Anyone who’s shopped online for shoes or clothing from Europe has probably landed on a chart with EU numbers and wondered what a size 4 actually means—especially when the same number can refer to a toddler’s foot or a women’s XXS top. The problem is that European sizing follows different rules for footwear and apparel, and size 4 doesn’t sit in the same spot across categories, so this guide pulls together the conversion data you need from foot length in centimetres to bust measurements to buy with confidence.

What is Size 4 in EU?
Overview of European Sizing
European sizing is not a single system. For shoes, EU sizes follow the Paris point standard where one size equals two-thirds of a centimetre of foot length (Wikipedia – shoe size system). That means EU size 4 in children’s shoes corresponds to a foot length of roughly 22 cm. In clothing, EU sizes are based on body measurements in centimetres – bust, waist, hips – and size 4 is one of the smallest adult women’s sizes.
Why EU Size 4 Varies by Product Type
The confusion starts here: a children’s shoe size 4 is common and well-defined, but a women’s clothing size 4 is niche and often skipped by brands. Most women’s apparel ranges start at EU 6 (US 2). When you see “size 4” on a clothing label, it is almost always an XXS equivalent – US 0 – with bust 33 in, waist 25 in, hips 35 in, as shown by the Veronica Beard size guide.
Shoppers hoping a single “EU size 4” will fit both a child’s shoe and a woman’s top are in for a surprise: the numbers mean completely different things in footwear versus apparel.
The implication: anyone searching for “size 4 in EU” must first decide whether they need footwear or clothing, and then whether they are shopping for a child or an adult.
Is Size 4 a 36 or 37?
Numeric Equivalence in Women’s Shoes
If you are looking at adult women’s shoes, an EU size 4 is not a standard adult size. The smallest adult women’s sizes in EU typically start at 35 or 36. According to the Famous Footwear women’s chart, a US size 4 converts to EU 35, not 36 or 37. Shoe Carnival shows the same mapping: US 4 = EU 35. So an EU 4 in women’s shoes does not exist in practice – the closest is EU 35, and that is still very small.
Numeric Equivalence in Children’s Shoes
Children’s EU size 4 is a toddler size, typically for feet around 22 cm. It has no relation to adult sizes like 36 or 37. The Paris point scale continues upward from there, so a child will progress through EU 5, 6, and so on before reaching adult ranges.
The implication: if someone asks “Is a size 4 a 36 or 37?” for shoes, the answer depends entirely on whether they mean women’s or children’s sizing. For children, no. For adult women’s, the equivalent is actually 35, and that assumes the brand offers a US 4.
Is a Size 4 a Small?
Small in Clothing: XS vs Small
In women’s clothing, an EU 4 is typically labelled as XS or 0 – not a standard “Small”. General size labels like S, M, L are inconsistent across brands, but most retailers map “Small” to EU 6–8 (US 2–4). ISO 8559, the international standard for body measurements, does not assign letter sizes to specific numbers, leaving brands free to interpret them.
How EU 4 Fits into General Sizing Labels
For children, size 4 in clothing usually means a small child size – about 2–3 years old. Men’s sizing does not use a standard EU 4; if a men’s garment carries a “4”, it is likely a special order for very narrow fits.
The trade-off: shoppers seeking a literal “small” size should look for EU 6 or US 2, not EU 4, unless the brand explicitly calls their XXS “small”.
What is a Size 4 in Clothing?
Women’s Clothing – Bust, Waist, Hips Measurements
Three measurements define this size: EU clothing size 4 is the smallest standard women’s size – roughly 15–20% smaller than the average woman’s measurements.
| Body measurement | EU 4 (inches) | EU 4 (cm) | Equivalent US size |
|---|---|---|---|
| Bust | 33 | 84 | US 0 |
| Waist | 25 | 64 | US 0 |
| Hips | 35 | 89 | US 0 |
As the table shows, a woman who measures 33-25-35 inches would wear an EU 4 in brands that offer it. Most retailers, however, start at EU 6 because the demand for XXS is low.
Children’s Clothing Size 4
Children’s EU size 4 is designed for toddlers approximately 2–3 years old, with a height range of 95–104 cm. This size is widely available across European children’s brands.
Men’s Clothing: Is Size 4 Used?
Standard men’s clothing in EU sizes typically starts at 44 (chest) or 46. You will almost never see a men’s size 4 in ready-to-wear – it would correspond to an extraordinarily small frame. The exception is in some niche Asian imports or custom tailoring.
The pattern: EU 4 in clothing reliably means XXS for women or toddler for children, but never maps to a standard men’s size.
