    • If you need a women's jacket, put in your chest and hip measurements.

How to measure jacket size?

Taking jacket measurements is as easy as pie! For comfort's sake, you might want to ask another person to assist you, but you should be able to do it on your own without any trouble. One thing to remember is don't take measurements over your regular clothes. In order for them to be accurate, you need to take the measurements close to your body.

You will find instructions on how to measure jacket size below.

  1. Chest measurement
    • To find out your chest width, take a measuring tape and wrap in under your armpits, at the fullest part of the chest. Do not puff out your chest. Stand up straight and relax. Remember to leave a little space to move around, but do not overdo it. It should be no more than an inch (or about 2.5 centimeters - refer to our length converter if you need other units).
    • The procedure is the same for women. Remember to take the measurement on the widest part of your breasts. While you're at it, consider killing as many as three birds with one stone by using this measurement to calculate your bra and bikini size!
  2. Hips measurement
    • To take this measurement, wrap a measuring tape around your hips at the widest part of your buttocks. Put your feet together while taking the measurement for maximum precision.

What's my size in Europe? Jacket size charts

Unfortunately, there is no unified sizing system around the globe. Luckily, in the case of coat size it's not nearly as complicated as with shoe sizes, and most clothes producers around the world conform to either the US or the European sizing system - you will find these two in our jacket size calculator.

If you're interested in the precise jacket size measurements hiding behind the letters, or you're looking for a quick jacket size converter, check out the two jacket size charts below:
