Summary of this article：Quickly translating EU shoe sizes to US women's sizes will help you prevent returns if you're ordering from EU-based online retailers or purchasing from European brands. The most dependable approach is to consult a size chart and, whenever feasible, measure your foot length (in cm or mm), as these conversions are not entirely standardized.
Quick EU to US women’s size chart (common conversion)
One of the most popular reference charts for women's shoes is this one:
•EU 35 → US Women’s 4
•EU 36 → US Women’s 5
•EU 37 → US Women’s 6
•EU 38 → US Women’s 7
•EU 39 → US Women’s 8
•EU 40 → US Women’s 9
•EU 41 → US Women’s 10
•EU 42 → US Women’s 11
(you may also see ranges like "EU 39–40 = US 9," which indicates modest fit discrepancies, depending on the brand.)
The most accurate method: match by foot length (cm/mm)
Foot length is more reliable than size conversion alone because sizing varies somewhat between brands. A useful guide connecting EU size, US women's size, and foot length can be found below:
| EU | US Women’s | Foot length |
| 35 | 4 | 21.2 cm (212 mm) |
| 36 | 5 | 22.0 cm (220 mm) |
| 37 | 6 | 22.9 cm (229 mm) |
| 38 | 7 | 23.7 cm (237 mm) |
| 39 | 8 | 24.6 cm (246 mm) |
| 40 | 9 | 25.4 cm (254 mm) |
| 41 | 10 | 26.2 cm (262 mm) |
| 42 | 11 | 27.0 cm (270 mm) |
How to measure your foot length at home (fast + accurate)
1. Take a measurement in the evening when your feet are a little swollen.
2. Put on the socks you intend to wear with the shoes.
3. To ensure accuracy, trace your foot while standing on paper.
4. Take a millimeter measurement from the heel to the longest toe.
5. If the two feet are different, use the greater foot measurement.
Next, use the foot-length table above or a brand's size guide to compare your measurements.
Common fit issues (and how to choose the right size)
If you are between sizes
•For comfort, a lot of individuals go up half a size in their sneakers.
•If the toe area of heels or pointed shoes is snug, size up may be helpful.
•Boots: Consider the thickness of the socks; half-size up is typically recommended.
If you have wider feet
EU/US size does not accurately reflect width if your feet are wider. If width options are available, look for them or read reviews that say "runs wide" or "runs narrow."
Brand differences are real
Different brands may fit differently even if the EU size is the same. Whenever feasible, rely on foot length, but use conversion charts as a guide.
FAQ
Is EU sizing the same for all European countries?
Not entirely. Even while they are generally comparable, there isn't a single, uniform standard for all brands, particularly when it comes to athletic and stylish shoes.
What is EU 38 in US women’s?
Typically, it is a size 7 for US women.
What is EU 40 in US women’s?
Typically, it is a size 9 for US women.
Why do some charts show different conversions?
Because different shoe molds, or "lasts," are used by different brands, sizes may be rounded slightly, leading to minor discrepancies or size ranges.
Conclusion
Start with the conventional formula (EU 35 = US 4 through EU 42 = US 11) to convert euro shoe sizes to US women's sizes. However, for the best exact fit, always confirm using foot length in cm or mm, especially when shopping across different brands or shoe styles.
