Men’s International Size Conversion Chart

Finding the right dress shirt or pair of pants can be tricky, especially when shopping online. But the trickiness compounds when you decide to shop online in another country.

You are probably well aware that every country has its own sizing standard and that even sizes between brands can differ. However, asking the retailer to provide exact measurements isn’t just painstakingly long—things can still go awry when your clothes finally arrive at your doorstep!

Calculating European Sizes

Again, different clothing manufacturers follow different sizing standards. However, based on the Dress Shirt Chart above, we can figure out a simple formula to find the correct shirt size for anyone.

The formula is as follows:

Size = Chest Circumference ÷ 2 centimeters

For instance, if the circumference of your chest measures 95 centimeters (37.4 inches), then we can find the correct shirt size by inputting this number into the formula.
