Are you staring at a shoe box trying to figure out what US L stands for? You’re not alone. Shoe sizing can be confusing, with different countries and brands using various labels and systems. If you’re short on time, here’s a quick answer: US L stands for ‘Long’ and corresponds to a men’s shoe size 13 in the standard US size scale.

In this comprehensive guide, we’ll cover everything you need to know about US shoe sizes, what the different width designations mean, how to convert to international sizing, and tips for finding the right fit.

Overview of US Shoe Sizing System

The US shoe sizing system is widely used and recognized around the world. It provides a standardized way to measure and label shoe sizes, ensuring that consumers can easily find the right fit for their feet.

Understanding how the US shoe sizing system works is essential when purchasing shoes, both online and in-store.

Brief history and standardization

The US shoe sizing system has a rich history that dates back to the early 19th century. Initially, there was no standardized shoe sizing system, and manufacturers used their own measurements, leading to inconsistencies and confusion.

However, in the 1880s, the Brannock Device was invented, which revolutionized the shoe sizing process. This tool allowed for accurate foot measurements and the establishment of a standardized shoe sizing system.

The US shoe sizing system is based on the length of the foot in inches. Whole and half sizes are available, with the smallest size typically being a size 1 for infants. As the foot length increases, the corresponding shoe size also increases.

Adult sizes usually start at size 4 for women and size 6 for men.

Difference between men’s and women’s sizing

One notable difference in the US shoe sizing system is the distinction between men’s and women’s sizing. Women’s shoe sizes are typically two sizes smaller than men’s. For example, a men’s size 8 is equivalent to a women’s size 10.

This difference accounts for the variations in foot shape and size between genders.

It’s important to note that the US shoe sizing system is not the same as the European shoe sizing system. In Europe, shoe sizes are typically measured in centimeters, and the sizing scale is different. Therefore, it’s crucial to consult a conversion chart when purchasing shoes from different regions.

Size width designations

In addition to length, the US shoe sizing system also includes width designations. These designations indicate the width of the shoe, ensuring a proper fit for individuals with different foot widths. The most common width designations for both men and women are narrow (B), medium/standard (D), and wide (E).

However, there are also additional widths available for individuals with specific foot requirements, such as extra wide (EE) or extra narrow (AAA).

It’s worth mentioning that shoe sizes and width designations can vary slightly between different shoe brands and manufacturers. Therefore, it’s always recommended to try on shoes or consult the brand’s specific size guide when making a purchase.

US Size L Corresponds to Size 13 in Men’s

US shoe sizes can sometimes be confusing, especially when it comes to larger sizes. If you’ve come across the term “US Size L” in shoe sizing, it actually corresponds to a size 13 in men’s shoes. This size is considered to be on the larger end of the spectrum, catering to individuals with bigger feet.

US men’s sizing from AA to EEE

In the United States, men’s shoe sizes typically range from AA (narrowest) to EEE (widest). The letter “L” represents the widest width available, indicating that the shoe is designed to accommodate individuals with broader feet.

These wider widths are essential for providing comfort and preventing discomfort or pain associated with tight-fitting shoes.

It’s important to note that shoe widths can vary between brands and styles, so it’s always a good idea to try on shoes before making a purchase, especially if you have specific width requirements.

Comparison to international sizing charts

When comparing US shoe sizes to international sizing charts, it’s essential to consider that different countries may have slightly different systems. However, in general, a US Size L (size 13) in men’s shoes is equivalent to:

Country Equivalent Size
United Kingdom Size 12.5
Europe Size 47
Japan Size 31
Australia Size 12.5
Canada Size 12.5

These conversions provide a general guideline, but it’s always best to check with the specific brand or retailer for accurate size conversions.

Determining the Right Shoe Size and Fit

When it comes to finding the perfect pair of shoes, it’s important to consider both the size and fit. While these terms are often used interchangeably, they actually refer to different aspects of the shoe.

Understanding the difference between size and fit can help you make the right choice and ensure maximum comfort.

Difference between size and fit

The size of a shoe refers to the numerical measurement assigned to it, usually indicated by a number such as US L. This number represents the length of the shoe, typically measured in inches or centimeters.

On the other hand, the fit of a shoe refers to how well it conforms to the shape of your foot. A shoe can be the correct size but still not fit properly due to factors such as width, arch type, or the purpose of the shoe.

Tips for measuring feet properly

Measuring your feet correctly is crucial for finding the right shoe size and fit. Here are some tips to ensure accurate measurements:

  • Measure your feet at the end of the day when they are slightly swollen.
  • Use a ruler or measuring tape to measure the length of your foot from the heel to the longest toe.
  • Measure both feet and use the larger measurement as your shoe size.
  • Consider getting a professional fitting at a shoe store for more accurate measurements.

Factors that affect fit

Several factors can affect the fit of a shoe, including:

  • Width: Shoes come in various widths, ranging from narrow to wide. It’s important to choose a width that accommodates the width of your foot.
  • Arch type: Feet can have low arches, high arches, or be neutral. Different shoe styles cater to different arch types, so it’s important to find a shoe that provides adequate support.
  • Purpose: The purpose of the shoe, such as running or hiking, can also impact the fit. Certain activities may require specific features like cushioning or stability.
  • Brand: Different shoe brands may have slightly different sizing and fit standards. It’s always a good idea to try on shoes from different brands to find the one that fits your feet best.

