We establish pointwise as well as uniform estimates for Lebesgue functions associated with a large class of Erdo s weights on the real line. An Erdo s weight is of the form W :=exp(&Q), where Q : R Γ„ R is even and is of faster than polynomial growth at infinity. The archetypal examples are where Q
