Frequently Asked Questions
How do I convert US shoe size to UK shoe size?
▼
For men, subtract 0.5 from the US size to get the UK size (e.g., US 10 = UK 9.5). For women, subtract 2 from the US size (e.g., US 8 = UK 6). This converter handles the math instantly — just select your size and see all conversions.
How do I convert US shoe size to EU shoe size?
▼
US to EU conversion is not a simple formula because the European sizing system uses different increments. Use this converter's lookup table for accurate results. For example, US Men's 10 is approximately EU 44, and US Women's 8 is approximately EU 38.5.
How do I measure my foot to find my shoe size?
▼
Stand on a piece of paper, trace your foot outline, and measure the longest distance from heel to toe in centimeters or inches. Use the measurement guide on this page to match your foot length to the correct shoe size in any system.
Why do shoe sizes vary between brands?
▼
Each brand uses different shoe lasts (the mold shapes used to make shoes). A size 10 in Nike may fit differently than a size 10 in Adidas. These conversion charts are based on standard sizing. Always check the specific brand's size chart when possible.
What is the difference between children's C and Y sizes?
▼
C stands for Child (toddler through young child, roughly ages 1-6) and Y stands for Youth (older children, roughly ages 6-12). Youth sizes pick up where child sizes end. After Youth size 7Y, children typically move to adult sizing.
Should I measure my feet in the morning or evening?
▼
Measure in the evening. Feet swell throughout the day due to walking and standing. Evening measurements give you the largest dimension, ensuring your shoes will be comfortable even at the end of the day.
What if my foot length is between two sizes?
▼
Always size up. A slightly larger shoe can be adjusted with thicker socks or insoles, but a shoe that is too small will cause discomfort and potential foot problems. This is especially important for running and athletic shoes.
Are men's and women's shoe sizes the same?
▼
No. Men's and women's sizes use different scales. A women's size is typically 1.5 to 2 sizes larger than the equivalent men's size. For example, a women's US 9 is approximately a men's US 7.5. EU sizes are the same for both genders.
How accurate are online shoe size converters?
▼
Online converters provide standard conversions that work for most shoes. However, fit varies by brand, shoe type (athletic vs. dress), and personal preference. Use these charts as a starting point and check brand-specific guides when ordering.
Is this shoe size converter free to use?
▼
Yes. This converter is completely free, runs entirely in your browser, and requires no registration. Your data is never sent to any server.

Tips for Using This Tool
Measure your feet in the evening
Feet swell throughout the day. Evening measurements capture your feet at their largest, preventing you from buying shoes that feel tight by afternoon.
Always size up if between sizes
A slightly larger shoe can be adjusted with insoles or thicker socks. A shoe that is too small causes blisters, bunions, and discomfort.
Use CM for the most accurate conversion
Centimeters measure actual foot length, which is consistent worldwide. When in doubt, measure your foot in CM and use that column.
Measure both feet
Most people have one foot slightly larger than the other. Measure both and use the larger measurement to find your size.
Consider sock thickness
If you wear thick socks (hiking, winter boots), measure your foot while wearing them. Thin dress socks may allow a slightly smaller size.
Check brand-specific charts too
These are standard conversions. Some brands run large (Converse) or small (Nike). Check the brand's own size chart alongside these conversions.
Kids grow fast — measure regularly
Children's feet can grow a full size every 3-4 months. Re-measure before every shoe purchase to avoid buying the wrong size.
EU sizes are unisex
European sizes are the same for men and women. An EU 40 is an EU 40 regardless of gender. Only US and UK sizes differ between genders.
Use Copy for shopping lists
Copy your converted sizes and keep them in your phone's notes. Reference them anytime you shop online or in stores abroad.
Width matters too
This chart converts length only. If you have wide (W) or narrow (N) feet, check the brand's width options separately after finding your length size.