It’s important to remember that shoe size and fit can vary between brands and even between different shoe styles within the same brand. Therefore, it’s always recommended to try on shoes before making a purchase, especially when shopping online.

Finding Shoes in Size L or 13

If you have larger feet and struggle to find shoes in size L or 13, don’t worry, you’re not alone. Many individuals face this challenge and have difficulty finding the right fit. However, with the rise of online retailers and increased awareness of varying foot sizes, there are now more options available than ever before.

Online retailers that carry large sizes

When it comes to finding shoes in size L or 13, online retailers have become a go-to solution for many people. Websites such as Zappos, Amazon, and Nordstrom offer a wide range of options in larger sizes.

These retailers often provide detailed size charts and customer reviews to help you make an informed decision. Additionally, some websites specialize in offering shoes specifically for individuals with larger feet, providing a more extensive selection.

It’s important to note that not all brands offer extended sizes, so it may be necessary to explore different retailers and brands to find the perfect fit. Keep in mind that shoe sizes can vary between brands, so it’s always a good idea to consult the specific brand’s size chart before making a purchase.

In-store options for trying on size 13 shoes

While online shopping provides convenience, trying on shoes in person can be a preferable option for many. If you prefer to try on shoes before making a purchase, there are still options available for finding size 13 shoes in-store.

Sporting goods stores, specialty shoe stores, and department stores often carry a range of sizes, including size 13.

It’s important to keep in mind that not all stores will have a wide selection of larger sizes readily available. It may be beneficial to call ahead or check the store’s website to ensure they have the size and style you are looking for in stock.

Tips for wide or narrow feet

Individuals with wide or narrow feet may face additional challenges when it comes to finding the right fit in size L or 13 shoes. Here are a few tips to help you find shoes that accommodate your specific foot shape:

  • Wide feet: Look for shoes that offer a wide width option. Many shoe brands now offer a variety of widths to cater to different foot shapes. Additionally, opt for shoes with a roomy toe box to provide ample space for your toes.
  • Narrow feet: Consider shoes with adjustable features, such as straps or laces, to help customize the fit. Look for brands that offer narrower width options. It may also be helpful to try on different styles and brands to find the best fit for your narrow feet.

Remember, finding the right shoe size is essential for comfort and foot health. Don’t settle for ill-fitting shoes; explore your options and find the perfect fit for your feet.

Kids and Juniors Sizing Compared to Adults

Understanding the differences between kids and adult shoe sizes is essential when shopping for footwear for children. Kids shoe sizes are typically labeled differently than adult sizes, with the addition of the letter “US L” in some cases.

Let’s delve into the details of how kids and juniors sizing compares to adult sizes.

How kids sizes convert to adult

When it comes to converting kids shoe sizes to adult sizes, it can be a bit confusing. The “US L” in shoe sizes denotes that the size is for little kids, typically ranging from toddlers to about age 10.

To convert kids sizes to adult sizes, you’ll generally need to add about two sizes to the child’s shoe size. For example, if a child wears a size 3 in kids shoes, they would typically wear a size 5 in adult shoes.

It’s important to note that this conversion is not an exact science, as shoe sizes can vary between brands and styles. It’s always best to try on shoes or consult a size chart provided by the manufacturer to ensure the best fit.

Teen/youth versus junior sizing

In addition to kids sizes, there are also teen/youth and junior sizes available. Teen/youth sizes typically cover older kids and teenagers, usually ranging from ages 10 to 14. Junior sizes, on the other hand, are designed for older teenagers and young adults, typically ranging from ages 14 to 18.

Teen/youth sizes are often labeled with a “Y” or “T” after the number size. For example, a size 6Y or 6T would indicate a teen/youth size. Junior sizes, on the other hand, are typically labeled with a “J” after the number size. For example, a size 6J would indicate a junior size.

Unisex sizing for kids shoes

When it comes to kids shoes, there are also unisex sizes available. Unisex sizes are designed to fit both boys and girls, eliminating the need for separate gender-specific sizing. These sizes are typically labeled with a “U” after the number size. For example, a size 6U would indicate a unisex size.

Unisex sizing can be particularly useful when purchasing shoes for younger children who may not have specific gender preferences or when looking for more gender-neutral shoe options.

Understanding the differences between kids and adult shoe sizes, as well as the variations in sizing for teens and juniors, can help ensure a proper fit when shopping for footwear. Remember, it’s always a good idea to consult a size chart or try on shoes to find the best fit for your child’s growing feet.


So in summary, US L corresponds to a size 13 in men’s shoes using the standard US sizing scale. But finding the optimal fit involves more than just size – the width, purpose, brand and shape of your feet all play a role.

With an understanding of sizing designations and options for larger sizes, you can confidently shop for shoes that fit comfortably. If you have any other sizing questions, don’t hesitate to ask an associate at your local shoe store.
