In this paper, we present some sufficient conditions for which the Banach space X has uniform normal structure in terms of the Banas–Hajnosz–Wedrychowicz type modulus of convexity $$SY_X(\epsilon )$$SYX(ϵ), the coefficient of weak orthogonality $$\omega (X)$$ω(X) and the Domínguez–Benavides coefficient R(1, X). Some known results are improved and strengthened.
