Finding perfectly-fitting clothes for your kids can get seriously challenging, especially when you don’t know your way around the complicated world of children’s clothing size conversion charts. To help struggling parents with child sizes who may find themselves in over their heads, this page contains a comprehensive kids size chart overview. Child sizes have never been that easy.
At a Glance
- There is no universal child sizing standard that every country and all clothing brands are required to follow. Different countries have their own set of standards for kids size charts, and most brands take liberties in how they follow them. Therefore, it is always best to refer to the size guide of a particular clothing brand you patronize.
- In finding the right fit for your child, take note of his age, gender, height, and weight. But if you want to be more accurate in your selection of clothing size for your kid, you also need to take measurements of his (1) chest, (2) waist, (3) hip, and (4) inseam.
- The United States, like the United Kingdom and Australia, observes kids clothing sizes that are based on age. However, as for the rest of Europe, sizing for children’s clothes are based on height, and it is measured in centimeters.
- To determine your child’s shoe size, you need to trace his foot on paper. Start from the highest point of his toe and all the way to the tip of his heel. Take note of the foot length and width in inches and centimeters. Then, you can refer to the shoe size chart of the specific brand you will buy from.

U.S. sizing for kids, like in the United Kingdom and Australia, are based on age. European kids clothing sizes, which applies outside of the U.K., differ because manufacturers in this continent base their sizing on height. Moreover, a kid’s height is measured not in inches, but in centimeters. And so, you need to refer to conversion charts if you want to get the right clothing fit for your child. Make sure you find one that contains specific body measurements so that all you need to do is to convert American inches to European centimeters. Here you may find more information about Asian Clothing Sizes for Kids.

Children’s Shoe Sizes
To determine your child’s shoe size, you need to trace his foot on paper. Start from the highest point of his toe and all the way to the tip of his heel. Aside from that, don’t forget to write down the measurements both in inches and centimeters. Once you got those details down, all you need to do is to refer to the kids’ shoe size chart or baby shoe size chart of the brand you plan on buying from in order to figure out your child’s appropriate shoe size.

Tip: Don’t be surprised if your child’s feet grow fast. You must keep in mind that the next time you buy another pair for him, leave enough room for his growth of 0.5-0.7 inches.
Child Sizes Are Really Tricky
That’s the frustrating thing about classifying clothing sizes; there is no universal standard that every country and every clothing brand must follow. Different countries have set their own standards. And in some countries, like the United States, following the standard isn’t even a strict rule but merely a recommendation. Therefore, even if you’re very familiar with international clothing sizes, you’re still not sure if you’re getting the right fit. Clothing brands themselves have varying measurements for the different sizes they offer. Your child could be a size 10 in one brand but a size 11 in another.
And so, keep in mind that the conversion chart provided below, like many other generic size charts online, are just estimates. You should use it only as a guide but don’t expect that it will be 100% accurate all the time.
How to Take Your Child’s Measurements
The best weapon you have in your mission to find perfectly-fitting clothes for your kid is a tape measure. Indeed, you need to know your child’s age, height, and weight because they are usually what clothing sizes are based on. However, if you want to be more accurate when shopping clothes, especially online, then you need to do the legwork by measuring several areas of your child’s body and then look up the size in the respective kids size chart below.
When taking your kid’s measurements, make sure you do it over his bare skin or while he’s wearing tight-fitting clothes. Basically, you need to record the measurements of the following body parts:
- Chest. Wrap the tape measure around the fullest part of your child’s chest.
- Waist. Wrap the tape measure around your kid’s natural waist. This usually close to where the bellybutton is.
- Hip. Measure the fullest part of the hips. Make sure your kid is standing still with his feet together.
- Inseam. Measure from the crotch area all the way down to your child’s ankle.
After taking note of your child’s exact measurements, you can now refer to a size chart to check for the appropriate clothing size. Again, keep in mind that generic kids size size charts may be reliable guides, but it is still best that you refer to the published size charts of the clothing brand you are buying from.
