Shoe Size Conversion Chart: US to UK to EU Sizes and More

Shoe size measurements differ between countries, and within that, between genders, shoe styles, and even brands. We have the definitive conversion charts to help you decode shoe sizes here while also explaining important nuances like how sneakers tend to run bigger than dress shoes and how width matters.

Did you know that there’s actually an international measurement for shoe sizes? It’s called Modopoint, and just about no one uses it.

Instead, we’re left to our own devices, Googling terms like ‘euro shoe size to us’ or ‘men’s shoe size chart,’ searching up size conversion calculators, and frantically looking for charts to compare to other charts.

We’re literally living in a world of shoe size confusion.

So that’s why we’ve created this guide, complete with conversion charts – and a handy conversion calculator too.

Shoe Size Conversion Charts for Men and Women

See below for our men’s shoe size conversion chart, and the women’s chart below that. But before you do, there are some key pieces of information to keep in mind:

• Men’s sizes are smaller than women’s by exactly 1.5: If a particularly unisex shoe style runs out in your size, choose a size that’s 1.5 higher in the women’s.
• US sizes are one unit larger than UK sizes: You may be a size 10 when looking at American shoes, but you’d be a size UK9 for the equivalent shoe.
• US size to EU size conversions don’t account for half sizes: For example, a US 7.5 is a size 41 in France or Spain. Both a US 9 and 9.5 are European 43s. See the chart for the comprehensive, nuanced comparison.
• Pay attention to Chinese sizes, too: To convert a CN shoe size to a US shoe size, you’ll subtract anywhere from 32.5 to 35 from the Chinese size to get the American size. The bigger the size, the more you’ll subtract.

This can all get pretty confusing, but that’s where the chart comes in.

Shoe Width Conversion Charts

Shoe sizes can vary significantly between different countries and manufacturers, making it crucial to cross-reference and convert sizes to prevent uncomfortable and ill-fitting shoes. This is why it’s a good idea to check shoe size conversion charts wherever possible, especially from international or unfamiliar brands, as it ensures a comfortable and accurate fit. 

We’ve simplified the different widths here:

Men’s Shoe Width Chart

Not all shoe brands offer different widths. In fact, most European brands only come in regular widths. If you have extra wide feet and are buying from a brand that only offers regulars, check out our guide on stretching shoes for wide feet.

A regular or medium width is labeled as a D width, while varying levels of wide fits include E, EE, and EEE widths. On the other side of the spectrum, an extra narrow is a B, and a narrow is a C. This is based on the Brannock device of measurement, which we explain in detail in our guide comparing sneaker fit to dress shoe fit.

Women’s Shoe Width Chart

Just as women’s shoe sizes differ from men’s, so do their widths. Men’s shoe sizes tend to be wider since men’s feet are also wider than women’s. A mens medium is a D, whereas a woman’s is a B, which again is an extra narrow for men.

Women’s width sizes also go far slimmer, offering super slim and slim widths (AAA), in addition to narrow sizes (A).

How to Measure Your Foot Properly

As mentioned, sizes can vary from brand to brand, as well as from country to country. Remember, even sneaker sizes tend to run bigger than dress shoe sizes.

We recommend using a Brannock device, which we break down here again. 

However, you should also know your exact foot measurements as a base reference point. Here’s how to do that:

1. Measure the Ball Width of Your Foot

Take a measuring tape and find the distance between your small toe joint and your big toe joint. This is the widest part of your foot.

The shoe box, or the widest part of the shoe, should be just a little bigger than this measurement, as this is the part of the shoe that locks the foot. It should be a snug but not overly tight fit.

You can also measure your ball girth by taking the measuring tape across the ball and all the way around the joints. The bigger the girth, the bigger the toe box might need to be, or the higher your arches might be.

2. Measure Your Foot Length

Use the measuring tape to find the distance between the end of your heel to the tip of your longest toe. The shoe length should be a bit longer than this, as well. Make sure your toes aren’t touching the front of the shoe.

Especially for loafers, you’ll also want to measure the distance between your heel to the widest part of the ball of your foot. You want to ensure that, with the widest part of your foot locked in the shoe box, there’s little heel slippage with loafers and zero slippage with lace-ups.

If there is slippage, then this portion of the shoe length needs to be shorter (or you can get insoles).

3. Measure Properly and at the Right Time

Ensure you do the following to get the perfect fit:

• Measure your feet wearing the socks you plan on wearing with your shoes
• Measure both feet. You’ll want to go by whichever is the bigger one.
• Take your measurements in the afternoon when they’ve expanded a bit.
