Coverall Size Calculator
Enter your chest measurement and height, and whether you wear layers underneath. The calculator gives the coverall size and length, with your inside leg and the size's chest range.

Measure your chest at the fullest point, under the arms.
Coverall sizes follow chest, length follows height. A 42 in chest is a size L. At 5 ft 10 in tall that is L regular. With a jumper underneath, 2 in is added, so a 44 in chest moves up to XL.
