The entire Europ, however, has a different standard of sizes in both clothing and footwear. For children, UK sizes are mainly based on the height and other measurements, not age.

For example, if a woman buys a jersey top in size 6 (or small) in US sizing, she might have to buy a size 10 in UK. But when she buys shoes, she will have to choose a smaller size than her normal US size. Confusing right? As far as men’s clothing is concerned both UK and US sizes are almost the same.

How to Measure Your UK Size

Before trying to convert your sizes to UK sizing standards, it is a must to find out your most accurate measurement first. You might have an idea of what your size is, but making sure your size is correct will save you tons. Most people who think they are wearing the right size are often mistaken. Many usually get a larger size, while some mistakenly go for a smaller size.

You might want to get yourself measured with a tape in order to find your correct size. Then use a conversion chart to find your UK sizes.

In order to find out your correct size you might need the measurement of the circumference of your chest or breast (if you are a woman). This is measured in inches by wrapping the tape measure around the widest part of your chest/breast. This measurement will typically be useful for jackets, suits, tops and shirts.

Another important measurement is your neck size. Simply wrap the tape measure around your neck, and add an extra half inch to the number to get the measurement fast.

The measurement of your waist and the length of the legs are needed to figure out the size of your jeans and trousers. This can be done by wrapping a tape measure around the waist at the navel. For women, these measurements are taken at the widest part of the hips.

Knowing these measurements and converting them to find out your US sizes will be very helpful once you start shopping. Once you know your correct US size, it is also easier to find out your international sizes including UK’s.

Remember: In UK sizes are usually measured in centimeters rather than in inches, which is common in US.

Things to Remember About UK Sizes

  • When converting the US size to UK size, rules are different for men, women and children, especially when it comes to clothing.
  • Women have to go for bigger sizes for clothing, but smaller sizes for shoes.
  • Men can buy the same size of clothes they buy in usual US sizing. But they will have to consider smaller sizes of shoes using the UK standard.
  • For kids, the size differences in clothing are not very noticeable up to certain ages. But rules change depending on the gender if the kid is above 10 years older as certain measurements like chest (for girls) tend to be more prominent than guys.
  • All the size charts and conversion techniques can help you find the ideal size. But trying out the clothes and shoes before buying them is still the best way to find the perfect fit. Different manufacturers after all, uses different sizing standards.

Tips When Buying in UK Sizes

For clothes :

  • If you are a woman go for higher size than your US size when buying clothes. If you are a US 4, in UK size, you will be a UK 8.
  • If you are a man, go for the same size when buying clothes. For example, a size US 30-32 is the same as a UK 30-32.
  • If you are buying clothes for your kids less than 8 years old, the US size would be almost similar in UK sizes.
  • If your kid is older than eight years old, go for one size lesser than the US size. Sizes by this time will also be different for boys and girls.

For Shoes:

  • If you are woman looking for shoes, make sure you choose a smaller UK size than your US size. For example, if you are a US 4, in UK size, you will be a UK 2.
  • If you are buying shoes for men, you might have to also choose smaller size than your usual US size by .5 or by using conversion charts. If you are a US 6.5, buy a UK 6.
  • For kids shoes, UK sizes are also generally smaller than US standard sizes.
