roomy fit — because the polos run slim and shrink. Air-dry to limit the shrinking, and size to your child’s chest measurement rather than the age on the label.
Lacoste is French and labels by age in years ('A' = ans). It reads smaller than US sizing, so a 6A isn’t a US size 6 — convert from your child’s real height, and remember it runs small on top of that.
Lacoste Kids publishes height, chest, waist, hip 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, Lacoste Kids publishes separate girls’ and boys’ charts, so the same number can differ by gender. The figures on this page use Lacoste Kids’ girls’/unisex chart.
Lacoste Kids is sold on its own site and on Amazon, so you can pick the marketplace you prefer.
