Size by Height and Weight

Weight is the primary guide for shirt sizing. Men with the same weight but different heights typically wear the same size. Regular Fit is our classic everyday cut, with a comfortable shape through the chest and waist.

About our sizing

Regular Fit Shirts are our classic everyday cut, with a balanced shape through the chest and waist. The chest and waist are shown as half measurements, so double them for the full circumference. Neck size matters most for dress shirts worn buttoned up; if your neck size sits between two recommended sizes, choose the larger one for collar comfort.
