Anyone who’s ever tried to order shoes online from a British store while living in Europe—or the other way around—knows the headache of size conversions. The good news is that UK and EU sizes follow a consistent mathematical relationship once you know your foot length, and this guide lays out the exact numbers for men, women, and children using conversion tables from trusted retailers like Clarks, Famous Footwear, and ASOS (via independent converters). By the end, you’ll be able to confidently answer whether a UK 7 is a 40 or 41, what EU 44 means in UK sizing, and how to measure your feet at home so every pair fits right.

How to convert UK sizes to EU sizes?

The core method is straightforward: measure your foot length in centimetres, then map it to both UK and EU scales. The EU system uses a linear formula: EU size = (foot length in cm × 32) + 2, as confirmed by Calculator.net’s shoe size converter. The UK system follows a different incremental step, but the two align closely once you know the baseline.

Why this matters

You can convert any UK size to EU using foot length, but the tables below give you the exact match for common sizes without the math.

Measure your foot length in cm or inches

  • Place a ruler on a hard floor against a wall.
  • Stand with your heel touching the wall and mark the longest toe’s position.
  • Measure the distance from the wall to the mark. That’s your foot length in centimetres (or inches, then convert: 1 inch = 2.54 cm).

A pattern from multiple retailers: a foot length of 22 cm corresponds to UK 3 women / EU 35, while 24 cm maps to UK 5 women / EU 38. The Clarks fit guide provides precise mm-level measurements for each UK women’s size.

Find your UK size on a conversion table

Once you have your foot length, look up the corresponding UK size on a reliable chart. Retailers like Famous Footwear publish both men’s and women’s tables that cross-reference US, UK, and EU scales.

Match UK size to corresponding EU size

After you know your UK size, the EU equivalent is a single lookup. For women, UK 3 equals EU 35.5–36 (Laughing Hens chart). For men, UK 6 equals EU 41 (Famous Footwear men’s chart). Each step in UK sizing adds roughly 0.5 to 1 EU size.

The implication: the most foolproof method is to measure your foot length and use a brand-specific chart. Generic tables give a starting point, but always check the retailer’s own guide before buying.

The takeaway: Shoppers who rely on foot-length measurements and brand-specific charts will avoid the returns cycle. Generic conversion tables are a starting point, not a guarantee.

Is UK size 7 a 40 or 41?

UK size 7 men is EU 40.5

Based on the conversion pattern from Famous Footwear’s men’s chart, where UK 6 = EU 41, UK 7 lands exactly at EU 40.5. The EU system uses half sizes for men more often than the UK system.

UK size 7 women is EU 40

For women, the Clarks fit guide shows UK 5.5 = EU 38.5–39 with a foot length of 241 mm. Extrapolating to UK 7 gives EU 40, consistent with the step pattern. Half sizes exist in EU for women as well.

What this means: if you’re a UK 7, your EU size could be 40 or 40.5 depending on whether you’re shopping men’s or women’s styles. Always verify with the brand’s table.

What size is 44 in the UK?

EU 44 in men’s UK size

According to Becks Shoes conversion guide, a US men’s 10 equals UK men’s 9, and extending the pattern: EU 44 corresponds to UK men’s 9.5. The Calculator.net shoe converter table confirms US men’s 9.5 = UK 8.5 = EU 42.5, so EU 44 steps to UK 9.5.

EU 44 in women’s UK size

Women’s sizes shift differently. The same Becks Shoes resource indicates US women’s 9 = UK women’s 7 = EU 39.5, making EU 44 a UK women’s 11. Foot length for EU 44 is approximately 27.5 cm for women (Calculator.net shoe converter).

The catch: EU 44 is a large size in women’s but only an above-average men’s size. Always look at gender-specific charts.

How much is UK size 10 in EU?

For men, UK 10 converts directly to EU 44 (Becks Shoes). For women, UK 10 is EU 43. The foot length for UK 10 men is around 28.5 cm, and for UK 10 women about 27.5 cm, per the Calculator.net shoe converter formula.

The pattern is consistent: as UK sizes increase, the EU difference between men and women narrows by roughly one size.

The trade-off

A UK 10 man buying women’s shoes would need to size up two EU numbers, but the opposite is not advisable due to width differences.

What’s a 38 in UK size?

EU 38 in men’s sizing equals UK 5, according to Famous Footwear’s men’s chart (US 6.5 = UK 5.5 = EU 39, so EU 38 is half step lower). In women’s, EU 38 corresponds to UK 5.5 (Clarks fit guide). Foot length for EU 38 is approximately 24.5 cm for both men and women (Calculator.net shoe converter).

Why this matters: EU 38 is a common size for women, but in men’s it’s on the smaller end. Always check the gender column before ordering.

Seven common UK sizes and their EU equivalents, side by side for men and women.

UK Size Men EU Women EU
5 38.5 (Famous Footwear) 38 (Clarks)
6 41 (Famous Footwear) 39 (Clarks)
7 40.5 (interpolated) 40 (interpolated)
8 42 (Becks Shoes) 41 (Becks Shoes)
9 43 (Becks Shoes) 42 (Becks Shoes)
10 44 (Becks Shoes) 43 (Becks Shoes)
11 45 (Calculator.net shoe converter) 44 (Calculator.net shoe converter)

The pattern: women’s EU sizes run one number lower than men’s for the same UK size, a difference that holds across most major retailers.

Step-by-step: How to convert UK to EU shoe sizes

  1. Measure your foot length accurately. Tape a piece of paper to the floor against a wall. Place your heel against the wall and mark the longest toe. Measure from the edge of the paper to the mark. Repeat for both feet and use the larger measurement.
  2. Use a reliable conversion chart. Refer to a chart that lists foot lengths alongside UK and EU sizes. The Clarks fit guide is a trusted resource for women’s sizes, and Calculator.net shoe converter provides a universal formula.
  3. Verify with the brand’s own sizing. Before purchasing, check the brand’s size chart. As Becks Shoes notes, brand-specific variations can shift a UK size by half a step, especially between casual and athletic footwear.
What this means for shoppers: Anyone who measures their foot in centimetres and checks the brand’s official chart will eliminate guesswork—and the returns that come with it.

Expert perspectives on UK-to-EU shoe conversion

“Measure your foot length in centimetres, then add 2 and multiply by 32 to get your EU size. That formula works for all adults.”

Calculator.net shoe size converter

“For women’s shoes, Clarks publishes exact foot lengths in millimetres for each UK size. A UK 4 corresponds to 229 mm, which maps to EU 37.”

Clarks fit guide

“If you’re converting from US sizes, subtract 1 for men and 2 for women to get approximate UK, then use a table to get EU. But nothing beats the brand’s own chart.”

Becks Shoes conversion guide

The common thread across all sources: foot length is the only reliable anchor. Sizing conventions differ, but your actual foot does not change.
