We study a generalized Dedekind sum Sχ1,χ2(a,c) attached to newform Eisenstein series Eχ1,χ2(z,s). Our work shows the Dedekind sum is rarely substantially larger than log3 c. The method of proof first relates the size of the Dedekind sum to continued fractions. A result of Hensley from 1991 then controls the average size of the maximal partial quotient in the continued fraction expansion of a/c. We complement this result by computing approximate values of the Dedekind sum in some special cases, which in particular produces examples of large values of the Dedekind sum.
