How International Clothing Sizes Work
Clothing sizes vary significantly between countries and even between brands within the same country. The US uses letter sizes (S, M, L) or numeric sizes for most garments. The UK uses even numbers starting from 4. European sizes use a different numeric scale based on body measurements in centimeters. Australian sizes closely follow the UK system, while Japanese sizes tend to run smaller than Western equivalents. Understanding these differences is essential when shopping internationally or online from foreign retailers.
How to Measure Yourself
Chest/Bust: Measure around the fullest part of your chest, keeping the tape level and snug but not tight.
Waist: Measure around your natural waistline (the narrowest point), typically just above the belly button.
Hips: Measure around the fullest part of your hips, usually about 8 inches below your waist.
Inseam: Measure from the crotch seam to the bottom of the leg on a well-fitting pair of pants.
Tip: Use a flexible measuring tape and stand naturally. Have someone else measure you for best accuracy.

Frequently Asked Questions
Why do clothing sizes vary between brands?
There is no universal standard for clothing sizes. Each brand creates its own size chart based on their target customer. "Vanity sizing" — where brands label clothes with smaller numbers to flatter customers — has also caused size inflation over the decades.
What is the difference between US and UK sizing?
For women, UK sizes are typically 4 numbers higher than US sizes (US 6 = UK 10). For men's letter sizes (S, M, L), they are generally the same. For men's pants, US and UK waist sizes in inches are identical.
How do European sizes work?
European sizes are based on body measurements in centimeters. For tops, the EU size roughly equals half the chest measurement in cm. For example, a 96cm chest corresponds to EU size 48. Italian and French sizes may differ slightly from standard EU sizing.
Do Japanese sizes run smaller?
Yes. Japanese clothing sizes generally run 1-2 sizes smaller than Western equivalents. A US Medium often corresponds to a Japanese L or XL. Always check specific measurements rather than relying on size labels when buying Japanese brands.
What if I am between two sizes?
If you fall between sizes, consider the garment type and desired fit. For structured items like blazers, size up. For stretchy or relaxed-fit items, either size may work. When in doubt, check the brand's specific size guide and return policy.
Are Australian and UK sizes the same?
Australian sizes are very similar to UK sizes for most garments. However, some Australian brands have adopted their own sizing that may differ slightly. Always verify with the specific brand's size chart.
