You can use Inset: A = Inset[ Graphics[Inset[Style["A", FontSize -> Scaled[1]]]], {.5, 0}, Automatic, 1]; circle1 = Circle[{0, 0}, 1]; circle2 = Circle[{-2, 0}, 1/2]; Graphics[{circle1, A}, Axes -> True] Graphics[{circle1, circle2, A}, Axes -> True] The width of the inset is always 1 (in plot range coordinates). I think you'll still have to use polygonization if you want more precise control over positioning and spacing. There was a thread a while ago about displaying stacked DNA letters.
