Can you guess the average shoe size by age chart? Well, you can never tell the exact shoe size, especially when you shop online for children. The shoe size of children is uncertain due to their growing age. When you shop online, you are at risk of choosing the wrong size.

However, you need to get your shoe exchanged. Having a perfect shoe size is always a question mark for online shoppers, particularly when you shop for a child. There are plenty of options for kids to choose their shoes. From sporty shoes to a beautiful designer collection.

To update with the current size, every parent should measure the size after 3 to 4 months.

This article will describe everything you need to know about choosing the right shoe size for your children. We will provide you with some helpful age charts to help you decide on shoes for your kids.

How to Identify a Newborn and A Kid-Size?

This is quite simple but identifying the official terms is a bit tricky. The smallest size of the shoe is made for newborns because the larger sizes often fit children who are 4 or 5 years old or even older.

IMPORTANT! The footwear is often recognized with “T” which stands for toddlers e.g., 4T, 5T, 6T, 7T. From age 8–13, the measurements are typically marked with k that stands for “Kids,” e.g., 8 Kids, 9 Kids, 10 Kids, etc.

Lots of parents get confused. The average shoe size by age chart starts at size 1 and runs up to 7. Sometimes footwear brands will also help you out by holding their 1–7 size charts recorded with “T” and their other sizes designated as K.

For example, if you see a shoe that’s available in size “5 K size,” you know that it is the bigger kids’ 5, not a measurement for toddlers.

How Fast Feet Grow According to Child Age

This may vary from child to child, but on average, a toddler’s foot can grow about 1 inch per year. However, from the age of 2-5, the foot grows around 0.75 inches in one year.

Moreover, at the age of 6-11, the foot growth is 0.5 inches. It is important to measure your child’s feet to make sure they don’t wear oversize shoes. Because size feet can cause discomfort and issues related to health.

On average, foot growth in girls stops at the age of 13. However, in boys, foot development stopped at the age of 15 or 16.

Measuring Your Kid’s Shoes

The shoe size charts help you find the perfect size match for your child. Measuring the foot size is necessary to grasp the ideal size of the shoe for your kid. It can be measured easily at your home. You just need a paper pencil and a ruler.


Make sure that your kid stands on paper with the correct posture. Draw the length correctly with the help of the pencil. You can also ask for help if required.

In the second step, remove the child from the paper and draw a straight line behind the heel to the front of the longest part. Add around 1/4 inch to this pitch range. This is the actual foot length of your child. Remember to measure both feet because sometimes feet are different in size.

Common Things to Avoid When You Measure a Foot Size

Shoes easily mold the child’s foot, but this might cause stress in places where the shoe rubs against the foot. This might cause uncomfortable walking or running. Children grow up so fast. In the blink of an eye and they need a new pair of shoes.

Monitor their growth and measure their foot every couple of months. Just make sure that their feet don’t start to outgrow the shoe. You can set a note on your smartphone, so you remember to monitor.

If your little one starts footwear off, fettering around, or grinding their feet, it means that they have outgrown their shoes and need a new pair quickly as soon as possible.

Checking The Fitness of Shoes

Buying any shoe for your kid with an average shoe size by age chart is important yet tricky. Many people depend upon toe inspection, and many depend upon size charts. Check the tip of the shoe to check the space inside the shoe.

While checking the suitability of shoes mostly, kids use to bind their feet, and in return, wrong readings are collected. To get comfortable footwear, it is advised to purchase shoes with a small space between the heel and the rear of the shoe.

If you have already bought a fitted shoe, then rearrange the laces to get some comfortable space. The heels should not move up and down too much if it does then the show is not fit.

Final Verdict

We always encourage parents to go in-store shoe shopping for their kids to buy perfectly fitted and comfortable shoes instead of shopping online. The sizing guide above can help you to differentiate between toddlers’ and kids’ shoe sizes.

In some circumstances, two children of the same age may have different foot sizes. Measure the foot size carefully and check the age size chart carefully to grab the perfect size.

It is wise to advise you to estimate your kid’s feet every few months to bypass such concerns.
