UK, EU, US Clothing Size Tips

 

• UK baby clothes are primarily labelled by age but think of it as a starting point. You'll see sizes like ‘newborn,’ ‘0-3 months,’ or ‘6-9 months.’ This system is designed for convenience, but since every baby grows at their own pace, it’s best used as a guide. A baby who is larger or smaller than average may need to size up or down accordingly.
  

 

• For babies, weight and height are more accurate than age. While age is a good first glance, a baby's weight can be a much better indicator of a snug and comfortable fit, especially for newborns. This is why European (EU) sizing is so helpful—it's based on the baby's actual height in centimeters. For example, an EU size 62 is designed for a baby up to 62 cm tall, taking the guesswork out of the equation.

 

• Men's sizes work differently, focusing on specific measurements for a precise fit. For tops like t-shirts, hoodies, and jackets, the size is determined by the chest measurement in inches. For bottoms like trousers, joggers, and jeans, you'll see two numbers (e.g., 34W / 32L). The first is the waist measurement in inches (W), and the second is the inseam or leg length in inches (L). This system allows you to get a near-perfect tailored fit right off the rack.

 

• Sizing can differ between brands, so brand loyalty doesn't always equal size loyalty. This is a good rule of thumb for online shopping. A size ‘Large’ from Nike, which often uses a tapered, athletic fit, may feel slimmer than a ‘Large’ from another brand known for a more relaxed, classic cut. Always check the specific size chart on the product page, as this will be your most accurate guide for that particular item.

 

• To convert women’s US sizes to UK sizes, just add 4. This is a simple and reliable rule of thumb. For example, if you are a US size 6, you will be a UK size 10. If you're a US size 8, you'll be a UK size 12. Going the other way is just as easy: simply subtract 4 from the UK size to find the equivalent US size

 

• Alpha sizing’ (S, M, L) is not perfectly standardized, so always check measurements. These letter sizes are convenient, but there is no universal rule for what they represent. One brand might define a ‘Medium’ as a UK 10-12, while another might design their ‘Medium’ to be a firm UK 12. This is why the charts shown are industry averages. Whenever possible, use your actual chest, waist, and hip measurements to find the most accurate fit.

Clothing Size Conversion FAQs

 

What are UK sizes in European?

 

Converting English sizes to European requires a chart because the two systems are measured differently. For women's clothing, you can find the EU size by adding 28 to the UK size (for example, a UK 12 is an EU 40). For men's clothing, the conversion is based on chest measurements, and for children, EU sizes are based on the child's height in centimeters, while UK sizes use age.

 

Are UK and Europe’s sizes the same?

 

No, UK and European sizes are not the same. They use different numbering systems. For instance, a women's size 10 in the UK is an EU size 38, and a men's 38-inch chest (a UK Medium) is an EU size 48. This is why using a conversion chart is essential to ensure you get the correct fit when shopping from different regions.

 

What is size 40 in UK clothes?

 

A European size 40 is equivalent to a UK size 12 in women's clothing. If you're looking for a size 40 in UK men's clothing, this would typically refer to a 40-inch chest measurement, which corresponds to a size Medium (M) or Large (L) depending on the brand and fit.

 

What is size 38 in UK clothes?

 

A European size 38 is a UK size 10 in women's clothing. For men's sizing, a size 38 in UK refers to a chest measurement of 38 inches, which is generally considered a size Medium (M).

 

How do I find my perfect size?

 

Finding your perfect size is a two-step process. First, take your key measurements (chest, waist, and hips) with a measuring tape. Second, compare those numbers to the brand's specific size chart on the product page. Always use the provided chart.

 

How do American and UK clothes sizes work?

 

The main difference in UK US clothing size conventions is found in women's apparel, where US sizes are numerically smaller. The general rule is to add 4 to the US size to get the equivalent UK size (e.g., a US size 8 is a UK size 12). For men's clothing, sizes are more similar as they are often based on chest and waist measurements in inches, but it's still best to consult a conversion chart to be certain.

 

What is size 42 in UK for clothes?

 

A European size 42 is equivalent to a UK size 14 in women's clothes. For men's apparel, a size 42 in UK refers to a 42-inch chest measurement, which typically corresponds to a size Large (L).
