In short
Where the number just works. At Up to 5lb, Preemie, 36M, 6 / 6X, 6X, OshKosh B'gosh 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 5, Il Gufo, Converse Kids, Levi's Kids cut the same number differently. Check those before you trust the label.
Bottom line: for most sizes, a OshKosh B'gosh number is a safe bet elsewhere — measure once, then double-check only the handful of “stranger” brands above.

Fit & the transitions that trip parents up
OshKosh B'gosh-specific things the size number alone won’t tell you — drawn from its own charts.
Shares Carter’s size chart
OshKosh and Carter’s are the same parent company and use one chart, so a size that fits in Carter’s tops and everyday basics fits here too.
Basics true, overalls and denim run trim
Plain basics you can buy straight. The structured pieces — denim and especially the signature overalls — are cut slimmer, and the sleepwear runs snug, so size up on those (and on overalls for a toddler still in diapers).
Slim, Plus and Husky cuts (sizes 4–14)
Because it shares Carter’s chart, OshKosh offers the same Slim, Plus and Husky cuts in sizes 4–14 — each the same height as the regular size, adjusted through the waist and seat.

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 OshKosh B'gosh’s own published chart; the notes here come from public parent discussion.
OshKosh runs true to size on basics, and slimmer than Carter’s on its structured pieces. It shares Carter’s size chart (same parent company), so tops and everyday basics fit interchangeably — but the denim, and especially the signature overalls, are cut trimmer, and the sleepwear runs snug. Size up on the structured pieces (and on overalls for a toddler still in diapers); the plain basics you can buy straight.
Based on anecdotal discussion from multiple publicly available online sources; your experience may differ.
Should you buy OshKosh B'gosh?
Consider it if…
- You want durable playwear — OshKosh is built around sturdy denim, overalls and active basics that survive hard play.
- You want a classic, timeless look — its denim-and-overalls aesthetic doesn’t chase trends.
- You want value pricing — it’s the affordable end, with frequent sales like its sibling Carter’s.
Think twice if…
- You want dressy or occasion pieces — it’s rugged everyday playwear, not formalwear.
- You want range and variety — it’s focused on denim, overalls and playwear, narrower than Carter’s prints and coordinated sets.
- You want premium construction — it’s value-tier: durable for the price, not heirloom.
Skip the cross-referencing — let Little & Youth do it.

Is OshKosh the same sizing as Carter’s?
Yes — OshKosh and Carter’s are owned by the same company and share one size chart, so the numbers carry straight over. The difference is cut: OshKosh’s denim and overalls run trimmer than Carter’s softer basics.
Why do OshKosh overalls and denim fit so slim?
They’re cut close for active play without bulk — great over a onesie, snug over a diaper. For a toddler still in diapers, sizing up one is the common fix; the plain basics you can buy at your child’s regular size.
What measurements do I need to size OshKosh B'gosh accurately?
OshKosh B'gosh publishes height, weight, chest, waist 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 OshKosh B'gosh boys’ and girls’ sizes fit the same?
From the bigger sizes up, OshKosh B'gosh publishes separate girls’ and boys’ charts, so the same number can differ by gender. The figures on this page use OshKosh B'gosh’s girls’/unisex chart.
How do I choose between OshKosh B'gosh’s regular, Slim, Plus and Husky cuts?
Each of these is the same numbered size as the regular cut — same length, adjusted through the waist and seat (Slim trimmer, Plus and Husky roomier). So size to your child’s usual OshKosh B'gosh number from the chart above, then pick the cut by build: a smaller waist for Slim, a fuller waist and seat for the roomier cuts. You don’t need a separate measurement to choose.
How do OshKosh B'gosh’s shoe and sock sizes work?
OshKosh B'gosh carries kids’ shoes alongside its clothing. Kids’ shoe sizes go by foot length rather than age, and the same size number isn’t cut the same from brand to brand — so measure your child’s foot and check it against the chart. OshKosh B'gosh’s socks are sized by shoe size, not age — buy for your child’s current shoe size, and if they fall between two ranges choose the smaller so the sock stays up. See how every kids’ shoe brand runs and how wide each is cut on our kids’ shoe sizing guide.
