Things to Consider When Choosing the Right Size:


It is best to use the MLB jersey size chart as an initial basis for your choice of size. The sizes may be based on the shirt sizes you usually get for your other shirts. However, remember that baseball jerseys are not made to be a snug fit to your body.

If you want a more precise way to know your jersey size, then it is time to measure your bust, waist, hips, sleeves, and neck using a measuring tape.

  1. Your bust size is the span from your shoulder to shoulder, going over the fullest portion of your chest.
  2. The waist is the narrowest portion of your torso, just around the area where you normally wear your pants. Place the measuring tape over your natural waistline, but keep it slightly loose.
  3. Hips, on the other hand, are the fullest part of your torso. Like taking your waist circumference, keep your measuring tape loosely around the hips.
  4. Sleeves and the neck may be taken with an assist. The sleeve length is taken from your nape down to your wrist. Then, the neck is measured around your neck up to its base.

Aside from these measurements, consider the possible layers you will wear underneath your jersey. If you wear undershirts or arm warmers, it is recommended to go the next size for a comfy fit.
