The table above provides a Universal Sock Size Chart, covering sizes from Child through to Adult X-Large. It is designed to give you a clear overview of typical sock sizing based on age group, and UK, EU and US shoe sizes are included. This makes it easier to find the right fit across age groups and international standards when shopping online.

However, please note that sizing can vary slightly between brands, so this chart should be used as a general reference only. If a specific product has a brand-supplied size guide, you’ll find it listed in the product description—we recommend referring to that first for the most accurate fit.

Considering More Than Just Size

In addition to shoe size, it is also important to consider the fabric, thickness, and intended use of socks. For example:

  • Cotton socks – Comfortable and breathable, suitable for everyday wear, but may shrink slightly after washing.
  • Wool or thermal socks – Thicker and warmer, ideal for cold weather, but may fit more snugly.
  • Stretch or blended socks – Include elastane or spandex for flexibility, which helps them stay in place.
  • Performance or athletic socks – Often feature moisture-wicking fabrics, extra cushioning, or compression for enhanced comfort during sports or exercise.

Choosing the Right Size

  • If you’re between sizes or unsure, we generally recommend sizing up for added comfort.
  • This is particularly helpful for growing children or those who wear thicker socks.

Why This Guide Matters

We know that finding the right sock size can sometimes be a challenge — especially with the wide range of brands, each using their own measurement systems. That’s why we’ve created this comprehensive Sock Size Chart Guide to help you make confident, informed decisions when shopping online with us.

Final Note

This general guide is a helpful starting point, but it’s important to remember that sock sizes can vary slightly between brands, styles, and fabric types. Whenever possible, we strongly recommend checking the brand-specific size guides provided on our product pages for the most accurate fit.

Pro Tips for Measuring Socks

  • Measure foot length: Use a ruler or tape from the tip of your longest toe to the back of your heel.
  • Check shoe size: Compare your measurement to UK, EU or US sizes to find the correct sock size.
  • Consider foot width: Some socks are designed for narrow or wide feet—check product details if needed.
  • Account for stretch: Socks with elastane or spandex may fit a range of sizes.
  • Think about intended use: Athletic or performance socks may fit snugly, while casual or thermal socks may have a looser fit.
  • When in doubt, size up: Especially for children, growing teens, or thicker sock types to ensure comfort.

Brand-Specific Size Guides

On our website, you’ll find these brand-specific size guides directly under the product description on each product page. These charts are provided by the manufacturers and are the most accurate reference for that particular brand. If a brand-specific guide is listed, we encourage you to follow it rather than relying solely on this general chart.

Below is a list of brands currently stocked by A7 Sports, each offering its own brand-specific size chart for reference:
