Looking at my average ring size maille dice bag (because my chainmail bikini is in the closet awaiting repairs ^_~), the rings are should probably be about 2/3 to 1/2 that size. If you can change them easily, it wouldn't hurt, but if you'll have to spend forever messing with seam lines, I wouldn't worry about it too much. Wire had to be hand forged when maille was made, so sizes varied quite a bit.
