Unbutton the collar and measure between the two points where the collar attaches to the collar band.
Button up the shirt and lay it down on a flat surface. Measure it from the bottom of one armhole to the other (the widest part of the shirt). Double the result for your final chest size
Hold the tape 8 inches below each armhole of your shirt to determine your waist. Measure across, from one end to the other and double the result for your final waist size.
- SHIRT LENGTH
Start from where the shoulder seam and collar connect and measure down the shirt till you reach your preferred length. If you're still unsure, an ideal shirt should reach the middle of your trouser zipper.
- SHOULDER WIDTH
Button up the shirt and lay it flat on its front. From 1 inch below the shoulder tip (where it connects with the sleeve), measure across the shirt to the corresponding point on the other side.
- SLEEVE LENGTH
Start where the sleeve meets the shoulder. From that point, measure down to the end of the cuff.
