Buying women’s shoes online can be confusing when different countries use different sizing systems. A shoe labeled size 38 in Europe may not look familiar to someone used to US sizes, while a UK size may seem even more confusing if you have never compared shoe charts before. This is why a women’s shoe size conversion chart is useful for shoppers, retailers, travelers, and anyone buying footwear from international brands.
Women’s shoe size conversion helps you compare EU, US, and UK shoe sizes so you can choose the closest possible fit. While size charts are helpful, it is important to remember that shoe sizing is not perfectly universal. Different brands, shoe shapes, materials, and foot widths can affect how a shoe feels even when the size number looks correct.

Quick Answer: Women’s Shoe Size Conversion
A general women’s shoe size conversion between EU, US, and UK sizes looks like this:
| EU Size | US Women’s Size | UK Women’s Size |
|---|---|---|
| 36 | 5.5–6 | 3.5–4 |
| 37 | 6.5–7 | 4.5 |
| 38 | 7.5–8 | 5.5 |
| 39 | 8.5 | 6 |
| 40 | 9–9.5 | 6.5–7 |
| 41 | 10–10.5 | 7.5–8 |
These conversions are approximate because brands may use slightly different sizing standards. Always check the brand’s own size guide when available.
Why Women’s Shoe Size Conversion Matters
Shoe sizing is not the same everywhere. The United States, United Kingdom, and Europe each use different measurement systems. A woman who wears a US size 8 may need an EU 38 or 39 depending on the brand, while the same shoe may be listed as a UK 5.5 or 6.
This matters most when buying shoes online. Without trying the shoe on first, you need a reliable way to compare sizes. A conversion chart gives you a starting point and helps reduce the chances of ordering shoes that are too tight, too loose, or uncomfortable.
Common Situations Where Conversion Helps
- Buying shoes from international websites.
- Shopping from European, American, or British brands.
- Comparing size labels on sneakers, heels, boots, and sandals.
- Ordering gifts for someone in another country.
- Checking whether a size 37, 38, 40, or 41 matches your usual size.
- Traveling and shopping abroad.
A good conversion chart saves time, improves confidence, and helps shoppers make better purchasing decisions.
Understanding EU, US, and UK Women’s Shoe Sizes
Before using a shoe conversion chart, it helps to understand how each sizing system works. Although they all describe shoe size, they are based on different measurement traditions.
EU Women’s Shoe Sizes
European shoe sizes usually use numbers such as 36, 37, 38, 39, 40, and 41. EU sizing is common across many European countries and is also widely used by international fashion brands.
EU sizes are usually not separated by gender in the same way as US sizing, although women’s shoes are made on different lasts and shapes than men’s shoes. This means an EU 38 women’s shoe and an EU 38 men’s shoe may not fit the same way because the shoe shape can differ.
US Women’s Shoe Sizes
US women’s shoe sizes typically use numbers such as 6, 7, 8, 9, and 10. Half sizes are also common, such as 7.5 or 8.5. US sizing is widely used by American shoe brands and retailers.
One important thing to remember is that US women’s sizes are different from US men’s sizes. A women’s US 8 is not the same as a men’s US 8.
UK Women’s Shoe Sizes
UK women’s shoe sizes usually run smaller numerically than US women’s sizes. For example, a US women’s size 8 is often close to a UK women’s size 5.5 or 6.
UK sizing is commonly used by British footwear brands, but it may also appear on international shoe labels.
Women’s Shoe Size Conversion Chart
The chart below gives a practical comparison of common women’s shoe sizes across EU, US, and UK systems.
| EU Size | US Women’s Size | UK Women’s Size | Approx. Foot Length |
|---|---|---|---|
| 35 | 5 | 2.5–3 | 22.0 cm |
| 36 | 5.5–6 | 3.5–4 | 22.5–23.0 cm |
| 37 | 6.5–7 | 4–4.5 | 23.5 cm |
| 38 | 7.5–8 | 5–5.5 | 24.0–24.5 cm |
| 39 | 8.5 | 6 | 25.0 cm |
| 40 | 9–9.5 | 6.5–7 | 25.5 cm |
| 41 | 10–10.5 | 7.5–8 | 26.0–26.5 cm |
| 42 | 11 | 8.5–9 | 27.0 cm |
This chart should be used as a guide, not an absolute rule. Shoe sizing can vary by brand, style, material, and country.
What Is Size 37 in Women’s Shoes?
Women’s size 37 shoes are commonly equivalent to approximately a US women’s size 6.5 to 7 and a UK women’s size 4 to 4.5.
Size 37 Conversion
| EU Size | US Women’s Size | UK Women’s Size |
|---|---|---|
| 37 | 6.5–7 | 4–4.5 |
If you usually wear a US women’s 7, EU 37 may be a good starting point. However, if you have wider feet or are buying pointed heels, boots, or narrow sneakers, you may need to check the brand’s specific size chart.
