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.

Jacket size calculator - where to take measurements?
  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.
  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.
