With the help of a friend or family member and a tape measure, you can quickly and easily have accurate measurements taken.
Stand up straight with your arms at your sides. Relax, but stand up straight. Have your friend or family member place the tape measure around the fullest part of your chest under your arms. Have the friend or family member insert a finger between the tape measure and your body to ensure a comfortable fit. This measurement will be your Chest Size. (40, 42, 44, 46, 48, etc).
To determine if you are a "Regular" or a "Long" use the following as a guide to your "Coat Length."
If your height is 5'7" - 6' Your "Coat Length" will be a Regular.
If your height is 6'1" - 6'3" Your "Coat Length" will be a Long.
