Kids Socks Size Chart by age: What are sock sizes for boys & girls
Socks for children are typically labeled with either a shoe size, an alpha size (S-M-L), or a specific kids’ sock size (a number between 0 and 12). See the Kids Socks size chart below to determine your children’s sock size (both alpha and specific sock size in US, EU or UK sizes) based on shoe size or age.
When you buy socks for your child that are too small, the socks will develop frequent holes and fabric tears. If you buy socks that are too big, your child’s shoes will not fit properly!

Why it is essential to know the right size before you buy Kid’s Socks
Buying socks for a newborn can be a little tricky. Keeping in mind that babies continue to grow, it is best to buy socks that are not too small or too large.
The best way to get it right is using a Kids Socks Size chart. When it comes to children’s sock sizes, there is no established norm. They may occasionally be offered according to size, age, or shoe size (e.g. toddler).
The sock size chart allows one to enter the child’s age or determine the size of the child’s socks based on their shoe size. We used the following charts for the US, EU, and UK sock sizes.

One of the biggest advantages of knowing the right size before you buy kids socks is that you will be able to ensure that your kid is comfortable. Children’s feet can be a little small, and too big socks can make them feel uncomfortable.
Too tiny socks, on the other hand, can be too tight and might cause health problems as they can interfere with blood flow around the feet. Likewise, a child will not voice that concern if their socks are too big or too small.
This is why you must always aspire to get the size right.
Kids Socks Size Chart
To help you pick the right size, a Kids Socks Size Chart is necessary as socks come in many sizes. A newborn will need a baby sock, a few sizes larger.
A toddler or youth sock is designed to fit a child with a shoe size of two to six. A child of eight years and up should wear a youth or medium sock.
With all these options to think about, you will save a lot of time and money by using a Kid’s Socks Size.
All sports brands offer kid’s socks, like adidas socks, Nike socks, Puma Socks, …

How to choose the right Kid’s Socks Size
Choosing the right kid’s socks size is a task you must take seriously. Kids’ feet are smaller than adults, and their socks should fit properly.
The general rule is that you must choose the smallest size for infants. For pre-teens, choose the largest size.
The best sock for a baby is one that fits snugly around the heel and is comfortable. Luckily, most brands have sizing charts on their websites to guide you.
You can also try your child’s socks on before buying them. However, remember that kids’ socks are made of thin material and will stretch with use.
Therefore, sizing should be considered to ensure the socks will fit properly. It is important to note that kids’ feet do not always express their discomfort, so sizing up can help to ensure a comfortable fit.
The right sock should not only be comfortable but should also be durable.
The best Kid’s Socks Size for your children
When looking for the best kid’s Socks Size for your child, the first thing to consider is your child’s shoe size. A shoe of the same size can fit a child in a child’s socks of different age.
For example, if a kid is a two-year-old, they should wear a pair of toddler socks. Kids four and up should be in children’s sizes four and up.
A high-growth child can go to the next level by selecting a size eight or higher. Toddlers are typically in toddler socks ranging from sizes three to seven.
They can easily move into a child’s size eight or larger as they grow older. Once they reach the age of four, the child can wear kids’ sizes eight and up. Fortunately, most kids grow into the same shoe size by the time they’re ten.

Kids’ socks are generally categorized according to shoe size and age. For newborns, the best sock size fits the shoe well.
There’s the junior size for older children, which is meant for children in shoes with a size five and up. And for teenagers, a size eight sock is ideal.
How to measure, how to find your Kid’s Socks Size
Knowing how to measure your child’s feet for the correct sock size is important for comfort and fit.. If it’s too small, the heel will appear under the foot.
The material should not bunch up when your child slips their shoes on. Loose socks can feel uncomfortable inside the shoe. A pair that sits properly should have no toe seam.
How to determine your child’s sock size
The best way to determine child sock size is to measure the length of the foot. The length of the foot will determine the sock size. Regardless of the brand, it’s important to know the correct length.
Measure your kid’s feet in 10 simple steps
- Measure your kid’s feet in the afternoon.
- Make them Stand When Measuring, but with smaller children this is not needed
- Be precise
- Measure both feet
- Stand on a piece of paper
- Start drawing
- Measure the length of your kid’s feet
- Determine your kids socks size in the conversion charts
You should choose a size smaller than the child’s normal shoe size for newborns. The same holds for babies. Sometimes, baby socks can double as holiday decorations or change purses.
There are three general sizes: infant, toddler, and kids. A toddler sock fits a newborn to a year old. For children between the ages of five and ten, you’ll need a child sock between the infant and toddler sizes.
How often should I take my kid’s foot measurements?
Every three months, kids typically go up a half size. Your child’s feet should ideally be measured every three to four months. Related: Kids Shoe Size by Age: your child’s shoe size with easy size-charts
