How to Measure Jacket & Shirt Length

Start the measuring tape where the top of your shoulder meets the base of your neck.
Measure straight down, over your chest and stomach, to a point on your thigh that is parallel in height to your knuckles.

To check the measurement, measure from the same starting point, straight down the length of your back, and compare the finished measurement.

Make sure the measurement covers 80% to 100% of your rear.
