Men’s Shoe Size Chart: US, UK and EU Sizes by Foot Length

A men’s shoe size chart starts with foot length. Per Nike’s chart, a 10 5/16 inch foot is a US men’s 9 (UK 8, EU 42.5), and an 11 inch foot is a US 11 (UK 10, EU 45). UK sizes run about half a size to a full size below US, but the EU number changes from brand to brand.

There is no single universal men’s shoe size chart. Nike, adidas and Skechers all publish their own, and for the same US size they give EU numbers up to a full size apart. So this guide keeps each brand’s table under its own name instead of blending them into one “standard”. It gives Nike’s foot-length chart in inches, adidas’s chart in centimeters, Skechers’s US/UK/EU conversion and the width letters each brand uses. For every system on one page, including women’s and kids’, start with the shoe size conversion chart.

Men’s shoe size chart by foot length (per Nike)

Nike’s men’s chart is the most complete published table that pairs men’s shoe sizes with foot length. It lists foot length in inches only. Nike says the CM/JP column is a shoe size, not your foot length in centimeters, so don’t measure your foot in cm and match it to that column.

The table above stops at US 18, but Nike’s chart continues in half sizes up to US 22, which it pairs with a 14 11/16 inch foot. Two quirks appear on Nike’s page as published: UK 6 is listed for both US 6.5 and US 7, and the CM/JP value repeats at 23.5 and 24. Those are Nike’s numbers, not typos here.

adidas men’s shoe sizes by foot length in cm

adidas.com blocked automated access during research, so this table comes from the copy published by the retailer evo. The page text was flattened, and the column alignment was rebuilt in row order, so treat it as a close guide and check adidas’s own chart before buying.

The odd-looking EU values are deliberate. adidas uses third-size EU steps, so an EU 42 2/3 is written as 42.7 and 41 1/3 as 41.3. The UK column also sits only half a size below US here (US 10 = UK 9.5), where Nike puts it a full size below (US 10 = UK 9). For the brand’s apparel and kids’ sizing too, see the adidas size chart.

Skechers men’s US, UK and EU conversion

Skechers publishes a conversion without foot length. The table on its size page is unlabeled in the page text; it is read as men’s from its tab order and size range.

Why men’s shoe sizes don’t convert the same everywhere

Put the three charts next to each other and the EU column is where they split. The rows below are copied from the three tables above, not calculated:

A US men’s 10 is an EU 44 at Nike and adidas but an EU 43 at Skechers. A US 9 is 42.5, 42.7 or 42 depending on the brand. The UK gap is steadier: about half a size to one full size below US in all three charts. That is why a “universal” US-to-EU formula doesn’t hold up; the published charts disagree by as much as a full EU size. If you know your size in one brand and are buying another, convert through foot length rather than through the EU number. The Nike size chart covers Nike’s shoes, tops and bottoms if you’re matching across product types.

The CM number printed on a box or tongue label is another trap. Nike states that it is not your foot length in cm. It is a shoe size, and it repeats across neighboring sizes on Nike’s own chart.

How to measure your foot for shoe size

Nike’s at-home method takes two minutes and a second person:

1. Tape a sheet of paper to a hard floor, not carpet.
2. Stand with your feet shoulder-width apart and your weight even, one foot on the paper.
3. Have someone mark the tip of your big toe and the outermost point of your heel, holding the pen straight down.
4. Measure the distance between the two marks.
5. Repeat with the other foot and use the longer measurement.
6. Find that length on the chart. If you fall between sizes, Nike recommends sizing up.

Zappos adds two points: measure while standing, and wear the socks you plan to wear with the shoes. It also notes that any chart is a guide only, because sizing varies by style and manufacturer. A foot measuring device or a soft tape measure makes the reading easier, but a flat ruler works for length.

Sock thickness matters for boots and winter shoes. If you plan to wear thick socks, measure in them; the sock size chart shows how sock sizes map to shoe sizes.

Men’s shoe width chart

Length is half the fit. Width letters are not the same between brands, and they are not the same between men’s and women’s. The standard men’s width is D, while the standard women’s width is B.

Skechers says its “Men’s Wide Fit” equals 2E/3E. Nike describes width differently, as extra room rather than a letter: its Wide fit has about 1/4 inch (6.35 mm) more toe-box girth than regular, and Extra Wide about 1/2 inch (1.27 cm) more.

The Brannock Device you see in shoe stores lists men’s widths from 3A to 3E on its combination model. One caution from a podiatry source: a Brannock width reading reflects the ball of the foot, not the widest point at the toes. If your toes splay wide, a wide toe box can matter more than the letter.

Men’s vs women’s shoe sizes

Men’s and women’s charts use different scales, and the offset depends on the brand. Nike puts US women’s at US men’s plus 1.5. adidas (via evo) and the Brannock formula use plus 1. So a men’s 8 is a women’s 9.5 at Nike and a women’s 9 at adidas. The women’s to men’s shoe size guide covers the conversion in full, and the women’s shoe size chart gives the women’s tables by brand.

Smaller feet can also shop the youth range. Nike’s big-kid Y sizes match US men’s sizes in length, so a 7Y equals a men’s 7. The kids’ shoe size chart lists those sizes with foot lengths.

The verdict

Measure your foot, take the longer foot, and read the chart of the brand you’re buying. Nike’s men’s chart is the best single reference because it pairs every half size with a foot length in inches, from US 3.5 to 22. Use it to find your length-based size, then check adidas or Skechers against their own tables rather than trusting an EU number carried over from another brand. The UK conversion is the most reliable shortcut (roughly half to one size below US), and the EU conversion is the least. Width deserves the same attention: D is standard for men, 2E is wide at both Skechers and New Balance, and Nike measures width as extra toe-box room. When you’re between sizes, Nike’s advice is to size up.
