How To Measure

Neck: Place measuring tape wrap around the nack joining under Adam's apple;

Shoulder: Measure between the under-colla seam and the sleeve seam;

Waist: Measure precisely;

Chest: Keep measuring tape horizontal, wrap around the biggest girth of the chest, keeping the measuring tape up and close to the arm pits;

Sleeve length: Have the man that you are measuring stand still, with his arms falling naturally to his sides,
Begin at the middle of the upper back, as shown in the picture to the right,
Measure the length from the middle of the upper back to the stitching located at the shoulder of the shirt. Remember this value,
Measure the length from the top stitching on the shoulder to the bottom of the wrist. Be careful not to measure too high above the wrist, or the dress shirt's sleeves will come out to be too short,
Add these two values together to determine your sleeve length. The value should range anywhere from about 32 - 37 inches;

Back length: Measure from the collar edge to the wanted length.
