Let x ∊ [0, 1) and [a1(x), a2(x), …] be the continued fraction expansion of x. For any n ⩾ 1, write . Khintchine (1935 Compos. Math. 1 361–82) proved that converges in measure to with respect to , where denotes the one dimensional Lebesgue measure. Philipp (1988 Monatsh. Math. 105 195–206) showed that there is not a reasonable normalizing sequence such that a strong law of large numbers is satisfied. In this paper, we show that for any α ⩾ 0, the set is of Hausdorff dimension 1. Furthermore, we prove that the Hausdorff dimension of the set consisting of reals whose sums of partial quotients grow at a given polynomial rate is 1.
