Shoes come in all shapes and sizes, and trying to figure out if boys’ and girls’ sizes are equivalent can be confusing. If you’re in a rush, here’s the quick answer: no, boys’ and girls’ shoe sizes are not the same.

In this comprehensive guide, we’ll explain the key differences between boys’ and girls’ sizing, why the sizing differs, provide size conversion charts, and give tips for finding the right shoe size for kids.

Key Differences Between Boys’ and Girls’ Shoe Sizes

Boys’ sizes run larger

One key difference between boys’ and girls’ shoe sizes is that boys’ sizes tend to run larger. This means that if you are looking for shoes for a boy, you will generally need to choose a larger size compared to girls’ shoes.

This is because boys’ feet tend to be slightly bigger on average than girls’ feet. It’s important to keep this in mind when shopping for shoes for boys to ensure a proper fit and avoid discomfort.

Girls’ sizes correlate to women’s sizes

Another important difference is that girls’ shoe sizes often correlate to women’s sizes. This means that as girls grow into women, their shoe sizes may increase accordingly. For example, a girl who wears a size 5 in girls’ shoes may eventually transition to a size 7 in women’s shoes.

This correlation between girls’ and women’s shoe sizes can be helpful for girls as they transition into adulthood and need to find appropriate footwear.

Sizing systems differ

It’s also worth noting that the sizing systems for boys’ and girls’ shoes can differ. While both use numerical sizes, the specific measurements may vary between the two categories. For example, a size 5 in boys’ shoes may not be the same as a size 5 in girls’ shoes.

It’s important to consult the sizing charts provided by shoe manufacturers to ensure an accurate fit. Additionally, it’s always a good idea to try shoes on before making a purchase to ensure proper sizing and comfort.

Why Boys’ and Girls’ Shoe Sizes Differ

Many people wonder why boys’ and girls’ shoe sizes differ. There are several factors that contribute to this difference, including differences in foot shape and market segmentation.

Differences in Foot Shape

One of the main reasons why boys’ and girls’ shoe sizes differ is due to differences in foot shape. Generally, boys’ feet tend to be wider and have a higher instep compared to girls’ feet. This means that boys may require shoes that provide more width and support, while girls may need shoes that are narrower and provide a different level of arch support.

These differences in foot shape can impact the fit and comfort of the shoes, which is why separate sizing is often necessary.

According to a study conducted by the American Orthopaedic Foot & Ankle Society, boys’ feet tend to be on average 10% wider than girls’ feet. This difference in foot width plays a significant role in determining the appropriate shoe size for each gender.

Additionally, the study found that boys’ feet also tend to be longer on average compared to girls’ feet.

Market Segmentation

Another reason for the difference in boys’ and girls’ shoe sizes is market segmentation. Shoe manufacturers and retailers often separate their shoe offerings by gender in order to better cater to the specific needs and preferences of each gender.

This means that they may develop different shoe styles and sizes for boys and girls based on market research and consumer demand.

Market segmentation allows for the creation of shoes that are designed to meet the unique requirements of boys and girls. For example, boys’ shoes may be designed to be more durable and provide better support for active play, while girls’ shoes may focus more on style and fashion.

By offering separate sizes for boys and girls, shoe companies can better serve their target customers and provide them with shoes that fit well and meet their specific needs.

Boys’ to Girls’ Shoe Size Conversion Charts

When it comes to buying shoes, one question that often arises is whether boys’ and girls’ shoe sizes are the same. The answer is no – boys’ and girls’ shoe sizes are different. However, with the help of shoe size conversion charts, it is possible to find the equivalent size in the opposite gender’s shoe range.

Understanding Shoe Size Conversion Charts

Shoe size conversion charts provide a convenient way to convert between boys’ and girls’ shoe sizes. These charts typically list the corresponding sizes for each gender, allowing you to determine the appropriate size.

For example, if you wear a boys’ size 5, you can refer to the conversion chart to find out that it is equivalent to a girls’ size 6.5.

It’s important to note that shoe sizes can vary slightly between different brands and manufacturers. Therefore, it is always a good idea to consult the specific brand’s size chart to ensure an accurate conversion.

How to Use a Shoe Size Conversion Chart

Using a shoe size conversion chart is a straightforward process. Simply locate your current shoe size in the column corresponding to your gender, and then find the corresponding size in the opposite gender’s column.

For example, if you wear a boys’ size 4, you would look for the girls’ size that aligns with it on the chart.

It’s worth mentioning that the conversion between boys’ and girls’ shoe sizes is not a direct one-to-one correlation. In most cases, girls’ sizes tend to be slightly smaller than boys’ sizes. Therefore, it is important to consult the chart to ensure an accurate conversion.

Online Resources for Shoe Size Conversion

There are several websites that offer online shoe size conversion charts, making it easy to find the equivalent size between boys’ and girls’ shoes. Some popular resources include:

These websites provide comprehensive charts that allow you to convert between boys’ and girls’ shoe sizes effortlessly. It’s always a good idea to check multiple sources to ensure accuracy.

Tips for Finding the Right Shoe Size

Have feet professionally measured

One of the best ways to ensure you find the right shoe size is to have your feet professionally measured. Shoe sizes can vary between brands, and even within the same brand, so it’s important to get an accurate measurement.

A professional shoe fitter will be able to measure both the length and width of your feet, and recommend the appropriate size.

According to Healthy Feet Store, your shoe size can change over time due to factors such as weight gain, pregnancy, and aging. Therefore, it’s a good idea to have your feet measured periodically to ensure you’re wearing the correct size.

Use the ‘thumb-width’ test

If you’re unable to have your feet professionally measured, you can use a simple test to get an approximate idea of your shoe size. It’s called the ‘thumb-width’ test. Place your thumb on the longest toe of your foot and use your other hand to measure the width of your thumb.

This width should be similar to the width of the shoe at its widest point.

Keep in mind that this is just a rough estimate and may not be as accurate as a professional measurement. It’s always best to try on shoes and walk around in them to determine the right fit.

Try shoes on in the afternoon

Feet tend to swell throughout the day, especially in warm weather or after physical activity. To account for this, it’s recommended to try on shoes in the afternoon or evening when your feet are at their largest.

This will ensure that you choose a size that accommodates any swelling and provides enough room for comfort.

According to Barking Dog Shoes, it’s important to note that one foot is often slightly larger than the other. When trying on shoes, always fit them to the larger foot to ensure a comfortable fit.

Allow room for growth

When buying shoes, especially for children, it’s important to allow room for growth. Children’s feet can grow quickly, so it’s recommended to choose a shoe size that provides about a thumb’s width of space between the longest toe and the front of the shoe.

This will allow for growth and ensure that the shoes last longer.

For adults, it’s also a good idea to choose a shoe size with a bit of extra room to accommodate any swelling or foot conditions that may arise. Shoes that are too tight can cause discomfort, blisters, and other foot problems.

By following these tips, you can increase the chances of finding the right shoe size for both comfort and proper foot health.


When shopping for kids’ shoes, don’t assume a size that fits for one gender will fit the other. Boys’ and girls’ sizes differ due to variations in foot shape and market segmentation. Use size charts and in-store fittings to find the perfect pair.