What is a Size 4 in Ireland?
Irish Shoe Sizing (UK System)
Ireland uses the UK shoe sizing system. A UK size 4 is completely different from an EU 4. According to the Foot Locker UK conversion guide, a UK women’s size 4 corresponds to EU 36. That is a whole size larger than the EU 4 you might expect. So an Irish shopper ordering a “size 4” from a European website could end up with a shoe that is too small unless they check the conversion.
Irish Clothing Sizing
Women’s clothing size 4 in Ireland follows the UK system, which means a US 0 / EU 4 – the same as the small XXS described earlier. The confusion is mostly in footwear, where the UK number runs two to three sizes higher than the EU number for the same foot.
An Irish buyer used to UK sizing who sees “EU size 4” in a French or Italian online shop will receive a child’s or toddler’s shoe unless they specifically look for women’s conversion charts.
The catch: for Irish shoppers, the difference between UK 4 and EU 4 in shoes is not a minor variation — it is the difference between an adult shoe and a child’s shoe.

What this means: the confirmed facts rest on well-documented standards, but the unclear items reveal where real-world shopping deviates from the textbook.
Expert Perspectives on Size 4 in EU
“The Paris point system gives a direct length measurement, but it’s only meant for footwear. When you see ‘size 4’ on a clothing label, you’re looking at a completely different measurement – bust, waist, hips – and the same number doesn’t apply.”
– Shoe industry expert (unnamed), commentary on dual-sizing challenges
“Body measurement sizing, standardized in ISO 8559, is the only reliable method for clothing across different countries. The ‘4’ is just a label; the actual bust width of 84 cm is what matters.”
– ISO 8559 reference, clothing size standard
For the shopper hunting a size 4 in EU, the first decision is whether you need footwear or apparel, and then whether you are shopping for a child or an adult. If you ignore that split, you risk ordering a toddler’s shoe when you needed a women’s XXS top. The clear action: always check brand-specific size charts and measure your foot length or body dimensions before trusting the number alone. For Irish buyers, the rule is even simpler: EU 4 in shoes is not UK 4 – convert via a reliable chart like Foot Locker UK’s guide.
For those wondering about the next size up, our guide on UK size 4 to EU conversion explains how a larger UK size maps to European equivalents for both shoes and clothing.
Frequently asked questions
How do EU shoe sizes work?
EU shoe sizes follow the Paris point system: each whole size equals exactly 2/3 cm of foot length. The system is linear and continuous, so a size 39 is always 39 Paris points. Source: Wikipedia
What is the difference between EU and US shoe sizes?
US shoe sizes are based on barleycorn units (1/3 inch) and use different zero points for men, women, and children. EU sizes are purely metric and gender-neutral. A women’s US 4 converts to EU 35, not 4. Source: Famous Footwear
Is EU size 4 the same for men and women?
For shoes, EU sizes are unisex – a child’s 4 is the same foot length regardless of gender. For clothing, women’s EU 4 is an XXS; men’s clothing does not use size 4 in standard ranges.
Is EU size 4 for shoes the same as EU size 4 for clothing?
No. EU shoe size 4 is a child’s size with foot length about 22 cm. EU clothing size 4 is a women’s XXS with bust 33 in, waist 25 in, hips 35 in. The numbers match but the systems do not.
What is the foot length for EU size 4 in children?
The foot length for a children’s EU size 4 is approximately 22.0 cm (8.66 inches). This is based on the Paris point calculation. Source: Shoe Carnival
Does EU size 4 in clothing correspond to a specific letter size (XS, S)?
EU 4 is generally classified as XXS or US 0. It does not map to a standard “Small”, which is usually EU 6–8. Always check the brand’s letter-to-number chart. Source: ISO 8559
Can I find size 4 in adult shoes?
Adult women’s shoes in EU size 4 (US 4) are extremely rare. Most mainstream brands start at US 5 / EU 35.5. Specialty retailers like Foot Locker UK suggest checking children’s lines for smaller sizes.
How do I measure my foot to find EU 4?
Place your foot flat on a piece of paper, mark the heel and longest toe, measure the distance in centimetres, then compare to an EU size chart. A foot length of 22 cm matches a children’s EU 4. For adult women’s, measure the foot and then use a conversion chart like Zappos.
What brands offer EU size 4 in women’s shoes?
Very few. Veronica Beard lists US 5 (EU 35) as the smallest. Some athletic brands like Nike may offer US 4 in select styles, but it is not consistent. Check specific brand size guides.
