Foot Size Chart

This is a foot-size chart for children’s socks. It shows all the various children’s US shoe sizes on the top with the related ages below. However, we are not all made to be the same! Some children may not fit the size relating to their age. This chart generously shows the accompanying foot sizes in inches and centimeters that best fit that size. It also shows where the sock height ends, so you know how high the sock sits on your child’s feet.

Foot size chart

When reading this chart, it is best to take into account the age of your child and their foot measurements. If my child has a foot circumference of 5.5 inches and a foot length of about 6 inches, I would pick a sock size of either 4, 5, or 6. To order the correct pair of socks, it would be best to measure a child’s foot by circumference (all the way around) and the complete foot length. 

Types of Socks

Types of Socks Chart

There are boundless styles of socks. This chart shows each type of sock, what they look like, and where they sit on the foot or ankle. This ranges from socks below and above the ankle, and knee and above the knee. Even socks that may not cover the whole foot or not at all, like toe covers/mute, invisible/no-show, and loose. There are also calf socks that go up to the mid-calf and over the calf just below the knee.

International Kid’s Sock Size

International Kid's Sock Size Chart

This chart shows varying children’s sock sizes that change from country to country. The sizes are accompanied by the respective inches and centimeters that a foot may measure relating to a certain size. So, if my child is size 5.5 in US measurements, their foot will measure 5 inches or 12.7 centimeters. This paves the way to ordering socks internationally as I would be able to order the correct size. Since I usually order a size 5.5 in the US, I would make sure to order a size 4.5 when ordering socks in the UK. 

Some sizes may not translate as easily. That’s why it is best to use the inch or centimeter measurement of your child’s feet length rather than relying on size. 

Feet Size Chart

Shown is a feet size chart. This chart displays the size of a foot with the numbered size that relates. A child’s size starts at 2 and moves up to 13 and a youth’s size starts at 1 and moves up to 7. The chart also shows half sizes to accurately show the specific size of your child’s feet. This helps tremendously with accuracy, as new socks and shoes are needed multiple times per year for children. 

Feet Size Chart

When using this chart, align your child’s heel with the line indicated while they are standing. I would make sure to print it out and have it on the floor to correctly measure the foot size. 


Does a child’s sock size matter?

Socks are important for your child for their overall comfort! They provide cushions between their feet and their shoes & allow them to spend the day feeling cozy. When you are buying socks for your child and they are too small, the socks will form constant holes and fabric tears. You will be continuously buying new socks because of this. If you buy socks that are too big, your child’s shoes will not fit properly either!

If they’re in school or daycare, you are not with them the whole day to know how their shoes and socks are feeling. Finding the right size is vital, you can let them spend their day in comfort rather than having their socks bother them. This will also give you peace of mind by knowing that they are comfortable with what they are wearing. So it is best to measure their feet and get the right size the first time.

What is the best way to measure my child’s foot size? 

Good question! The best way to measure your child’s foot size is to use the feet size chart! 

  1. Print the chart out and lay it flat on the ground. 
  2. Put their heel directly where the heel line indicates. 
  3. With a pen or pencil, create a line where their big toe ends.
  4. Find which size is closest to the line you created.  

How do I measure the circumference of my child’s foot? 

The best way to do this is by using a tape measure for body measurements. Find your child’s arch on their foot and wrap the tape measure around it. Find the closest measurement to the end of the tape measure, and you’ve found your match!

How often should I measure my child’s feet?

Children tend to grow a half size up on average every three months. It’s best to measure your child’s feet every 3 to 4 months. 

How much room should I leave for growth? 

You should leave at least a half-inch of room for your child’s shoes and socks for growth. This will help you get the most use out of them!

Are there width standards for children?

Yes! There are also socks to match these standards as well! Children’s width standards can be narrow, medium, wide, and extra-wide.
