Nautica
Here’s how Nautica fits your child compared to other brands you might be considering, so you know before it’s in your cart.
What size is (and isn’t) like Nautica at other brands?
Find your child’s Nautica 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 Nautica’s girls’/unisex chart where the brand splits by gender; boys’ sizes at the same number can run slightly taller.
In short
Where labels drift. The exceptions are the “strangers” above — e.g. at size S, Reebok Kids, Vineyard Vines Kids, Nike Kids cut the same number differently. Check those before you trust the label.
Bottom line: for most sizes, a Nautica number is a safe bet elsewhere — measure once, then double-check only the handful of “stranger” brands above.

Should you buy Nautica?
Consider it if…
- Its sizing spans a wide range, so one brand can cover several years.
- You care about body fit, not just height — Nautica publishes chest/waist so you can confirm the cut.
- It’s easy to buy — available on Amazon as well as the brand’s own site.
Think twice if…
- Always confirm on the retailer’s live chart before buying — brands revise sizing over time.

What measurements do I need to size Nautica accurately?
Nautica publishes height, weight, 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.
Do Nautica boys’ and girls’ sizes fit the same?
From the bigger sizes up, Nautica publishes separate girls’ and boys’ charts, so the same number can differ by gender. The figures on this page use Nautica’s girls’/unisex chart.
Where do I buy Nautica?
Nautica is sold on its own site and on Amazon, so you can pick the marketplace you prefer.
