Adult Shoe Size Conversion Chart

Shoes are an essential part of our everyday lives, but the global diversity of shoe size systems can make finding the perfect fit a daunting task. This comprehensive guide aims to demystify the process of converting shoe sizes between different regions and gender-specific standards. We will focus on four major sizing systems: European Union (EU), United States (USA), United Kingdom (UK), and Australia, considering both men's and women's sizes. Whether you're an avid traveler, an online shopper, or simply curious about international shoe sizing, this article will equip you with the knowledge to navigate the world of shoe sizes confidently.

Understanding the Basics

Before delving into the specifics of shoe size conversion, it's crucial to comprehend the underlying principles. Shoe sizes are typically determined by the length of the foot, but variations exist due to factors such as manufacturing techniques and regional preferences. It's important to note that shoe sizes are not standardized universally, leading to discrepancies between systems. However, conversion charts and formulas can provide a reliable starting point for finding the right fit across different sizing systems.

European Union (EU)

The EU shoe sizing system is widely used in many European countries. EU sizes are based on the length of the foot in centimeters. For instance, a size 40 in the EU system corresponds to a foot length of approximately 25 centimeters.

United States (USA)

The United States uses a different approach, employing a measurement called the Brannock Device. US shoe sizes are expressed in numbers for men and women, with half sizes available for finer adjustments.

United Kingdom (UK)

The UK shoe sizing system is similar to the EU system for men but differs for women. Men's UK sizes are comparable to EU sizes, whereas women's UK sizes follow a different scale. Women's UK sizes are typically a size smaller than their EU counterparts.


Australia also has its own shoe sizing system, which closely aligns with the UK system for men and US sytem for women.


Shoe sizes in Mexico typically follow the Mondopoint system, similar to ski and snowboard boots. The sizing is based on the length of the foot measured in millimeters. However, it's important to note that Mexico also uses a variation of the Brannock Device, which is commonly used in the United States. Mexican shoe sizes are often represented by numerical values, and half sizes are commonly available. It's worth mentioning that shoe sizes in Mexico can vary slightly from international sizing systems like EU, US, UK, and Australian sizes. To ensure the best fit, it's recommended to refer to conversion charts or consult local shoe sizing guidelines when purchasing shoes in Mexico. Trying on shoes and seeking assistance from knowledgeable staff can also help in finding the perfect fit.

Converting EU to USA Sizes

To convert EU sizes to US sizes for men, you can typically add 1.5 to the EU size. For women's sizes, adding 1 is usually sufficient. Keep in mind that these conversions are approximate, and it's always advisable to try shoes on or consult a conversion chart for accuracy.

Converting USA to EU Sizes

For men's sizes, subtracting 33.5 from the US size typically yields the corresponding EU size. Subtracting 32 should suffice for women's sizes. Remember that individual foot characteristics and shoe models may affect the accuracy of these conversions.

Converting EU to UK Sizes

To convert EU sizes to UK sizes, subtracting 1 from the EU size is generally reliable for men's shoes. However, for women's shoes, subtracting 2 is a common practice. Again, it's essential to consider personal fit preferences and variations between brands.

Converting UK to EU Sizes

Adding 1 to the UK size generally provides the EU size equivalent for men's shoes. For women's shoes, adding 2 is usually accurate. As always, keep in mind that personal comfort should take precedence over conversions.

Converting Australian Sizes

Australian sizes for men are usually equivalent to UK men's sizes. Australian sizes for women are equivalent to US women's sizes.

What is Mondopoint?

Mondopoint is a system used to measure and indicate the length and size of ski boots, snowboard boots, and some other types of footwear. Unlike traditional shoe sizing systems that rely on arbitrary numerical values or measurements in inches or centimeters, Mondopoint provides a more precise and standardized approach.In the Mondopoint system, the length of the foot is measured in millimeters. It involves measuring the distance from the heel to the longest toe while the foot is placed flat on the ground. This measurement is then used to determine the corresponding Mondopoint size.Mondopoint sizes are typically indicated by a numerical value followed by the letters "MP." For example, a ski boot size might be displayed as 275 MP. The numerical value represents the length of the foot in millimeters, and it directly correlates to the appropriate size of the boot.One of the key advantages of the Mondopoint system is its accuracy and consistency across different brands and models. This ensures a more precise fit and minimizes the chances of discomfort or performance issues associated with ill-fitting footwear. Additionally, the Mondopoint system allows for more fine-tuned adjustments as half sizes are commonly available.It's worth noting that Mondopoint sizes are specific to ski boots, snowboard boots, and some other sports footwear. They are not directly interchangeable with sizes from other shoe sizing systems, such as EU, US, UK, or Australian sizes. However, conversion charts and guidelines are available to help translate Mondopoint sizes into other sizing systems for reference or purchasing purposes.When selecting ski or snowboard boots, it is crucial to consult a professional boot fitter or refer to the manufacturer's sizing recommendations to ensure an optimal fit. Trying on different boots and seeking expert advice can greatly enhance your comfort, performance, and overall enjoyment on the slopes.


Navigating the intricacies of shoe size conversion between different systems can be challenging, but armed with the knowledge presented in this guide, you can confidently explore the world of international shoe sizes. Remember that these conversion methods serve as general guidelines and may vary depending on individual factors and brand-specific sizing practices. Whenever possible, try on shoes or refer to specific conversion charts provided by retailers. By understanding the basics of shoe sizing and utilizing conversion techniques, you can ensure a better fit and comfortable footwear, whether you're at home or exploring different corners of the globe.
