Suit Size Calculator
A suit jacket size is your chest circumference in inches, and the drop is how much smaller the trouser waist is. A six inch drop is standard, seven is a slimmer athletic cut and five suits a fuller build โ knowing your drop explains why an off-the-rack suit can be right in the shoulders but wrong at the waist.
