You’re not alone — it’s one of the most common sizing questions and the answer depends on whether you’re buying men’s or women’s shoes. This guide walks you through the exact conversion, how to measure your feet properly, and why size 43 is not always a simple ‘size 9’.

EU 43 men’s UK size: 9 ·

Most common measuring mistake: Taking measure after exercise ·
Average foot length for EU 43: 27.3–27.6 cm

What is a size 43 in the UK?

Men’s UK size for EU 43

• The standard conversion puts EU 43 at UK size 9 for men’s footwear. According to Grivet Outdoors sizing chart, EU 43 maps to UK 9 for men.
• This is backed by Laughing Hens (specialist size conversion resource), which also lists EU 43 as UK 9 for men.

Women’s UK size for EU 43

• For women, EU 43 drops half a size to UK 8.5. Laughing Hens and Calculator.net (conversion tool) both agree on UK 8.5.
• If you see a women’s shoe labelled EU 43, ordering UK 8.5 is your safest bet.

The pattern: one EU size produces two different UK sizes depending on gender. For men, it’s UK 9; for women, UK 8.5. Always confirm the intended gender before checking out.

Is EU 43 UK size 9?

Why some charts show size 10

• Confusion arises because EU 43 also converts to US size 10 for men. Shoppers unfamiliar with US-to-UK differences sometimes misread US 10 as UK 10.
• A few European brands label their EU 43 as UK 9.5, creating further ambiguity. As French-Property.com cross-Channel size guide notes, shoe size conversion is not a precise science and can vary between manufacturers.

How to check brand-specific charts

• Always consult the brand’s own size chart. Nike, Adidas, and Dr. Martens all publish individual conversion tables. Grivet Outdoors recommends comparing your foot measurement in centimetres against the brand’s length chart rather than relying on a generic size label.

The catch: EU 43 is UK 9 for men in standard conversion, but a handful of brands deviate to UK 9.5. Always check the specific brand’s chart before buying.

What are the common mistakes when measuring feet?

Measuring at the end of the day

• Feet swell throughout the day. Measuring right after walking or standing can give a falsely large reading. Podiatrists recommend measuring in the late afternoon when feet are at their natural daily maximum.

Using a ruler vs Brannock device

• A flexible tape or ruler can bend, producing inaccurate length. A Brannock device is the gold standard, but if you don’t have one, place a piece of paper on a hard floor, trace your foot, and measure the straight line from heel to longest toe. Calculator.net offers a digital method that uses the traced length in centimetres.

Forgetting to measure both feet

• Most people have one foot slightly larger than the other. Measure both and buy for the bigger foot. Famous Footwear retailer sizing guidance stresses that ignoring the larger foot leads to pinching and blisters.

Why this matters: the most common sizing errors are easily fixable but frequently overlooked. A few extra minutes of measurement avoids the frustration of returns and the pain of shoes that don’t fit.

What is size 43 in Ireland?

Ireland shoe size system

• Ireland does not have its own shoe size system. Laughing Hens size chart confirms that Ireland uses the same sizing as the UK, meaning EU 43 in Ireland is also UK 9 for men and UK 8.5 for women.

Comparing UK and Ireland sizes

• The UK and Ireland share identical measurement standards for shoes. There is no separate Irish sizing scale. So a shoe labelled “UK 9” in a Dublin store is the same as “UK 9” in London.

The implication: if you’re shopping in Ireland, follow the UK conversion tables exactly. No extra adjustment needed.

Is size 8 the same as 43?

Understanding the EU-UK conversion table

• No — UK size 8 is EU 41, not 43. Laughing Hens lists UK 8 as EU 41 for men and EU 42 for women. EU 43 sits two sizes above UK 8 on the men’s scale and one above on the women’s.

When size 8 UK equals EU 41, not 43

• For men, UK 8 = EU 41. For women, UK 8 = EU 42. The difference between 41 and 43 is about one full UK size. If you’re a UK 8, do not order EU 43 — you’ll end up with a shoe two sizes too large.

The pattern: UK size 8 is two steps below EU 43. Always trace back from your known UK size to the EU equivalent using a reliable chart.

One common conversion table shows the relationship clearly. Let’s look at how EU 43 compares with UK 9, US 10, and approximate foot length.

Three sizes, one pattern: EU 43 sits at UK 9 for men and UK 8.5 for women, while US sizes jump to 10 and 11 respectively.

The trade-off: using a US-centric chart without checking whether it’s US or UK is the number one cause of wrong-size purchases. Always confirm which column you’re reading.

Specifications: foot length and measurement details

Six key measurements clarify exactly what EU 43 means in centimetres and inches.

The pattern: foot length ranges provide a more reliable reference than gender-specific labels.

How to measure your feet correctly (step-by-step)

Follow these five steps to get your true UK size — no more guesswork.

1. Place a piece of paper on a hard floor against a wall.
2. Stand on the paper with your heel touching the wall.
3. Mark the longest toe (not always the big toe) with a pencil held vertically.
4. Measure the distance from the wall edge to the mark in centimetres.
5. Repeat for the other foot and use the larger measurement.
6. Match your cm value to the EU 43 range (27.3–27.6 for men, 26.5–26.8 for women) and confirm the corresponding UK size using Grivet Outdoors sizing chart.

The pattern: a traced length of 27.5 cm means EU 43 / UK 9 for men in most standard systems.

Confirmed facts vs what’s unclear

The implication: rely on foot measurements and brand charts, not assumptions about size numbers.

Expert perspectives on sizing

“Shoe size conversion is not a precise science and can vary between manufacturers. Always try shoes on before buying, or at least check the brand’s own size guide.”

French-Property.com (cross-Channel size guide)

“We always advise customers to measure both feet at the end of the day and use the larger foot as the basis for sizing. Half a size up is better than a shoe that pinches.”

Famous Footwear (retailer sizing guidance)

For UK shoppers, the choice is clear: measure your foot length in centimetres, compare it to the EU 43 range (27–27.9 cm for men, 26.5–27 cm for women), and then use a reliable conversion chart from a source like Calculator.net or Grivet Outdoors. Ignore brand names and go by the numbers — your feet will thank you.
