Here is a guide on how to measure your size for men 's clothing. To get the right size, measure carefully, and update your measurements regularly.
When you have your correct measurements, you can easily find your US size.
Use a tape measure and the help of a friend to take the following measurements:
Use the tape to measure around the base of your neck, where it meets your shoulders. Put a finger between your neck and the tape measure for a more loose fit collar.
Bend your elbow and put your hand on your hip. Ask your friend to measure from middle of back of your neck, around shoulder and elbow to wrist bone.
The measurement should be taken beneath your armpits, around the widest part of your chest and shoulder blades. Keep the tape measure horizontal.
Put the tape around your natural waistline, which should be close to your bellybutton. Put one finger between the tape and your body before you measure.
This is measured between your groin and your lower ankle. You might find that is most easily measured on a pair of pants that already suit you.
