Your sock size is determined by your shoe size. Simply enter your shoe size (in US, UK, or EU) and your gender above, and the calculator will return your recommended sock size label (XS through XXL) along with the corresponding size ranges across all systems.
US sock sizes typically correspond to your US shoe size. For men, sizes range from XS (shoe 2.5–5) up to XXL (shoe 15–17). Women's sizes go from S (shoe 4.5–7) to L (shoe 10–11.5). The sock size is essentially your shoe size, sometimes expressed as a range like 8–9.5.
Yes. Men's and women's sock sizes are based on different shoe size scales. A women's shoe size 8 and a men's shoe size 8 are different foot lengths. Use the correct gender setting in the calculator to get an accurate sock size recommendation. Many unisex socks follow men's sizing.
Kids' sock sizes can be found by entering your child's shoe size and selecting 'Kids' as the category. You can also enter the child's age as a rough guide — for example, shoe sizes 9–11.5 (US Kids) typically fit ages 3–5, while sizes 3–6 fit ages 8–10. Shoe size is more accurate than age alone.
These are general sock size labels used by many brands. XS covers the smallest shoe sizes, while XXL covers the largest. Each label maps to a range of US shoe sizes — for example, M for men typically means US shoe sizes 8–9.5. Our calculator matches your shoe size to the correct label automatically.
EU shoe sizes can be entered directly into this calculator. For example, EU 41–42 typically corresponds to a men's Medium sock size (US 8–9.5, UK 7.5–9). The calculator handles the conversion from EU shoe sizing to the appropriate sock size label and range for you.
If your shoe size is on the border between two sock sizes, it's generally recommended to size up. A slightly larger sock will still fit comfortably, whereas a sock that's too small may feel tight and wear out faster. The calculator will show the size range closest to your shoe size.
Not always. While most brands follow similar sizing conventions, there can be minor differences between manufacturers. Always check the specific brand's size chart when shopping. The sizes this calculator provides are based on widely accepted industry standards used by major sock brands.
