Global Size Chart

A "size 9" can mean something completely different depending on where you're shopping — and it's not just shoes. Whether you're eyeing Italian boots, Japanese streetwear, or a UK-cut jacket, the numbers rarely line up. This tool converts shoe and clothing sizes between US, UK, EU, Japan, and China, right down to the centimeter.

How to Measure Shoe Size Accurately at Home

Finding your correct international shoe size starts with one simple rule: measure your feet in centimeters (CM). Size labels like US, EU, or UK vary between brands, but actual foot length remains consistent worldwide.

Step-by-Step Foot Measurement Guide

  1. Place a sheet of paper against a wall on a hard floor.
  2. Stand with your heel touching the wall.
  3. Keep your weight evenly distributed.
  4. Mark the tip of your longest toe.
  5. Measure the distance from the wall to the mark in centimeters.
  6. Repeat with the other foot — use the longer measurement.

Once you have your measurement, use our 👉 international shoe size converter to find equivalent sizes across regions.

Why Centimeters Are the Most Reliable Measurement

  • CM measurements are consistent worldwide.
  • Shoe size numbers differ between countries.
  • Brands frequently adjust sizing standards.
  • CM helps eliminate guesswork when shopping online.

Common Shoe Measurement Mistakes

  • Measuring in the morning (feet expand during the day)
  • Wearing thick socks unintentionally
  • Ignoring foot width
  • Assuming both feet are identical

Width Matters Too

Some brands offer:

  • Narrow (N)
  • Regular (M)
  • Wide (W)

If you fall between sizes, consider trying a half size up.

How to Measure Clothing Size Correctly

To buy clothes that fit—especially from international brands—you need reliable body measurements. This guide covers what to measure, what to use, and how to avoid common errors. Once you have your numbers, use our clothing size converter to see your equivalent size in US, UK, EU, and other regions.

Tools You Need

  • Soft measuring tape. A cloth or plastic tape that wraps around the body is best. Avoid a stiff metal ruler for chest, waist, and hips.
  • Flat surface and mirror (optional). Stand on a hard floor. A mirror helps you check that the tape is level and not twisted.
  • Light, close-fitting layers. Measure over undergarments or one thin layer. Bulky clothes will make your measurements too large.

How to Measure Properly: Posture and Clothing

Stand in a relaxed way: feet slightly apart, arms at your sides. Do not suck in your stomach or stand extra straight. Breathe normally when you take the measurement. The tape should sit snug against your body but not dig in. If the tape leaves a mark or feels tight, it’s too tight. If it slides down, it’s too loose.

Chest Measurement

For tops, jackets, and dresses, measure your chest at the fullest point. For most people this is at or just below nipple level. Wrap the tape around your chest, under your arms, and keep it parallel to the floor. The tape should be snug but not tight—you should be able to take a normal breath. Record the number in centimeters or inches.

Waist Measurement

Your natural waist is the narrowest part of your torso, usually 1–2 inches above your belly button. To find it, bend to the side; the crease that forms is your waist. Wrap the tape around your waist and keep it level. For pants that sit on your hips, also measure where you usually wear the waistband; that may be lower than your natural waist.

Hips Measurement

Stand with your feet together. Wrap the tape around the fullest part of your hips and bottom—often about 7–9 inches below your waist. Keep the tape parallel to the floor. This measurement is used for pants, skirts, and fitted dresses.

Inseam Measurement

Inseam is the length from your crotch to where you want the hem to sit (e.g. ankle or floor). Easiest method: take a pair of pants that fit the way you like and measure from the crotch seam to the bottom of the leg. Or have someone measure from your crotch to your ankle bone (or desired length) while you stand straight. Record in inches or centimeters.

Sleeve Length

For shirts and jackets, sleeve length helps get the right fit. Start at the center of the back of your neck, run the tape over your shoulder and down the outside of your arm to your wrist (or to where you want the cuff to sit). Keep your arm slightly bent. This gives a “center-back to cuff” measurement that many size charts use.

Differences for Men, Women, and Kids

Men’s sizing usually focuses on chest and waist; shirts may use neck and sleeve. Women’s sizing often uses bust, waist, and hip, and the same size number can mean different things in different countries. Kids’ sizes are often based on age or height (e.g. 110 cm, 120 cm). When you use our clothing size converter, choose the right category (Men, Women, Kids) and garment type (tops, pants, dresses) for accurate results.

Common Measurement Mistakes

  • Too tight tape: The tape should rest on your skin without compressing it. Indentations mean the measurement is too small.
  • Wrong posture: Stand normally. Sucking in or standing unnaturally leads to numbers that don’t match how you’ll wear the clothes.
  • Measuring over bulky clothing: Measure over one thin layer or undergarments only.
  • Tilted tape: Keep the tape level all the way around. A slant gives a larger measurement than your true size.
  • Guessing instead of measuring: Don’t assume your size in a new brand or region. Measure or use the brand’s size chart.

Why Size Labels Differ Across Brands

There is no single global standard. Brands use different fit models and design goals. Some use “vanity sizing” (smaller size labels for the same measurements). Others run true to size or small. After converting your measurements with our clothing size converter, always check the brand’s own size chart when you can.

Fit Types

Why sizes don't always line up

Sizing differences aren't random — they come from history, manufacturing, and culture, and understanding them makes conversion easier to trust.

Regional systems grew up separately

Each region developed its sizing system independently based on local manufacturing standards and average body measurements. The US system evolved from English measurements but diverged over time; the EU adopted metric-based sizing in the 1970s; UK sizing kept closer ties to historical English measurements; Asian systems developed separately around different average body proportions. Asian sizing tends to run smaller than Western equivalents as a result.

Brands add their own variation on top

Even within one region, brands use different sizing charts, fabric stretch, and design intent — European brands often lean slimmer, US brands tend to run more relaxed, and "vanity sizing" (labeling clothes smaller than the actual measurements) is common in US women's wear. That's why the same label can fit differently from one brand to the next.

Centimeters are the one constant

Metric (EU, Asia) and imperial (US, UK) systems don't convert perfectly because the underlying measurement standards differ. A centimeter-based measurement is the one reference that means the same thing everywhere, which is why it's the most reliable anchor for a conversion.

Frequently Asked Questions

What is EU shoe size 42 in US?

An EU 42 typically converts to a US men's size 8.5–9, but sizing varies between brands. Use our shoe size converter for accurate comparisons.

Why do sizes differ between countries?

Sizing systems were developed independently, using different measurement models and manufacturing standards.

How accurate is CM measurement?

Centimeter measurements are the most reliable method because they represent the actual physical length of your foot or body.

Are clothing sizes universal?

No. Clothing sizes vary significantly across regions and brands, even when labeled the same.

Why does my size change by brand?

Brands use different sizing charts and fits. Factors include fabric stretch, target audience, and regional manufacturing norms.
