We extend the “naïve dimensional analysis” arguments used in QCD for estimating the strengths of operators in chiral Lagrangians to strongly coupled supersymmetric theories. In particular, we show how to count factors of 4π — an inexact science, but nevertheless a useful art when such theories are used to model real particle physics.
