Men's International Size Conversion Chart

Men's international sizes at a glance#

Men's international clothing sizes match a US suit jacket or coat size to its UK, European, Japanese and alpha (S, M, L) equivalents. On this page a US 38 jacket is a UK 38, a European 48 and a Japanese 40, and reads as a medium. UK numbers match US numbers, and the European size runs 10 higher in jackets.

In jacket and coat sizes a European 46 is a US 36, a 48 is a US 38, a 50 is a US 40, a 52 is a US 42, a 54 is a US 44 and a 56 is a US 46. European here covers French, German, Italian, Spanish and most other EU labels, and UK sizes read the same as US. Pants follow a separate scale: a European pant size runs 16 higher than the US waist in inches, so an EU 50 pant is a US 34 (a 34 inch / 86 cm waist).

These conversions are compiled from this page's own jacket, pants and dress shirt charts and cross-checked across the US, UK, European, Russian, Japanese and Korean columns. Cut still varies by brand, so measure your chest for jackets and your waist for pants and check the brand's own chart where you can. For trousers and jeans see the pants size chart for men and women, and for footwear the international shoe size conversion chart and shoe size recommender.

FAQ on men's international size conversion chart#

How do I accurately use the men's international size conversion chart for jackets and coats?#

To accurately use the chart for jackets and coats, first, determine your US jacket or coat size by measuring your chest width, shoulder width, and sleeve length. Once you have your US size, refer to the chart to find your equivalent size in the UK, Europe, Russia, Japan, Korea, and S-M-L categories. For instance, if your US size is 38, you would look at the corresponding sizes: UK 38, Europe 48, Russia 48, Japan 40, Korea 100, and M in S-M-L. Remember, the fit can vary by brand, so always check the brand’s specific size chart when possible.

How can I convert my pants size for international shopping, especially between American and European systems?#

To convert your pants size between the American and European sizing systems, find your US pants size based on your waist measurement in inches. Then, use the chart to identify the corresponding European size. For example, a US pants size of 32 translates to a European size of 48. Note that European sizes cover a range of countries with slight variations, so consider this a general guide and consult the specific brand's sizing chart for the best fit.

What is a US jeans size in EU?#

Men's jeans use the same numbers as the pants chart above: the waist in inches. Add 16 for the European size, so US 30 jeans are an EU 46, US 32 an EU 48, and US 34 an EU 50. The pants size chart for men and women maps each size to its waist measurement.

What is a 32, 34 or 36 inch waist in European sizes?#

A US men's pant size is the waist in inches, so a 32 inch waist (81 cm) is an EU 48, a 34 inch waist (86 cm) an EU 50, and a 36 inch waist (91 cm) an EU 52. The full mapping is in the pants chart above.

How do European sizes convert to UK sizes?#

UK men's sizes are the same as US sizes; the jacket chart above lists US 38 and UK 38 in the same row. So subtract 10 from a European jacket or coat size to get the UK size (EU 50 = UK 40), and subtract 16 from a European trouser size (EU 50 = UK 34). UK trousers and jeans use the waist in inches, just like the US.

What should I know about converting dress shirt sizes between American, English, and European systems?#

When converting dress shirt sizes, it’s important to understand that American sizes typically include two numbers: neck size and sleeve length, both in inches. European (including English) sizes, however, generally use one number for the neck size and might have a standard sleeve length. To convert, match your American neck size to the closest European neck size. For example, a 15.5” neck size in the US approximately corresponds to a 39 in Europe. Keep in mind, sleeve length might need separate consideration if the brand specifies different lengths.

What is a size 14 in European sizes?#

On this men's chart, 14 is a dress shirt size: a US 14 collar (a 14 inch / 35.5 cm neck) is a European 36. If you mean the women's US dress size 14, that is an EU 44 to 46 depending on the brand's cut; the international dress size conversion chart maps it with the matching bust, waist and hip measurements.

Are there differences in sizing for trousers and dress shirts within the European size system?#

Yes, within the European size system, there can be differences in sizing conventions for trousers and dress shirts. Trousers in Europe are typically sized based on waist measurements in centimeters, while dress shirts focus on the neck circumference. This difference means you may need to convert and compare sizes separately for trousers and dress shirts when shopping across European countries.

How do I ensure the best fit when sizes vary between brands?#

Since sizes can vary significantly between brands, the best strategy is to take precise body measurements (chest, waist, hips for jackets and trousers; neck and sleeve for dress shirts) and compare these to the specific brand’s size chart. Many brands also provide fit guides or model measurements for reference. When possible, try on clothes before purchasing, especially from international brands, to ensure the best fit. Reading customer reviews can also offer insights into how true to size a brand's clothing is.

Can I rely on the international conversion chart for purchasing accessories like belts or shoes?#

The international conversion chart provided focuses on clothing items like jackets, trousers, and dress shirts. For accessories like belts or shoes, you would need to refer to specific conversion charts for those items. Belt sizes often correlate with waist sizes but can vary by brand, while shoe sizes have their own conversion system entirely different from clothing sizes; see the international shoe size conversion chart.

What is a European or Italian size 42 or 44 in US sizes?#

Italian sizes follow the European column in the charts above. In suit jackets and coats, an EU or IT 42 is a US 32 (an XS) and an EU 44 is a US 34 (a small). In pants, European sizes run 16 above US, so a 44 would be roughly a US 28 waist, below the range of the pants chart. Check which garment the label belongs to before converting.

What is size 42 in US men's clothing?#

Size 42 in US men's clothing typically refers to jacket or coat sizes. To convert this size to other international sizes, refer to the conversion chart provided. For example, a US size 42 corresponds to a UK size 42, European size 52, Russian size 52, Japanese size 44, Korean size 110, and is generally considered a large (L) in the S-M-L sizing system.

How do I find the men's size 42 in US jackets or suits?#

To find the men's size 42 in US jackets or suits, measure your chest width, shoulder width, and sleeve length. Once you have your measurements, you can use the conversion chart to find the corresponding sizes in other international systems. For a US size 42, the equivalent sizes would be UK 42, European 52, Russian 52, Japanese 44, Korean 110, and large (L) in S-M-L.

What does 42 regular suit size mean in men's clothing?#

A 42 regular suit size in men's clothing means the jacket has a chest measurement of 42 inches, and the length of the jacket is regular, suitable for someone of average height. The waist measurement of the trousers that come with the suit is usually about 6 inches less than the jacket size, so it would be around 36 inches for a 42 regular suit.

Where can I find regular 36 size jeans men's 34 in inseam for sale?#

What advice do you have for shopping internationally online to avoid size mismatches?#

When shopping internationally online:

• Always start with your current measurements rather than relying on your usual size.
• Look for size conversion tools or charts on the retailer’s website.
• Read product descriptions for notes on fit (e.g., slim fit, true to size) and sizing tips.
• Check return policies in case the fit isn’t right, considering that international returns can be more complicated.
• Utilize customer service by asking for specific item measurements or additional sizing advice if you're unsure.

Start from your own measurements, convert with the charts above, and check the brand's chart when one is available. That gets the size right far more often than guessing from your usual US size.
