In 1964, R. C. James introduced uniformly non-square Banach spaces, in this paper, we discussed tire non-square coefficient NS(X) of Banach space X. The non-square coefficients for spaces l^p and Hilbert spaces are calculated. Moreover, we established a relation between the non-square coefficients and the convex modulus.