What Is Size 38 in Women’s Shoes?
Women’s size 38 shoes usually convert to approximately a US women’s size 7.5 to 8 and a UK women’s size 5 to 5.5. This is one of the most common women’s shoe sizes in many international charts.
Size 38 Conversion
| EU Size | US Women’s Size | UK Women’s Size |
|---|---|---|
| 38 | 7.5–8 | 5–5.5 |
If you are shopping for size 38 women’s shoes online, check whether the brand recommends sizing up or down. Some fashion brands run narrow, while athletic shoes may offer more structured sizing based on foot length.
For quick conversions between EU, US, and UK systems, you can use the Shoe Size Converter instead of checking multiple charts manually.
What Is Size 40 in Women’s Shoes?
Women’s size 40 shoes usually convert to approximately a US women’s size 9 to 9.5 and a UK women’s size 6.5 to 7. This size is common in European footwear and is often seen in sneakers, boots, sandals, heels, and designer shoes.
Size 40 Conversion
| EU Size | US Women’s Size | UK Women’s Size |
|---|---|---|
| 40 | 9–9.5 | 6.5–7 |
If you normally wear a US women’s 9, EU 40 may be a good match. If you wear a US 9.5, some brands may recommend EU 40 while others may suggest EU 41. This is why checking foot length in centimeters can be more reliable than using size numbers alone.
What Is Size 41 in Women’s Shoes?
Women’s size 41 shoes usually convert to approximately a US women’s size 10 to 10.5 and a UK women’s size 7.5 to 8. This size is widely available from many European and international footwear brands.
Size 41 Conversion
| EU Size | US Women’s Size | UK Women’s Size |
|---|---|---|
| 41 | 10–10.5 | 7.5–8 |
If you are between sizes, consider the shoe type. For tight styles such as pointed heels, narrow flats, or structured boots, sizing up may feel more comfortable. For sandals or open-toe shoes, the regular converted size may work better.
How to Measure Your Foot for Better Shoe Size Conversion
Using a size conversion chart is helpful, but measuring your foot gives you a more accurate starting point. Foot length in centimeters or inches can reduce confusion when comparing international shoe sizes.
Step-by-Step Foot Measuring Method
- Place a blank sheet of paper on a flat floor.
- Stand on the paper with your heel against a wall.
- Mark the longest point of your foot, usually the big toe or second toe.
- Measure from the wall edge to the mark using a ruler.
- Repeat for the other foot because one foot may be slightly larger.
- Use the larger measurement when choosing shoe size.
Measure your feet at the end of the day if possible. Feet can swell slightly after walking or standing, so evening measurements often give a more realistic fit.
Why Shoe Sizes Vary Between Brands
Even when two shoes show the same size, they may not fit exactly the same. Shoe sizing can vary because brands use different lasts, materials, shapes, and manufacturing standards.
Shoe Shape
A pointed-toe shoe usually feels tighter than a round-toe shoe in the same size because there is less room at the front.
Material
Leather may stretch slightly over time, while synthetic materials may remain firmer. Knitted sneakers may feel more flexible than structured dress shoes.
Brand Fit
Some brands run narrow, wide, small, or large. Customer reviews often mention whether a shoe is true to size.
Shoe Type
Boots, heels, sneakers, sandals, loafers, and flats may all fit differently even if the size label is the same.
Tips for Buying Women’s Shoes Online
Online shopping is convenient, but choosing the right size requires careful checking. These tips can help reduce returns and improve your chances of getting a comfortable fit.
Check the Brand’s Size Chart
Always compare your usual size with the brand’s official chart. A general conversion chart is helpful, but brand-specific guidance is usually more accurate.
Read Customer Reviews
Reviews often reveal whether a shoe runs small, large, narrow, or wide. Look for comments from shoppers with similar foot shapes.
Check Return Policies
Before ordering internationally, check whether returns or exchanges are allowed. International returns can sometimes be expensive or limited.
Consider Width
Length is only one part of shoe fit. If you have wide feet, narrow shoes may feel uncomfortable even when the length is correct.
Think About Socks
Boots and sneakers may need extra room for socks, while sandals and heels may fit better with a closer shape.

Common Mistakes in Women’s Shoe Size Conversion
Women’s shoe size conversion is useful, but mistakes can still happen when shoppers rely only on a single chart.
Assuming Every Brand Fits the Same
A US size 8 from one brand may not feel identical to a US size 8 from another brand. Always check brand-specific sizing when possible.
Ignoring Foot Width
Length conversion does not automatically solve width problems. Shoes that are too narrow can cause discomfort even if the length is correct.
Forgetting Half Sizes
Some EU conversions fall between two US or UK sizes. If you usually wear a half size, compare foot length before deciding.
Not Measuring Both Feet
Many people have one foot slightly larger than the other. Choose shoes based on the larger foot for better comfort.
