Kids' Clothing Fit Chart: Which Children's Clothing Brands Run Big, Which Run Small, and How to Find Your Kid's Best Fit
Almost every kids brand in existence has been shipped out in one of our nearly-new kids clothing boxes. So, we can tell you firsthand that a girls’ 3T shirt from Carter’s can be a totally different fit from a 3T girls’ shirt from Old Navy. A boys’ six-month onesie from Gerber has a good chance of being way smaller than a six-month onesie from OshKosh B’Gosh. When it comes to children’s clothing, fit can vary wildly across sizes and brands. We sort through thousands of kids clothing items each month and see all variety of brands, so when it comes to how different kids clothes fit, we like to think we’re experts and authorities!
Finding Clothes that Fit Your Kid
Just like when shopping for your own clothes, you have to keep your kiddo’s shape in mind. Some brands are known to be cut more tall and slim while others have the short and stockier market cornered. And to make matters more complicated, as a lot of us moms know, kids often alternate, growing tall, then wide…. then tall, then wide again. For example, Carter’s is one brand that is consistently designed for long, narrow babies, while Gymboree (which just went out of business in 2019) always had some room for the roly poly phases.
Here are four tips we swear by when it comes to finding the best-fitting kids’ clothes for your littles:
1. Check the size chart: Children’s clothes in the U.S. are conveniently sized by age, and it’s tempting to want to buy that way. But it’s always good to consult a brand’s size chart before buying anything new. Compare your kiddo’s measurements against the brand’s height/weight guidelines for the best fit.
2. Think of baby sizes as “up to”: When you’re looking at clothing that sizes by month, it’s best to see it as topping out at that month. For example, a “3 months” onesie will fit up to a three-month-old baby, and a “9 months” tee may fit your six or seven-month-old.
3. Know the difference between 24 months and 2T: This is a case of a baby versus a toddler. Is your babe more chunky baby (complete with a diaper), or active toddler who might already be in undies? The 24-month-old clothes are designed for rounder baby shapes, while 2T will be more slim and streamlined.
4. Some styles are more forgiving: Dresses are easier to fit since they tend to be less form-fitting. Jeans and pants can be more challenging. Elastic waists and adjustable-waist pants are definitely a mom’s best friend, especially if you have a tall and skinny kid! Pay attention to the style when you’re shopping; some brands offer slim and husky styles in their bigger kid sizes.
