Understanding Different Shoe Size Systems
Buying shoes abroad can feel like decoding a secret code. The US, UK, and EU each start their number line in a different spot, while Japan simply measures the foot in centimeters. Here's the cheat sheet.
US vs UK
A men’s US 9 roughly equals a UK 8. Women’s sizes? Add one in the US system, subtract two in the UK. The two scales started from different baselines decades ago, which is why the numbers never line up neatly.
EU (European)
One unisex scale measured in Paris points (⅔ cm). An EU 43 fits both genders. Because EU sizes are based on foot length rather than gender, they’re the most straightforward system for cross-border shopping.
Japan & China
The number is your foot length in centimeters — simple but easy to forget. A Japan 27 means the shoe is built for a 27 cm foot. China follows a similar logic with slight rounding differences.
Australia
Australian sizes closely mirror UK sizes for men’s shoes. For women’s shoes, AU sizes are typically one size larger than UK sizes. If you know your UK size, you’re almost there.
Understanding these differences is crucial when converting sizes. The shoe conversion charts above will help you find your size and understand the differences across sizing systems.

Converting Women's Shoe Sizes
Finding the right shoe size when comparing between international systems can be tricky. Here are some common conversions.
A US women’s size 8 is approximately a European size 38–39.
Subtract two sizes from the US size to get the UK size. For example, a US women’s size 8 would be a UK size 6.
Add 15 to the US women’s size to get the Japanese size. So a US size 8 would be a Japanese size 23.
Australian women’s sizes are typically one size smaller than US sizes. A US 8 is roughly an AU 6.5–7.
Common Women's EU to US Conversions
| EU Size | US Equivalent |
|---|---|
| 38 | US women’s 7.5–8 |
| 39 | US women’s 8.5–9 |
| 40 | US women’s 9–9.5 |
| 41 | US women’s 10 |
Converting Men's Shoe Sizes
Men's shoe size conversions can also be complex. Here are some common conversions to help you find your fit.
A US men’s size 9 is approximately a European size 42–43.
Subtract one size from the US size to get the UK size. For instance, a US men’s size 10 would be a UK size 9.
Add 18 to the US men’s size to get the Japanese size. A US 9 is roughly a Japan 27.
Australian men’s sizes are the same as UK sizes. A US 10 is roughly an AU 9.
Common Men's EU to US Conversions
| EU Size | US Equivalent |
|---|---|
| 43 | US men’s 9.5–10 |
| 44 | US men’s 10–10.5 |
| 45 | US men’s 11 |
Converting Between Men's and Women's Sizes
Sometimes you find a style you love that's only available in the opposite gender's size. Here's how to convert.
Add 1.5 to the men’s size to get the women’s size. For example, a men’s size 8 would be a women’s size 9.5.
Subtract 1.5 from the women’s size to get the men’s size. So a women’s size 10 would be a men’s size 8.5.
Keep in mind that some brands add up to 1.5 sizes when converting between men's and women's sizes. Always check the specific brand's size guide.
How to Measure Your Foot
Measure Foot Length
- 1.Place a sheet of paper on a hard, flat floor.
- 2.Stand on the paper with your heel against a wall.
- 3.Wear the socks you'd normally wear with shoes.
- 4.Mark the tip of your longest toe with a pencil held straight up.
Measure Foot Width
- 1.While standing, mark the widest points of your foot on the paper.
- 2.Measure the distance between the two marks in centimeters.
- 3.Compare with the brand's width guide (narrow, medium, wide).
- 4.Repeat for both feet and use the wider measurement.
Find Your Size
- 1.Measure from the wall edge to your toe mark in centimeters.
- 2.Use the larger foot's measurement to find the right size.
- 3.Add 0.5–1 cm for a comfortable fit with some wiggle room.
- 4.Compare the measurement to the size chart above.
Shoe Sizing Tips
Sizing systems are not interchangeable
US, UK, EU, AU, China, and Japan each use different scales. A US 8 in women’s does not mean the same as a UK 8. Always convert using a chart rather than assuming the number transfers directly.
Women’s and men’s sizes overlap differently
A women’s US 8 is roughly a men’s US 6.5. If you’re buying unisex or cross-gender shoes, subtract about 1.5 from the women’s US size to get the men’s equivalent.
Brands fit differently
A US 9 from Nike can feel different from a US 9 from New Balance. Shoe lasts (the molds used to build the shoe) vary between brands, so always check the brand’s own size guide and read customer reviews about fit.
Measure in the afternoon or evening
Your feet swell slightly throughout the day. Measuring later gives you the most accurate reading for a comfortable fit, especially for shoes you’ll wear all day.
When in doubt, go half a size up
Shoes that are slightly too big can be adjusted with insoles or thicker socks. Shoes that are too small cause blisters, bunions, and discomfort that no break-in period will fix.
Measure both feet
Most people have one foot slightly larger than the other. Always use the larger foot’s measurement to pick your size. A difference of half a size between feet is completely normal.
FAQ on International Shoe Size Conversion Chart for Women & Men
How to Shop for Shoes Online
Shopping for shoes online? Here are some essential tips to ensure a perfect fit every time.
Check the return policy
Avoid the hassle of difficult returns or final sale restrictions by familiarizing yourself with the brand’s return policy before purchasing. Knowing this beforehand makes handling sizing issues much easier.
Consider shoe width
Foot measurements often don’t account for width. Look for shoes that offer varying widths such as “AA” (narrow), “B” (average), “C/D” (wide), or “E” (extra wide). You might also see “M” for medium, “N” for narrow, or “W” for wide.
Think about socks
Socks can affect the fit of your shoes. Try your shoes on with the type of socks you plan to wear to ensure the right fit. Thick winter socks versus thin summer socks can shift the fit by half a size.
Measure both feet
Feet are rarely identical in size. Measure both feet and use the larger measurement to avoid ordering shoes that are too small. A difference of half a size between feet is completely normal.
Measure late in the day
Feet tend to swell throughout the day. Measure your feet in the afternoon or evening to get the most accurate size for a comfortable all-day fit.
Consider all factors
Materials, manufacturing techniques, and embellishments can all affect how a shoe fits. Leather shoes may stretch over time, while synthetic materials hold their shape. Take these into account when selecting your size.
Read reviews
Sizing can vary between brands and styles. Check reviews to see if a shoe runs true to size, runs small, or runs large. Customer insights are often the best guide for getting the right fit on the first try.
